Seireitou Kawahiru


 * "Warring with heaven, the demon with silver hair, who fights for his soul." - Seireitou-shishō

Seireitou Shōin Kawahiru no Jirō (河昼 次郎 松陰 精霊塔, Kawahiru no Jirō Shōin Seireitō) is a male Sōzōshin with a distinct Kitsune lineage, currently classified as a nine-tails; born as the second offspring of and his concubine Tsuyuri Kawahiru, the younger brother of Kamui Kawahiru and the older brother of Yukina Kawahiru. By way of this relation, he is also the half-brother of, Micythos, and Astraia. He was the first Captain of the Eighth Division in the Gotei 13, preceding Shunsui Kyōraku, as well as the Division's founder; serving as the one that laid the framework for its existing foundation. Seireitou was engaged to Senka Kururugi a month before her execution, and several centuries following this event, he was married to Shiori Miyamoto. Prior to the latter's death, they bore a son named Suzaku Kawahiru. Many took to calling him "Silver-Hairs" Seireitou (銀色の髪の純粋な魂, Ginpachi no Seireitō), among both allies and enemies, due to his natural silver-colored hair which is deemed a rarity. However, his most infamous title was earned during the events of the Quincy Blood War; named the Shiroyasha (白夜叉, literally "White Demon"), because of his demonic-like appearance on the battlefield as well as his white hair and white Captain's haori. To this day, Seireitou is still revered as the Yonkō of ; a title denoting his skill in the aforementioned craft which he seized from Yukara Shihōin. During his Captaincy, Seireitou's division members took the collective name of the "Silver-Hairs Gang" and still align themselves with him even to this day. Along with Kamui, Seireitou co-founded the Order of the Seijin, and served as one of its first three Grandmasters. These factors, in addition to his heritage, has caused Seireitou to be labeled as a "dangerous element" by Central 46. He is illustriously known as Soul Society's Hakuda Grandmaster (白打団長 (ハッカダー・グランドマスター), Hakuda Gurandomasutā; Japanese for "highest-ranked of all martial arts"). Seireitou's exploits in Yuánrǎng alongside Sun Wukong earned him a reputation as an unrivaled warrior of the martial arts, and after being acknowledged by Xuánwǔ, he was bestowed with the title "Avatar of Xuan Wu" (玄武化身, Xuánwǔ Huàshēn; literally "Incarnation of the Dark/Mysterious Martiality", referencing the patron saint of martial arts), eventually conquering the powerful Taoist deity in a bout to the death, subsequently acquiring the latter's powers and vast wisdom. During his travels in Yuánrǎng, he was mentored by the ancient dragon, Kachōfūgetsu. Within nearly every warrior circle in the civilized world, including those of the Heikai, Seireitou is honorably renowned as the God of Martial Arts (武道の神, Budō no Kami); a title which many aspiring warriors wish to seize from him in their quest for prestige.

Throughout many of his initial adventures in the series, he has faced and defeated a variety of dangerous opponents, including that of his eldest brother. Following the end of the Second Reikai War, Seireitou retired from the Seijin Council, and became the head instructor of the Kawahiru Dojang, living together with Saori Sumeragi, and his two students: Minato Kuramoto and Hinata Kusuhana. In addition, due to a significant decline in proper combat arts being taught to potential Shinigami students, Seireitou was requested by Soul Society to become a Hakuda Instructor within the Shinō Academy during "special war time" situations; a position which he has accepted and subsequently has orchestrated an advanced class so difficult that many students refuse to take it, a ploy done purposely by Seireitou so as to avoid long teaching hours. His role in the academy is most prominently shown during Bleach Restart, in which he serves as the personal instructing adviser to Kintoki Sakata, Ryūhei Kuchiki, and Satsuki Higurashi.

He appears to have a reputation within the Rukongai in the eastern lands, especially among those known as the Four Heavenly Kings, as "The Tiger of Kabuki" (歌舞伎虎, Kabukitora, though sometimes referred to also as a "fox" rather than a "tiger", given his stubbornness albeit his deceptive nature); named this for his fearsome strength as a superpower that resides in the Kabuki District and also for his well-known rivalry with Raian Getsueikirite, whom bears an opposing moniker, in reference to their standing as rivals who try to defeat one another but neither is ever able to gain the upper hand.

Appearance
Seireitou is a fairly tall, slim, and fit man with a rather youthful face despite his age. He, unlike all members of his clan, possesses dark scarlet amber eyes, and also has long silver hair with a lavendar tint that hangs near his cheeks to frame his face. Most noticeably is his eyes, which are always kept half-way opened to imply a sense of boredom and uncaring. He also had, at one time, the addition of a long ponytail in the back of his hair. He wears a white Shihakushō uniform but it is customized and partly resembles a korean-style taekkyeon uniform with an upturned collar and hakama. He now wears a long, white robe over his normal hakama. Seireitou is later seen wearing a white hakama, instead of the black ones he was last seen in. Seireitou wears his robe open in a narrow 'V' down to his waist, closed to below the hips, then open again to the hem, which falls about mid-calf. His robe has long bell sleeves, into which he hides his hands like one does with kimono sleeves. The lining of the robe and edges or layers of the under-robe(s) appear to be black. From other examples, it is likely he is also wearing black tabi with white waraji. His Zanpakutō is not visible with this outfit; however, it is revealed that he wears it on his back waist at an angle, similar to Rangiku Matsumoto.

As a Grandmaster of the Seijin Council, he wears a tannish white uniform that extends past knee-length, seeming akin to that of a tunic. To keep the tunic in place, he wears a form-fit black obi which carries his Zanpakutō on the left side of his hip. He seems to retain a form of white hakama, though much less flowing as his previous attire. His uniform, seeming like a mix of a white tunic and traditional martial art attire, is very loose; as evident from his sleeves. Over this uniform, he wears a brown cloak that is complete with a hood, extending past his ankles. His facial expression seems strange; being one of intense sternness, yet with a whimsical calmness. In the Hell Tournament, Seireitou's hair had become longer and noticeably golden, as opposed to the lavender tint he sported in his silver hair in the fight against Kamui and Datara. He had abandoned the Seijin attire he wore previously, and now dons a dark purple kimono, with a light purple cloak over this. He explains that this cloak functions in a manner similar to Raian's black tenchcoat, in that it repels the effects of spiritual pressure. Seireitou has taken on a habit of wearing tomoe beads around his neck, which was a gift from Hazuma Kawahiru, allowing Seireitou to return to the Murinne Precipice World.

While he does seem to retain the two former uniforms at specific intervals, he seems to have adapted a unique uniform similar to a combination of Sōsuke Aizen's and Gin Ichimaru's upon his rebirth, and return to his allies. Kamui notes that it is almost exactly like the uniform that their father wore during his initial reign as Spirit King. Seireitou's attire consists of white sashinuki hakama, worn only by himself and Kamui, tied by a wide black obi around his waist which keeps his Zanpakutō fastened to his left hip; unlike most obi, it's belt ends hang downwards on the left side. The top consists of a thin white dobok, which splits downwards and apart evenly. Over this, Seireitou wears a long white robe that has similar bell sleeves to Ichimaru's former uniform. Leading up to his shoulders, both sleeves sport a thick long black bar running down the length of each white sleeve; these black bars are also shown to be on his hakama, running down the length of his legs on the outer edges. Similar to Aizen's uniform, Seireitou also possesses a white collar that is kept up, but only block the view of his chin area. The black bars that extend to the shoulders also run up the collar on each opposite side. It should also be noted that Seireitou's expression with this new appearance is more calm and peaceful, with an air of humility, further confirming that he has settled his despair. He later adapts a clothing style similar to the chinese shenyi.

After the nineteen-month timeskip, following Seireitou's reappearance in the series, he sports a similar appearance to that of his former attire nineteen months ago, with the addition of small armor plates around his shoulder. He has facial hair, in the form of a mustache and chin-hairs, almost similar to that of Shunsui Kyōraku. Despite his haori appearing to be very similar to his former one, Seireitou explains that the haori he wears is the one that Shōyō meant for the successor to the Seiten Shiranui-ryū, and that the one he wore nineteen months ago was merely a replica of the original haori. Unlike the replica, the real haori is crafted from a very rare material that is nearly impossible to find. The purpose of the armor plates are unclear, if they serve any. Underneath, Seireitou wears the same kosode that was worn by Shōyō in many of the flashbacks regarding the latter. These plates were later replaced with silver armour metal plates on both of Seireitou's shoulders that appear as collars surrounding his face and extend outwards down his arms, while also adding the metal band around his waist which connects to three individual silver armor pieces hanging from the front of his waist and on both sides of his hips; similar to the entire armored attire worn by Kyebaek Tae, which is said to be worn by "warlords of Soul Society's history" and may represent the assimilation of the "Shiroyasha" persona in its entirety, according to Saori Sumeragi.

Personality
Without a doubt, Seireitou is possibly one of the most unusual characters in the series. He appears to shift from a wise master of the Shinigami arts to that of a naïve child that claims to have the soul of a boy within a man's body, back to that of a warrior who has faced down death his entire life and spends his days reflecting on those experiences, reverting to a man with the spirit and youthfulness of a young boy. Essentially, Seireitou prides himself in "being simple", and would often cause others to believe he himself is simple-minded. Yet despite how simple minded he appears at first, Seireitou would reveal himself to be a complex person with rather difficult to figure out views. One of the more noticeable traits of Seireitou is that he tends to act out of character, portraying traits of a manipulator like Sōsuke Aizen or the suspicious traits of a sarcastic man like Gin Ichimaru. Tetsuro Ryuzaki commented that Seireitou is unpredictable, and it is almost impossible to discern his thoughts or his motives. Seireitou himself claimed that his main characteristic is being "uncharacteristic". The only one who seems to understand his actions, most of the time, is Raian. In addition, despite his personality having different outlets, the one thing that has never changed in him is the beliefs that he lives his life by. While most appear to be very trivial, there is one that stands out the most, and serves as probably the most characteristic piece of who he is. Seireitou is a firm believer in the principle that the only thing worth protecting is "one's soul", a teaching that was passed down by his teacher, Shōyō. He believes that no matter what happens, so long as his soul exists, he can never be defeated. This unrealistic level of indomitable spirit allows him to overcome challenges that initially appear to be futile. Perhaps an extension of this belief is derived from the promise that he and Raian had made in the past. They had promised to never allow the other one to deter from their path, and if one of them should, the other would kill them. Seireitou states that this way of life is how all four of them, the Yonkō, have dealt with each other all their lives.

Using a medley of quotations (some of which appear not to have much meaning to them, or are merely used at random moments, having almost nothing to do with the situation), he has shown a remarkable ability to consistently shatter the perceptions of many people that he confronts but never appears interested in making someone, as he says, "see things his way". An example of this is that he had stated that if two people share very different views, its better they go their separate ways instead of attempting to reconcile matters. His knowledge of people's true personality appears to go beyond being simply a good judge of character. Despite Kamui's background as a threat to peace, and strong incriminating evidence, Seireitou trusts him with many important tasks. In addition to Seireitou's great trust in the power of one's soul, he also had a deep understanding of the power of love. This perhaps stemmed from the loss of his dearly beloved wife, Shiori Miyamoto, whom he lost in battle to Datara Kawahiru. He possesses incredible insight on people, often knowing if they are troubled or hiding something; he sometimes even knows what a person is thinking, scaring even Raian with his powers of perception. It is hard to recognize this wisdom due to his almost constant shift in attitude, usually displaying immature and childish trains of thought and actions, but it is through these misunderstood guises that his true self shines through in a most dazzling manner.



Adding to his potpourri of randomness that he considers a personality, despite his talk of morals and honor, Seireitou appears to be very willing to commit actions that would be considered criminal offenses. This makes him appear very hypocritical and he will attempt to justify his actions with several excuses, most of which appear not to really make any sense. When such thoughts are in his head, he reveals it through "evil"-like facial expressions, although these are very rare moments and usually serve only to unnerve an opponent. Despite resolving never to kill, he is shown attempting murder on more than one occasion. In addition, he has a habit of hitting people, even those he doesn't know, for very loosely-justified reasons; an example of this was shown when he met his Reigai version, when he slammed the latter's head into a concrete wall without even questioning the situation. This serves to exemplify that Seireitou is very open when it comes to feelings of annoyances, and will not hesitate to act on them. Moving on with his odd traits, Seireitou constantly uses many forms of innuendo in his speech, especially in the sexual manner, in his statements, annoying allies and enemies alike. His typical way of being very inconsistent with his actions gives off an initial impression of being heroic and honorable, later on revealing his motives to be self-serving. While infamous among many of his colleagues and subordinates alike for the selfish and narcissistic aura he gives off, but to those who truly know him, he is a man that always attends to those who need him. In the former regard, he and Kamui are considered the exact same. Although this immature persona can appear to be a negative trait, it is also seen in a more playful light. Subsequently, he is sometimes seen as "tongue-in-cheek" comical, and to another extent, very serious about his family and friends. He typically acts in a goofy, energetic and fun-loving manner, able to cheer up even the depressed Raian at times. Despite these traits, Seireitou is capable of easily frightening anyone when he is upset or enraged, sharing a similar trait with Saori Sumeragi. In regards to his eccentric behavior, Raian states that Seireitou has went through several painful events in his life, going on to say that his inability to protect many of his comrades in the the Quincy Blood War still haunts him, and as a result, he is very protective of his current friends. When someone close to him is in danger, Seireitou has no qualms about putting himself at risk to save them, if necessary, as seen when he prioritized the safety of Raian and his group first, over confronting Kamui head-on when his group confronted his entourage. Raian once mentioned to Hibiki Asakura that he "had lost count of the amount of times I [Raian] have wanted to destroy the world so that it could be reborn. But he's [Seireitou]... He's enduring it. He should hate this world more than any of us, but he's putting up with it." This statement was meant to refer to Seireitou's ability to wade through the experiences he had been dealt and still keep moving on with his life.

Seireitou's almost immature and free-spirited personality masks his sage-like and serious attitude, appearing in him when the situation demands it, accompanied with wisdom that has been attained through years of experience; this may be a contributing factor as to why many commonly acknowledge him as the "Fox Hermit" (狐仙人, Kitsunesennin; literally "Kitsune Sage"). Some state that he is probably unaware of this immaturity. However, Seireitou seems to give off the implication that he is aware of it, claiming that he acts in the aforementioned manner to keep matters around him from getting "too depressing". Raian, however, comically stated that Seireitou had suffered heat stroke at some point in his life. When appearing to be serious (although the term is used loosely), his statements still belie some sense of dry humor and even sarcasm. Seireitou appears to act mostly out of self-interest rather than any sort of philanthropy, whether the situation be trivial or life-threatening. As both a Captain and a former leader of the Order of the Seijin, he comes off to most as a sort of cocky layabout, shirking most of his duties. Seireitou is expertly manipulative, prone to think several steps ahead of those around him and giving him a remarkable (almost annoying) talent for making subordinates act exactly as he wishes despite appearing not to have had a hand in their decisions. However, while these traits do have a place in his real personality, much of his outward persona can perhaps be considered an intentional facade perfectly designed to cause those unfamiliar with him to underestimate his remarkable intelligence and ability. At the core, he is a remarkably devoted commander whose primary focus and personal duty is to his friends and family. Though he hides it well behind a veil of cynicism and self-importance, Seireitou is a man who cares deeply about the people who trust and support him and goes to great lengths to ensure their safety and well-being, even at the risk of his own. As a man with considerable power, Seireitou considers himself a protector to those without and acts accordingly, earning the staunch loyalty of his most trusted compatriots. Despite his numerous complaints of having to lead, he has definitely shown himself to be a great leader. Seireitou has always been able to command the forces of the Gotei 13 in the battle against Datara, despite the seperation of their ranks. In many ways, according to Izaya Kondō, he represented the strength of the old Shinsengumi; steadfast, selfless, and modest. Kamui, in several instances, has professed to having difficulty to differentiate from Seireitou and Shōyō.

As stated by his older brother, Seireitou's most remarkable ability is his will to succeed, pushing himself beyond his limitations, and never giving up even when the odds are stacked against him. Seireitou, for the most part, only fights to win, and usually will spare his opponents, despite initially claiming that he'd kill them. His will to win is often bordering on the extreme, displayed by the bright white glow of spiritual energy that emit from his eyes during such moments. In contrast to this, he appears not to bear much regret to when his opponent has died, whether by Seireitou's own hand or because of other reasons. His staggering power is simultaneously reigned in and enhanced by his fierce unshakeable conscience and indomitable spirit. Seireitou seems to be proud of his own power, but unlike Datara Kawahiru, he seemingly possesses no physical signs of arrogance or overconfidence. This great strength appears to have a hand in his interest in facing powerful opponents, subsequently contributing to an inability to turn down challenges, especially when it concerns a powerful opponent; although regardless, deep down, he is a man of peace, a trait that was influenced by that of his teacher. Although he is a fearsome fighter with nearly unmatched skills, Seireitou will typically use the guise of a coward most of the time to avoid needless bloodshed. However, in complete contrast, he is in fact willing to risk his life for almost anyone. He is typically described by others as lazy, unmotivated, and useless. Although, those same people also seem to note his kind, responsible, and unpredictable self. Despite the fact that he would normally act as a coward and allow others to handle problematic situations, Seireitou is quite aware of the fact that his power outmatches many of those around him and would not hesitate to remind others of this fact. Seireitou has shown himself to have a habit of referring to fighting as "dancing", using several dance metaphors throughout battle. Raian notes that one possible reason for this is because martial arts have always had a strong connection with dance and song.

In the position of an instructor, Seireitou is known to be capable of unspeakable brutality, both physically and mentally. Furthermore, he isn't very considerate of another's feelings of self-adequacy lack-there-of, portraying his signature sarcasm. It was because of this, coupled with his amazing capabilities as a teacher, that among those who have either trained under him or have heard about him as a mentor address him as the "demon teacher" (魔性使い, Mashōtsukai). According to Saori Sumeragi, whenever Seireitou says "Eh, I don't want to.", his stubbornness becomes unrivaled to the point where no amount of compensation can change his mind. His role as a teacher stems from his deep respect of his teacher Shōyō Shakyamuni, and out of memory of his teacher, he values the relationship between a student and their master above all others; becoming enraged that someone who would harm their student would call himself a teacher. In the "less-platonic" sense, Seireitou has considered himself an expert on women. The truth of this is very difficult to ascertain, as he seems to understand a great deal about a woman's thoughts, but at the same time reveals himself to say and do things that are inconsistent with his knowledge. This can be seen by the way he "mistakenly" insinuated Hisaya Urogataya's statement to mean that he, her, Jacqueline and Okiko could have a foursome; responses of which often tend to lead to death-filled stares from the women mentioned, save for Okiko in that particular scenario. Regardless of this ability, he is not one to commit to intimate relationships, most likely being a result of Shiori's death and the events that transpired from it. Nonetheless, he was more than adept at sweeping women off their feet, even if it wasn't intentional. Almost contradictory of this, however, Seireitou appears to be very willing to commit perverted acts, being labeled by many as a pervert. His normal use of dirty talk, scatological innuendos, and ability to find women in unstrategical places also seem to suggest this. In contrast to this, Seireitou is often considered by many to possess a very peculiar charisma that sets him apart from all others. A unique charisma that is disguised by his strange mannerisms and ridiculous actions but has always remained true and just.

However, it should be noted that just as he demonstrates a darker side to him in terms of mentoring and combative situations, so too is there a maliciousness in how Seireitou deals with women he has personally noted to have taken an interest with. Ever since Shiori's death, the term "love" does not register to Seireitou when speaking of relationships that are not some form of parental relation or a master-student bond. Whether he does seek it and can not recognize it, or simply refuses to pursue it, still remains unknown, but what is clear is that throughout his life, he had slowly begun to delve deeper and deeper into his Kitsune self. One of the key aspects he demonstrates of a Kitsune is his extreme sense of being territorial. When there is a woman he has taken some form of interest in, usually that of a sexual nature, he pursues the woman like a predator hunts his prey. He loses interest if the woman is too willing but if there is a chase, he will continue deepening the pursuit until his Kitsune instincts finally are brought to the forefront that he seizes them as his own property; usually through repeated sexual conquest. While in the beginning, it was losing himself to his carnal Kitsune instincts that eventually led to the horrible mistake of him killing his beloved Shiori, in his despair and subsequent acceptance, he became at peace with his Kitsune self and those deeper instincts are now his completely. Even so, having forgone love as a forlorn enterprise, marking his territory via sexual consequence is how he establishes any sort of relationship with a woman that has piqued his interest. That being said, women like Saori and Botan Nakandakari hold a more special place in Seireitou's mind; to such a degree that he has come to accept them as close friends and comrades rather than perceiving them as sexual prey. That being said, even past females that had once worked together with him can eventually be turned into his prey; the prime examples being Kimiko, Sakura Hazumi, and Asaka Miyagi, all of whom succumbed to their deaths following the ravenous encounter. If the pursuit of the woman was one that satisfied his instinctive drive for a challenge and the eventual seizing of said woman was worthwhile, he will opt to continue revising them as many times as he wishes; continuing his ravaging actions until the encounters can not continue for some apparent reason. It is unknown how he goes about these pursuits, though simple assault does not seem to be an impossibility. While in some cases, these encounters led to the deaths of some of his partners, for one reason or another, and other situations have led to Seireitou simply losing interest (such as Amaririsu Itami), very few cases actually did result in the target woman actually falling to their own carnal desires and eventually succumbing to them as they welcomed the silver-haired man's repeated advances. Notable cases in which this latter result occurred would include Sara Miyake, Megumi Shimokawa, and ; the two former examples of which eventually led to their deaths due to eventually be smothered by Seireitou's spiritual pressure enhanced by his lust while the latter of whom resulted in the procreation of Sayuri Matsumoto. At one time, this aspect of his personality could be attributed to his innermost Shiroyasha, but it is arguably more tame as Seireitou never lowers himself to senseless violence during these pursuits. Nearly a century after Shiori's death, when he first began expressing his Kitsune instincts, he had sought out numerous females in both the and. It appears as though his current person of interest in this regard is Captain of the, Rikuri Ukitake, though any progress of this endeavor has remained to be seen.

Among his hobbies, one of the ones he appears to have a consistent interest of indulging in seems to be playing board games. Whenever he is by himself, he sets up a chinese Go board, and utilizes the pieces of the individual games of Chess and Shōgi. setting up a very twisted game that combines all of the respective games' aspects. They seem to form a physical representation of all the situations occurring around him, allowing him to formulate potential plans for said situations. The rules he plays by are also beyond that of normal, seemingly standing as a metaphor for the way he lives his life. However, this could just be a dramatic implication, as when Seireitou was once annoyed by something trivial, he proceeded to kick the board at Raian's head. He also appears to have an obsession (or addiction) for sweet foods, once threatening to kill whichever one of his two students ate the last ice cream sandwich. This also seems to carry over to alcoholic drinks such as sake.

It has been noted by both Kamui and Sōkudo that Seireitou houses two different persona. The first is his carefree demeanor, which is present consistently and makes up the majority of his personality and traits. This is often characterized by his moniker, "Silver-Hairs" Seireitou. However, Seireitou also possesses the trait of a brutal and unmerciful killer, characterized by his other moniker, Shiroyasha (白い悪魔, White Demon). Sōkudo claims that these two persona are at war within Seireitou, and have been ever since the death of Shiori Miyamoto. However, despite this claim, the "white demon" persona has been depicted several times before, most noticeably during the Quincy Blood War, when he was first given said title, and also shown whenever Shiori is brought up in a negative or demeaning manner.

Shiroyasha Persona
Through horrific circumstances throughout his life, having fought in a horrendous war and watching his beloved executed before his eyes, Seireitou had developed a sort of secondary personality within him that would rise to the surface whenever he would experience intense feelings of rage or sadness. Kamui, however, noted that this change in persona is most likely a reflection of his primal instincts due to the Sōzōshin blood coursing in his veins. While at first, Seireitou appeared to be completely unaware that he took on this sudden change, most likely due to being blinded by anger, he seems far more in control of these changes and aware of his actions during.

Whenever overcome by his Shiroyasha persona, Seireitou's personality utterly changes. He is no longer humorous nor eccentric, but instead becomes serious and apathetic. It is likened to that of Kamui's constant facial expression, exhibiting an immense shuddering aura of coldness from the depths of his eyes as noted by Raian Getsueikirite, whom could not read Seireitou's heart whilst the latter was in this persona, despite the bond the two share as friends. Raian described it as a strange and foreign darkness that surrounded the man's being, completely unlike that of Seireitou, while Saori Sumeragi expressed a fear so great that it threatened to overwhelm her and crush her entirely. Most noticeably, he develops an intense sadism that carries over into his conversations and even in his fighting. He demonstrates a complete and willing desire to preform certain acts during battle that would disgust or frighten almost any sort of opponent(s), such as castration and sadomasochism, to a point where it appears as though he finds some form of enjoyment and sexual ecstasy in seeking to preform such actions. Though generally wishing to inflict torture onto an opponent using his blade, he'll use his fingers to stab through an opponent's body and pull out a specific organ, such as aiming for the neck and pulling out their larynx or ripping out their spine part by part through finger-tip thrusts. He is willing to go as far as to tear off the reproductive organs of a male and shove it down their mouths or causing the sexual organs of a female to bleed out violently until they slowly pass out from hypotension shock and brutally violates their body. While doing so, his face reveals the incredible sense of pure ecstasy that he feels in the form of a frightening grin, doing everything possible to an opponent by forcing out every ounce of sickening pleasure and thrill he can from torturing them before utterly killing them in cold blood.

History
Born to the Kawahiru Clan as the third son of the King of Souls and Tsuyuri Kawahiru, Seireitou had never gotten to appreciate the benefits of being a full-blooded member of Soul Society's royal family. An incident had caused the young child to become expunged from Reiōkyū. Seireitou grew up under the care of Shōyō Shakyamuni, and was under the belief that his parents had abandoned him, though Shōyō attempted to persuade him that this was not the case. However, Seireitou continued to think this way, and as a result, he was apathetic toward most people in Rukongai who attempted to get close to him. Seireitou was raised in a dangerous era, war and conflict being a common sight in the Rukongai districts and beyond them. The fighting appeared to not have even a single instance of any ceasing. Under Shōyō, Seireitou became part of the Shintai Sonjuku school and studied under his mentor and father figure for most of his childhood and teenage years. While learning at the school, Seireitou eventually met Shiori Miyamoto, whom was studying under Shōyō around the same time as the former. The two, although meeting with a rocky start, became good friends who relied on eachother in tough times.

Under Shōyō, Seireitou had been taught all forms of Shinigami combat and how the four intertwined with eachother. Despite their differences, the combat styles all relied on eachother's teachings in one form or another. Once his initial training was finished, Shōyō would have Seireitou participate in missions that were in service to the warring districts. Because his experience was limited, many of his tasks were limited only to bodyguard duty and parcel deliveries. He often worked with Shiori, as they were quite the excellent team, but also had to work together with other students of Shōyō's. Senka Kururugi soon came into the picture, who's parents were nobles of the Rukongai village. Despite their interactions being limited, Seireitou and Senka began to develop feelings for eachother, to which Shiori showed contempt toward.

Before long, Seireitou had followed Shiori's example and entered the Shinō Academy, pending Shōyō's approval. At the Shinō Academy, Seireitou was admitted into the lowest class, being discriminated against as "scum of the Rukongai", along with Shiori and Raian. However, the trio proved themselves, and eventually were admitted into the top classes respectively. It was at this point that Seireitou and Raian began their rivalry, attempting to best the other in each class. Despite the two's equivocal skill in Kidō, Seireitou was able to best Raian in almost every class, earning perfect scores when Raian earned average scores. Handpicked from a class of other top students, Seireitou was assigned to receive special instruction. His sensei was Shōyō, his surrogate father, which surprised the young man, to learn that his caretaker was actually his teacher. Seireitou became even further distant from Raian when he met Kamui Kawahiru, Shōyō's assistant teacher who was also the current Captain of the Ninth Division. However, Kawahiru revealed that he was actually Seireitou's older brother during their one-on-one training. Seireitou inquired why their parents had abandoned him, Kamui explaining that their parents had become involved in a civil war, and in order to protect their son, they had Shōyō take Seireitou to the Rukongai. Kamui goes on to say that because of this war, both of their parents were killed on the battlefield. Seireitou soon confronted Shōyō about this, but Shōyō refused to tell Seireitou anything, and because of this, Seireitou soon began to feel detached from his surrogate father.

Seireitou held only Kamui in regard from that point on, and accepted the latter as his mentor. He formed a powerful bond with his older brother, but also a bitter rivalry. Kamui acknowledged the rivalry Seireitou felt, telling him, "We are brothers. I am the wall you must climb over, so you and I will continue to exist together." However, it was not long after that Seireitou began to see Kamui's true colors, discovering that everything he had told him was a lie. Kamui was forced to leave his captaincy under personal reasons, and confronted Seireitou, attempting to kill his younger brother. However, Shōyō came to his rescue, and chased Kamui off. Shōyō explained that he didn't want to tell Seireitou the truth, because it would have devastated him. He explained that Kamui was the one who led a massacre of the Kawahiru family, and killed his own parents. Sindae, realizing Kamui's intentions, requested that Shōyō take care of Seireitou. It was later revealed that Sindae managed to drive Kamui off, and the latter disappeared completely that night. Seireitou apologized to his mentor for making such a mistake, but Shōyō forgave him. This event deepened Seireitou's despair, but ended up deepening his relationship with Shiori. Before long, Seireitou and Shiori shared their first kiss.

The years then passed, as Seireitou graduated top of his class, and was placed in the Gotei 13 as the fifth Seat of the Eighth Division. He served under Captain Nagato Hiroshitaki. He formed a close relationship with his Capatain, but eventually ended up being the victim of betrayal yet again. Nagato revealed his true identity as Myoken, and attempted to use Seireitou to kidnap fellow Shinigami for experimentation. When Seireitou refused to comply, Myoken had attempted to kill the young silver-haired man. However, the combined efforts of both Seireitou and Shiori defeated the renegade Captain, and ended up running him out of his position. Pending an invesigation, Seireitou was acquited for his charges for insubordination. With nobody better qualified for Myoken's former position, not even the lieutenant at the time, Seireitou attained the captaincy of the Eighth Division. This was because sometime before his fight with Myoken, he attained his Zanpakutō's Bankai.


 * "One hour, Sei. One hour to escape the hangman's noose."
 * "Escape? My favorite two-syllable word."
 * - Raian and Seireitou

As the new Captain of the Eighth Division, Seireitou took Shiori as his lieutenant and Setsuna Inoue as his eighth seat. Senka had attained the captaincy for the Second Division, and Raian obtained the captaincy of the Tenth Division. Seireitou and Senka's relationship began to flourish from when they were kids, but Seireitou was more of a bachelor, hitting on women all throughout the Seireitei. Things were finally at peace, as Seireitou worked with his comrades on several assignments. It was during this time that Seireitou took on six disciples, five of which would go on to found Kōmyōzankū. However, eventually, war approached. Seireitou had worked alongside his fellow comrades, including Hikaru "Shadow" Kurosaki and Sōsetsu Taneda. After almost an entire year of non-stop fighting between the opposing sides, the Shinigami were the decisive victors. Two years after the war, Shiori worked her way up to the position of the Fifth Division's Captain. The lieutenant position was open, as Seireitou appointed a man named Akujin. Even from the beginning, Seireitou had held suspicions about Akujin, not felt by his fellow Captains. However, these feelings were soon made out to be fact, as Akujin was caught red-handed by Seireitou and his comrades, undergoing Hollowfication experimentation. Akujin used this oppertunity to force the Hollowfication virus on the group, causing them all to undergo Hollowfication. Akujin was in leagues with the Fifth Division's fourth seat, Sōsuke Aizen, the latter being unknown in his involvement until later. Before long, Seireitou's group was found by the Ninth Division's squadron, and brought before the Central 46. When Seireitou was put on trial for gaining Hollow powers, he was stripped of his captaincy and sentenced to death. Just as Seireitou was about to be killed on the spot, during the execution that followed a week after the trial, Raian intervened and freed his friend, as the two attempted their daring escape. Raian led Seireitou to the outskirts of the Rukongai, where the others were also waiting. Because Raian's identity wasn't revealed, he stated that he'd stay back and keep an eye on Akujin. Now outlaws, Seireitou and his group were forced to flee to the World of the Living, not before Seireitou thanked his friend for his help in escaping.

They were hunted however, ironically by Raian's own division, causing Seireitou and Shiori to lose contact as they were forced to split off. Seireitou had not known what had happened to Shiori, as he made his way to Karakura Town. He used Kidō to hide himself, until he had crafted a Gigai that would cut off his spiritual power. He soon took up a job as a High School teacher, and settled into the life of a human. The life of a Shinigami, however, did not escape him. He soon made contact with former Captain, Shinji Hirako, a few years later. The two discussed the occurances reguarding both of their defections, only to come to the conclusion that Akujin and Sōsuke Aizen had been working together, side-by-side on the experiments. From there, the two Vizard had decided to work alongside one another in defeating both Aizen and Akujin, and clearing their names. It was also around this time that Seireitou encountered Sōsetsu Taneda once again. Seireitou had also begun to make plans to find his brother, Kamui, in the hopes of making the mysteries of his past finally come to light.

Equipment

 * Hanullim's Sheath (シースされて究極の, Hanullim no Saya): Hanullim's sheath can deflect or resist spiritual energy attacks with the barrier used to contain its power. However, the sheath can only withstand a limited number of attacks. The sheath is capable of resisting any amount of offensive force; however, if that force is used continuously then the sheath will crack. This is why it was able to hold off Raian's Zanpakutō on its own, since it was an attack that was only unleashed once, but couldn’t hold off Kamui's Kidō since he was unleashing them constantly. The sheath can also summon Hanullim to itself, as seen when Seireitou was trapped inside the cage of kidō with only the sheath. It was created from an ancient tree bark that grows only in Asadal. Though Seireitou no longer wields Hanullim as a blade, he is known to keep the sheath itself at the ; however, he did at one time claim that he threw it out after "spilling hot miso soup" all over it.


 * Reiryoku Seals: Generated by a Kidō created by Seireitou, both himself and Minato Kuramoto wear these special seals around their wrists and ankles, reminiscent to that of cuffs. These serve the purpose of sealing the wearer's internal reiryoku as well as their reiatsu, while also making the use of physical movement impossible. Ideally, these cuffs act like weights which make it nigh impossible to move unless the wearer actively cycles spiritual energy throughout their entire body, allowing them to move. However, because Seireitou is not a physical being (as his body is composed of reishi), the cuffs do not hinder his physical abilities to the same extent they do to Minato, as the latter is a human being, but still appear to limit the former's strength and speed by a significant amount, to almost one-fourth of his true capabilities. These cuffs are typically meant to seal away a massive bulk of Seireitou's spiritual power (initially being said to limit him to one-tenth of his normal energy levels). According to him, the seals react to even the slightest amount of spiritual energy used by Seireitou, as their purpose is to restrict the enormous concentrations of power within him; their weight immediately increasing to nine hundred thousand nine hundred and ninety kanme (roughly over three million kilograms). By unlocking the seals, he can release the full extent of his spiritual power. When the need for his maximum power has ended, he will reseal himself with the cuffs. After his training in Asadal, the effects of these cuffs were enhanced onto Seireitou by an unknown extent.


 * Mysterious Jewel: Seireitou carries a strange jewel on his person which is shaped like a diamond with an extended body, holding a lavender-purple pearl in its center. The jewel has the number one imprinted on its side, for unknown reasons. It appears that it was given to Seireitou by Kamui, but the purpose of this jewel remains unknown. Kamui implies that it is a special item held by Kawahiru heirs.


 *  (천주학 (睿智天の原), Sōhaku; Korean for "Heavenly Learning"; Japanese for "Wisdom of the Heavens"): The of his mentor and grandfather,, Seireitou procured the blade after his master's death and has kept it within the confines of  to this very day as his most precious treasure and keepsake. It is a standard katana with a dark brown hilt with a white diamond design that runs up and down the hilt. Its crossguard is shaped like four gold flower petals, circling around in between the blade and the handle. Though the spirit within the Zanpakutō has long since passed away when Shōyō had left this world, due to their incredibly close relationship, Seireitou has noted that he can often feel remnants of his master's presence within the blade. He normally conducts his occasional meditation ritual while sitting before the blade itself.

Powers & Abilities
"How long has it been... since I've seen him in this state? How long has it been... since my body has been struck by a fear so abyssal and encompassing as the depths of the sea? A spiritual force so exorbitant that it scorches the heavens and frightens even the clouds... The path carved by his blade, renders all of the world unto smoldering decay. Those eyes haven't changed. They're the same as they were back then. The eyes of a demon. That man who stood on the battlefield, with piercing yellow eyes and his silver hair tainted with the blood of those he killed... Whose name stuck fear into the hearts of every enemy... Shiroyasha, the white-maned demon. Kawahiru Seireitou."

- Raian Getsueikirite comments on Seireitou's Powers By his standing as a former Captain of the Eighth Division, and as one of the four Yonkō, Seireitou's power and abilities are said to be unrivaled by anyone who came before him or anyone since. During the Quincy Blood War, flee-on-sight orders were given should the enemy ever see him appear on the battlefield; even to those brave souls that dared to confront the man, the very presence of the silver-haired Captain caused all of them to cower in fear, prompting them all to subsequently attack him at once for their lives, only to end in a bloody massacre. His abilities, as of now, have advanced to the point that even Hanzei Kurokami believes that no one of the current generation will be able to surpass him, and that he has become equal to his teacher, Shōyō. Seireitou's overall power and infamous status are so great that his name alone is enough to incite terror in those whom would be considered his enemy. He proved to be so overwhelmingly powerful that without even using the full extent of his power, he was able to nearly kill several opposing Sternritter from both the past wars and the thousand-year following conflicts, stand toe-to-toe with Genryūsai Shigekuni Yamamoto single-handedly (though the elder was also holding back his full strength), and easily overwhelm multiple Captains of various generational ranges in their Bankai states with ease, leaving all those who served as witnesses in awe at his might.

Transcendent Spiritual Power: As one of, if not the strongest Sōzōshin alive, Seireitou possesses absolutely monstrous spiritual power. According to Sorata Nekoi, Seireitou's reiatsu has an overbearing power which is unlike anything or anyone else in Soul Society, to the point where he even considered as something completely unrelated to reiatsu. His spiritual power has a presence which, according to him, feels as if it's trying to stifle his very existence. Koga Tensei compared the feeling of Seireitou's reiatsu as if the "weight of the skies" were on his shoulders. In terms of coloration, his spiritual energy is pure white, occasionally producing lavender bioelectrical sparks of reishi discharge, making a deep crackling noise when Seireitou focuses his energy. His body glows bright white when this is preformed, as his energy interacts with the energy in his surroundings, changing their properties in a very minimal way, most likely due to his Zanpakutō's nature. Similar to Raian Getsueikirite, when unleashing a strong enough surge of energy, Seireitou's reiatsu will often take the appearance of a fox's head. His very presence can cause even the most skilled warriors to lose their breath. During his battles in the war, Seireitou's moniker, Shiroyasha, was evident the moment the former entered battle. The sheer force of his spiritual energy raining down on the battlefield, the enemies staring on in a mix of fear and despair, as the Shiroyasha's very spiritual power would be the first wave of attack, followed by the onslaught. Allies alike would watch on in absolute shock, being enveloped in an "ocean of energy" that would surround them entirely. Seireitou's spiritual pressure has the additional effect of affecting entire areas to the point of disrupting energy attacks from enemies, as well as affecting others from seemingly miles away. Eventually, during the years following his resignation as a Captain, Seireitou's training had elevated his power to the point at which allowed him to contend with Datara Kawahiru on an equal level. However, there was something new about the white-haired man's spiritual power. As he spent a century together with the Dragons, his own spiritual nature became far more aligned to nature, developing a far more tranquil feel to it that would have no effect on the area around him. In being tied to the natural world around him, Seireitou's own energy would give life to his surroundings, allowing plants and flowers to bloom forth in conjuction with his will. Swearing to never allow himself to harm nature, and toiling in the forests and fields for an entire century, nature itself rewarded his devotion by granting him its protection; something which manifests itself in a variety of ways, most commonly so by allowing Seireitou to gain energy from his natural environment. Furthermore, it would possess a sort of healing effect toward those around Seireitou whom he favored as comrades, though this healing ability would influence him the most. Merely releasing a degree of spiritual pressure from his centre would be enough to slowly heal and recover from even grievous injury. Following the nineteen-month timeskip, Seireitou's spiritual power has risen further, prompting Hanzei Kurokami to compare the former to Shōyō in the latter's prime. The overwhelming levels of energy that Seireitou obtained prompted him to use special "reiryoku cuffs" to seal away a large bulk of his full power, hindering him to one-tenth of his true capabilities. Training under immense gravitational pressure in Asadal resulted in Seireitou's spiritual power levels to rise exponentially, though the full extent of his spiritual power at this point is unknown. Despite his full power being unknown to all those around him, Raian noted that his current power, with the reiryoku seals active, is almost equal to that of his unsealed energy level prior to his Asadal training. Considering that the reiryoku seals themselves have been enhanced to seal even more energy from within Seireitou after his training only hints to an absolutely god-like amount of energy that is sealed within his being by the new cuffs, waiting to be released at the moment Seireitou deems the power necessary. Unlike other individuals, even among those of the highest skill class, Seireitou's spiritual power reached peaks where it no longer manifests in the same manner that spiritual pressure normally does, as it instead appears as a coat of shimmering white energy of almost mystic properties. Seireitou claimed that his power at this stage reached a degree that his training with the Dragons finally presented itself in its entirety. Therefore, it can only be inferred that his power is akin to that of the natural world and even the cosmic energy filling the universe. While his energy can still be felt, it has been stated that it would be pointless to attempt gauging the level of Seireitou's power, as it possesses the same attributes as nature itself; so vast that it can be simply regarded as immeasurable, that any individual that tries to sense the depths of his power will only find themselves lost in its vastness.


 * Fear-Inducing Reiatsu: When in his Shiroyasha state of mind, just as his entire alignment changes, so too does the nature of his very reiatsu. It literally inflicts all those who feel the force of Seireitou's reiatsu with a deep sense of fear, slowly forcing them to surrender their composure to instinctive fear toward Seireitou himself and everything around them, causing those who feel the brunt of the spiritual pressure to begin allowing despair and doubt to seep into their minds and forces them to unintentionally lose control of all rational thought. He can even make victims suffer through hallucinations of all sorts of things, such as swords being thrust through their necks or the limbs of their body being ripped off. In most cases, such intense fear thrown at a normal victim would result in instantaneous death, their heart being incapable of dealing with a shock of such intensity. However, an individual's willpower can be used to resist this fear-inducing reiatsu to an extent, but it seems that even the strongest of opponents eventually succumb to the fear in direct proportion to the length of time they spend under the influence of the Shiroyasha's spiritual pressure.
 * "White Curse" (白の呪い, Shiro no Noroi): Not Yet Revealed


 * Mastered Reiatsu Control: Through years of training and battle experience, coupled with immense levels of self-control and tempering of his spiritual prowess through, Seireitou possesses a nearly perfected form of control over his spiritual pressure. He is capable of exerting his pressure outwards as a feint, with such potency that most common opponents are fooled into believing he actually preformed an action. It has been shown that merely glaring into the eyes of an opponent is enough to render their confidence and composure asunder to the point of collapse. He has also demonstrated rather unorthodox methods of directing his spiritual pressure for unconventional purposes, such as imbuing a small part of it into the patchwork of an enemy's Kidō spell, yielding a brief disruption in its uniformity, in order to utilize his reiatsu as a sort of scouting probe; with the purpose of gauging the properties and quality of the spell's nature as well as the level of threat it presented. The true extent of his reiatsu mastery and control is derived mainly from his absolute self-control; a requirement of a true Hakuda Grandmaster. No longer is there "spiritual pressure" and "the body", but rather, the two have become one; they have unified into a single entity. The entire scope of Seireitou's reiatsu is his body, in that it can be directed in the same manner. It becomes possible to actually manipulate one's reiatsu in order to utilize it as they do their own body. By reaching out, Seireitou can literally strike opponents with concentrated amounts of spiritual pressure, as though it were his own hand, and likewise, he is capable of grabbing onto desired targets as though he were holding something in his physical palm. In doing so, it is possible to wipe out an entire battalion of foes using only concentrated amounts of spiritual pressure; enacting several martial art techniques from a distance using his own body as though he were a puppet master; his reiatsu being an extension controlled from the core that is his physical body. While Hakuda conducted in this manner is effective for most enemies, it pales in comparison to the tremendous force of his Hakuda when done through his own self.

Immense Strength: Perhaps due to years of combat experience and time on the battlefield, Seireitou has a very large degree of physical strength, most commonly displayed by his ability to fight back his opponent's attacks with a single arm. Repeatedly, he has shown clear evidenced of his strength from acts like kicking Hikaru through a building and slamming Ryan over his shoulder with one hand in their battle, as well as when he grabbed Ryan's sword barehanded and reeled both him and the sword in for an attack. His great strength is shown during his fights with Raian holding off bladed attacks by force alone and even battling back his Bankai's spiritual attack. He had dispatched two of his opponents with presumably little effort, both of which were presumably Captain-level. Seireitou's strength is so immense that when he threw Raian, he was unable to recover due to the air pressure being too hard on his body. With a single downward chop, he was able to snap Mashiro's sword's blade in two. Seireitou was able to effortlessly cut through the sword and wrist of Kensei's Bankai. After overcoming his despair, Seireitou dramatically increased his overall physical prowess. This is shown by the fact that he can, through sheer force, completely overwhelm the Shunkō-enhanced Raian with no adverse effect to himself and also effortlessly destroy even a fully-powered Hado #90 spell. After training in the Murinne, Seireitou's strength allowed him to completely shrug off the force of a point-blank Getsuga Tenshō by Raian, while the latter was in Bankai. According to Saori Sumeragi, Seireitou has reached the perfect balance between speed and stamina with strength and durability, having conditioned his muscles through years of unique and unusual training methods. It is because of this that he boasts such unrealistic strength, without having a large-built body. The sheer magnitude of Seireitou's physical strength is displayed through countless moments in the series, most often implied by his tendency to always hold back during one-on-one fights; when the situation demands further strength, his blows are capable of tearing through the muscles of a Shinigami's body. Whenever handling most opponents, Seireitou elects to keep his fingers completely loose while engaging hand-to-hand combat. This allows him to utilize the sufficient level of strength necessary to handle the threat, per all of the abovementioned examples. It is basic knowledge among martial artists that it is important to keep one's fingers closed in order for the muscles running down through the arm all the way down to the fingertips are kept tight when delivering a hand strike or blocking an assault, so as to maximize the use of physical strength. In Seireitou's case, he keeps his fingers loose so as not to overdo the release of physical strength. However, when the opportunity should arise that greater strength is necessary, he may decide to tighten his fingers together. With any normal warrior, this wouldn't result in any major change, but because of his absolute levels of strength reigned in from centuries of martial arts training, pushing his physical body to predefined limits and beyond them, he can be thought of as nothing less than a true monster; an absolute force of nature. And therefore, the simple act of tightening his fingers together enhances the level of physical strength to an almost ridiculous precipice, as a mere swipe of his open hand with tightened fingers is enough to create a massive shockwave of reiatsu and brute force. Releasing his "reiryoku cuffs" causes Seireitou to unlock the true reserves of his physical strength, as the cuffs restrain him to using only about one-fourth of his actual might. When this occurs, the Sōzōshin's true strength is revealed, capable of unleashing strikes with such force, they decimate anything and everything within their line of range. Even without making direct contact, Seireitou was able to tear through Mūkade's Bankai structure with ease after releasing his reiryoku cuffs.


 * Tiězhǎng (铁掌, Chinese for "Iron Hand/Palm"): Not Yet Revealed
 * Tiěshān (鐵衫, Chinese for "Iron Shirt"): In reference to its very name, the Tiěshān is an exercise in which the practitioner conditions their body to become durable enough to resist an enemy's attack without succumbing to serious injury, if any at all. However, Seireitou has transcended the properties of his method of Tiěshān, to the point that it has become something as powerful and mysterious as the ancient martial arts themselves. He is like a piece of metal itself. Resilient and impenetrable, Seireitou's defensive technique is so great that it is almost impossible for any blade to cut through it nor to pierce it. He can withstand being struck by the well-executed swing of a sword without yielding any form of damage, even if he is dealt repeated attacks from all sides. Seireitou can go so far as to block the bladed assaults of his opponents with his bare hands, as if he were actually engaging them with a sword himself. His skin also takes on selective properties of metal, to the point that attacks composed of lightning are essentially useless against him and it also allows him to withstand heat to a far higher degree than even the strongest of spiritual beings would be capable of. This defense is often likened to the Arrancar's hierro, which compresses their reiatsu for the purpose of providing them with a hardened skin that'll protect them from enemy attack. However, the difference that exists in this technique is that Tiěshān itself has become a technique of mystery in and of itself. As high-density spirits, the Arrancar are known for having incredible physical strength that overwhelm Shinigami. In a straight physical fight, the Arrancar are the superior species because of their strength and dense spiritual power. Using his mastered reiatsu control and absolute self-control, allowing him to essentially treat his physical body and his reiatsu as a single entity, Seireitou can actually reel inward his spiritual pressure completely, achieving a strength and durability that reaches transcendent levels. Even an Arrancar's hierro pales in comparison to his body when under this condition. During this time, one finds it impossible to feel Seireitou's reiatsu for as great as it actually is, due to the fact that it has been completely reeled inward and condensed onto his physical body as a sort of armor. It is as if the very will of Seireitou as a martial artist is what protects him from the attacks of his foes. Combined with Kaerikotsu, it renders Seireitou nigh invulnerable to all methods of attack.

Genius-level Intellect: Despite his laid back attitude, Seireitou has repeatedly shown himself to be a perceptive and insightful man as well as being very detail oriented when it comes to fighting. He notices his opponent's mannerisms and discerns with ease the reasons behind those actions and the weaknesses and strengths of his opponents. Seireitou has an undeniable talent for thinking things well in advance as well, make decisive and accurate decisions quickly in battle, and able to perceive any situation at hand. He generally has shown himself to also be a crafty tactician from how easily he can deceive both allies and enemies. Seireitou has a great talent for analyzing and observing everything in his presence, allowing him to quickly understand a person's pattern of thinking to better manipulate them and seemingly always be aware of any danger. He also has very good insight on people, often knowing if they are troubled or hiding something; he sometimes even knows what a person is thinking, which seems to scare Minato. Seireitou has been shown to be very observant of his opponents' abilities and powers, even going as far as to use it against them. He is highly intelligent, possessing a genius-level intellect, and is capable of devising and executing strategies with incredible speed and precision. He has also shown to be a very perceptive and analytical man from how quickly he can analyze an opponent's power and attack patterns to ultimately make them useless against him. He is able to quickly determine a person's battle style after a single glance as well. After doing this, he can quickly place himself several moves ahead of his opponent and formulate the best counter-strategies. In addition, Seireitou has shown great ability in manipulating others to do his work for him. He easily outmaneuvers and tricks Mūkade on two instances in his fight with him. Seireitou is very resourceful, able to use a wide array of unorthodox tactics to accomplish his goal. The series repeatedly demonstrates Seireitou's mental acuity; ranging from his superb skill in playing chess, to being able to deduce complex facts from a very limited amount of facts. Beliar himself acknowledges Seireitou's intelligence surpasses his own immense intellect, who has constantly shown him. During battle, Seireitou often uses misinformation, disinformation and an analytical knowledge of a person's nature to help lull an opponent into a false sense of security and possibly make them carelessly over-confident. He also takes drastic strategies to often confuse and force the hand of his opponents. Seireitou tends to second-guess everything he is presented with, though often saying that he "went with his gut feeling" during those times. Whenever Seireitou gives percentages to indicate how much he suspects his chances of winning over an opponent, such as "five percent," in reality he means over ninety percent. Although Seireitou originally gives Mūkade a low percentage indicating how much he believes he'll lose to Mūkade, in reality Seireitou is "pretty certain" that he can beat him. Raian often pokes fun at this, telling Bella Pelear that "it is difficult to predict his actions, because the truth is, Seireitou's a liar."

Unrealistic Rate of Adaptation: Raian noted that one of Seireitou's most fearsome traits is his ability to adapt to an opponent(s) at a rate that is considered almost unrealistic. It is because of this that Seireitou almost never loses to the same opponent twice, if not once. Initially overwhelmed by the rate that Yukara Shihōin's power was increasing throughout their fight almost a thousand years ago, Jinsuke, who was observing the confrontation, noted that it appeared as if Seireitou's own capabilities were seemingly increasing at a rate surpassing that of Yukara's own, despite heavy injury, to the point of tipping the tide of the battle in his favor. Over the course of a thousand years, this tenacity reigned in through centuries of experience and wisdom has only become that much more frightening. Sōkudo commented that Seireitou was a monster in this regard, subsequently noting how his title of Shiroyasha was fitting.

True Hanshi Status: Renowned by many as a "teacher of teachers"...

Innate Abilities
Sparring Mode (スパーリングモード, Supāringu Mōdo): Martial art is based on deception. And one such as Seireitou, who is known for his unrivaled status in the martial arts, embodies this principle in both his mannerisms as well as his combat style. He is not inclined to demonstrate the true capabilities of his prowess, instead opting to use only the skills necessary for any particular situation. Thus, in the case of relatively inferior opponents, Seireitou lowers himself to fighting with the ability of someone who would be considered "slightly above the Captain class"; hence, the term sparring mode to indicate this level of severely reduced skill being utilized. In such a position, Seireitou uses the same abilities that a Shinigami Captain typically uses; in other words, an equal distribution of each of the four Zankensoki combat fields. He will face certain opponents using a medley of watered-down Hakuda, which relies primarily on pure brute strength as its source of power applied with precision bordering on perfection; focusing on a more physical and "mortal" means of fighting instead of using the various complex and transcendent skills and styles attained by one such as him that has achieved an absolutely unrivaled status in all of martial arts. Seireitou will also engage in Zanjutsu sword combat, as well as standard Kidō spells, the same way a Captain of the Gotei 13 would normally behave. While it is understood that Seireitou is a proponent of the ideal that rejects excessive force in conflict, the other reasoning behind the Sparring Mode is that it enables him to essentially avoid allowing others to examine and witness those thousands and thousands of martial arts that should not be seen nor experienced by the average challenger; it is not uncommon, after all, for a Grandmaster of a craft to maintain secrecy of his true capabilities. However, Seireitou has neither confirmed nor denied this assertion, though his attitude would suggest that this is indeed the case.

"The True Seireitou Kawahiru" (真の河昼精霊塔, Shin no Kawahiru Seireitou): While no name actually exists for this phase of combat, this is the term coined by Micythos when facing Seireitou in a one-on-one serious confrontation. It is when Seireitou abandoned the unnecessary fields of combat and devotes himself in battle entirely to his martial arts. In many cases, the transition from Sparring Mode into his "true state" is often displayed by the removal of his white haori jacket and sometimes the disarming of the swords fastened to his hip, casting them off as he also releases his spirit cuffs, thus releasing the full extent of his power and ability; in both physical and spiritual strength. The other combat fields are subsumed under Seireitou's Hakuda, serving as expansions and unique expressions of his unrivaled martial arts.

Legendary Hakuda Grandmaster
Among the four Yonkō, Seireitou is known as the respective master of Hakuda; the Shinigami system of hand-to-hand combat. Even among other Hakuda master-class Shinigami who have consistently shown extraordinary feats of strength and speed throughout the series, Seireitou still stands in a class of his own when it comes to hand-to-hand combat, defeating those kind of aforementioned opponents with strict ease. His unrivaled level of hand-to-hand skills has allowed him to truly be named a "Grandmaster" of this field. It has been said that Seireitou has taken the prowess of Hakuda to plateaus that have transcended the boundaries of previous theory and concept; becoming an embodiment of Hakuda that is unsurpassed in every and all martial arts. With respect to this, Seireitou has been named the one and only Legendary Master of Hakuda, therefore being the current holder of the title, "Greatest Martial Artist in the World" (世界最強の武道家, Sekai Saikyō no Butōka); a status sought after by many. Micythos, a powerful being in his own right, commented upon the silver-haired man's unrivaled and almost godlike prowess in the martial arts, saying that he is "not just a martial artist, but rather is martial arts itself — an absolute force of nature."

Three Stages of Hakuda Mastery Absolute Self-Control: At its core, the martial arts are a fighting force dependent upon the degree to which the master is capable of controlling their own body and self-existence. Therefore, a Grandmaster is one that has perfected control over themselves to a point that they become the architects of their own self. From their hair, nails, muscles, veins, and even their organs, all things are within the realm of their manipulation. Seireitou's body and mind are weapons that can not be taken; they can not be conquered except legitimately in battle against a foe that has somehow surpassed his own precipice of skill. It is not an exaggeration when calling Seireitou a true "force of nature", for his body and mind are instruments of his will; that is the extent to which his mastery over martial arts has reached. This is not a man that can be defeated simply by delivering a critical blow nor inflicting some kind of grievous wound. His control over the self is such that only a will capable of overcoming his own will can ever hope to truly beat him in a confrontation, and nothing less than that will suffice.

Stage of Shu — "Obeying Form"
General Hand-to-Hand Prowess: Known throughout the spiritual land as the Hakuda Grandmaster, he who has mastered all martial arts and the way of the self, Seireitou's Hakuda stands in a class all its own. It is considered something truly frightening when this man raises even a single finger with the intention to strike; as though a heathen had spouted blasphemy toward a sacred deity and those devout to said god shutter to think how their deity will retaliate. For whatever reason those of the martial arts world consider this man to be the honored leader over all practitioners and the precipice for all those that seek to master the hand-to-hand combat arts aim to reach, whether it be because of his knowledge or application, it is meaningless to debate. If a Master is one that has completely familiarized themselves with a craft to the point that they are permitted to turn those teachings into unique styles, then the true definition of a Grandmaster is one that no longer requires maintaining a style; every move is conducted with an innumerable amount of principles from thousands and thousands of different martial arts to such a degree that it is nothing short of perfection, all reigned in and condensed onto a way of being and a way of behavior, rather than a style of fighting. It is because of this that when Seireitou engages in Hakuda, his movements are no longer mere techniques, but methods of behavior themselves, that have reached such perfection that they can be considered a true zen of martial arts themselves. When one reaches this precipice of skill, the true stature of a Hakuda Grandmaster, the motive and intention of his movements reach the pinnacle of expression. The mere thrust of a single finger, normally meant to pierce a target, is akin to the strongest of spears when executed by Seireitou. Being struck by the edge of his hand, designed for normal practitioners to cause some form of specific damage that could possibly slash, is the same as being cleaved in twain by a master swordsman's blade. And the punch of this Grandmaster, if one were to consider a normal Master's punch to be like that of a thrown rock or boulder, is nothing less than the equivalent of a cannon smashing all opposition. Whether close up or at a distance, Seireitou's punch is a weapon of pure destruction. Eradication is to be expected when on the receiving end of this man's punch and one would be wise not to give this man a reason to curl up his hand. Similarly, this man's kick is like that of a tempest; blasting apart everything within its range and leaving naught but devastation in its wake. And when all of these methods of fighting are put together, Seireitou is nothing short of a force of nature in combat. A flurry of fists and a wave of kicks — it would be no different than attempting to conquer a maelstrom of razor hail or a tsunami capable of wiping out an entire community; leaving nothing but rubble in its wake. The force behind Seireitou's attacks carry strength enough that even the laws of spacetime bow to its might. A swing from his fist can cause distortions in the wake of its force. And accompanied by his, the force of Seireitou's attacks can easily be mistaken for Kidō blasts due to the appearance they can take; that is, of course, dependent on whether or not the foe is of great enough skill to even perceive the shape of such immensely fast and strong strikes. Not even the Captains of the dare to push this man to such a point, if simply out of fear for what this man is capable of inflicting upon their precious. Of course, this is merely in regards to the man's method of hardness, and in reality, perhaps the true danger lies not in his destructive force but rather the definition of softness that is prominent in the martial arts that emphasize the method of guidance and direction. There is a simple fact that should be known to all. And feared by all. If Seireitou is to lay a hand upon your body, the fight is over. Your defenses will be neutralized, your center of gravity compromised, and whether your fate is to be smashed apart, rendered asunder, or thrown away like a rag doll, one thing is clear; that unfortunate fool will never forget that this man's title is well-deserved, and that his skill is real, no matter how much of a mystery and a nightmare it may seem. Even as a small child, he was able easily defeat several adult Shinigami without even a scratch, despite having only began his training under Shōyō. This implies that, despite all the work he had put into his martial arts, he has always had a natural talent. Seireitou also seems to prefer applying a playful method of combat while holding back pure brute force, often being seen attacking opponents from aerial standpoints, but will commonly resort to stationary attacks that allow him to wipe out an opponent without warning. He has been shown to take down nearly fifty Onmitsukidō members with only Hakuda. He has been shown easily taking on the likes of Espada-level Arrancar as when he brutally defeated Xerxes Averian, whilst in the latter's Resurrección state, and is subsequently regarded by Almayo Vinas as highly dangerous. He can catch the attack of a Captain-level opponent with strict ease, making someone of that level look like a beginner when compared to his skill. Seireitou is also capable of delivering powerful blows that can smash through Espada-level hierro and block every single one of the multiple punches and kicks from several highly-skilled opponents. As of more current chapters, Seireitou seems to have foregone the need for a blade, relying solely on his martial art ability. He is capable of ending fights rather quickly, using only his expert timing and powerful arsenal of kicks and hand strikes. Saori Sumeragi has stated in many instances that Seireitou's hand-to-hand abilities make him appear as a "blade"; swift and agile, with no wasted movement, which makes it impossible for any opponent to find even the slightest of openings or instances of weakness in his martial art attacks. Raian, a fellow Yonkō, noted that Seireitou's level of hand-to-hand skill and capability makes fighting him at close range no different from suicide. Despite the seeming recklessness of his actions, Seireitou is able to remain focused enough to not lose his edge in battle, but rather enhance his already formidable prowess. Even against Noriaki Shiba, a senior member of the L'Obscurité, he was able to defeat and ultimately kill (albeit unintentionally) the warrior despite the grievous wounds he received from him, which is a testament to his skills. According to Raian, he does not depend on emotions such as anger but rather reveals these emotions in order to "put his opponent's heart off-guard and strike back without mercy". Raian often noted that Seireitou's most fearsome attribute in his Hakuda was neither power nor technique, but rather his unrivaled tenacity. This was best shown during his fight against Seimei Abe, allowing the latter to deliver a killing strike that would have normally annihilated anybody else and suffered several life-threatening blows, in order to set-up his positioning for a decisive strike.

Master of the Martial Arts: Seireitou models his Hakuda styles with martial arts that he had mastered during his training session and experiences throughout his long life. Among his more common uses of Taekkyeon and Taekwondo, his martial arts knowledge extends to the martial art form of Bāguàzhǎng, as well as a medley of other martial arts that he has mastered but are rarely seen in combat. Martial arts such as traditional Jujutsu and Karate, among many others, are no exception. In being the Grandmaster of Hakuda, Seireitou has mastered all of the hand-to-hand combat styles as well as all of martial arts in their entirety, though a majority of this knowledge is suppressed into his subconscious along with his Shiroyasha persona, due to the lethal nature that they all carry, keeping only a few hundred or so styles to his conscious awareness. Seireitou prides himself in being a martial artist of the "old" and the "new", having mastered long lost art styles that many have even barely heard of, let alone have seen or learned. His skill also carries over to the medical field as well, his intricate knowledge of pressure points and bone joints allows him to preform bone setting and acupuncture with minimal effort. It is stated by Noriaki Shiba that a master of Seireitou's level is capable of closing in the range of his attacks, and then extending the range at almost instantaneous instances. As such, he can effortlessly extend or minimize the range of his attacks, making it nigh impossible to catch him off-guard. Likewise, he is capable of shifting his fighting style between hard and soft styles almost instantly. Having been training Minato Kuramoto to better adapt to seemingly any situation, Seireitou has showed himself accustomed to countless fighting styles and techniques, stemming from basic but outlawed techniques to highly-advanced ones. This is shown by his capability of turning many seemingly basic techniques into fatal one-shot attacks, such as when he used Front Kick, it was able to completely crush the ground beneath him, as well as generate a massive shockwave of pure force in the direction of his opponent, which shocked Minato greatly. Martial arts is the act of mastering the control of one's body, and Seireitou's control over his body is so great that he is capable of twisting his body and bending his legs in ways that would surprise many Hakuda martial artists, among even Captain-class Shinigami. Likewise, acrobatics are not a difficult thing for him to accomplish, making both of his students doubt he is even a real person, or even maintains a solid form, whenever he demonstrates these capabilities. He is able to effortlessly tighten his muscles to make his body as tough as steel while allowing himself to remain relaxed enough to breathe and move his limbs and body effortlessly, doing so at speeds so great that it can be accomplished right at the instant an opponent's attack nears his person. In addition to this reserve of never-ending knowledge of techniques, due to his years of experience, he can copy any move of a master-class fighter, no matter how unique it is to the opponent, which has helped in the development of his one hundred and eight secret techniques.

Generally his main martial arts, Seireitou teaches this art at the Kawahiru Dojang; being a world-reknowned Grandmaster in the World of the Living and the Reikai in this particular martial art. While bearing two different names, they are essentially the same martial art. Taekkyeon is the predecessor to Taekwondo, and specializes in circular kicks. Utilizing his brand of "off-the-ground" fighting, he normally uses these circular kicks in addition to his immediate changes in momentum in order to deal surprise attacks added with an immense burst of strength and speed that supplement the already massive force generated by his own muscles. One of the most impressive feats of his skill is that he was able to break through sekki-seki stone with very little effort. In essence, Seireitou's kicks are capable of breaking bones and destroying joints effortlessly, tearing through substances such as concrete and steel, and can be used to block the swing of an opponent's sword, subsequently knocking the blade out of their hands by aiming for their grasp or their wrist. In Taekwondo, kicks and strikes are generally more straight-forward, and Seireitou's ability to switch from Taekkyeon to Taekwondo is a direct result of his hard-to-soft and soft-to-hard capabilities, as they are essentially two sides of the same respective proverbial coin. Both styles emphasize the uses of kicks, and because of this, Seireitou can also use his legs to block incoming attacks, only to counter with lethal pin-point attacks. The most primitive form of Taekwondo, which preceeds even Taekkyeon, is Seireitou's secret Hakuda weapon, used only when he is pushed to life-threatening extremes. Being such an old art style, the exact nature of Subak is unknown, as even among other Taekwondo masters (of both Shinigami and Human) have scarcely heard the term, let alone aware of any of its techniques. Seireitou tends to only practice the style when he is alone, usually at night, and doesn't appear interested in passing on its secrets to Minato. He made it clear, however, that Subak is a style that is not suitable for "sparring", implying that it is meant to kill. Seireitou has revealed that Subak, like Taekwondo, contains many types of strikes and kicks, but exists a particular way unique to Subak that proves to be extremely effective against a target's body structure. Even against muscles that are honed to almost god-like proportions, prompting them to be physically immune to strikes, there are techniques that allow the muscles to be "side-shaken", dealing damage that is great enough to rip the muscles in question apart effortlessly.

Utilized more as a defensive style of his, Seireitou holds a grand amount of Bāguàzhǎng mastery. Dealing in the strict use of free-jointed circular movements, the steps of Bāguàzhǎng are often very unpredictable, and in when used by Seireitou, make it near impossible for an opponent to land a strike on him. In Bāguàzhǎng, footwork is key and when used to its highest levels, can allow the user to enter into an opponent's "blindspot" (殺し, Korui), something that is very rare for any hand-to-hand combatant to develop. Seireitou has demonstrated his mastery of this ability to Minato by moving through a large crowd of people and not once was his presence registered by a single person. Seireitou uses the footwork of Bāguàzhǎng to generally set up for a Taekwondo kick or even a Jujutsu throw. Bāguàzhǎng also deals in internal damage to an opponent, via the pressure point system of the body. Seireitou will also use the hand techniques of the martial art to deal internal damage to opponents through this method, allowing him to damage the organs of an opponent's body, while altering their spiritual energy flow; for better or for worse, depending on the situation. In one instance, he was able to strike the wrist pressure points where spiritual energy is focused in every Shinigami, sealing it which resulted in the internal explosion of the victim. As mentioned before, Seireitou uses these capabilities for healing purposes as well; focusing on acupuncture primarily. Circular movements also apply to the user's arms, in which a master-class martial artist such as Seireitou can control the radius of his reach with these circular techniques, which combined with his self-created Seijūken technique, allows him to instantly block, redirect, and counter an opponent's attack, all within the time span of a single breath. The speed at which he can move his arms is also incredible, to the point that it sometimes gives off the illusion of him possessing multiple limbs. These circular techniques are often combined with Taekwondo's linear-based kicks and strikes, making for an nigh invincible and effective combination. Bāguàzhǎng, in itself, is considered to be the "Kidō Martial Art" by those who see it in action and observe its effects. Seireitou has often stated that the very essence of martial arts is to examine, understand, and manipulate the "flow" of energy between opponents and between the fighter and their environment. Essentially, that energy is always in movement and is moving both around and through living beings as well as inanimate objects and surroundings. When a fighter is able to translate this understanding through their martial arts, then they have truly become masters. However, for most, it is impossible to actually control this "flow" of energy and that most internal martial arts work to exploit the weaknesses of an opponent's flow. However, through Bāguàzhǎng, Seireitou is capable of completely altering and affecting (possibly even disrupting) the flow of energy in the air around him through the use of his Hakuda. By aiming for key meridians of the opponent's body, via palm thrusts, Seireitou can alter the course of energy flowing around the opponent and through the opponent, essentially weakening their subsequent counterattacks or chances of continuing the fight. By doing so, the effects that can occur can end up weakening the joints (affecting flexibility) or causing a disruption in their internal and external energy patterns (such an action can cause one's spiritual energy to surrender to a stronger, more resolute one, making an opponent's attacks unable to cause damage, and even disrupt their ability to gather spiritual energy, such as the case of Quincy). Many other effects are possible based on how the flow of energy is altered, dealing in various results.

Exclusively a soft-type martial art, Jujutsu is an art that specializes in joint holds, throws, and locks. In addition, it is a method of close combat in which one is trained to defeat an armed opponent in which one uses no weapon. The techniques of Jujutsu allow Seireitou, when one considers his master-level ability, to effortlessly manipulate the joints of a target's bones. This can be used to either break an opponent's joints, thus dislocating certain joints such as the shoulders and knees, at close range. This is demonstrated by a "bad habit" he has of dislocating an opponent's wrist whether they place their hands on him, often warning Minato to never sneak up behind him and tap his shoulder. However, even when this happens, he can effortlessly realign the joints with a simple flick of his expert technique. In addition to this, Seireitou mentioned to Minato that there exists a Jujutsu technique that allows one to throw their opponent without laying a hand on them; a claim which was considered far-fetched by the former until Seireitou revealed the attack's authenticity during a fight with Jihan Kanda. Unlike the linear kicks of Taekwondo or the circular footwork of Bāguàzhǎng, Seireitou's Jujutsu seems to be on a level of its own. Despite being a soft-type martial art, the methods of which Seireitou manipulates (usually which results in joint dislocation) the bone joints can be seen as brutal while having a swift elegance. Even what may appear as a gentle tap to an opponent's ankle covers up the true incident of the bone snapping in two because of a forceful attempt to dislocate the ankle joint. Regardless, his technique is flawless, and can even predict the exact location at which he breaks the joint. Circular motion of the arms is often used to wrap the arm around an opponent's limb in order to subsequently break it or to throw the opponent. However, it is rare for a Jujutsu master like Seireitou to attack first using these techniques. In fact, Seireitou utilizes his Jujutsu abilities as a counter-attack to an opponent's own strikes, despite his rare tendency of violent dislocation. These traits of his Jujutsu make allowing Seireitou to grab hold of a limb a hopeless situation, with Raian commenting that the fight was over the moment Seireitou took hold of Kizaru Mōji's arm. However, this is merely the physical level of Jujutsu. Its true purpose in manipulating the direction of a target's force is redefined in many ways when in the hands of a Grandmaster. Whether Seireitou's limbs are being utilized or not is a meaningless gesture, it is the pure expression of will that makes this art form so efficienct at its transcendant level. The air and winds around Seireitou become tools, as if he were wielding them as weapons, but it isn't in any way limited. Even the oceans and seas that may surround him, the rocky terrains, and the heat itself that illuminates the plains by the Sun, became tools that act in accordance with their director. This is the truest expression of Jujutsu, the "gentle technique", as its Grandmaster merely alters its intended purpose and direction onto whatever form he wishes. Its prowess is limited solely by what resources are made available to Seireitou, though it is foolish to assume he will ever run out of weapons, as the entire world is his weapon. Being a sub-discipline of Jujutsu, Seireitou has shown himself to be a true master of the Torite, or "Catching Hand" (捕手) technique. Appropiately named "catching hand", the Torite is a technique that allows for a martial arts master to deflect and catch actual weapons. With a skill level like Seireitou, the Torite becomes great to catch the blade of even most Zanjutsu masters. It was professed by Seireitou that only Raian Getsueikirite, or those at the latter's skill level, can actually utilize sword techniques that are effective enough to make Torite useless. The idea of Torite, or rather his use of it, works according to the method at which Seireitou uses his hand or fingers to catch onto an opponent's sword. Using a single finger to block the strike of a sword is one of his favorite uses of Torite which is similar to the feat accomplished by Sōsuke Aizen, though it far outclasses Aizen's version in that it does not use raw strength whatsoever. In reality, Seireitou allows his finger to act like "a rock in the river", allowing energy to circle around it without any harm befalling it. By his immense comprehension of energy and force flow, Seireitou causes the entire force behind the opponent's sword attack to essentially move around his finger and escape from the opposite end in the very miniscule instant that his finger and the opponent's blade come into contact; that very instant. In this sense, at the very nanosecond that his finger and the blade make contact, the force behind the blow has completely abandoned the sword strike, meaning it has returned to a state of rest, making it child's play for a man of Seireitou's strength to hold the blade's sharp edge with his finger. No matter how much force may be behind the strike, Seireitou will be able to stop it with a single finger using his unique Torite method. Therefore, the only conceivable possibility to actually strike Seireitou with a sword strike comes down to pure skill, not strength nor motion of the swing. However, Seireitou comments that the more strength is behind the sword swing, the easier it is for his Torite to deflect the attack effortlessly, even if the swordsmen in question is of master-class skill. Therefore, attemting to strike down Seireitou with a single sword technique is virtually impossible and must require a combination of masterful timing and master-class skill level in order to land a contact blow. Seireitou has shown himself capable of blocking hyper-speed sword strikes, ranging from slashes to pierces, using only his one-finger Torite technique. However, when applying his neijing mastery to his Torite sword catching techniques, he utilizes a full-hand catch of the blade. Once he does this, the force of the sword slash does not "circle" around Seireitou's hand and escape from the sword but rather it reverberates at the point of impact. It is likened to Seireitou's Kaerikotsu defensive technique in that neijing energy then storms the blade from the spot where Seireitou stopped the sword slash, causing the entire sword to shatter into small pieces of metal.

Martial Art Conditioning: In all of Hakuda, before one may learn techniques, one must develop a foundation within their own bodies. Through a constant repetition of these, one may gain a degree of strength, durability, and internal balance; among other traits. Before long, it becomes routine for them to engage in these exercises. However, for those that have achieved a superior level of proficiency in the martial arts, such as Seireitou whom has ascended to the precipice of Grandmaster, these exercises become aspects of the warrior's very nature. They become something beyond the normal. Instead of becoming a routine, they actually become the strengths of the martial artist; standing to be powers of their own accord that the martial artist uses to access some form of benefit.

Development of Stances: Unlike the undeveloped form of Hakuda, if it may still be called such, used by low-ranking Shinigami that deal in simply attacking an opponent using the arm or leg, those who rightfully deserve the title of "Grandmaster" within the field of Hakuda emphasize the use and development of the stance. A stance is essentially the art of distribution, foot orientation and body positions adopted when attacking, defending, advancing or retreating. While most of his stances are strange and unique, not seen often by other Hakuda masters, he doesn't appear to have names for all of them.
 * Tenchi Jōge (天地球逆様, "Heaven Earth Upside Down") is the Nakanisentō stance of "offensive annihilation". By positioning one arm near the chest and stomach, and the other at near eye-level, both palms kept open, the user compresses their spiritual pressure completely, in order to make each of their attacks result in fatal damage. While not seen being used by him, Seireitou is credited with the creation of this Hakuda stance, and eventually passed its teachings on to both his son and Minato Kuramoto. It is through this stance that he initiates his Jujutsu attack usually. It is common for Seireitou to enter this stance prior to using Sokotsu against an opponent.


 * Maeba (前翼, "Front of the Wing") is the Sotosentō stance of "absolute defense". Both arms are placed symmetrically in front of the user's body, the palms flattened and held upwards, as if being centered to hold something. What makes it an "absolute defense" is unknown, as Seireitou was interrupted before being able to show its capabilities by the untimely appearance of Kyebaek Tae. Kamui is the one credited with the creation of this stance, and it is presumed Kamui taught Seireitou this back during the duo's time in the Seijin Council. When used against Hōsen Kuramoto, its true nature is revealed. Combined with the neijing concept, Seireitou uses his open hands to divert away the force of an opponent's physical attacks. By twisting his arms inward and outward, the subsequent motion causes his open palms to follow with that and causes all direct enemy attack forces to be diverted off into various directions. In this sense, Seireitou does not meet power with power but rather expends no energy at all, merely causing an opponent's strikes to bounce away and miss entirely, making them feel as though they are succeeding in tiring out Seireitou, but rather they are wasting their own energy. In this sense, Maeba is the ultimate defensive stance against another master of Hakuda.

Immense Repertoire of Techniques: While Seireitou prides himself in acting under the principle of the "style of no style", carrying himself as a person with uncharacteristic characteristics, he is known to possess a vast arsenal of Hakuda techniques that he has either collected from other sources or invented himself, which fall under specific categories; not simply as offensive or defensive. Whether they be hard-type or soft-type, many of them being broad in their strength and application, ranging from the basic to the advanced, Seireitou's level of skill with each of them is enough to consider each and every one of them lethal; so far so that each offensive technique could quite possibly end the life of almost any equal or lower strength foe should it connect directly, while his defensive techniques are considered nigh impenetrable, creating a space around his being that makes all aggressive attempts on his person ineffective. He has claimed to Minato Kuramoto that the primary goal in all of martial arts, and subsequently in Hakuda itself, is the protection of oneself and their allies; in other words, defense. In specific regards to the aforementioned, he has made it clear that he has had a hand in formulating and mastering several thousand different defensive techniques that all find their origins in one of the countless martial arts he has mastered. While most of Seireitou's Hakuda techniques fall under the various unique styles he employs (aside from his neijing techniques), many of his Hakuda techniques are commonplace, being techniques that fall under one of the many martial arts that he had mastered in the process of becoming a Grandmaster. It is noteworthy that many of the techniques he employs, more so the basic ones, are generally nameless or are simply not named by Seireitou when being used. In addition to the standard techniques he employs, Seireitou's level of mastery and his years upon years of training has resulted in the formation of several hundred different techniques unique Hakuda techniques only to him and him alone. While many of them find themselves being derived from techniques learnt prior by Seireitou, nearly every single one of them finds some form of connection to one (or possibly a combination) of the numerous martial arts he wields mastery in. Additionally, there are also techniques within his repertoire that normally act in setting up for Seireitou's plan of action when it comes to certain opponents. In this sense, they are likened to the pieces of a chess game, as certain techniques help to set the stage for a finishing move. Despite this, however, they can work in individual manners, ending an altercation with a single technique. Many of these techniques also happen to serve healing purposes, allowing for such things as bone-setting and other associated treatments. It appears many of these are rather unique and strange in their operations. In fact, it has been said that many of the techniques appear to be nothing even related to Hakuda. Those that were invented by Seireitou were created as a result of his unusual methods of martial arts training. Saori has hinted that some of them have to do with anatomy manipulation of his being.


 * Kyōsae Hakotsu (鏡遮破骨, "Mirror Obstruction Destroying Bone"): Built upon the principles of kuzushi, this is a secret defensive technique created by Seireitou in order to originally combat Genryūsai Shigekuni Yamamoto's Ikkotsu technique, but was later perfected to deal with any sort of similar attack. After entering an offensive stance, which serves the additional purpose of misleading the opponent to the defensive nature of the technique, once the Ikkotsu was to reach within range of his body, Seireitou would swerve his arm around the arm from the outside and turn it inwards from below, swiftly bringing the knifehand upwards and locking the arm of the opponent. However, the purpose of doing so is to exploit the projection of force that comes with Ikkotsu, by intercepting the movement of force and essentially "trapping" it inside the arm of the opponent so that it never reaches Seireitou himself. If the opponent does not realize that the projection of force has been obstructed, it is possible that the force of their Ikkotsu technique, or any other attack of similar behavior, will end up reverberating back throughout their arm and even their body, causing immense internal damage that can outright destroy the muscles of their arm and even cause other significant injuries in the process. Seireitou later developed a two-armed variation in order to deal with Yamamoto's Sōkotsu, though he had never gotten a chance to utilize it in actual combat.


 * Taketonbo (竹蜻蛉, "Bamboo Dragonfly"): With a swift motion of the hand, the practitioner essentially throws their target, ideally flipping them onto their back. However, it can be taken a step further, which allows the user to violently thrash the victim before finally allowing them to fall to the ground, dealing far more injuries and possibly leading to them having the wind knocked out of them. While the most basic use of this technique requires the hand of the user to grab at the target at lightning speeds in order to engage the throw, Seireitou further refined this technique to a level in which it does not require any physical contact whatsoever. Simply coming close to the silver-haired man's body is all that prompts the Taketonbo, allowing Seireitou to quickly neutralize an opponent's physical motion and influence their entire stance, which is the main focus of grappling techniques, subsequently causing him to throw the victim and ultimately flip them. If he so wishes, he can even repeatedly toss and throw his opponents, without ever lifting a single finger. Opponents that foolishly attempt to reach out and strike at Seireitou will find their center of balance quickly compromised, their equilibrium disrupted, and their entire beings thrown down; all in the same instant as they attempt to somehow understand what had just transpired.


 * Tesshō (鉄掌, "Iron Palm"): Designed originally as a means of dispatching Hollows in situations where a Shinigami has been rendered unarmed, the Tesshō is an open palm strike that demands the devotion of the practitioner's entire body to be focused into the small region of the palm's center, delivering a powerful strike forward that can completely demolish a Hollow's mask and subsequently their entire head, effectively killing them with a single blow. It is a technique that doesn't possess any innate trickery or clever maneuver, but rather, it is as it claims to be; a strike to conquer all that lay before it. With Seireitou's superior physical strength, the Tesshō is powerful enough, even in his restricted form, to impress the very shape of Seireitou's entire hand onto any surface that may be within the range of the attack's pressure. And with it, all targets within the scope of his hand are crushed along with it, smashed into the surface or sent flying through the air; their bones and muscles forced to the breaking point and horribly damaged from just attempting to resist the force of the strike. However, many have noted a distinct difference between Seireitou's common use Tesshō and the Tesshō used naturally by the Shinigami; the main difference being that when he uses it against normal enemies, he keeps his fingers spread out while preforming Tesshō. Doing so causes the energy to become far more spread out instead of concentrated, but even then, the destructive capabilities of his Tesshō are still to be feared. He can choose to close the gap between individual fingers and still cause incredible changes in the strength behind the technique. Just by keeping the index finger and middle finger alone together, the Tesshō is nearly double the power. But this is nothing but the beginning. Like the reach of Buddha's palm which is said to be as large as the mountains themselves, used to imprison the Monkey King, Seireitou's Tesshō is a thing of legend once it is used at the peak of his power, though few have ever had the honor of witnessing it.

Nukite (貫手, literally "Crossbeam Hand"): Originally belonging to the discipline of Karate, having later been adopted by many other martial arts, the Nukite is an open-hand strike that makes use of the fighter's fingers as a means of combat. Essentially, it is a strike that operates by an incrementally decreasing number of fingers in the form of knife hands in which each strike with its particular number of fingers has a specific purpose. Having been credited with its invention and integration into Karate's original chinese form, "Te", Seireitou is famous throughout Soul Society for his Nukite technique, which was said to have slain thousands of Hollow and Quincy, among others, in his time. Nukite has been often described as the tip of a swordmaster's blade in Seireitou's hands, operating with the same idea as it can cut through nearly anything with incredible precision and accuracy. However, its power and aim are dependent on the number of fingers at which Seireitou uses to preform the technique. In the hands of a Grandmaster, the Nukite ceases to simply exist as a technique and becomes its own fighting style altogether. Nukite makes the act of Seireitou using a weapon meaningless due to how simply amazingly powerful its cutting ability is as it can tear apart even iron and steel if it should lay before him as a target. The idea behind Nukite is a technique that can void all defenses that lay before the strike. However, this is merely the tip of the iceberg. It is a technique that can ideally break through any technique that should oppose it; whether it be an offensive opponent or a defensive target in nature, a "true" Nukite should be able to destroy it no matter the obstacle. The most famous use of the Nukite in all of Soul Society's history was when Seireitou, during his tenure as Captain, had used it with both hands to demolish Genryūsai Shigekuni Yamamoto's Sōkotsu strike; a collision which led to a massive explosion within Seireitei's walls and severely damaged one of the Captain-Commander's arms in the process, whilst leaving the silver-haired Captain unfazed in the aftermath. It can be said that the Nukite, or rather Seireitou's Nukite, surpasses the neijing techniques Ikkotsu and Sōkotsu in theory. The alteration of numbers in the fingers each Nukite technique uses will often correlation with a specific degree of destruction and accuracy that Seireitou intends to inflict upon the target. With each finger added to the Nukite, the attack focuses more on bludgeoning force as a means of tearing through the opposition while the technique with fewer fingers focuses more heavily on penetration and cutting. In addition to the difference in numbers of fingers, the original Nukite that Seireitou invented has almost thousands of different advanced techniques that utilize the former attack's principles as a base.

 * Shungaryū (瞬我流, "Instant Self-Taught Style"; literally "self-taught on impulse/rebound"): Something that can be neither taught nor learned, only developed through centuries of experience and training, the Shungaryū is a martial art invented by Seireitou himself and serves as one of his most preferred methods of combat. As the name implies, it is a variation of "garyū" (我流, meaning "self-taught"), referring to a style of martial arts unique to an individual as it is something that they teach themselves rather than being formally trained by an instructor; crafted through a means of specifically accentuating that particular individual's strengths while simultaneously serving as a response to perceived potential threats one may face down the road. The Shungaryū is a step beyond this principle, as it is a method which is founded upon observing the opponent's technique and instantaneously developing a counter technique that will either neutralize or overwhelm the former. Such a thing is only possible by somebody of Seireitou's skill level as it demands the Shungaryū user to be capable of discerning the nature of a threat and immediately design countermeasures to fend it off, typically in the form of a new technique that is completely thought up on the spot.

"Penetrating Fist" (☴): Old as the mythology of Japan itself, the style of the Penetrating Fist can be traced back through human history to an ancient martial art form aptly known as Koppō (骨法, literally "Bone-Breaking"; also translated as "method of using the skeletal structure") which had branched off into multiple obscure modern forms while also becoming prominent in many of the well-known art forms. Many whom are aware of Koppō's existence note that it serves as the "backbone" of all martial arts, due to body posture and structure being all developed from these teachings. However, the Penetrating Fist itself, Koppō's own ancestor, can be traced back even further; prompting one to discover that its lore goes back far beyond mere mortal lineage and ascends onto the realm of deities. In its most simple terms of understanding, the Penetrating Fist is a martial art that focuses on attacking the core of the threat. On a physical level, this can be understood as attacking the target's skeletal and nerve systems, rendering their body useless and inert. The principles of the Penetrating Fist lie in pressuring and eventually destroying the framework that holds any structure together. All things have a frame which allows it to exist, despite if they should be physical or mental or even spiritual. The Penetrating Fist is a martial art method that will destroy it outright no matter what it actually is so long as the martial artist can utilize its principles successfully. The actual movements and techniques of the Penetrating Fist are never superfluous; rather simplistic and straightforward as they seek to finish the confrontation as quick and efficiently as possible. Penetrating Fist maximizes damage, pain, and stress, obliterating the target's proverbial skeleton while preserving the user's own power and stamina. Ideally, one eventually views the opponent as nothing more than a framework with points that must be struck in order for its entire structure to be rent asunder. Miyamoto Musashi noted it best when he stated that all things collapse, no matter what they are, given that one manages to disrupt the rhythm that maintains their hold. However, the Penetrating Fist is far from something as gentle as mere "disruption", as its goal is the total destruction of the framework and subsequently the structure itself. It is impossible to simply preform the Penetrating Fist technique and hope to achieve the desired result. Penetrating Fist is a style that requires an advanced discipline and spiritual refinement, which combined will allow a user to learn to strike an opponent's internal framework without needing to expend actual force onto their body itself. However, the true strength of this martial art is not limited to the physical. Through mastery of the Penetrating Fist, one is capable of implementing its philosophy onto the realm of the mental and spiritual. However, it is only through a master of Seireitou's status that such a realization is ever brought to its highest degree and application; to the point that it has transformed and transcended into a weapon of pure destruction that exists as an unstoppable force of nature in its own right. Being the Penetrating Fist's "rightful grandmaster", due to the aforementioned feats, Seireitou can apply the philosophy of the martial art in all realms. Without even needing to analyze a target's body, due to having an incredible unrivaled knowledge of both physical and spiritual bodies of various beings, Seireitou can instantaneously crush an opponent's bones to absolute dust, rendering their limbs moot as they collapse into a pool of their blood and cartilage without causing any actual harm to their outer body, no longer possessing any frame to hold everything together. He can even deliver strikes that can destroy the spirit energy flow points, such as the Saketsu and Hakusui, sealing away the power of a Shinigami or Arrancar. Even the Zanpakutō themselves shatter before Seireitou's Koppō, for even blades and weapons possess a frame which can be exploited and then attacked. Warriors are unable to actually enhance their bones' durability because it simply isn't something that can be improved through any method of training, making it quite impossible to actually defend against Seireitou's unrivaled and masterful Penetrating Fist. It is highly suggested one not tempt fate by trying to resist the Penetrating Fist's physical assaults as it is quite literally suicide to do so. Attacks themselves can be broken apart through the Penetrating Fist, whether they be physical or spiritual techniques, as even such things have a frame which allow them to exist in a refined form. It reduces everything onto total chaos, causing everything struck by its techniques to lose its order. But as it was aforementioned, it is not limited to physical feats. Even illusions are structures; mental constructs designed to alternate and redirect the mind of its intended target(s). His Koppō can eliminate illusions by attacking this framework which allows it to function, causing it to be dispersed and effectively diminished. The true danger is that Seireitou can actually use the Penetrating Fist to produce illusions and hypnosis onto the target by striking their "mental framework" through his will alone. He can impose the same effects as an illusionary technique though doing so will unavoidably result in the total destruction of the target's mind; the Penetrating Fist actually "mind crushing" the victim. However, this is something that can be more properly trained to defend against in comparison to the Penetrating Fist's physical applications due to many warriors being able to actually strengthen the frames of their mind through mental fortitude such as meditation; the Jinzen being a prime example. Souls themselves can be broken and torn apart through the Penetrating Fist in a similar manner as a mind can be. Those souls weakened by doubt and lacking resolve can not hope to stand against Serieitou. It is because of how destructive and lethal Seireitou's Penetrating Fist can be that he refuses to teach any pupil its secrets. Should it ever fall into the wrong hands, it could mean disastrous ends for thousands of innocents.


 * Ikkotsu (一骨, "Single Bone"): The amalgamation of every "fist" from every "martial art", condensed together and refined into a single punch that can take the form of thousands depending on the master who wields the fist, Ikkotsu is the Hakuda Grandmaster's weapon of choice. Ideally the simplistic yet one of the most devastating of projection-type techniques, for one who has mastered the concept, the Ikkotsu is a one-handed punch that is meant to connect with a specific point on the designated target. It is among Seireitou's most commonly used Hakuda techniques when wishing to end fights in an instant. Having trained under all of the chinese martial arts, Seireitou has attained an almost unrivaled understanding of the nèijìng (內勁, "internal exercises") concept. Because of this, he has attained knowledge of several powerful techniques that apply the Penetrating Fist concept in their usage, in addition to having developed many of his own. The Penetrating Fist does not involve using physical force to deal damage, but rather uses an internal energy that is concealed within external explosive force in order to deliver strikes that can shake up an opponent's internal organs and muscles. In essence, at the point of contact of the external strike, the internal energy is focused to fan out from that point and spreads outwards into the target. The result is not based upon the damage that the initial strike would normally cause on its own, but rather that the target is demolished into minuscule pieces due to the vibration of the internal energy fanning out from that external strike. This particular form of internal energy is considered "neijing energy", which is generally developed through ki being directed by one's willpower, and unlike physical force which can decrease with age due to muscles deteriorating over time, neijing energy proves itself to continue becoming stronger as the years pass. In Seireitou's case, the combination of the initial external strike and the fanning of the neijing force makes these particular techniques life-threatening to almost any sort of opponent should any one of them make direct contact, tearing an opponent's body apart and rendering them a mess of blood. In order to prevent this, in most cases due to following the ideals of, Seireitou abandons physical force in the initial execution of the neijing technique, utilizing only the internal energy that vibrates through the opponent's body in order to devastate the body of the target without causing their body to violently tear apart. Against Blut Vene, especially, the use of even a weakened version of a neijing attack is suicidal, as being struck by one whilst using the defensive Blut will cause every single one of said user's blood vessels to rupture violently. Ikkotsu, therefore, is the expression of "penetration" through the use of a single fist. At the point of contact with a target, Ikkotsu channels the neijing internal force through the fist, causing it to vibrate all throughout the body of the target being struck, causing massive destruction in their internal organs and subsequent organ systems. When diluted nearly ten times of its full strength, Seireitou's Ikkotsu has the strength to deal a decisive blow to an opponent of nearly equal or lesser power, causing all organs within the point of contact to rupture indefinitely. An Ikkotsu of similar power, dealt to a direct location such as the head or the arm, would cause the entire limb to collapse onto bloody pieces. It is for this reason that Seireitou never uses Ikkotsu beyond a dilution of one-fifth of its full power, as any more force applied to the punch would cause an instant kill of nearly any opponent if it were to connect. Full power Ikkotsu entails Seireitou combining both the neijing internal force and the external force of his own massive reserves of physical strength, uniting together to generate a punch of such force that decimates anything and everything that stands before it. Because of the technique's simplistic workings, Seireitou can cause the neijing energy that fans out from the Ikkotsu punch to behave in various ways, for a medley of different effects. Once the punch has been thrust outwards, the neijing force can instead be made to compress tightly, forming a drill-like punch that can punch through targets from a considerable distance away. Doing such a feat means that everything within that narrow space would be crushed. Against this drill form of Ikkotsu, should it connect with the target physically, would tear through everything within the frontal scope of Seireitou's fist. Even from roughly two kilometers away, it can punch a hole straight through an opponent's body when used in its weakened form. In a more defensive manner, Ikkotsu's force can be made to vibrate immediately outwards in the air from the fist once it has been thrust, forming a perfectly uniform and circular shield of neijing force that can serve as a powerful defense to most forms of offensive attacks. It can be used to dispel such attacks like Getsuga Tenshō with a single use of Ikkotsu. Seireitou is able to actually cause the space around him to distort by sheer brute force when swinging his arm rather than thrusting it forward, causing a wave of pure force to crash into the intended target; regardless of its proximity to Seireitou, as even a target from a significant distance can be struck down and rendered apart. The air bends and snaps to accommodate this distortion of space, crushing apart the target and victim without prejudice. Because of the nature of this technique, normal spiritual attacks are rendered useless against it, as the distortion of spacetime and the air bending around to fill in the vacuum make it difficult for anything to pass through it unscathed, much less at all. In addition, because the hand strike works in this manner, it can even bypass normal defenses. While it can be blocked and resisted to some degree, it is nigh impossible to actually defend against the attack in its entirety, as even a fraction will manage to find its way through. Because of Ikkotsu's very easily altered power, it is easily one of Seireitou's most versatile Hakuda techniques and equally devastating in combat. Seireitou is also capable of literally cracking the space around himself by striking at the "backbone" of the dimensional space around him, which allows for several results to occur. It literally cracks dimensional space itself and can send devastating shock waves through the air in the direction it is facing. These shock waves are able to pass through and damage almost any substance, literally tearing it apart. Because of its enormous offensive power and quick speed, this attack can also double as a seemingly impenetrable defense, able to destroy or disrupt any attack before it hits Seireitou. He was also able to form a barrier of sorts, the vibrations of which protected him from being struck by even the form of a mental attack, as vibrations can disrupt brainwaves; this could provide an easy method of stopping any form of prolonged hypnosis.


 * Sōkotsu (双骨, "Double Bone"): Having been invented as the two-fisted variation of the Ikkotsu, the Sōkotsu had initially been considered to be simply a twin usage of the base Ikkotsu technique itself. Genryūsai Shigekuni Yamamoto had used this primitive method when he destroyed Wonderweiss Margela, which despite its considered inferiority, was enough to completely eradicate the latter in a single move despite the Arrancar's high-level hierro defense. However, according to Seireitou, Yamamoto had used merely a small fragment of Sōkotsu's true power in that aforementioned fight. The premise of Seireitou's Sōkotsu involves allowing the neijing internal force to leave both of the fists upon contact with the target, like two rivers converging into a structure and overwhelming it, which at a basic understanding of the technique would lead one to believe it would merely double the effect of a normal one-handed Ikkotsu. However, this is incorrect. The secret behind Seireitou's Sōkotsu is that once the two fists make contact and release the internal force, a collision of the two waves of neijing energy occurs, which when used by someone who is lacking in neijing mastery, would cause the two waves to collapse upon each other and weaken their Sōkotsu in the overall view. In the grand scheme of things, that particular Sōkotsu would be only slightly stronger than a master-level Ikkotsu. Seireitou boasts that his Sōkotsu has been perfected, in that when he preforms the technique, the opposing waves of neijing released from both fists do not interfere and weaken one another, but instead bounce off of eachother, causing both individual neijing forces to vibrate several additional times with each collision while within the body of the target, spreading out in the target's body in a very chaotic manner as opposed to the uniform spreading of the Ikkotsu technique which can lead to an even more disastrous result. The randomized movement of the neijing force waves make it so everything connected to the point of contact will be decimated onto utter ruin, seeking to assure that any target struck by the Sōkotsu are completely and thoroughly destroyed. The result of these collisions leads to the neijing forces actually empowering eachother, trading energy between eachother as they seek to decimate the opponent. Seireitou considers his Sōkotsu to be cruel in that should an opponent be somehow capable of retaining their body structure upon being initially struck by the Sōkotsu, the neijing forces would continue to bounce off one another by trading energy between one another due to their never-ending collisions and also feeding off of the victim's own internal energy, continuously wrecking havoc within the body until the target is ultimately and utterly obliterated until not a trace of them remains. It is due to this reason that Seireitou considers his Sōkotsu to be a weapon of supreme destruction and restricts himself from ever using it in a fight unless it is truly needed. Due to the degree of devastation that the Sōkotsu can wreak, Raian advised him against using it within the walls of Seireitei, where it could cause "unintended mass murder and devastation"; even when pitted against a multitude of opponents.


 * Hyakūmai Sōkotsu (百倍双骨, "Hundredfold Double Bone"):


 * Yōko Tōkotsu (妖狐頭骨, "Demon Fox Skull"): An ultimate application of the Ikkotsu and Sōkotsu principles, the Yōko Tōkotsu is a powerful technique that is reserved as a trump card in Seireitou's arsenal of Hakuda techniques. It begins by him holding out his open hands with the palms facing the target, the left hand held right-side up and the right hand held upside down, and clapping together the bottoms of his palms together, which creates a pressurized spark of friction so great that it takes on the appearance of flames and forms the shape of a large kitsune head, complete with physical features such as eyes and ears, which surrounds his entire person and is great enough in size to completely block out the skies momentarily. Upon reaching and striking the target, the mouth of the kitsune opens and devours the target in a blaze of pure frictional force, ideally reducing the victim onto mere ashes. The resulting blow subsequently causes a release of pressure that expands outwards and overtakes an entire landscape, causing trees and plants alike to become uprooted in the wake of the Yōko Tōkotsu. Despite others suggesting that this technique is akin to a Kidō, Seireitou firmly denies this claim as its power comes solely from pure pressurized force and friction rather than reiryoku, allowing him to classify it as a true Hakuda technique.


 * Bassai (휴식 (バサイ), Basai; Korean for "Tearing down the Fortress"): Not Yet Revealed


 * Kaerikotsu (帰り骨, "Returning Bone"): Possibly the most devastating and dangerous defensive technique in Seireitou's Hakuda arsenal, the Kaerikotsu is a nearly invincible defense that employs the concept of neijing. By the utilization of his own neijing energy from within his body, being used as a bounce-off point, Seireitou can make it so that the physical attack of an opponent is unable to harm him and instead causes it to harm the attacker. In allowing the physical force to make contact with a part of Seireitou's body, the point of contact being the opponent's own body part being used to carry out the attack, the force of that strike reverberates in the opposite direction of the applied force, thus causing an immediate responsive counterforce in equal magnitude to the strength used by the attacker, causing that force to vibrate back through the opponent's body in the same manner it was being thrust outwards. Such a feat leads to the opponent's force returning into their body, fanning out inwards as if Seireitou himself carried out the assault, resulting in the opponent's internal biological systems being harmed severely, possibily even destroyed, in direct correlation to the amount of force that they themselves used to attack with. In essence, an opponent's force is returned in equal magnitude without Seireitou needing to expend any energy himself, or rather insignificant portions of energy, to bounce off the assault. The same action can be carried out if an opponent were to strike Seireitou with a weapon, causing said weapon to break apart if used without care. An opponent of significantly weaker power, attacking Seireitou with his Zanpakutō, would end up causing his own Zanpakutō to shatter into pieces while subsequently damaging his own hands from the naive assault. Against very specific energy attacks, such as the Getsuga Tenshō which deals a direct linear assault, Seireitou has been shown to use this defense to make it seem as though the attack had no effect whatsoever, despite whatever amount of power that is applied into the attack. The Kaerikotsu is very easily one of Seireitou's most invincible defenses.


 * External Manifestation: It is possible for Seireitou to materialize the Kaerikotsu through the very force of his killer intent. Through a mere gaze, he can erect what seems to resemble a barrier composed of pure spiritual energy, but in actuality, is but pure force of will that serves as the Kaerikotsu's medium. Once an opponent's attack makes contact, the power from their attack is apparently "soaked" into the wall of force and then exerted back outwards in a truly magnificent explosion; carrying the exact same properties as the original Kaerikotsu, however, the return force is less gracefully expressed. Since the original technique allowed for Seireitou to choose how to return the force back onto his source, thus making it possible for him to adjust the attack's properties in any way he sees fit, this external use merely smashes the force back onto its originator with the intent of delivering the same amount of force at them. While it is unrefined, Seireitou states that the immediate explosion makes it impossible for an opponent to counter the Kaerikotsu's return, thus ending any hopes of "playing ping-pong" with the attack in question.

"Radiating Fist" (☲): Though commonly mentioned in the practices of neijing, which utilizes internal energy, there also exists Hakkei (脂肪強, roughly translated as "explosive/raw power"). It is often practiced in Karate through the training method of sanchin kata. The purpose of Hakkei is to allow the fighter to use their energy in an explosive manner with the least amount of actual physical movement possible. In essence, it is the "strike without striking", causing the muscles within the body to actually generate the energy and deliver the force of the attack without actually carrying out the attack. In doing so, Seireitou can attack with immense force even if he is extremely limited in space, allowing him to attack with great strength no matter the situation. By merely tapping the opponent's arm, he can cause his explosive energy to generate an attack and crush the joints despite the fact that, to the untrained eye, Seireitou did not preform any sort of technique. Though unnamed, as it has been forgotten in the modern age, there is actually a method of transmitting force in the opposite method to that of hakkei. Rather than the force discharging at the moment of impact and rippling throughout the medium in devastating waves of disruption, the force harmlessly projects through the medium for a determined period of distance and time before releasing the built up potential force, causing a similar type of explosive force release that is found with typical hakkei. It is characterized as being extremely difficult to master, eons more so than the general form of explosive force transmission, for it requires an absolute self-control over one's body that is unsurpassed by the hoi polloi of martial arts. Seireitou is capable of utilizing this flipped form of hakkei on a whim, punching or even kicking at the air and allowing his force to cause a tremendous explosive release at any location of his choosing.
 * Tsukiyubi (撞指, "Thrust Fingers"): By focusing the Hakkei force through the contact point of his two fingers, Seireitou generates a powerful thrust-like effect upon a simple touch upon an opponent's body. The result is instantaneously, immediately sending the target flying a considerable distance away along with causing them some degree of internal and external damage. Seireitou claims to have taught Shunsui Kyōraku this Hakuda technique.
 * Hoshikudaki (星砕, "Star Destroyer"): Not Yet Revealed

"Exciting Fist" (☳): Heat itself is born from the vibrations of particles that are sped up by external and internal forces. With this understanding, Seireitou can excite the reishi around him to generate incredible bursts of blue fire; it is a blue because of the coloration of the spiritons, though they become red/orange when exciting kishi particles. It has been noted that the flames generated by the Sokushin technique are almost exactly the same to the Heiliges Feuer, something Seireitou had commented to have played an important role in the inspiration for the Sokushin technique. The blue flames appear to be strong enough to actually burn through the rocks of Hueco Mundo which are normally resistant to flames. While the flames are, on their own, quite hot and extremely lethal, Seireitou can actually increase the heat and temperature by simply willing the vibrations to further accelerate. In some instances, he has revealed the capability of speeding up these oscillations so much that they result in enormous explosions of great destruction. Despite boasting such incredible might, because this is simply the act of willing the vibrations to go faster, the flames that Sokushin creates exist only in the spot in space at which Seireitou enacted his will. This limitation can be rendered void by simply utilizing Hōkōryū to transition the blue embers and move it in accordance to his whim. While this can be done normally through mental command, Seireitou also prefers to engage in physical combat, allowing the blue flames to erupt outwards in order to supplement his actions. Muken can also be applied to the Sokushin, creating large fiery fists that crush everything before them. By using the Spirit Wave, it also becomes possible for Seireitou to acceleration the vibrations of reishi that compose spiritual beings, such as Shinigami and Hollows; however, it is noted that this is a far more difficult, albeit still possible, task in which the effort needed to successfully carry out the technique is proportional to the will that the target possesses. While potent and effective, the flames pale in comparison to the white flames of Hanullim.

"Stilling Fist" (☶): Stillness... a simple term which conveys a large aspect of the martial arts. When the mind and heart have become completely still and focused, like that of a perfect crystal, comprehension of the enemy and the world become clear as undisturbed water to the martial artist. While many misconstrue this as some sort of inner peace, it is actually a state of acceptance. Whether evil and doubt lurks in the heart or not becomes irrelevant, as accepting them removes whatever possible influence they may possibly hold. And in such a state of mental stillness, basicity returns and all things may become anew. Therefore, in actual application of this concept, through means of projecting such stillness onto the world around him instead of within, Seireitou slows down the reishi vibrations to the point of utter stillness, through this "silence of the heart". The technique makes it possible to actually eliminate the oscillations which provide particles their orientation and subsequently renders them completely and utterly still. Causing reishi to lose their vibrations means that they no longer possess the illusion of their unique appearance and actually emit a faint glow due to their stationary existence, becoming something akin to crystals. Allowing several reishi particles in the same area to all become influenced by the Shijima technique means that Seireitou can produce crystal-like walls and various structures to act as shields, among other potential constructs. It is often mistaken as a sort of magical abiliy which conjures ice and emits this onto those the user wishes. It is, in truth, an act of Hakuda. The theory behind Shijima is to will forth the vibrations to slow down so that the binding forces which maintain their molecular state of unique existence can tie them together to complete packing efficiency; such as water vapor being chilled to return to its ice form. By combining this technique with Hōkōryū, he can actually move the crystallized reishi constructs for the purpose of practicality in combat and other associated endeavours. It is possible to manifest the Shijima as a burst of icy-cold wind through mental command or even through his own body, serving a purpose of freezing all targets subjected to its effects. A large-scale version of the aforementioned manifestation allows him to actually transform the landscape into a frozen tundra. Cold air appears to slowly exude from his person when he calms his heart and enters "silence", literally seen from his breath, which normally serves as an indictator that this technique has been put into action. Despite few actual uses, he rarely utilizes the Shijima technique, meaning that its full nature has yet to be truly ascertained. He demonstrated the Shijima within the Dangai Precipice World, where he imposed his will to "silence" the force of Reason around him in order to stop the flow of the Kōryū; similar in principle to the purpose of the Kaikyō Kotei device.

"Receptive Fist" (☷): Not Yet Revealed
 * Kyūsho Iyashi (急所癒し, "Vital Point Healing"): As the name implies, it is a technique developed by Seireitou that allows him to heal a person's damaged body through the activation of their internal dormant energy using his own energy as a catalyst, using their pressure points as the point at which his energy may enter their body. This reaction causes the, now active, internal energy to act by healing the points in the body where the damage is most heavily concentrated. From there, the internal force spans outwards like a pool throughout the body, healing all other points of damage, until the entire body is healed to physical working order. However, despite how useful a technique it is, several of the motions involved in this technique are rather inappropriate. They are very clearly identified as sexual foreplay motions, even though Seireitou denies this. It is further supported by the fact that sexual actions are involved in the technique's application due to Seireitou claiming it will only heal women, despite how obvious a lie that is. However, as morally reprehensible as it may be, the technique is highly effective, able to completely restore a body to full working order despite how badly damaged it may have been.
 * Huàn Shǒu (換手 (手を変える), Huan Shō; Chinese and Japanese for "Changing Hands"): Said to be a contributing ancestor to Jujutsu and even Aikido, as well as other soft-type martial arts, the Huàn Shǒu is an ancient art that completely treats the individual themselves as an interception between two or more specific points. Seireitou claims that the style requires the user to have truly acheived mastery over their five senses to the highest degree, thus producing a sixth sense that allows them to feel out their opponent and even the world around them without needing to physically perceive the actions. In the case of an enemy's attack, Seireitou demonstrates the Huàn Shǒu by intercepting the intention and flow of the attack by re-routing it through an alternate medium. They use themselves as an interception rather than serving as the opponent's medium for assault, causing an attack to flow through their body, carrying it away, and directing it through another medium. When an opponent throws a punch, their intention is to strike their target and cause concussive damage onto that target. When an adversary utilizes a fire spell, they are intending to burn their opponent. With the Huàn Shǒu's principles, Seireitou can redirect the punch's force through an alternative medium, such as causing the ground beneath him to crack apart while leaving his body completely safe from harm. In the case of the fire spell, he can cause the air itself to heat up or the ground to melt while he himself is unaffected.

"Expansive Fist" (☰)


 * Reihikari (魂光, literally "Light of the Soul"): After mastering his Bankai, Seireitou had applied the concepts of utilizing his reiatsu as a source of energy instead of merely projecting it as a spiritual pressure. By cupping his hands down at his waist, in which the hands are at least very close or touching one another, the latent reiatsu is converted from spiritual pressure into a mass of pure energy, typically taking the form of a uniform sphere, to which Saori Sumeragi had commented on the aura that the energy was emitting, questioning if it was "really reiryoku", subsequently noting that it was not even a form of Kidō eventually reaching the conclusion that it was the "very force of his tremendous reiatsu, taking a physical form at his palms." The hands are then thrust forward to shoot out a streaming, powerful beam of energy. The attack can also be used, generally under extenuating circumstances, with just one arm or even with the legs. While the strength and effectiveness of the technique is dependent on the amount of spiritual energy Seireitou puts into the attack, it is typically a very powerful attack, capable of literally disintegrating an opponent if enough strength is put into the technique. The destructive capabilities only increase with the more power that is pumped into it, though its power was able to completely decimate a large portion of the Seireitei at half-power. However, what makes the Reihikari such a dangerous technique is that it is literally the manifestation of Seireitou's will, just like that of his Hakuda styles, that takes the form of pure spiritual energy; although nothing could be farther from the truth, as this technique can obliterate obstacles that normal attacks fueled by reiryoku can not hope to do. In some cases, Seireitou will chant the words "Rei-Hi-Ka-Ri" while charging the technique, and then shout "Hah!" when firing the technique. Seireitou has shown various methods to using this technique, very well making this technique the most versatile of all attacks in his arsenal.


 * Multi-Focused Beam: It is possible for Seireitou to further focus the latent energy that powers the Reihikari technique, forming a dense beam of white reiryoku which fires from the palms of both hands that disintegrates everything and anything in its path. The attack quite literally vaporizes anything within its blast range, even other techniques that are composed of spiritual energy, leveling the targets until nothing remains. Seireitou has also demonstrates a far more controlled and significantly smaller version of this focused Reihikari by using a mere finger to execute the attack, forming a laser beam that fires from the fingertip and strikes through the target with strict ease.

Master of the Hyeong: Under Construction

Suiryūsei (水流静, "Water Flow Control"; literally "commanding the movement of the water"): Truly one of the ultimate expressions of soft-type martial arts, the Suiryūsei is a technique designed by Seireitou himself and is acclaimed to reach a pinnacle of Hakuda when used by a person of his precipice of power and technique. In accordance with soft-type martial arts, the key is facing an opponent without intending to fight force with seemingly superior force, but rather to use the target's own power against them in some advantageous manner. Therefore, the Suiryūsei is a technique that finds the most effective method at allowing Seireitou to express this soft-type motive at the most extreme level possible. While the technique requires an absolute stillness of the mind and of the energy within the body, through the concept of Seihaku, Seireitou had mastered his own discipline to the point that he may engage in intensive combat with his soul excited through the use of Dōhaku without causing the Suiryūsei to lose potency. However, Seireitou gravely cautions those who attempt to use his technique to maintain complete control over their emotions and to keep an absolutely calm mind; otherwise, the skill is doomed to fail and the user may possibly lose their life. It is only because of Seireitou's unrivaled skill as a Hakuda Grandmaster that he finds himself capable of using Suiryūsei without fear of such a possibility; as if it were second-nature to the man. Seireitou comments that the Suiryūsei's full power is only possible when used by someone that has mastered the Seihaku; ideally making this technique one that exists on the precipice of a Grandmaster. After learning that Minato Kuramoto had become a Hakudaka whom uses the basic form of Seihaku, Seireitou had taught him the Suiryūsei, to which the former is capable of using it on a basic level due to lacking the level of prowess that his master does. It operates according to three general principles, or rather "levels", which follow one another in a sequence.
 * Understanding of the Flow: Comprehending the opponent's flow of energy, or rather understanding one's opponent and feeling their rhythm, is a critical necessity in truly mastering the martial arts. It is through such a feat that one is capable of perceiving the nature of their target's spirit. An untrained Hakudaka attempting to use this level of Suiryūsei may actually inadvertently lose concentration based on what they discover through this newfound perception. In addition, for any normal user, such an act takes a considerable amount of time, as they would need to fight their opponent (or rather, "spar" with them) for a sufficient length in order to truly comprehend their fighting flow so that Suiryūsei will become effective. However, to Seireitou, who can instantaneously discover information about his target within seconds of confrontation, such an act bears no time restraints. The feat of understanding and analysis is child's play when dealing with a person of Seireitou's level of prowess, meaning that Suiryūsei's first level is something almost instantaneously activated and completed in accordance with Seireitou's whim and motive alone.
 * Suikyōdachi (水面立, "Water Surface Stance"): Developed for the purpose of serving as a stepping stone between the first and second levels of Suiryūsei, the Suikyōdachi is a defensive stance that specializes in redirecting the distribution of force by an opponent's incoming physical strikes. It is called a "stance of no stance" (無立の立, mudachi no dachi), as it does not take any discernible nor studied body position and often changes in response to the situation. Anything that enters within the designated radius of influence from the user's center is vulnerable to its directed force being compromised at the moment it comes into contact with their body, provided that they are aware of the attack itself and its nature. The force behind the attack is carried into the body via the positioning of the user, due to the characteristics of this stance, and can then be channeled through the body to another outlet, such as the opposing hand or even one of their legs, and subsequently delivered onto the opponent as a strike of equal force. Releasing the force in a timely manner is crucial because if this force is carried for too long, the user can actually cause internal damage to themselves; though, to Seireitou, such a consequence can be effortlessly diverted. Additionally, by simply turning the wrist and the subsequent turn of the palm or fist when blocking an opponent's strike, one can actually release the blocked transmission of force akin to the act of allowing gas to escape a vacuum-sealed container through a small opening. The opponent, in turn, experiences a feeling as though their attack was "absorbed" because they can clearly see their strike making contact but cannot feel their attacks actually connecting. He explains that it is meant for "occupying an enemy's territory" and to a master of his stature, any enemy that enters this space is almost guaranteed to be defeated. It is likened to a physical usage of shogi, a game which involves positioning yourself at a point where you are at the greatest advantage. It is seen as a large sphere of reiatsu that surrounds the upper body of the user, and its size is directly associated with the user's mastery. Klaus, being a master of Hakuda in his own right, saw no reasonable opening when confronting Seireitou, feeling almost frightened at the size of the sphere when crafted by Seireitou. The true purpose of Suikyōdachi lies in the power to manifest the strikes of Muken instinctively, so as to crush all manner of opposition that move within its range. It stands as the first line of defense against all manner of attack. When mastered to a certain extent, according to Seireitou, the Suikyōdachi can be reduced to a thin layer above the skin for the purpose of dodging the opponent's attacks at the last possible moment. An absolutely calm mind is necessary to use it, as even a slight degree of emotion will disrupt the technique. This is because the technique involves understanding one's opponent and feeling their rhythm.


 * Aiki (合気, literally "Joining Spirit"): Otherwise known as the concept of "entering/merging with the flow", it is perhaps the most commonly used level of the Suiryūsei in Seireitou's hands, the second level involves using the knowledge of the opponent's flow of energy and entering the flow; essentially becoming one with the target and their movements. While a normal user interprets this as simply combining the movements of the opponent with their own, to serve as a set-up for the third level, Seireitou has taken the second level to an extreme measure by completely mastering the idea of "merging with the flow". Suiryūsei will allow Seireitou to effectively enter the energy flow or movement of anything that he identifies as the target. Whether it be a substance, an enemy's attack or defense, a technique, a weapon, an opponent themselves, or anything in between, everything that exists has a flow of energy which Suiryūsei can analyze and then allow Seireitou to enter within its flow wavelength, essentially merging with it. The results that occur from such a union are often random and various, difficult as it ranges from target to target, as the two or more souls attempt a forced joining for an indeterminate amount of time. In the situation of Seireitou merging with an opponent, the two beings can actually become one, with certain traits overlapping and changing in the unison. Depending on the willpower of the individual or collective target(s), Seireitou may be capable of actually completely controlling their body and mind, allowing him to act whilst in such a unified state. He'd even be capable of accessing their abilities and memories, among other things, so long as it is within some degree of the scope that consist of his own powers. This is often represented by their hair becoming white in coloration. To an opposite extreme, the Suiryūsei's second level can even allow Seireitou merge his being with the intended target and render his influence silent within them, in order to ideally hide within the target and await a desired moment for escape. This proves quite helpful in pursuing an ambush or sneak attack. It appears that the technique does have a fail safe that allows Seireitou to escape and "break" the unification whenever he should deem necessary, even if the target is aware of his presence within them and are capable of struggling for control. However, he does note that against certain opponents whom could command control over energy flow that would rival his own, even an act of escape from the union would be close to impossible. It has been likened to that of the Hōgyoku in that the barriers between the souls of Seireitou and the target(s) are removed temporarily in order to allow for a successful merging. However, in order to prevent "soul suicide" from occurring, Seireitou maintains stability through his own will, and because of this, the complete merging that involves taking control of the target may only last for a specific length of time. The second level of the Suiryūsei was crucial in Seireitou's attempt to master the Shukuchi, as it allowed him to identify the "world's flow" as his target while merging with it, making it possible to engage in instantaneous teleportation.
 * Shūran Suigetsu (収覧水月, "Grasping the Water Moon"): Based upon Suiryūsei's second stage, which after one learns the flow of their opponent, they can now merge with the flow and move together with them as though they were one and the same. Seireitou had developed this technique after having thoroughly studied Quanyin's observation methods. This technique is considered the "ultimate defense" as it, in a theoretical perspective, essentially permits an ability to avoid any and all attacks. After Seireitou manages to read and analyze the flow of his opponent, he can actually will his body to avoid the source of the flow he has managed to understand. It is the same as when a martial artist manages to study their opponent and move in such a way that allows them to counter the pattern of attacks used by their opponent. When he learns of an opponent's flow through Suiryūsei, it becomes possible to simply will himself to dodge that particular array of patterns and flow of energy, even without perceiving their specific existence; making it impossible for that individual to actually come into contact with him. Ideally, one can consider Shūran Suigetsu to be akin to a barrier of sorts that immediately trigger any necessary movement on the part of Seireitou, even if his senses do not catch wind of the move, to evade and dodge the opponent safely. It is even possible to weave together counterattacks into the Shūran Suigetsu's initial dodge to further enhance its efficiency in combat.


 * Disruption of the Flow: The true nature of Suiryūsei's third level is rather unclear, especially when in Seireitou's hands due to the latter often stopping the technique after the second level. The idea behind the third level of the Suiryūsei is utter disruption and destruction of the target's flow or movements. While it hasn't been outright used by Seireitou in any notable confrontation, he expresses that it serves as a true finishing move, especially in his hands. The third level is also the most difficult to learn how to utilize, regardless of the method at which it is used. It appears that he dislikes having to resort to the third level of Suiryūsei because it can lead to the deaths of his targets; although, it appears that he can tailor the Suiryūsei at this stage to instead deal some sort of significant effect onto the target instead of causing their end.

 * Kutō Jigoku no Ranbu (苦闘地獄の乱舞, literally "Wild Dance of the Excruciating Hell"): Utilizing the principles of Aikido and Jujutsu in contemporaneity, this is a finishing move created by Seireitou to deal the most agonizing punishment to an enemy without killing them. It involves, in the following order, a strike which interrupts the enemy's flow of movements, a throwing move that compromises the opponent's center of gravity so as to force them to lose control over their body in a brief instant, and then multiple simultaneous joint locks to essentially render them a pile of broken bones. The initial strike serves to first disorient the opponent while the following throwing move negates the possibility of their recovery quick enough to escape the final third step of the technique. Once their center of gravity is compromised, Seireitou then causes forceful joint alterations which quite literally snaps the joints of the opponent's bones in various locations; this can include the elbows, knees, ankles, waist, shoulders, and wrists, all of which are snapped within the same instantaneous moment and contorted around to basically mold the enemy's body into a broken mess by locking up the body's limbs together and tying them up like one would tie up a box. It causes such excruciating pain that many who witness Seireitou pulling off the technique note that it would've been better off to just kill them rather than use this technique on them; with Minato Kuramoto questioning how this would even be allowed under the principles of Katsujinken. Because of how this technique is designed, it is quite impossible to prevent the execution of the final step unless one manages to prevent Seireitou from either interrupting their sequence of movements or compromising their center of gravity; which, due to the speed at which this entire combination is executed, requires only one of considerable skill to even attempt escaping.
 * Amahiyaku Ōmiko no Jūjite (天飛躍大狐の十字手, "Cross-Shaped Hand of the Heavenly Leaping Majestic Fox"): Not Yet Revealed

Stage of Ri — "Transcendence"
Muken (無拳, "Empty Fist"; literally "fist of nothingness"): Reserved only for those whom have reached the absolute pinnacle of Hakuda, there exists styles of such a combat field that allow for actions that are "beyond the physical". Those who reach this level are known to have ascended beyond the realm of standard hand-to-hand combat and have reached a precipice far beyond standard comprehension. No longer do their movements become restricted by physical limitations, nor by any form of distance, nor their techniques by logic, as they completely abandon causality. In doing so, the warrior no longer becomes a simple fighter, but a weapon of force in its purest sense. He is the embodiment of an army, taking the form of a single man, turning any form of confrontation into either a massacre, genocide, or a war; perhaps even each of them in a single instance. Having disregarded cause in and of itself, the Hakudaka is capable of producing techniques without the actual need for physical engagement of the opponent(s). The attack truly occurs, the block truly occurs, the joint lock truly occurs... but also does not. The Hakuda Grandmaster needs not to undergo the cause behind what his attacks can do, as now there only exists what the technique is and the end result of unleashing it upon an opponent. Seireitou explains that it is the act of materializing one's will to "strike", the attack crushing down and tearing apart any and all opposition that should meet Seireitou's perception. Muken is essentially a representation of Seireitou's own body, manifested through force of will, which can materialize as either his hands or even his legs and feet. These often follow along with the motion of his own body, to enact the will to strike rather than the attempt of striking. Anything that can be interpreted as an attack can be blocked and anything that is a target will be annihilated without prejudice. The empty fist knows only to do as Seireitou wills it to, allowing him to crush the forces of any substance, be it even an element of nature itself. Even illusions can be broken and hypnosis shattered by the Muken, as even Kidō cannot hope to stand against it in overwhelming superiority as it is normally accustomed to. He can even tear apart a Haien in the form of a massive wave of flames without fear of its great heat, as the heat that the spell emits, just as the actual flames themselves, suffers total destruction at the hands of Muken. Those of similar skill class are capable of perceiving the attacks, to some degree, but to most opponents, it would appear as though the technique had occurred without Seireitou actually having preformed said technique; at least, to their knowledge.


 * Empty Transmission of Force: Seireitou has demonstrated the ability to apply force distribution with the Muken in the same manner that he would normally do with his own punches. The result in doing so makes a single Muken palm strike possess incredible explosive qualities that can destroy an opponent with a single shot should they be struck head-on.


 * Senju Shakate (千手釈迦拳, "Thousand-Skills Buddha Hand"): By projecting his Muken through his reiryoku, Seireitou essentially manages to create massive energy constructs in the shape of fists that can annihilate the opponent with overwhelming force. Raian Getsueikirite noted the attack to be similar in basis to that of Kidō. While the reasoning behind this technique is to simply provide physical shape to his Muken so as to execute an even more destructive assault, many assume that because it is made out of reiryoku, it can be absorbed like any other form of energy. However, this is incorrect. In fact, it is considered extremely dangerous to attempt to absorb these fists. Just as a normal punch is blocked by an opponent via a block, martial artists have been known to call this action "absorbing the blow"; referring to the idea that when an opponent blocks a punch, they are essentially absorbing the force behind it and neutralizing the attack's potency. The danger lies in the fact that a punch given by Seireitou can be subjected to certain levels of force distribution. He can freely project the force of his punches, in the same manner he executes the Ikkotsu, meaning that for an opponent to even dare attempting to absorb the force behind the punch would be disastrous and opens them up for massive internal damage. The same can be said in a case of absorbing the reiryoku of his fists. When an absorption technique is applied, it is basically attempting to impose their will onto the source of energy so as to claim it for themselves; the exact same principle as blocking and absorbing a normal punch. Therefore, once an individual attempts to absorb the Senju Shakate, whether by physically blocking it or by trying to absorb the reiryoku, they are allowing a bridge to form between Seireitou's Muken and their own bodies, allowing him to project the force straight into their bodies and inflict tremendous amounts of damage. Therefore, blocking the Senju Shakate is impossible. In order to avoid being struck, the only possible ways are to either dodge the attack or to resist its strength with an appropriately great enough durability. However, in the case of the latter option, internal and external damage is almost always guaranteed to some degree. One of the most devastating applications of this technique is to combine it with the properties of a neijing internal assault, inflicting a tremendous wave of force rippling through the target's body in a single instant; sufficient in ripping apart any individual should the strike be a clean hit.


 * Senri Tsūtenshō (千里通天衝, "Heaven-Piercing Palm of a Thousand Ri"): Derived from the core principles of Muken, it is possible for Seireitou to manifest a massive open-palmed hand that allows him to strike at a target with immense force and strength behind its thrust. Ideally, with reference to its name, it is capable of sending a victim flying away a distance of at least a thousand ri. The hand is typically slightly greater in size to that of Seireitou himself but can expand to even greater sizes in accordance with the necessity and intention of the technique. It appears as an exact large-scale proportional replica of Seireitou's own hand, complete with bodily features, and can be controlled by the motions of Seireitou himself. However, it can also be used in a more spectral form, similar to the Senju Shakate technique. Unlike the original Muken technique, which manifests Seireitou's will to strike in the form of a fist, which would be meant solely for offensive combat, the Senri Tsūtenshō ideally allows him to perform the same techniques he would have been capable of utilizing as himself, but on a far greater scale. This can extend even to Kidō; ideally allowing Seireitou to perform massive scale versions of normal Kidō spells that can devastate an army of opponents.

Hōkōryū (方向流, "Directional Methods"; literally "method of direction"): Everything is energy, whether it may take the form of sentient beings, nonliving materials, the supernatural, or even the intangible substances such as thoughts themselves. In the soft-style martial arts, the use of redirection, manipulation, and overall avoidance is strictly emphasized of the opponent(s), whom of which may be considered simply a form of energy to the eyes of the martial artist. Therefore, it is possible to apply these teachings in a manner similar to the concept behind the Muken art, allowing a being of Seireitou's ability to move beyond the physical and preform absolutely mysterious and mystical feats. To the untrained eye, one may assume he is utilizing a form of Kidō, but rest assured, it is still Hakuda that is being expressed. Without requiring any form of actual physical contact, Seireitou can actually provide "direction" to any form of energy that he may deem. Be it the physical strike of an opponent, an attack of spiritual means (Kidō, Cero, et cetera), or otherwise, Hōkōryū will allow for the projection of Seireitou's martial will, resulting in the application of such techniques of manipulation. Aikido teaches the act of avoidance, aiming to take advantage of timing and footwork to use an opponent's movement to not only dodge an assault but to assume a position that can be deemed the most beneficial. Jujutsu teaches the act of manipulation. Even when confronting an opponent of seemingly great danger, such as one weilding a weapon when the martial artist is unarmed, this style teaches techniques that will for besting the opponent in any possible manner; disregarding, at times, moral sense entirely. Without a doubt, all of these teachings and those that follow similar traits (in other words, any form of soft martial arts) can be used through this mysterious method of materializing the will to "throw" and/or "redirect", among others. In truth, the art of Hōkōryū stands to be the "evolved" form of all soft-type martial arts. Seireitou describes the feats produced by Hōkōryū by first explaining that all forms of energy function by following a path; in other words, everything operates by the rules of the energy flow of which it naturally exists within or has been willed into. His will literally materializes into a "flow", providing a new path for the energy to follow. The act of doing so allows for a variety of abilities on the user's part. Seireitou can intercept energy attacks without a single physical motion, causing it to completely change course from striking him to being redirected according to his whim. It is also possible to even absorb the energy within him, literally causing the flow that his will materializes to move within him and to become "trapped", allowing for some form of either present or future use; symbolizing the concept of joint locks. When using Hōkōryū against an attack produced by, for example, a Grandmaster of Kidō, it quite literally becomes a "tug-o-war" between whose will maintains dominance over the technique; a struggle which can have disastrous effects to the battlefield between and around the two or more combatants. Though it does not have a specific name, Seireitou had demonstrated the ability to use his Hakuda Grandmaster technique, Hōkōryū, to actually generate massive structures or constructs that follow an energy flow of his design out of the energy that he has successfully imposed his will over and took advantage over for his own devices. This was first displayed during a full-scale battle against several powerful beings, in which he drew in the attacks of each and every failed attempt at overwhelming the silver-haired man with brute force, and created a construct of this energy around his person that stood for the purpose of a nearly invincible defense; in direct proportion to the amount of energy drawn into it. Bending and curling around his body, the Hōkōryū begins to redefine the original energy flow of the absorbed energy into what Seireitou himself deems it to do, turning it into a power that is all his own.
 * Kyūshū Dageki (吸収打撃, "Absorbing the Blow"; literally meaning "to absorb the impact of the blow"): In the martial arts, it is common during sparring sessions to practice the art of absorbing the blow of the enemy. It is a defensive maneuver which weakens the effects of an opponent's strike through their methods of conditioning, allowing for a counterattack which can be delivered during a window of opportunity. However, in the hands of a master that has transcended the physical, allowing them to perceive even mental and spiritual assaults as a strike and respond appropriately, they are able to take the definition of "absorbing a blow" to its utmost levels. In doing so, the act of absorbing a blow becomes possible for not just a physical attack but any form of attack. Whether it'd be a Zanpakutō technique, a Hollow's technique, Kidō, and even Quincy arrows, anything that is classified as reiatsu/reiryoku or uses reiatsu/reiryoku as its primary component is susceptible to being absorbed so long as it is perceived as a threat by Seireitou.

Conceptual Martial Arts


 * Kyojitsu (虚実, literally "Art of Truth and Falsehood"; also translated as "method of manipulating truth and falsehood"): Mortals are such contradictory beings, flickering back and forth between truth and illusion as though it were their innate nature to do so. Everybody lies. It is the greatest strength of a mortal to utilize deception in order to garner that which they seek from victims but more so to ensure their own survival when all other means have failed. Martial arts, in the hands of the humans, therefore were all born with the same idea that deception creates the necessary foundation. There are always those novices that engage in straightforward combat, wielding naught but truth in their fists as they confront their opponent. But to those that have become seasoned by the experiences that arise from an association with the world of martial arts, truth is no longer enough. Vulnerabilities become apparent to the equally skilled and studied enemies, for it is not difficult to ascertain the truth behind behavior and action. Movements hidden within movements, intimidation tactics designed to force an opponent into revealing an opening, and even eccentric tricks that would never be thought to have any use on a war-ravaged battlefield, are all concepts within martial arts that the masters of these crafts eventually learn to utilize in order to properly fight against the truth of an opponent that possesses the power necessary to crush truth by conventional methods. But this is where a mortal reaches their limitations and the martial arts practiced by humans are so restricted. They can choose how to deceive their victim, the method in which they do so to set up for the truth of their techniques to have a decisive effect on their opponent, but ultimately, deception can never be truth and truth can never be a lie. False movements can never be made to be real. After all, how could mere humans ever will forth such things? Kyojitsu, the true art as mastered by a person of deity-like standing, such as Seireitou, only reaches its highest purpose when utilized by somebody that has transcended the mortal realm of martial arts. Manipulation of truth and lies during the heat of battle, at that point, becomes nothing but a game to Seireitou. He can quite literally breathe truth into the lies his martial arts imposes, and in the same vein, he may rip away truth from truth and turn his own actions into lies. It operates upon the principle of manifesting one's martial will onto the world and using it to manipulate the truth and falsehoods of one's own actions. On the physical plain, a mortal has but a single body, a single pair of arms, and a single pair of legs. Therefore, no matter how fast or strong they are, these are numerical limitations that can never be overcome without assistance. But the will of a martial artist is infinite, proportional only to their conviction and desire, meaning that for a Grandmaster such as Seireitou whom can manifest such a thing, it becomes possible to utilize his own will as though it were an extension of his own being. The result of this being an ability to make false movements, such as feints, into actions that can interact with the world and have a real effect. For example, a trick as basic as creating afterimages that are left behind in the wake of his superior speed, would normally be considered a technique which gives rise to falsities. After all, they are just transparent illusions designed to make an enemy believe Seireitou is still within a single instance of spacetime, when in reality, he has already shifted his person elsewhere. With his method of Kyojitsu, he can instill truth into these illusions, allowing him to create actual clones that possess life and consciousness of their own. Of course, they are still one with the source, but they are lies that have been manipulated into truths. And yet, this is but the beginning of what Kyojitsu can become when used by Seireitou. A dying art that has been abandoned by mortals, as their minds simply can not comprehend its vast applications nor could they ever hope to acquire its secrets. It is an art that shall remain with the Hakuda Grandmaster and those worthy enough to be entrusted with it.

Kannagara no Michi (随神の道, "Way of the Gods"; literally meaning "the way which accords to the kami" or "the way as it is with the gods")
 * Taiyōbu (太陽舞, "Sun Dance"; literally "Martial Art of the Sun"): Ever since the days of the ancients, man has observed the elements of nature in order to survive. The ever-present danger that surrounded mankind threatened their survival in many different forms, until such a point that they had no choice but to study their enemy. But what was once their foe would also serve as their greatest teacher, for it is through this initial observation that the first martial arts were born. Watching as the waves danced between the shores — the tides in a push and pull relationship — were among the first teachers that brought forth the birth of the soft martial arts. Of course, this was only possible because water and its movements were visible. The ancients understood how they could gain strength and power from mimicking nature's behavior but even so, the almighty source of all power still alluded their mortal grasps: the Sun itself. Of course, as the centuries passed and turned into millennia, the power of the Sun could be harnessed with indirect methods; regardless, the martial arts could not benefit from the Sun's power. But this was because, not due to any fallacies that lie with the martial arts themselves, the mortals that attempted to practice them with their limited capabilities; weaknesses not found in the spirits that attained a precipice of martial art mastery that could only be realized due to their condition. The ancient spirits, devoid of mortal flaws, studied the core of the Sun's powers; that of the great lady Amaterasu. How was it that she was able to shine a light that carried such devastating power, and yet, remained at harmony with all of nature? Despite the overwhelming heat of the Sun's light and the power of fire itself, the fragile system of nature remained peaceful with the great circle in the sky that produced such immense heat. It was through this observation of the goddess that the ancient spirits mimicked the relationship of nature and the Sun's heat, learning to become harmonious with sources of heat and fire, which led to them actually manifesting flames from their body as they pulled in heat from the Sun and brought forth flames during their dance. Of course, this was not the true beauty of their progress. The ancients reached the point where heat suddenly did not affect them in the way that it was originally meant. This was because they were able to enter a new relationship in which they would be at peace with heat and fire, rather than at odds or as a subservient relation, and in turn, the creation of the Taiyōbu was possible. They danced with the Sun's light, as though they were dancing with Amaterasu herself, allowing them to draw upon her power while simultaneously remaining in harmony with the great circle's heat. Their understanding allowed them to further extend their applications to any source of heat; manipulating not the actual flames themselves but the heat that emanated from them. Heat would no longer be their foe but their companion in the dance of the Sun. They had become embodiments of a martial art concept that emphasized mimicry of nature's behavior, which allowed them to establish harmony between themselves and heat itself, but in the troughs of history, the ancient art was believed that have been lost; the members of the Sun Warrior Temple that have existed for well over five hundred years were known to practice a derivative of the original craft. However, in the pursuit of his training, however, Seireitou unearthed the original martial art in all of its purity and became its only master.


 * Tenchi Ryūha (天地流派, "Flow of Heaven and Earth"; literally meaning "the flowing thought of all nature")


 * Fūrinkazan (風林火山, literally meaning "as fast as the wind, as quiet as the forest, as daring as fire, and immovable as the mountain")


 * Kotomukesen (言向戦, literally "fighting that causes submission though the power of words"): Battle is not only conducted on a physical basis. In the eyes of a true Master of Hakuda, concept itself can be fended off and dealt with as though it were an assault on his being. It is this level of ability that allows martial art masters to fend off illusions and even resist reality warping in the same way they would resist an enemy's physical attack. In the realm of spirits, there exists such a thing as the kotodama (言霊, "word spirit/soul"), which reflects upon the great power hidden in the meaning behind written and spoken words. Spellcastors, for centuries, have invoked the kotodama and manipulated it in order to cast curses and enchantments onto their enemies. One of the most prominent beings in the spirit world,, is known to possess tremendous capabilities in controlling both his own kotodama as well as the word spirits around him. To a master of the spiritual martial arts, carrying a wisdom that exceeds normal prowess, it is possible to view these abilities that target the kotodama in the same manner that they would handle an opponent seeking to subjugate them through a form of joint manipulation or grappling. And as such, this makes it possible for a martial artist of Seireitou's caliber to resist attacks meant to influence the kotodama. He may protect his very existence from an attempt made on the kotodama but he may equally target a kotodama before him offensively by striking upon it through the Kotomukesen; a martial art of the mind. In a similar way to how there are stances that set up for a martial artist to counter an enemy's attack, Seireitou can actually extend his absolute self-control to his own kotodama; making it possible to go as far as to even make his own name as a carrier for a counterattack, the consequences of which would bestow some sort of effect onto his victims. It is the act of actually projecting the will to strike through the kotodama itself. He is known to have done so with his moniker, "Shiroyasha", for his war-earned title carries the consequential counterattack of severely dislocating a certain part of a victim's body should they be unworthy of speaking the name. Furthermore, he has demonstrated the ability of striking down the word defining the parts of an opponent's body and other particular targets as well; one such example being their arm, which if the strike occurs successfully, results in the neutralization of that limb's existence as an "arm" and essentially renders it useless for it can no longer function as an arm. It is due to this conceptual martial art that he is capable of resisting techniques similar to those used by Ichibē himself.

Personification of Kata

Mushin (無心, literally "No Mind"): The pinnacle of martial arts is to achieve a state in which one is free from all things; even from themselves. The limitations and doubts that corrupt our being are born from the heart and the mind, which anchor us onto the physical world. When one manages to leave the mind and heart, one may touch upon the true zen of martial arts. In the, Mushin is a practice that simply boasts control of the emotions to an extent that they can not hinder martial artists in battle. But when speaking of beings composed of fragmented wills themselves, which can be controlled to the utmost degree, the truth of the Mushin is that one quite literally frees themselves from their own restrictions; they can transcend physical limitation. When the mind becomes flowing and absolute — entering a state of purity — it may actually move together with the world flow. One's very mind can grasp the infinite flows of the world around them and move together with it as though the two were practicing kata together. Unhindered, the soul moves with the free mind as the martial artist enters a dimension in which they may conceptualize their reality. The physical act of punching, for instance, becomes conceptualized and materialized onto the world through one's will; the absolute thought of striking with the fist will occur rather than an attempt being made at striking. Seireitou's eyes demonstrate a brilliant glow of white light from his eyes as he allows himself to unchain his mind and soul during battle. But one must not make the mistake of thinking the Mushin is some type of technique or transformation; it is a state of being.


 * Thousand-Mile Gaze (千情景 (サウズンド・マイル・ゲイズ), Senjōkei (Sauzundo-Mairu Geizu); Japanese for "Thousand Sights"): Conceptualizing the very idea of his "sight", Seireitou may see the truth in all things; regardless of the obstacle, as even distance itself is overcome. This allows him, among many feats, to vanquish illusions by simply striking them down as he would strike down a physical adversary after perceiving of its existence. He is able to actually view the from a distance as far as the Kabuki District; no matter the obstructions that may lay before him. Through hearing and smell, his senses can contribute to his gaze, allowing him to glean even greater knowledge from his sight, but once he contributes the sense of touch, instantaneous teleportation becomes possible as his actual being makes its way to where his gaze has reached. This is how feats such as the Shukuchi technique were born.
 *  (気周波, Reishūha; literally meaning "Soul Flow"): Invented by Seireitou, which is said to have made his name known throughout the martial arts world, the Spirit Wave is rumored to be the absolute pinnacle of Hakuda that a Grandmaster can reach.

Zanjutsu Master — Way of the Body Sword
Hakuda stands as the center pillar of Seireitou's power. It is through this that he may express his martial art will through various outlets, one of which happens to be the very art of Zanjutsu itself. Just as his martial arts may be focused through the elements around him, such as the air and enemy attacks, by his will as a Grandmaster, the blade itself serves as his "fist"; albeit, a far more refined and precise fist. In doing so, the concept of swordsman and blade are erased as there is only a single existence. Hakuda and Zanjutsu, as per Seireitou's belief, follow the same tenets at their core.

Master of the Sword: In his earlier years, Seireitou was a man that relied on the strength of a blade. Many of the most powerful opponents he had defeated was done so with his sword, such as Utsugi Kururugi and Datara Kawahiru. It has been explained that the art of the blade serves only to "expand" Seireitou's Hakuda. Because Hakuda is the art of one's self and the Zanpakutō itself is part of the martial artist's soul, it stands to reason that a Grandmaster can wield his blade just as he dons his fists, for the sword itself is a part of them, just as their arms and legs are. Hanzei Kurokami stated that a master swordsman of Seireitou's caliber makes his sword a barrier of sorts, subsequently stating the fact that if one were to enter this "barrier", Seireitou would defeat his opponent instantly. However, despite his level of skill, his combat prowess does not change if he should choose to draw his sword, unless he were to invoke his Zanpakutō's powers. This is due in part to the fact that his level of Hakuda is so immense, the art of Zanjutsu does not provide any sort of advantage that was inaccessible to him in Hakuda itself. It was stated by Seireitou that his Zanpakutō serves as a fist, just as his own hands and his Empty Fist martial art does. In other words, the act of using his sword means that he, for whatever possible reason, is seeking an alternate means of combat for the situation at hand. He could also clash against Raian Getsueikirite, a warrior of supposedly greater Zanjutsu prowess than Seireitou himself, forcing both to shift between it and Kidō, among other combat styles, in order to break the stalemate. He is able to fight on-par with Hikaru Kurosaki, a legendary swordsman of vast Zanjutsu technique in his own right, and even slice through his Getsuga Tenshō with strict ease (albeit the technique lacked killer intent). This similar action is preformed various times against many different forms of spiritual attacks, all of which resulted the same way; including that of elemental attacks such as fire. Seireitou is ambidextrous, meaning that he can effectively utilize his sword with either hand and still retain a similar level of strength and ability. Although, he can also shift the strength of each swinging arm, in order to throw off an opponent's initial deductions. He is capable of using his speed for flawless precision and to inflict lethal attacks without much effort. A simple swing of his blade is strong enough to easily cut an opponent, even at a longer distance. Seireitou prefers to wield his sword with his right hand, leaving the other hand free though it usually remains hanging. He is quite adept at blocking while his offense is capable of great precision. Seireitou's general method of sword fighting involves evasion and attacking an opponent either in the front or back using the element of surprise to overwhelm them. He has a tendency to use a "wait-and-see" approach, often countering an opponent with lazy-yet-skilled actions in order to gauge their level of skill and their fighting intent. In other words, Seireitou draws his opponents in, fighting less than his true capability, and then striking the fatal blow when his opponents believe to have the advantage over him. That being said, he is more than capable of ending fights against other skilled opponents in a single move when the moment strikes him. In addition, Seireitou has shown an ability to easily mimic the techniques used by other master-level swordsman with little effort. His unpredictable nature allows him to change his fighting style on a whim so as to keep his opponents unsure as to his next move. Those who witness Seireitou's prowess state that he "carries himself with a certain elegance", possessing skill that can only be identified as that of a master's level, despite not necessarily belonging to any specific school of swordsmanship. Additionally, through training under Dangun, Seireitou had understood the secret of "aiming the katana's will". This method involved being able to cut through steel, by eliminating the ability to cut through anything else. In this regard, one could direct the might of one thousand strikes in a single slash with this method. Similar to that of Hohō and Kidō, Seireitou's knowledge of theory far surpasses his abilities of application, despite how frighteningly powerful his application is. It is his knowledge of theory that is rivaled by Raian Getsueikirite, the Grandmaster of Zanjutsu among the four Yonkō, despite how the latter's application is said to surpass Seireitou's own. Seireitou utilizes a form of footwork that is unlike that seen in most sword fights. While, like Hakuda, he prefers an "off-the-ground" method of fighting, all of his attacks seem to be led by a series of steps in accordance to a pseudo-clairvoyance that was developed during his training with Shōyō in order to avoid the attacks of his opponents by the least possible margin and using the least possible effort in order to place himself in the perfect position to strike in the very instant the opponent's strike misses. Because of this, Seireitou's overall method of swordfighting stresses two-step attacks in order to ensure that any and all who oppose him are thoroughly slain.

Shutōryū (手刀流, literally "Method of the Blade-Hand"): As one that has mastered the body to its peak, it is possible for one of Seireitou's stature to quite literally become a blade itself when fighting. Martial arts themselves manipulate the form in which power is delivered. They determine the method in which strength and power are distributed and manifested, and therefore, a Grandmaster of Hakuda has reached the point where they may control the method itself. In doing so, when they strike and thrust with their body, they do so with the mindset of "cutting". Their attacks are thrown with the intention of slashing the target rather than dealing concussive or projected damage; resulting in quite literally turning their own bodies into swords. When operating under the mindset of behaving as a sword, their bodies reigned in by the force of their will respond appropriately to this change in thought, transforming the body's properties to fit that of a blade; allowing for the skin to become harder than even an Arrancar's when engaging actual blades in combat. It is possible for Seireitou's hand to contend with a swordsman's sharp blade, in the same manner as if he were holding a sword and clashing with said swordsman himself. However, this only becomes possible for as long as he retains the mindset and maintains his will, for if he were to be caught off-guard, no longer would his body be afforded the properties of a blade. Because his body behaves like that of a sword, it is possible for Seireitou to also conduct techniques through his own hands.
 * Shutō: Nadegiri (手刀・撫で斬り, "Blade-Hand: Killing Stroke"): Derived from the technique created by, Seireitou can perform using his own hand rather than that of a sword. By holding his hand upwards, forming the knifehand gesture, he slashes downward and causes everything in his hand's wake to become slashed apart. It is capable of reaching an incredible range, completely slicing apart all things in its path. Comparably, it can also be executed using a kick rather than a hand strike.

Hohō Master — Body and World Communication
Being a master-class fighter, Seireitou has developed immense levels of skill in the field of Hohō. In fact, his skill has grown to a point where it has become one of his more noticeable traits. Even within the use of a technique, Seireitou's immense physical strength coupled with his uniquely-toned musculature allows for his legs to produce instantaneous movement and allows him to react within a split second. Supplemented by his mastery of Seiten Shiranui-ryū, following the nineteen-month timeskip, this allowed him to develop an almost god-like speed, that even Mūkade's strange ability to track speed and movement couldn't keep up.

Shunpō Mastery: Seireitou's skill in Shunpō is so great that it seems as though he possesses a form of teleportation as he moves in the blink of an eye, simply "appearing" solidly instead of shimmering for a second like other Shunpō users. This allows him to move fast enough to easily parry a close-range killing blow by a Captain-level opponent. Seireitou manages to move at exceedingly incredible speeds, quick enough to appear behind Kamui's back and effectively counter him before the former could even turn to face him. He is capable of effortlessly dodging simultaneous attacks at close range and the evasion of Bankai level techniques. He moves so fast that opponents commonly do not know his movements until after he has made them and is skilled enough in his movements to evade at high speeds even when being attacked from behind. Ideally, his motions are far too difficult to predict until after the movement is carried out. During a fight with Raian Getsueikirite and Shinji Hirako in Soul Society, although Seireitou states that Raian's overconfidence and Shinji's weak resolve was impeding their performance, Seireitou was able to easily outmaneuver both opposing Shikai (despite Kagemusha and Sakenade's hypnotic powers) and mask-enhanced speed to the point he could casually lay a finger on Raian's forehead and still dodge a point-blank cero from Shinji, who had his fist against Seireitou's back. By rapidly increasing the speed at which each step is done at exponential levels, the user can move at beyond god-like speeds. Seireitou reveals to have a very fluid mastery of this, shown by his ability to invoke the technique as if it was second nature, despite the tendency for other users to end up with their legs broken due to inexperience. A master of Shunpō, such as Seireitou, can easily match and possibly surpass the speed associated with Shunkō, making it one of Seireitou's trump cards when all else fails. These rapidly-increasing steps cause multiple sounds to occur, in contrast to the regular use of Shunpō which produces a single light sound. Substances beneath him, such as tatami mats, appear to explode with each of his steps. In some cases, one can produce a spark of spiritual energy, similar to that of a Fullbringer's Bringer Light, and even burn the ground beneath him with each step. This is because, in Shunpō, the user exerts a stress-induced force on their legs just once, and then uses their spiritual energy to accelerate their movement without the need for further force. However, by accelerating the steps, force is exerted with each step, and with each step, more and more stress is exerted on the legs while using their spiritual energy to accelerate at god-like speeds. The mastery of Shunpō has enabled Seireitou to learn various techniques that are mastered only by the Shinigami elite of the Gotei 13. Although he has studied primarily in Shinigami combat, Seireitou has taken to studying the technique, advantages, and flaws of various other speed enhancement techniques, despite not being able to preform them himself. This knowledge has led to the creation of master-level Hohō techniques that are unique to Seireitou alone. Most specifically, he has studied the Quincy technique,. He has an interest in how they use their manipulation of reishi that allows them to "glide" rather than "step" when moving, and when faced against master-class opponents, adopts his movements to Quincy-style technique. In one instance, Andreas Nikolai noted that Seireitou was "moving less like a Shinigami and more like a Quincy". It is through such an action that he has essentially achieved a "constant Shunpō", as coined by Raian, which allows him to "glide" with his movements instead of having to step, as demands the style of Shunpō. However, most noticeably, when the technique is initiated, it almost appears as though Seireitou has disappeared, fading away when he begins the movement. This is due to him entering an opponent's blind angles, making it near impossible to register him via eyesight. Although he is much too fast to spot, even through the trained eyes of Dante, the brief moments where his presence is visible, it is noticed by few that a spark of white light is generated at his feet. It is presumed that he uses that aforementioned cycle of spiritual energy to essentially "skate" through the "clouds of reishi" around him, while coupled with various acts of acrobatics, makes his movement impossible for even other master-class Hohō users to keep up with him or even make contact. In addition, Seireitou claims that this manner of movement makes his center of gravity an illusion, a claim which was proven in the former's fight with Kyebaek Tae.

Hyper-Speed Combat: Through the application of Hohō through Hakuda, Seireitou's body movements appear as mere blurs, if anything else. With his arsenal of kicks, strikes, punches, and throws, Seireitou's speed at the utilization of these aforementioned techniques is nearly god-like. Most opponents are unaware that Seireitou had carried out his technique until they become aware of the damage that he has wrecked upon them. Because of this, Seireitou's Hakuda speed allows him to even take on users of Bankai one-on-one, while still appearing to have the advantage. The speed at which Seireitou attacks is unprecedented, as a single punch from the viewpoint of any other opponent can conceal nearly a hundred hand strikes simultaneously. With incredibly agile and quick footwork, contending with Seireitou in any form of hand-to-hand combat is usually a short bout in which the challenger is utterly overwhelmed and defeated. This sort of speed is very useful against multiple opponents, allowing Seireitou to effortlessly wipe out a battalion of warriors in no more than a split second.

Shukuchi (縮地, Reduced Earth): Upon reaching Hakuda's pinnacle precipice, one comes to fully understand their existence and attains a centered undisturbed tranquility. They may see the world for what it truly is: a flow of energy, making various twists and turns, at a medley of angles and rhythms. Essentially, one realizes that life is in a constant state of unyielding motion. In doing so, it becomes possible to enter this flow and "ride" it to one's location instantaneously. This is known as the art of reducing earth, the Shukuchi, a technique regarded in legend by the Kami who first utilized its ability; as achieved through the skill of a Hakudaka of Seireitou's prowess. As though one were swimming down a river, Seireitou can transition between two points of space by riding the world's own energy flow. Theoretically, it is possible for him to close the distance no matter what restrictions may be in place, whether they be of the physical or even spiritual variety. For combat purposes, the Maai, the distance between two opponents, is known as the physical personification of this flow. Seireitou can immediately close this space between himself and his opponent(s) in battle. Nothing appears possible to hinder the Shukuchi's motion; distance itself is of no consequence to this technique, as even massive distances of spacial separation are nothing to this technique. The benefit of this motion technique is that distance can be crossed with excluding time itself as a factor. Ichigo Kurosaki, when brought to another location by Seireitou via the Shukuchi technique, described the experience as such. Within a split-second, the two of them arrived in a barren wasteland, far away from the grassy knolls where Ichigo could see the sekki-seki castle known as Seireitei; where he had just stood not even a second before this change of scenery. Though, the transition felt... weird. The moment he had realized Seireitou touched him, his vision was quickly blinded by what appeared to be a river of various colors; some he knew and some he hadn't ever laid eyes upon before. It has seemed as though they were swimming in this river of colors, but before he comprehended such a thing, they had arrived in their destination. A strange feeling indeed... It was no flash step that the silver-haired man had just used to bring them to their location. It was more like... teleportation than anything else. Whether a vast distance or even a short one, time becomes nonexistant as the distance is crossed instantaneously. Sōkudo had believed that the Shukuchi allows Seireitou to move from one point in space to another point in space while remaining within the exact same time-frame, making both distance and speed negligible. The technique reveals to possess the ability to even allow Seireitou to escape Sōkudo's space-time techniques generated by the Kuro no Hōgyoku, despite the latter already being in physical contact with him. Even when he is in contact with another person or object, he is still able to utilize the technique and, if he so wishes, can teleport other objects as well. It goes without saying that the technique completely surpasses any form of Hohō, as it is a manipulation of time and space through the martial will of Seireitou's Hakuda rather than accelerated movement.
 * Yanagi Hayurashi (柳葉逍遥, Willow Leaf Walk): Not Yet Revealed
 * Quánlùshù (全路術 (クォンルーシュ), Kuonrūshu; Chinese for "All Paths Method") is an ancient martial art that only those that have reached the "precipice" can possibly learn and master. When examining the world of reishi at the most smallest level possible, one views a realm of vast unpredictability and utter chaos, in which all possibilities that could exist, can exist in some way or form; should it mean that these occur within the same existence or in alternate dimensions. When certain circumstances happen in one's life and lead to particular events, in the way that causality explains the world operates, other possible outcomes and scenarios either do not occur or happen in other dimensions that escape one's limited perceptions. However, this is overcome by the select those that have reached the precipice that transcends the physical and even spiritual chains that bind understanding, allowing them to perceive the "world's flow". This is something that allows one to actually view causality in its purest form and actually manipulate it to a degree. It is said that the first one to reach this level was the founder of Quánlùshù, an art that makes it possible to manifest all possibilities within a causality relationship. Seireitou, as one of the only existing martial artist aware of this art, has revealed himself to have mastered it in its entirety; although it is almost never used by him in normal confrontations. He has demonstrated the ability to effortlessly manifest multiple potential responses for all situations simultaneously, as per the martial art's purpose. This is due to the fact that Seireitou is freely capable of perceiving the "world's flow", making it possible to read the causality relationship for an event and respond accordingly via the Quánlùshù. He can "dodge an attack" while also "doing nothing" with such ease that a physical strike would appear as though it has merely passed through him. However, he can take it much farther than just this simple expression of the art. The mere act of this style is the idea of transcending the physics of a world. In purely offensive terms, Seireitou can even preform several concurrent attacks in order to close in on a target from all sides so as to imprison them and leave them without any means of defense nor escape; applicable to even the most basic of techniques and normal combinations. It completely disregards space and time, going beyond all physical limitations such as speed and other associated factors in order to carry out the technique. The Quánlùshù is a complex martial art and despite its nearly limitless possibilities, Seireitou is acclaimed to be capable of using any and all of them.


 * Banshō Kyōkuha Nukite (万象杏都ハ貫手, "All-Covering Ultimate Destruction Crossbeam Hand"): Not Yet Revealed

Kidō Master — Personifying the Spell
Many often remark that there exists only two true combat styles. Reijutsu, the spiritual arts, and Taijutsu, the physical arts. In order to maintain consistency with his strengths, the greatest of which is Hakuda, Seireitou had managed to turn his use of Kidō into another outlet of his martial arts; a skill he developed through studying the other fighting styles in Yāolù. It is often considered a "last resort" maneuver in combat, prior to using his Zanpakutō's powers, as Seireitou prefers to settle one-on-one disputes through direct Hakuda, but will invoke Kidō against multiple opponents. Seireitou's general ability in Kidō places him right on the borderline of master-class. He is well-versed in both forms of Kidō: Hadō, the offensive nature, and Bakudō, the defensive nature.

Will of Reishi — Following the Old Master: Spellcasting is the act of expressing the "will of the spell" or rather the "will of nature", as Seireitou explains and Kamui himself confirms, in which the sorcerer calls forth the power of another force through their own will. Those that have mastered the art of Kidō, as it was meant to be mastered, learn to draw upon the fragmented wills that compose the around them; conflicting and competing wills, full of their own desires and intentions, all of whom become subservient to the Kidō Master's will in order for a spell to be formed. But this is only true in the case of one that has pursued the studies and mastery of Kidō as a craft. While all spell masters have different motivations and emotional guidance that allow for them to control the reishi around them in order to perform a spell, it all boils down to sovereignty; the master's will must be stronger and far more resolute than the collective wills he is calling forth, otherwise, the spell will backfire and explode in the castor's face, due to the conflict within. But as a martial arts master, one that has guided so many young souls in his lifetime, Seireitou's method of calming the conflict between wills is done with a different approach. It is not a matter of becoming stronger than the amalgamation of wills and spirits gathered together into the spell but rather giving them a leader that they can rally behind; a teacher they can put their faith in as they pursue perfection. Rather than merely calling forth the spell, as other castors do, Seireitou allows himself to become the vessel for which the spell can come about. These souls, afraid and angry, proud and vain, desperate and ambitious, are lost lambs in need of guidance. Treacherous Kidō Masters take advantage of their fragility and claim hold of them through their own strong will, in order to strike down their foes through the magical arts. But Seireitou, the wizened yet wise master of martial arts, can provide them what they truly desire. This is essentially an extension of Katsujinken teachings, in which one attempts to understand the adversary rather than simply aim to strike them down. Regardless of the desire, no matter what the task might be or the truth behind their raison d'être, all things can be accomplished through the martial arts. But they must give themselves to the teacher, the master of unquestionable wisdom and ability, and in doing so, becoming students of martial arts themselves that may now serve their master, just as it was in the old days. It is an ancient idiom that the true character of an individual will come about as a product of martial arts; no matter how vain or egotistical, conceited and enraged, they might be at the world or at others, their hunger for satisfaction will be appeased in a way they never thought possible. This isn't the silky words of a crafty manipulator, full of empty and selfish promises, but the honest understanding that comes from viewing a world one never thought possible because they had followed a true teacher that seeks only to show them a world of peace. In doing so, the fragmented wills of reishi, once conflicted and in a state of war, now find a semblance of prosperity as a student of Master Seireitou; and thus, the spell is born as an extension — nay, a manifestation of Seireitou himself, which surrounds his very body and composes his very being. Kidō Masters can try their best to seize command of the spell after Seireitou has become one with it, but they would find their efforts to be futile. Those that attempt to take command of the conflict between wills and guide them in the formation of the spell would find it impossible to overwhelm Seireitou's will, as these fragments follow the latter as disciples follow their beloved master; to turn these wills on their own teacher, that have entrusted their hearts to him, is simply an impossibility so long as they remain close to their master. Under Seireitou, they find both strength and satisfaction, both shelter and meaning — they have found their place to belong. And they will not allow any outsider to take that away from them.

Spellcasting — Students of Master Seireitou: Just as the students that follow their master, learning the martial arts and the ways of life itself, the reishi gathered together by Seireitou to perform follows the same paradigm. After showing these fragmented wills the proper way, as a true teacher, his reishi serves as the core in which these reishi gather together to join their master in triumph. They surround their master and are prepared to fight together with him, as part of him, rather than as cold instruments of violence. When this action has been accomplished, Seireitou adorns a shroud of the designated spell and he is subsequently granted with special effects that are associated with the spell's original purpose. This is considered a "step beyond " in that Seireitou is not driving Kidō into his body but rather his reishi itself is serving as the core for the spell to take shape and be born; essentially transforming the silver-haired man into the spell itself. When shrouding himself in Shakkahō, he accents his fighting style with an intense burning aura. Covering himself in Dankū would bestow upon him a certain degree of magical protection. The possibilities are quite endless. In a similar vein, he can even produce clones of himself through these spells, allowing them to move freely from his body through his will like a sort of silhouette, forming solid clones that take on the properties of the spell itself. In addition to the shroud, just as the force of his punches can transcend distance as shockwaves, so too can be unleash magical power as though he were throwing a punch. Because of this, Seireitou is capable of unleashing wave after wave of spells without needing time in between. Seireitou's use of Bakudō is surprisingly high, capable of generating even a spell of Dankū almost instantaneously without incantation. He is versed in a medley of Kidō spells that often escape the broad classifications of Hadō and Bakudō, some of which are unheard of by those under the expert class. Seireitou was also capable of using a form of teleportation that Shiori Miyamoto, as proficient as she is, hadn't known existed. He is also able to use this ability to completely hide his presence and spiritual energy, as not to be tracked. Seireitou does seem to have some competency with Kaidō, the faction of healing spells, though just enough to administer first aid or to heal injuries that had been inflicted within a certain time frame. His understanding of the advanced mechanics that go into the arrangement of spiritual energy allow him to effortlessly understand almost any type of Kidō spell, even if it is a spell that he has never seen before. Since he treats Kidō as a part of himself, like that of Hakuda, he often changes the conventional shape of well-known spells to enforce this point. Examples of this include turning Sōkatsui into a flurry of fist-shaped projectiles, expelling a Haien as though he were throwing forth an Ikkotsu, producing a wide-spread Ōkasen that snaps outwards as a roundhouse kick, and making Sajō Sabaku act as a Jujutsu hold, stressing vital spots on a victim to ensure capture; among many other endless applications. Despite changing the shape and form of these spells to better reflect Hakuda, the effects that each unique Kidō possesses are still retained completely. Tadoku Getsueikirite was the one to coin the skill as "martial arts spellcasting". One of the most prominent methods of this skill is through integrating them into his Hakuda stances. He is able to apply particular Kidō techniques (along with a myriad of other obscure spells) to supplement and benefit his Hakuda techniques and stances, such as using altered Seki spells to surround his fists in energy-composed tekkō, allowing him to combat an opponent's own spiritual attacks (including that of other Kidō) with his bare hands while stunning any opponent struck by his physical strikes.

 (気流掌握, literally "Holding onto the Flowing Spirit")


 * : When taking on the shroud of the thirty-first, known as Shakkahō, his body becomes a powerful embodiment of red flames that are capable of inflicting grievous burns that are carried through with his martial arts. Because of the powerful aura emanating from his flame-merged body, the flames of the Shakkahō follow the arc of his body movements and techniques. It is therefore common for him to utilize hard-type martial arts exclusively when using this spell shroud, for fire is an aggressive force that is meant solely for destruction; he is often known to exercise Hung Ga and Heihuquan styles primarily. When combined with his Hakuda, he is capable of performing tremendous stunts that only a combination of these two disciplines would be capable of bringing about. Seireitou can curl up his fist and thrust it outwards in the same manner as he would execute ; mirroring the intent of the Hakuda technique. Unlike the flashiness of a traditional Kidō Master's use of the spell, the Ikkotsu-directed Shakkahō manifests as a narrow and refined lance of red flames that is released from Seireitou's fist like a fiery spear that seeks to burn through its target with a singular purpose in mind. At the instant it pierces the target, it immediately combusts and engulfs the target in an intense flame, devouring them until nothing remains. Similarly, the can also be performed in this manner; albeit, with a far more chaotic impact. When executed, it manifests as a pair of fiery lances that, due to their close proximity, share heat between each other through minuscule channels though they were two mighty rivers with several streams interlocking the two together. Once the pair hit their mark, the resultant explosion causes a growing surge of fire, expanding from the point of impact, which proceeds to absolutely incinerate the target and rendering them onto ashes.
 * : By shrouding himself in the spell, Hyōga Seiran, he takes on a chilling light blue aura that causes a dramatic decrease in temperature in the space around him as well as his own internal temperature itself. Seireitou claims to have been able to produce this shroud after closely studying the technique of the . While not often considered his favorite shroud to use, especially due to the level of difficulty that comes with performing it and the danger that arises from not being in the entire time — for it is possible for him to end up freezing himself to death — it does appear to grant him invaluable uses in combat. In particular, he is known to channel the spell shroud through, allowing his conceptually created appendages to physically manifest as a massive ice structure that can restrain an opponent by freezing them; perhaps even to the point of their defeat. Seireitou is known to employ the use of both Tàijíquán and Bāguàzhǎng when using the shroud offensively but also defensively.
 * : Perhaps the most powerful shroud that Seireitou is capable of adorning, he can take on the power of the ninetieth Hadō, Kurohitsugi, which bestows upon him with a dense black and purple cloak possessing an immense torrential pressure that encompasses his being as a pure embodiment of gravity. When combined with his Hakuda, that already is capable of producing distortion effects onto the world, the force has reached a point of perfection that Seireitou's strikes can clearly smash straight through spacetime and subsequently create dimensional portals in the wake of the attack. Unlike the elegant motions of the auras produced by his elemental shrouds, the Kurohitsugi spell is one of precision and absolute force. Therefore, it goes without saying that only a straightforward method will be fitting to harness such power, prompting Seireitou to invoke the essence of Karate when executing strikes through this spell shroud; a martial art that abandons flashiness and dance-like maneuvers in order for the artist to devote their entire being into the strike. With a swipe of his arm, a massive crescent-shaped is projected outward where the force of the strike was intended to reach, slashing apart whatever lay within the vicinity while swallowing up the remnants into the . When a punch is executed, the force is projected at incredible speeds, like a flash of light itself, smashing into the intended target and forming the opening in spacetime. Victims that are struck by Seireitou's punch while empowered by this shroud will find it impossible to escape its grasps, for they have already been ensnared in its invincible might. However, with such divine power, comes an equally heavy cost. It goes without saying that immense concentration is needed to maintain a spell shroud of this level, to the point that even one of Seireitou's skill can only maintain it for a certain period; whereas other spell shrouds, like the Byakurai or the Shakkahō, can be maintained almost indefinitely. However, because of the immense gravitational force associated with this spell's core technique, it is normally considered an impossible feat for any individual to actually dress themselves with a spell of this caliber. It is only because of Seireitou's unrivaled degree of self-control and physical strength, acquired through his absolute mastery of the martial arts, that it is even possible for him to use such a spell without succumbing to his knees as a broken pile of shattered bones. That being said, however, all beings have their breaking point. And for Seireitou, he is no different. Even with total concentration, this spell shroud can not be wielded for too long at a single time and reused without a proper recharge period, due to the level of pressure being inflicted onto the man's body when adorning this cloak of gravity.


 * : Shrouding himself in the sixty-third spell, Sajō Sabaku, several bright golden chains materialize around his being in all manner of formation; it is possible for them to manifest as multiple individual chains appearing from certain places of his body or even as a sphere of linked chains that surrounds Seireitou which can be broken off and manipulated freely, though there are countless possibilities. The most basic expression appears to be using the spell as whips that are extensions of his body and follow his movements, more particularly working best when directed by the art of Tàijíquán. However, the most fearsome aspect of the Sajō Sabaku Shroud is that Seireitou utilizes the spell as though he were utilizing a joint hold or lock against his enemy, directing the chains like that of additional arms, but also serve to empower and enhance styles such as the . These chains originally served the purpose of surrounding an opponent and then ensnaring them, stripping away freedom of movement. but these chains when directed by the Hōkōryū merely encircle their target and then levitate in place around them. Once doing so, these chains began to lose their golden glow slowly, being replaced by an eerily silver glow as their previously gold light was fully extinguished. In this sense, the technique instead serves to interfere with the victim's mind and will rather than trying to physically restrain them, serving to temporarily negate much of what they can do against him.
 * : Though not meant for actual combat, this is a shroud of the seventy-fifth Bakudō spell, Gochūtekkan. According to Seireitou, the purpose of the Gochūtekkan, from which it derives its use as a spell of binding, is that it uses weight to subdue an opponent. The higher the skill of the user, the more heavy they are able to create the five pillars forged from this spell. As a shroud, the result is that Seireitou is surrounded in a pale silvery aura which causes his weight to drastically increase in accordance with his whim. Though this serves almost no use in combat, this is a shroud used commonly when training his students; as part of their physical endurance training, they are expected to run several laps while having to pull a cart with no wheels, connected via a rope tied around their waist, with Seireitou sitting crossed knees within it. The shroud allows him to increase his weight as he deems fit to further increase the difficulty and efficiency of this training.

Ura Hadō (裏破道, literally meaning "Hidden within the Palm, Way of Destruction") are a specialized form of spells that are cast with the intent of mirroring one's  styles. It is said to be the ancestor to the battle technique. In the vast history of martial arts, man had long studied and mimicked animals and even the movements of nature itself in the hopes of acquiring strength from those observations. The original arts were derived from animal behavior and progressed onto the art forms that exist today. One may eventually hope to master the martial arts to such a degree that their movements become undistinguished from an actual beast, a threshold of skill that Seireitou himself had reached long ago. The Ura Hadō method allows for one to further this mimicry to another step, using through spellcasting and then merging with the spell to allow the nature of one's martial art to be reflected; in other words, the hidden meaning of a martial art can arise to the surface and manifest onto the outside through Kidō, hence the purpose of the term Ura Hadō, which translates into "hidden Hadō" in the sense that its true meaning is hidden within and disguised. Just as the arts had changed over the ages from the original mimicry of the animals in nature, Ura Hadō reveals those natures hidden within the Hakuda and surrounds Seireitou's body in a powerful spell that reflects those characteristics. Similar to before, when Seireitou was merging together with the spell and the reishi which composed it, Ura Hadō goes a step further and breathes new life into the martial art. In doing so, no longer is the martial arts master mimicking the animals, but rather, they are now transcending the physical beasts themselves.

Kitsune Lineage
As a Sōzōshin-born Kitsune, Seireitou is most commonly seen in his human-like form, despite the fact that the abilities of a Kitsune still present themselves in this aforementioned state through his Hakuda capabilities. However, he can take on his true form as a Kitsune upon personal preference, allowing him to achieve his truest power. In doing so, his hair lengthens and becomes far more untamed, with a pair of fox ears forming at the top of his head. Seireitou's eyes becoming a piercing yellow in contrast to the calm amber they originally were, while exerting an intense foreboding gaze from them, much like that of a predator seeking its kill. He is classified as a Kyūbi (九尾, "Nine-Tails"), and thus, nine magnificent white fox tails form behind him, completing his transformation.

Complete Transformation: Seireitou is capable of shape-shifting into a white fox with red markings at will, similar to the feline transformation utilized by Yoruichi Shihōin. However, unlike Yoruichi's transformation, Seireitou doesn't appear to be the same size as a standard fox would be, but rather large enough to allow another person to sit atop his back. In fox form, Seireitou can still channel his spiritual energy and move at incredible speeds, and due to his more agile frame, his speed allows him to move across narrow spaces that would be considered impossible in his real form. Speed-wise, he isn't restricted in the same manner that Yoruichi is in her cat form, but in fact, his speed is even greater. However, the trade-off is that his strength is hindered. His transformation also allows him a complete disguise, completely shrouding his spiritual energy signature. However, as demonstrated by Kamui, a master of Getsudō, it is possible to still distinguish his presence, even while in fox form.

Zanpakutō
For the manifested spirit of Hanullim, see Hanullim (spirit). Hanullim (하늘님 (魂元), Hanūrimu; Korean for "Source of all Being", Japanese for "Lord over all Skies"): The manifestation of his Sōzōshin powers as well as his status as a Kitsune, Seireitou's is regarded in the history of  as one of the most powerful among all other Zanpakutō yet also its most malicious; a fitting blade for the man renowned in legend as the White Demon that struck fear in the hearts of his enemies. Even when it would remain in its sealed form, a powerful aura of pure intent surrounds the Zanpakutō which tends to fluctuate in its nature. Its power is respected so highly that most opponents fear its strength; to such a point that legions of enemy forces would actually retreat when hearing its release command. In his younger days, Hanullim took on the form of a nōdachi in its sealed state; possessing a white hilt sporting unique complex shapes on it. The top edge of the nōdachi possessed interesting kanji, which Seireitou had once claimed represented the four souls of the Shinto philosophy of Naobi (直霊): Aramitama (荒魂, Courage), Nigimitama (和魂, Friendship), Kushimitama (奇魂, Wisdom) and Sakimitama (幸魂, Love). The meaning of the symbols lies in the Shinto belief that when all four of these traits are united in one person, they unite to form a powerful balance within the soul that can be used for good or evil. Due to the incredible extent of Seireitou's mastery, he is capable of utilizing Hanullim in a sealed state in which it appears to be in its released state as a pair of tekkō. The same four markings present in the Zanpakutō's original blade state are also inscribed onto both of the tekkō pairs. This is often preferred by him as a manner of convenience, as he rarely requires the need to engage an opponent in swordsmanship, given that any Zanjutsu technique can be replicated and perhaps even improved upon through his Hakuda.

The spirit of Hanullim, when materialized, possesses a strikingly similar appearance to that of his own master. He has long silver hair, kept in a knot, and also bears red markings on his cheeks as well as faint red eye shadow. Characteristic of a kitsune spirit, his ears are rather sharp and pointy and he has striking yellow eyes. Hanullim dons a bright white kimono with blue formal attire underneath. Of course, this is not his true form. Within Seireitou, he exists as himself; a massive white fox with nine tails. Existing as a dangerous spirit bearing incredible powers, with an equal sense of deception and a penchant for mischief, the Hanullim is quite unique if only due to its legendary temperament. Of course, like all other Zanpakutō, Hanullim also has a personality of his own, but unlike those others, this personality shines through in battle and prevents Seireitou from fighting with its full power until Hanullim is in the mood for it. Because of this, Seireitou considers it a "pain in the ass" to work with "him". In light of its rather moody disposition, Hanullim does demonstrate a rather impressive intelligence while portraying himself as wise when the situation calls for it; displaying a true kitsune's great intuition and instantly seeing the truth no matter what deception lay before him.

Shikai
When Seireitou had first awakened his Zanpakutō into the Shikai state, it was released by the command, "Radiance of redemption that leads us to sunrise. Let hallowed prayers be spoken ever more!" (黎明へと導く覇者の煌たまえ聖なる祈り永久に紡がれん, Reimei e to michibiku haja no kirameki yo. Seinaru inori, tōwa ni tsumugaren!). When releasing his Zanpakutō during his days as a Captain, he would hold it out in an outstretched arm in front of him with the blade pointing down and declares the release command. Hanullim would form into a sleek, medium long-sized sword. The grip had a gentle decorative hand bended forward at the end with a white tassel dangling from the pommel. Instead of a cross guard, there was a dark gold U-shaped decoration that covered the first three inches of blade, with a flower petal design just as it met a black string wrapping. At where the decoration made its curve, on both sides, the kanji for "yin" (陰) was depicted on one side while the kanji for "yang" (陽) was on the other side. The string was wrapped thrice around the hilt, with a three-loop bow on one side and a decoration on the other that consisted of connected crescent yin and yang components, connected to one another, crescent point-to-point. Hanullim's blade was shown at this time to be a very light gold with a silver-edge. It was also straight and slim, with the tip having ended in a slanted razor-like edge instead of being tapered to a point.

This was how Hanullim presented itself over a thousand years ago. But just as he himself changed throughout the millennium he spent following his defection from the seat of Captain, having acquired an unrivaled mastery of, his Zanpakutō would reflect the change in his soul. Rather than a blade, Hanullim's sealed form would consist of a pair of black tekkō arm protectors which are worn almost consistently and can normally be hidden somewhat under his bell-shaped sleeves. It is unknown if the same release command was utilized, but given the silver-haired man's mastery, it is simply unneeded; all he must do is will the sword into activation. The arm guards would lose their blackness and become a pure white; reflecting Seireitou's spiritual power coloration. Hanullim's release comes with an extreme release of spiritual pressure affecting all in the area, and can be felt for miles upon miles across all of Seireitei.

Hanullim is a very malicious and deceptive Zanpakutō, a direct consequence to Seireitou's own chaotic nature as a person, often lying and exaggerating about certain things; making it a very troublesome sword to work with. The latter had concomitantly stated that Hanullim is also very lazy and that it takes a "significant level of motivation" to make the Zanpakutō awaken, meaning that even when released into its Shikai and Bankai states, very little of its power can ever be accessed at a given time unless Hanullim himself appears to be "in the mood" for it. However, the true danger in the sword's mischievous nature is that the forces it can manifest are not simply changing the world around it but also influencing its master, Seireitou, every single time the sword's power is accessed. While there appears to be some level of control over this, due to Seireitou's vast centuries of experience and expertise with using Hanullim, the latter has had a very significant effect on its master. It has been stated that it was due to Hanullim's inference with Seireitou's instinctive subconscious and aware consciousness that led to the birth of the latter's Shiroyasha persona, and that consistent use of the Zanpakutō's abilities would prompt the Shiroyasha persona to arise within Seireitou; emphasized by a far higher degree during the use of Bankai. In order to prevent such a disaster from occurring, Seireitou took to training in Hakuda and subsequent disciplines, therefore prompting him to forgo the need for Hanullim's powers. The result of this not only made it so Hanullim would not be necessary to handle most opponents but also provided Seireitou with a level of self-control that can keep the harmful effects of Hanullim's power from affecting him to any further degrees when the sword's power is in use.


 * Aggressive Hanullim (仇魂元, Kyū Hanūrimu; literally "Passionate Source of all Being"): Reflective of Hanullim's mood, when the kitsune spirit possesses an angry or excited sort of attitude, it manages to bring forth white flames that serve as the personification of his passion. Torrents of magnificent white flames are unleashed from Seireitou that bear an immense intensity that can seemingly destroy any adversary that lay in its path. These flames are remarked as being powerful enough, at the height of Hanullim's anger, to be capable of rivaling the Sōkyoku. Thus, the potency of these white flames are directly correlated to the degree of the strength of Hanullim's emotional state. Though the flame's potency are dependent upon Hanullim, Seireitou is capable of influencing them to some degree with his interactions with his Zanpakutō. These white flames can ideally vaporize a victim's soul when consumed by the blaze, with its offensive and defensive power said to be equivalent to that of a hundred Zanpakutō when its true might is mastered. Additionally, this power increases by tenfold upon piercing through the target; just as anger itself is an emotion that incites rage in the souls of others in its presence. Despite the explosive capabilities, Seireitou can also do pinpoint aiming, as shown when he was able to instantly burn up only Qiongqi's arm and left the rest of her body intact. Seireitou can simultaneously alter the method of how he projects Hanullim's flames, first to instantaneously boil the liquid in Taotie's eyes, causing excruciating pain with pinpoint aiming, followed by a wave to engulf the latter in a large blaze to incinerate what remained. What makes these flames unique is that, similar to how normal flames feed on oxygen in the living world, these flames feed on and  in the exact same manner, growing stronger and fiercer the more they feed upon as they consume all spiritual sources until everything is rendered onto nothingness. These flame emit a heat that can completely evaporate even a being of considerable spiritual power, seeking to literally burn them until nothing of them remains, not even their soul, meaning those killed by Hanullim's wrathful flames have no hope of ever reincarnating. It is akin to how a Quincy kills their target. Koga Tensei called it the act of "burning the soul away".


 * Projectile Blade Creation


 * Tenchi Kaijin (天地灰尽, "Heaven and Earth End in Ashes"): Not Yet Revealed


 * Hitenmai (火天舞, "Dancing with Heavenly Fire"): When in use, an immense burning aura of white flames surrounds Seireitou which, when directed by his hands, can disintegrate nearly anything, reducing it into nothing more than ash. It has the additional effect of engulfing the surrounding landscape in white flames. Only powerful fighters such as Jūsuke Kannogi and Méi-Fēng can resist it, but even then only indirectly. It's power is enough to fight against the force of several Captains simultaneously. Though boasting unavoidability, the white flames has been avoided a few times, such as in the fight against Kamui. The determining factors seem to be motivation and skill. Seireitou's control over the white flames allows him to develop defensive variants of this technique. He has shown use of the technique by enveloping himself in a white flame aura, allowing his flight and movement to seemingly become more destructive, as he is capable of spreading his flames as he moves forward, becoming an "unstoppable spreading flame" as Kintarō Hijikata noted. By surrounding himself in the flames, he could provide an ultimate defense. As these flames are part of him, he may manipulate them via mental thought or even by directing their movement with his hands. By clapping together his hands, for instance, the flames form a large barrier of white flames that surround a number of selected targets, designated for the purpose of trapping opponents for long periods of time. Nothing much is known about the limits of its defensive power, though it possesses a rather immense duration and durability. It appears to act on its own accord, manipulating its own fire in order to ensure that its prisoners remain within its confines, even if means destroying them outright. However, it seems that if Seireitou is within range of the technique, he can mentally control its actions. By summoning these white flames in a different location, he can effortlessly shift himself to another location, in a manner akin to that of teleportation. Seireitou often uses this technique as a means of presenting his arrival to his opponents to grand effect. He is also able to use the white flames to displace his being when he is struck by a physical attack, essentially forming white flames out of any situation. These are, but, trivial uses of this power however. Seireitou can surround himself in a large pillar of these flames as well, similar to how the Vandenreich use Heiliges Feuer in the same way. In addition to the damage it can inflict, this has the psychological effect of causing enemies to hesitate to attack him.

Bankai
Shinwaryeok Hanullim (신와참하늘님 (真如天実), Shinuwarioku Hanūrimu; Korean and Japanese for "Absolute Sovereign Source over all Being"): When Seireitou initiates the Bankai release, he will glow with an intense yet fading white aura that outlines his body. Upon calling out his Bankai, Seireitou's body seemingly turns into white flames that combust, exploding outwards in an enormous explosion of white and black reiryoku whips, that finally fall to the ground as a thick dense rain of reiatsu all over the surrounding area. In this form, Seireitou takes on physical properties of Shinwaryeok Hanullim's inner spirit. His hair becomes more longer and flowing, with a dark red facelines running down the length of his face from both of his eyes, very similar in appearance to that of Ulquiorra Cifer's second release form. The hakama he normally wears does not appear to change whatsoever, though appears a bit darker in coloration, as his shihakushō takes on a more similar appearance to Hanullim's inner spirit. However, it appears to retain the lines present in his base uniform, though thinner and two grey bars instead of one solid black bar. He appears almost royal in his attire, his sleeves appearing to be bell-shaped with the addition of a gold bar running around the edge of the sleeve in a circular fashion. Seireitou's shoulders are draped in a see-through lavender veil, almost reminiscent in appearance to what the traditional mantle that Quincy would once wear. When truly enraged in his Bankai form, his eyes take the most dramatic change, as they appear to become a strange mystical white, with a shadowy black outline. The physical form of Seireitou's Zanpakutō remains very similar to his sealed state, becoming more of a japanese longblade daitō with jagged edges along the design of the blade. It also appears that the hilt has a white chain connected from the bottom of it, running down as it eventually reaches around his waist. The blade itself is durable enough to withstand several of Kamui's Bankai-enhanced Cero and even endure direct hits from Mūkade's massive Bankai. In both cases, the blade did not show any signs of damage. The blade has become dangerous enough to cause aggravated injuries in one single blow. Seireitou tends to loathe using his Bankai, going as far as to call it his "pain-in-the-ass Bankai release." After he had obtained mastery of his Bankai, following a fight with a much stronger Kamui, the form of the Bankai changed ever so slightly to form a white aura around his waist, which manifests as a furry long spiritual kitsune tail in the back, completely white with a black fiery tip. It appears that this tail serves as an indication of the level of spirit energy that Seireitou is utilizing at any given time. As a result, when the Bankai form is initially entered, he only has one tail, but can actually form up to nine white fox tails, an indication that he is using his Bankai at maximum power. Because of his acquired mastery, Seireitou can deem whether to dematerialize his Zanpakutō's blade form or to continue wielding it (when the former occurs, he can choose to rematerialize the blade), allowing him to fight with his sword and hand-to-hand whilst in Bankai, depending on the situation.

While Hanullim's power deals in manipulating and creating interactions of multiple types within the field of Seireitou's reiatsu, in Bankai, all interactions generated and operated by the Zanpakutō are focused onto Seireitou's being and his blade. They are compressed within him, in a way that Shinwaryeok Hanullim allows for Seireitou to "command all interactions by his own hand". Thusly, it is a Bankai that incorporates the interactions that Hanullim can influence within the blade. He can cause existences (whether they be made up of reishi or atoms) or forces to negate one another, repel them from eachother, and even fuse them together into one. In these aforementioned scenarios, the repulsion is often accompanied by an intense burst of what appears to be his signature white flames but rather is his immensely powerful spiritual pressure that gives off such an appearance. These are, as the Bankai spirit claims, mere examples of the fullest capabilities Shinwaryeok Hanullim possesses. Though the power of his Bankai goes far more deeper than simple "cause-and-effect" control, the true strength of Shinwaryeok Hanullim lies in the potential of interactions Seireitou is currently capable of utilizing whilst in his Bankai form. Over a significant period of exposure, even Soul Society can fall victim to its power and be destroyed. Even the Ōin, which grants its master the power of dimensional control, is said to pale in comparison to the devastating applications of Shinwaryeok Hanullim.


 * Power Augmentation: The full extent of his powers are still unknown but he managed to quickly overpower Hibiki Asakura in his Bankai form, despite not initially standing any possible chance against him prior to entering Bankai. Having mastered his Bankai, Seireitou's power reaches the prime factor increase of ten times that of his base spiritual energy level.
 * Overwhelming Spiritual Power: The spiritual energy and pressure of this form is simply unimaginable, as Seireitou's already immense spiritual power is significantly increased further upon entering his Bankai. Just his presence in this stage is so devastating, that he needs to hold back the full might of his reiatsu as so not to kill his allies. When using Bankai, Seireitou's reiatsu takes the shape of several black and white reiatsu wisps surrounding his body, as well as a large aura that rains down on the opponent. The wisps of reiatsu seem to serve the purpose of vibrating the reishi particles around him, being able to deflect opposing spiritual particles. Because the reishi vibrates at roughly nine million times per second, not even the Quincy's Seele Schneider can cut through Seireitou's dense reiatsu. Once reconstructed, Seireitou's spiritual power increases further. Now that his reishi is vibrating at further speeds, his power has become something completely new, having a unique feeling to it completely unfelt by any other.
 * Enhanced Shikai Abilities: Seireitou's Shikai abilities have been explosively supplemented, allowing him to utilize Third-Order techniques at the very instant of Bankai activation. One such power, "Ōnoyoroi, Hanullim", is put into effect upon the very instant that Seireitou's Bankai is activated but is normally unseen by the eyes of anyone else unless Serieitou himself wills it to be seen. In addition, the power of Hanullim's corrosive base technique is greatly enhanced, concentrating the sheer destructive power along the edge of the blade of the Bankai. In doing so, anything cut by the blade is disintegrated into absolute nothingness, bypassing the rate that the base Shikai technique was normally restricted by. The defensive power of neither the Blut Vene nor Hierro are not even capable of standing up against this power. In regards to the other Shikai abilities, Seireitou can utilize them in similar manners as he could before, addressing them with their respective commands and "Shinwaryeok Hanullim" instead.
 * Devastating Speed: His speed is enhanced astronomically, able to move great distances in an instant as if to displace himself. Seireitou's Bankai enhances his speed to the point that even captain-level opponents cannot register his movements. He was shown to match the Bankai-empowered Hibiki in terms of speed, being able to match and counter each and every one of the latter's attacks, being able to push Echo to his absolute limits of speed. He moves at such exceedingly incredible speeds, that Ryan once noted it almost seems like "the entire space around them slows down when Seireitou moves." Seireitou was able to overcome Raian's Shunkō-enhanced speed, and place his hand on Raian's shoulder nonchalantly, the very next moment. After overcoming his despair, his speed was further enhanced, as he seems to flicker from place to place using a flash of light when engaging in acts of speed; capable of dematerializing himself from one place and re-materializing himself at a distance by literally breaking down into white particle shards and reassembles himself, making a strange phaser-like sound when in movement.
 * Strength & Durability Augmentation: Seireitou has become strong enough to cause a shockwave after being knocked down by Echo. His skin and hands are also strong enough to catch and hold onto Hibiki Asakura's Zanpakutō while the latter is in his Bankai form without any damage. His strength has also vastly increased in strength to the point where Raian (prior to his fusion with Yamamoto) and Mashū's combined Bankai attacks have no effect at all. Because of this, he can withstand a level 90 destruction spell without suffering any severe damage. With little effort, Seireitou is able to cut off the right arm of Yokibō from his body; the latter commented that he cut through it "like a hot knife through butter." With Shinwaryeok Hanullim's reconstructed state, its blade's own force almost becomes inconceivable. It was shown strong enough to block several high-level Kidō effortlessly, and also cutting through the body of an Arrancar's hierro without needing Seireitou's own spiritual force behind it. After overcoming his despair, his strength has increased to the point where a single swing of his sword can level a mountain.
 * Enhanced Shiroenryū: Despite being a self-created Kidō style, it is integrated into the Bankai's design. Because of this, the full power generated by the immense flames of Shiroenryū are incorperated into the blade itself. It does not burn what it comes into contact with but rather it simply incinerates anything it touches, leaving no trace behind as those struck by it are rendered to smoldering ashes. Because of this, it can seemingly contend with the equally-destructive powers of Raian's own Bankai. When he chooses to dematerialize Shinwaryeok Hanullim's blade form, he can actually compress the immense powers of Shiroenryū to both of his hands, allowing him to fight hand-to-hand while retaining the same destructive power while also making use of the powerful flames in widespread scopes. It goes without saying that fighting this way causes the effectiveness of his Hakuda to become further enhanced.


 * "Shōjiru, Shinwaryeok Hanullim" (出す真如天実, "Reconstruct, Shinwaryeok Hanullim"): Whenever Shinwaryeok Hanullim meets another strong entity in combat, a fragment of that opponent's energy is taken by the Zanpakutō, which allows it to become stronger. The power that evolves inside of Hanullim (and subseqently, Shinwaryeok Hanullim) is displayed in the Bankai, in various unique techniques. Another unique characteristic of Shinwaryeok Hanullim is once it evolves to a certain standing, it will actually "reconstruct" its soul and ultimately the Bankai release. When this occurs, a large amount of spiritual energy flows out the mirror, surrounding Seireitou in a cocoon, which goes through the process of reconstruction. However, the entire process is time-consuming, and Shinwaryeok Hanullim warns Seireitou to only use it when fighting alongside comrades. The new capabilities that Seireitou is then capable of preforming are sealed into the Bankai, allowing for him to use it via this aforementioned technique. While Seireitou's appearance does not change whenever this technique is utilized, albeit the lavender veil around him has become golden, the Zanpakutō transforms into an entirely new appearance. Its blade has grown bigger, taking on the appearance reminiscent of a kitsune fang. What's more noticeable is that it is made of pure diamond, instead of steel as most Zanpakutō are comprised of. The guard is no longer visible, instead being made of a large tuff of fox fur, fitting the shape of the blade as stated. Its hilt is shown to be the very same used in Hanullim's sealed state, retaining a white color as opposed to a golden color in the Shikai. Dangun theorized that the fear of failing Shiori sparked the process of evolution, and the fear of death finalized the end result. In addition to the change in Shinwaryeok Hanullim's appearance, Seireitou's own spiritual power has increased by massive amounts, retaining its white color with the addition of black wisps of reiryoku. However, its true power is revealed when Seireitou harmonizes his soul with Shinwaryeok Hanullim completely; essentially, in other words, controlling the interaction between his mind and his instinct. When this technique is activated, the fur around Shinwaryeok Hanullim that makes up its guard lengthens greatly, wrapping around Seireitou's right arm, which hangs outwards after reaching his shoulder, hanging back like a tail. Most noticeably, Seireitou's spiritual pressure is seemingly weakened severely. In fact, it was a result of joining his reiatsu and reiryoku together, instead of throwing one away to strengthen the other attribute, to the point where that it literally forms an invincible armor around him, appearing as a thin white aura of spiritual energy. Raian expressed the feeling to be strange, as it would be one thing to complete throw away one's spiritual pressure, but to literally weaken it to such degrees is incomprehensible. His spiritual force, strength, speed, and durability have increased further, being able to easily fight on par with Datara's transcendent transformation. When using Shikon Hisakiten, it appears as a massive amplified slash of white spiritual energy that covers the surrounding area and brightens the sky to the point of blinding weaker opponents, damaging anything caught within the light.

 * Ōhirumenoshī (大日孁貴神, "Great Spirit Who Shines in the Heavens") is a technique acquired from the Bankai form of Seireitou's Zanpakutō, Shinwaryeok Hanullim. While being in his half-dead comatose state, Seireitou was plunged into his inner world and forced to confront a demonic form of Shiori. This was because Shinwaryeok Hanullim explained that Shiori's death was the source of Seireitou's "despair", and because he allowed himself to fall into sorrow, his power began to decrease slowly until he would become a hollow shell of his former self. By finally accepting the despair and turning it into power, he was forced to confront a composite form of Shinwaryeok Hanullim and Sanagi. However, instead of battling the being, he had to accept Shinwaryeok Hanullim's blade, and be ran through by it. The blade, in turn, didn't harm him since it was his blade. Seireitou completed the interaction between his emotions and state of mind, with his spiritual power. This technique is the manifestation of this interaction, in which he becomes Hwanin (한인 (神の主); Korean for "Heaven Emperor", Japanese for "Divine Lord"). The usage of this technique is extremely dangerous, as it can cause strange interactions that are not within Seireitou's control. In this form, Seireitou's appearance changes drastically. The tear-like marks under his eyes that appear with Bankai increase in size and turn into a darkened silver. His silver hair becomes longer but much more tame, attaining golden armor which is styled to appear like japanese royalty. The chest plate contains sapphire embedded, which also extends outwards toward the shoulders, where the armor ends in two more sapphires on each respective side which hold up a long white cape. On his back, two large solid-gold wings with designs similar to the sheath of Hanullim. The inner edges of the wings are connected by a golden arc bar. Seireitou permeates with dense white reiatsu, mostly around his right arm.
 * Miryōkanna (魅了カンナ, Godless Heaven): Seireitou generates a white blade out of seemingly nothingness. Its appearance heralds a massive storm of white flames to gather above him, in which a large dense Sun descends slowly from the clouds. Seireitou is then able to direct the attack downwards, damaging anything caught within the wake of the massive sun. The flames then recedes, dissipating into the sky. However, Seireitou has also shown that he can focus the white sun on his person, absorbing the force of the flames to the point where his power multiplies by several factors for a limited amount of time.


 * Sokoshin'nyū (浸透侵入, Penetrating Divine Light): Seireitou calls forth an orb of spiritual power which he holds out in front of his two hands, which send a pulse of energy throughout the surrounding area. However, it is capable of being directed toward one opponent. It literally tears apart an opponent, by tracking down the smallest fragment of darkness within them; these can also apply to feelings of doubt or fear, or even arrogance. Those on the battlefield who witness the technique, such as Raian, note that they feel safe and protected, as if there's nothing to fear.

Bankai Stage 2
After training in Reiōkyū, whilst engaged in various sparring matches with Gamma Akutabi, Seireitou was able to achieve the Bankai Stage 2 (卍解二准, Bankai Nijun). Because Stage 2 is a state achieved through intense emotional content, it is presumed that he chose to train within the Reitoro in order to produce such an effect during his training; however, the actual method at which he reached this state is unknown as he is not shown actually awakening it during training. Gamma did note, however, that the surge of power that accompanied the initial unleashing of Seireitou's Stage 2 was sufficient enough in shaking the entire Shōkyūden palace, even while the training had occurred within Reitoro. Instead, its first use was displayed in the fight against Sōsuke Aizen, Yhwach, and Tadoku Getsueikirite during the War of the Worlds. In this form, Seireitou does not undergo a vast change in appearance as his clothing becomes far more refined and distinct, his attire taking on a more royal form as it now remsembles an unusual form of shenyi which would be more suited to a warrior that fights using unarmed combat. It is complete with a rope-like belt that keeps the uniform tied together. Just as in his normal Bankai form, the energy kitsune tail that is generated is maintained, although it can be lengthened and its density can be increased to serve defensive and offensive purposes. The integration of Sōkyoku becomes far more evident in Stage 2, as two huge wings composed of intense white flames erupt from his back, prompting others to call them the "Wings of White" (白の双翼, Shiro no Sōyoku). Both wings appear to generate amazing degrees of heat, but the true danger of their existence is that they emit a very unusual spiritual wavelength, akin to that of radiation that a luminous sphere of plasma held together by gravity would release, which bestows immense effects onto the surroundings that cause strange anomalies to occur in accordance with the techniques used in this form. Seireitou is acclaimed to have first theorized the existence of such a form before Raian had actually attained it. It has been noted among both allies and enemies that he and Micythos have very similar appearances while the former is in this state.


 * Power Augmentation: The Bankai Stage 2 grants an enormous level of power that causes Seireitou to transcend the precipice that he normally presided by in the core Bankai state, to the point that it is considered "worlds beyond" the Bankai. However, because of the tense relationship between himself and his Zanpakutō, it has been noted that Seireitou's Bankai Stage 2 is not as efficient in its duration nor its energy expenditure when compared to that of Raian and his Zanpakutō, Kanāji Fūshin, whom share a partnership based on compassion and camaraderie.
 * Transcendent Spiritual Power: Seireitou's reiatsu has become dramatically stronger and more intense than it was before, so much so that Seireitou could momentarily contend with an unarmed Kurama Kawahiru on equal terms. Along with that of Raian, Seireitou's power at this stage has been considered to have moved beyond the "level of spirits" and has ascended to the "realm of gods", although this is merely speculation on the part of various opponents of notable strength. The intensity of his reiatsu has become like that of Genryūsai Shigekuni Yamamoto in the latter's Bankai, as the reiatsu is so formidable that its pressure actually takes on the shape of raging white flames, to the point that it can burn away the existence of any normal combatants simply by being in close vicinity to Seireitou whilst he is in his Stage 2. By a mere glance, Seireitou's aura can take the form of multiple solar flares that erupt outwards and utterly decimate the surrounding areas and subsequently all opponents that become struck by its might.

Manifestation of Chaos
Several years after his defection from Soul Society, Seireitou was infected by a powerful Hollowfication virus prototype by Tadoku Getsueikirite and. The result was a Hollow named Grey. However, through personal training, Seireitou managed to control this power. Originally, to call upon this power, he formed a dense construct of reiatsu above his forehead and pulled it down, forming a mask crafted of crystal which was assumed to be the inner Hollow's spiritual energy in a crystallized state. The mask itself takes on a fox-like appearance, with its long ears drooping downwards. In addition, there were four thick black stripes that appeared to emerge outwards from the widened eye-holes of his mask and either disappeared into both sides of the lower jaw or traveled past the very top of the mask itself. It was following those events that in order to protect Shiori Miyamoto from Myōken that ended with the nature of the Hollow known as Grey which lurked within his soul to emerge and actually become influenced by Myōken's immense Shinkūmyō power, causing yet another transformation within the silver-haired man to occur. It had been believed that in addition to Hollowfication, Seireitou had now attained the energies of the evolutionary stage of Blanks, which suggested merging between the two as the use of both individual powers was continuously increased due to the enhanced threat levels that were necessary to deal with.

These two conflicting influences began to rouse the chaos that had been magnified by Seireitou's Zanpakutō, which led to the birth of a new entity within him that would serve as an extension of his very soul; known by the name of Sanagi, whom would serve as the manifestation of the very force of chaos that resides in an extraordinary concentration within all Sōzōshin. Because Sanagi is a part of Seireitou's own soul by serving as a unique form of his inner chaos (as many others who managed to manifest the chaos force had never actually caused an entirely new entity to arise) and in doing so, both he and Hanullim serve as the source of Seireitou's power. Originally, Seireitou could not maintain Sanagi's power, but after beginning the process of awakening his inner Sōzōshin blood, he was able to enact full dominance over Sanagi. This is shown by his eyes changing into a more complex form, signifying his power being balanced with Sanagi's own power. They would take on a ripple-like pattern which would spread over the eyeballs, with light purple irides and sclerae.


 * Power Augmentation: While tapping into Sanagi, Seireitou's spiritual and physical capabilities are vastly increased beyond their former selves. In his final fight against Datara Kawahiru, the nature behind this power had seemingly undergone some strange shift which subsequently prompted his capabilities in the form to also follow suit. Accessing these powers would be identified by the change of Seireitou's eyes as well as the nature alignment of his spiritual power. While in this state of being, he has demonstrated even more frightening tactics which he doesn't normally use in battle.


 * Vast Spiritual Power: Seireitou's power in this form is greatly enhanced; his aura shifts over to Sanagi and changes color from white to a smooth lavender. According to Shiori, the continued release of it would cause tremendous harm to the Soul Society. If he should continue to clash with Kamui while in this state, and Kamui in his Bakkōtō-enhanced state, it would spell the end of the Soul Society. It's sheer strength was great enough to horrify Raian, Mashū, and Makōtō who sensed his spiritual pressure far away from the bottom of Sōkyoku Hill. An interesting feat about his spiritual energy at this stage is the fact of it being pure distortional energy, erasing anything that contacts with it; ideally making it an atmosphere of black holes. He was able to use his reiatsu as a shield and expand it out as an explosion for a destruction that affected the surrounding area. It wasn't until he accepted the composite form of his inner rosary and Shinwaryeok Hanullim that he had truly unlocked the hidden power he held. When combined with his Bankai's immense capabilities, even the second transformation of Datara Kawahiru was unable to comprehend this power, as he states that Seireitou is "standing in a dimension far higher than himself."
 * Immense Speed: While in this form, Seireitou becomes dangerously fast and evasive, able to dodge all of Raian's bala attacks with little effort and keep up with Kamui while he is using Shikai and wearing his Hollow mask. He seems to move like a bullet, rather than use a form of flash step. His already high levels of speed have increased to such amounts that in conjuntion with his own pure distortional spiritual energy, he can manipulate interactions. While using his Shinkūmyō powers, Seireitou's speed technique often shifts from Shunpō to Unarikyō (金切り声を叫び, Screech Cry), which is the Shinkūmyo equivalent and produces a "scratch-like" sound.
 * Enhanced Strength: This synergized form was able to push back Kaito Kawahiru with little effort, and put all of the Captains on the defensive with just physical power. He is able to easily strike through a target's flesh with a single nonchalant sweep of his bare hands. He can slash through structures with ease, even those comprised of sekki-seki. He effortlessly outmatched Datara's maximum-powered Cero with a single hand.
 * Telekinesis: Quickly after transforming, Seireitou is able to call Hanullim back to his hands with just the wave of his hand. He is also shown to be able to use a form of telekinesis on his opponent. He even showed usage of minor gravitational control; being able to repel and attract substances, reiatsu or even living beings. Through the synergization of his Shinkūmyō and Hollow powers, Seireitou gained a minor form of mind reading.
 * Enhanced Shikon Hisakiten: When Seireitou summoned his Shikon Hisakiten technique, not only did it's speed increase, along with it's overall devastating after-effects and immense power, but also drastically changed shape and appearance. It took on the appearance of a compressed orb of circling lavender reiatsu, with several golden reiatsu whips encircling around the compressed orb, having an almost spherical tornado-like appearance. When utilized at full-power, it gives off the appearance of a kitsune upon being fired from the blade.


 * Cero Lamparos (ゼロライト (白中空フラッシュ), sero ramuparosu; Spanish for "Light Zero", Japanese for "White Hollow Flash") or more grammatically correct Cero Lampara, is a full-powered white Cero with a dark red outline to it, which Seireitou states to be the extreme opposite to Ulquiorra's black Cero Oscuras. When using this technique, Seireitou concentrates his vast spiritual energy with only his index finger into an condensed stark-white Cero with great might. When fired, it shines an immense white light that can burn the surrounding area it comes into contact with, and even leave those who stare at it temporarily blind. Seireitou refered to it as "my Cero." The Cero Lamparos's range is vast, and is immensely powerful enough to completely shatter Ryan's Zanpakutō, critically injuring him in the process, and strong enough to destroy the entire Senzaikyū tower in Seireitei. Despite the Cero being a Hollow-exclusive technique, the very fact that his Shinkūmyō powers have offered this technique may indicate that his Hollow powers and Shinkūmyō may be reaching their final evolution; seemingly overlapping eachother.

Transformation
Chrysalis Form: The sorrow felt by losing Shiori had finally reached a breaking point, as Seireitou's powers began to shift into a new state altogether. Seireitou's Bankai had began to enter a new unified state, alongside that of Sanagi. His body's natural black and white wisps of reiatsu began to surround him in what appeared to be a swirling tornado of screaming souls. A dense lavender reiatsu overcame Seireitou's body, as it crystalized and hardened around his body. In this new form, he slightly resembles his Sōzōshin form in a way, albeit his face is replaced with a lavender canvas made entirely of sapphire, as his entire body is now encased in. He also has retractable crystal claws on his fingertips and toes, small furry black tufts, and long fox ears that appear to be solid crystal and stand upwards, similar to that of horns. Behind him, it is shown that he possesses a long crystal tail, almost exact in appearance to a fox's, but much longer in comparison. His eyes are no longer visible, but replaced by a pair of glowing crimson lenses that serve as eyes. Seireitou is also shown capable of opening his mouth, despite his entire face encased by the sapphire. Sanagi, in the aftermath of the first incident, called this the "chrysalis form", implying that there is more to this form.
 * Undefinable Spiritual Power: Seireitou's spiritual power becomes so great, it cannot be sensed by Seijin master-level opponents. It is also great enough to instill the thought that they aren't attacking anything. Despite this, the effect of Seireitou's newfound reiatsu on the surrounding is still evident. Initially, it appears as enlonged wisps of lavender and black reiatsu, completely overwhelming everything and anything within the range of Seireitou's spiritual pressure.
 * Enhanced Cero Lamparos: His stark-white Cero has become exceedingly more powerful, capable of completely overwhelming Kamui's Esalare release and causing large scale destruction to large portions of the surroundings. It is fired from between the tips of his fox ear-like horns instead of his fingers as he normally utilized it. This Cero is white with a dark red outline as before and now quad-focused.
 * Enhanced Shikon Hisakiten: Seireitou's Shikon Hisakiten appears as completely surrounding the Shinwaryeok Hanullim. The extent of its power is currently unknown as it has never been utilized in this form. Renge refers to this attack as a "Birōdō Getsuga" (ラベンダームーンファング, Lavender Moon Fang), referring to the attacks' lavender color. Seireitou has stated that the Lavender Getsuga was originally Sanagi's technique.


 * Heightened Strength: This strange and unusual power was able to push back Renge Yamato with little effort, and put all of the Seijin Council on the defensive with just physical power. A mere punch was strong enough to shatter the ribcage of a kidō-protected Renge. It appears that Tōkaru's Shikai wall also fell by an effortless attack on Seireitou's part. Seireitou's strength was great enough to effortlessly shatter Renge's strongest technique in Bankai: Niban Dankai.
 * Immense Durability: His new crystalized appearance is not for merely show, as it is capable of fighting against the Bankai of captain-level opponents without being scathed in the slightest. Even the might of Renge Yamato's second stage Bankai was unable to scratch this crystalized form. He willingly lets Tōkaru's Getsuga Tenshō collide with him, and remains unharmed.
 * Unrealistic Speed: This new form grants Seireitou speed well beyond that of others, namely even Echo Ichimaru, one who is defined by his law-defying speed. Kamui speculates that this form allows him to actually contract the space-time continuum between himself and his desired location. With this type of ability, Kamui explains that Seireitou's speed can continue to increase to a point where even Kamui himself will be unable to comprehend, let alone match.

Awakened Form: Unable to control this unusual new power, and absorbed by the fear of hurting those around him, Seireitou entered a comatose state. This was to ensure complete mental and spiritual alliance, as Seireitou faced trials by Sanagi in order to control his power. Once he entered the chrysalis stage, his body would start shedding the crystal around his body, as his appearance would change drastically. He now wears a gray shihakushō, along with a black hakama, held together by a firm rope belt. A black mantle with burnt edges is draped over his shoulders, that stays connected together by what appears to be a tomoe necklace. His hair has changed colors, transforming from its natural silver to lavender with a purple tint. It also becomes much longer than before, especially his side bangs. Probably the most strange change to Seireitou revolves around his newly grown kitsune ears and long kitsune tail, both being lavender in color. His eyes obtain color from their mysterious mystic white to a resolute dark lavender, but retain a strange mystic white outline to them when Seireitou releases his spiritual power. They give off an apathetic feel to them, with Raian noting that he could feel the "solitude" behind them. Subsequently, he stated that no matter how hard they fought, Raian could not tell what Seireitou's heart was conveying, despite the close connection between the two. It seems that his personality also changes as drastically as his appearance, as shown by his much more stern contrast in both facial expression and in verbal expression. However, following his final confrontation with Raian Getsueikirite, his personality seems quite different in this stage, depicted as being even more cruel than usual. It was shown that he had a tendency to play with his enemies in battle. The difference in persona implies that they are separate entities, though it is clear that they are the same person. Raian speculates that this personality is drawn from both Seireitou's own persona and Sanagi. Seireitou, while in this stage, wields a strange manifestation of Shinwaryeok Hanullim, named Kumiho Hanullim (구미호하늘님, Supreme Nine-Tailed Fox Being). As Kumiho Hanullim, the Zanpakutō takes on the most strangest form, losing the appearance to even be called a blade. It now consists of a metal blade without any form of handle or guard, the blade's shape reminiscent of a japanese longsword. In order to be held without Seireitou's hand being cut, Hanullim now has a white cloth that is wrapped around one of the ends, that serves as a hilt. The simplistic appearance of Hanullim in this form causes opponents to gravely underestimate Seireitou, as shown in his fight with Sao Jiang. At will, whilst in this form, Seireitou can generate nine lavender-colored sapphire tails from behind him, resembling fox tails. These can be used for offense, and even for defense, as they can be made to move at Seireitou's whim.
 * Instantaneous Cero Lamparos: Being the only power shown in this stage, due to Seireitou using this form just once so far in a battle with Akujin, he can fire an instant and destructive Cero Lamparos from his fingertip. It's color has changed from it's stark-white with a dark red outline, to a darkened lavender with a solid mystical white outline, not unlike the appearance of the edges of Seireitou's eyes in Bankai. It was quick enough to completely devastate the entire Rukongai, from the Seijin Temple to the Seireitei, which is an estimated nine miles in length, and strong enough to completely penetrate the Seireitei's sekki-seki walls, despite being shot from several miles away. It's very presence can scorch the clouds in the skies.
 * Unrecognizable Spiritual Power: Reaching a point where it can no longer be called spiritual power, Seireitou's reiatsu has further increased from his chrysalis form. Unique to Seireitou's awakened transformation alone, it appears that he can change the properties of his very spiritual energy. It usually circles around his surroundings as puffs or clouds of spiritual power, that usually shift from a calm lavender color to a mystical white. Renge comments that these clouds are manifestations of Seireitou's feelings and emotions that are being influenced by his monsterous spiritual power. Being the most unique of all spiritual powers thus far, Seireitou's powers work in the exact opposite to Raian Getsueikirite's power. Instead of being unable to sense it, one who feels Seireitou's power will sense it all around them, being unable to pinpoint Seireitou's existence. Kamui claimed that he could "somewhat" pinpoint it, further commenting that only one of Sōzōshin heritage or equally-powerful status could fully comprehend its might. When using this technique, Seireitou glows with a thin red hue of spiritual energy, and his sword strikes unleash massive waves of white spiritual power with every swing. Kamui noted how heavy his spiritual power is in this state, and even noticed how it was almost as solid as crystal.
 * Physical Augmentation: It was noted by Kamui that Seireitou's physical abilities were unlike that of his Bankai. His arm strength, leg strength, resistance, and speed had become significantly increased, to the point of making Kamui's Bakkōtō power look like nothing. By his own claim, Kamui stated that using his Bankai against this form would end in the same result. Seireitou had to cushion the impact of his blade by making it blunt with his "crystallized" spiritual power, albeit it still crushed right through Sannotō's Zanpakutō, and left a massive gash on the former's chest. Seireitou's strength has also reached frightening heights, even by Seijin-level standards, allowing him to take on the force of all but the most strongest attacks without needing to dodge or block. In fact, his strength allows him to shrug off the force of a point-blank attack from Kurama Kawahiru. With a simple flick of his finger in Renge's direction, he was able to push back the latter through three buildings, albeit being a considerably short distance between them. By flicking his thumb from inside his fist, he could form a miniature vacuum which would function like a bullet, shooting the target that Seireitou designates. In addition, his level of movement transcends all forms of speed enhancement, foregoing the need for flash step. Whenever he moves, he appears from one point to another point, leaving behind a small hue of white spiritual energy.

Relationships
Being a man whom values his bonds, Seireitou has formed several unique and interesting friendships, alliances, rivalries, and even enemies due to his actions and viewpoints. Interestingly enough, several female characters in the series have possibly developed romantic feelings for him despite his strange and eccentric persona, though most likely a result of his inwardly compassionate nature.

Seireitou is not known to be close with his immediate family. He is estranged from his "father" and his mother for obvious reasons. While he is known to have had a lover, Seireitou was married only once. His wife, Shiori, had been killed during the events of Datara's campaign of warfare. He is also known to be on rocky terms with his son, although the latter seems to have much respect and admiration for his father while the former cares deeply for his son; despite the both of them being incapable of portraying this father-son care for one another. He has also conceived an illegitimate daughter that was the result of a drunken exchange between himself and Rangiku Matsumoto.

During both the Hollow Wars and the Quincy Blood War, Seireitou was known as "Shiroyasha" for many frightening reasons, including his bloodthirsty battle-loving attitude and desire to cause vicious injuries upon his victims; although one of the most fearsome reasons was due to his "unique" method of intelligence gathering which involved the capture of several females among the enemy ranks to be raped and subsequently tortured for information. According to Seireitou, he has assumed to be the sole person responsible for the rape at least forty-seven female Arrancar and sixty-three female Quincy, four of which in regards to the latter were among the Stern Ritter; most prominent among these included Luciana Basterbine. Several offspring were later determined to be conceived from these unions, such as Bambietta Basterbine and Meninas McAllon, among many others; although it is unknown if Seireitou is aware of each and every one of these bastard children.

Anime Omake Segment: Sei-san no Kyōshitsu
Seireitou is in charge of the Sei-san no Kyōshitsu (の教室, literally "Sei-san's Classroom"), an omake segment that airs at the end of some chapters in the series. It is where he outlines various facts about characters in the series, as well as instructs the audience in subjects not fully covered in the actual chapters themselves, teaching it to a classroom full of the main characters dressed in school uniforms. Similar to Gin Ichimaru's Arrancar Encyclopedia, many sketches will usually start with a surprise guest(s) for that segment announcing the name of the sketch, at which point Seireitou will give a short course on a specific topic, such as the character in question's standard abilities. Once Seireitou has finished, the person that announced the name shows up to comment on the topic, usually resulting in a humorous retort by Seireitou. During these segments, he also answers fan mail. On occasion, Seireitou will be "out sick", in which one of the other three Yonkō will substitute for him, typically Raian Getsueikirite, which almost always leads to a humorous subsequent scene involving Seireitou realizes who's substituting for him.

Quotes

 * (To Raian Getsueikirite) "It isn't a sense of justice. Fighting powerful opponents and protecting those close to me is how I live my life. It is the path of which I have chosen to walk. If you measured good and evil deeds by current laws, I would be responsible for many crimes. That is why I only take on fights which pique my interest. It isn't justice whatsoever. If it means saving the life of a friend or advancing my own power... I'll do whatever it takes to win. I don't and will not play fair. I'm a dishonest cheat who hates losing."
 * (Regarding Shiori Miyamoto) "I've decided to stop whining about what I've lost before... in order to focus on what I have now. I'm going to become her guardian and become the strongest so that things will change for the better. Perhaps it's selfish of me... but I no longer want to have to... see her cry any more. If it means changing this entire world, even if it requires the most violent means possible, so that she'll never have tears for me to wipe away any longer, then that's good enough for me."
 * (To Hikaru "Shadow" Kurosaki) "Quit being stupid. Stand up. If you've got enough time to fantasize about your beautiful death... then why not live your life beautifully to the end?"
 * (To Genryūsai Shigekuni Yamamoto, during the Quincy war) "If you believe that I serve as a Captain of your Divisions so that I can protect the civilization that you and the rest of these murderers have so painstakingly worked toward creating, you're dead wrong. From the start of this, I've sought only to protect Shōyō-sensei... and also, Raian-san, Shiori-chan, Senka-chan, Hikaru-san, and even Echo. Do not forget that it is akin to blackmail that you got me to go along with your little "Gotei" group. You had best not forget your place when speaking with me, old man. I have no qualms about killing every last man, woman, and child that dares to swear loyalty to you. I will smash to bits this entire Seireitei if I have to."
 * (To ) "A warrior has only one job on the battlefield. And that... is to win. There is no such thing as a "good side" or a "bad side" during a conflict. When at war, both sides are in the wrong. You must shed the childish thoughts of respect and honor... and become a demon. That is the only way to survive on this battlefield."
 * "You should know better than to corner an animal like a fox... we have a tendency to show our teeth."
 * (To Datara Kawahiru) "Get up, you miserable fuck! It's time you learned why you're not in our league!"
 * "Sometimes, it's a pain being the strongest among those who fight. Those who have the greatest power amongst their group, have the innate responsibility to ensure their own and their fellow compatriots' well-being. When they have the ability to take action, it is their duty to take action. However, while it may be a tribulation, should one of the group members fall, the burden of that loss is weighed on the strongest one's shoulders, as the one who failed to protect those under him. In this way, nobody can be blamed but yourself. But you see, it is precisely this reason why I strive to be the strongest among those around me. So then... I have nobody to blame but myself if one of my friends die on the battlefield."
 * (To Datara, the final battle) "Interesting... Tell me, Datara. Why did you just distance yourself from me? Weren't you the one telling me that distance only matters in a battle between equals? Is this your way of telling me that you're scared of what's happening right in front of your eyes? Of something happening... that you can't understand?"
 * (When training Ahatake Kurosaki) "You are a fool, nincompoop. For I am not here on any official business other than the hopes that I will find either breasts I can fondle or an ass I can kick!"
 * (To Sao Jiang) "I'll give you a chance here. If you leave now, then I won't kill you, and I won't need to use my exceedingly valuable time to investigate the motives behind your actions, once again screwing up an evil mastermind's plot to take over the world or something cliché like that. Savvy?"
 * (To Saori Sumeragi) "Saori, it takes a lot to get me worked up... but this time my boiling point's as low as it's ever been. The "Silver Hairs" Seireitou, the man regarded as the "white demon" Shiroyasha... is about to go on a rampage!"
 * (To Minato Kuramoto, and later Miharu Kurosaki) "Try to picture the toughest, most intense, most terrifying training you can possibly imagine. So, did you imagine it? Now imagine that... was Heaven."
 * (After refusing the Royal Guard's request) "Sorry, I'll have to pass on that. My doctor says that I have a malformed public-duty gland and a natural deficiency in moral fiber, and because of that, I am therefore excused from having to save the Soul Society."
 * (To Klaus Nietzsche) "Listen... What you do in the spiritual world or even here in the world of the living matters very little to me. Do whatever you want there. But anywhere within the reach of my sword... is my country! Anyone who comes in here and messes with my people... whether they happen to be enforcers of justice, bringers of darkness, or even the Spirit King himself... I will cut them all down!"
 * (To Tadoku Getsueikirite) "Even if we're just flickering candles... by gathering together, we can illuminate the darkness. Even if the flame is put out, if it's left for just a minute, it can start another fire. No matter how many times you try to put me out, you're just wasting your time. I have coals set aside. I won't disappear, those coals are with me always. As long as I have them, no matter how many times I'm put out, I'll keep flaring back up. Someone like you... can't put out our flame!"
 * "Since you're so willing to use such a killing move... then I shall use my own killing move as well."
 * (To Saori) "No matter where you are, no matter how scared you are, the sun is there. However, that sun... is often covered by clouds. But if you continue to watch the sky, it will eventually make its way through the clouds. That's why... we must never lose sight of that. We must never stop staring at the sky. Stand up straight, watch the heavens, and continue to live your life. Tell everybody you see who looks depressed... to watch the skies. In this filthy, dark, lead-colored sky... I'm going to drag down a ridiculously-bright huge-ass sun."
 * (Regarding his and Kamui's Zanpakutō) "If Shinbyeong is a Zanpakutō that changes and decides fate, then Hanullim is a Zanpakutō that challenges fate."
 * (To Odo Marquard) "You think that you can strike me down because you stole Shinwaryeok Hanullim? How naive. Why do you think that I was feared as the Shiroyasha for so many years? It is because, in all this time, the tenacity that I have toward fighting... has never once been rivaled!"
 * (To Hōsen Kuramoto, about Shōyō) "Well shit... Perhaps you're stronger than I thought. But that's no excuse. Even as things stand, I can feel the same chills up my spine from back in the day. It's as if he's scolding me... even in death. "To have trouble with such an opponent, I don't remember raising such a coward!" is what he'd say."
 * (To Tome Kūgun) "You fight only with instinct. Perhaps, in some ways, that is an admirable trait in a Hakuda fighter. But not a Master. Masters are those who abandon reason, instinct, logic... and even truth. For those are nothing but limits that restrict the Master. The way that you fight is akin to that of a mutt blindly following the word of its master. That's what you are, a puppy-dog. Without even considering the circumstances, you charge in headfirst, letting your instinct be the master calling the shots. But you see, demons think a bit differently. Not bound by instinct. We're fully aware of the damage we cause... and enjoy every moment of it. The mistake you made, puppy-dog... was stepping into the ring with a demon. You're out of your league here, hound."
 * (Speaking to several opponents) "As I've already told you, the only one who could repel my attacks successfully was Raian-san. Too bad he isn't here at the moment. Though... in a way, that's a good thing for all of you. Because if it's just me... the maps won't need to be so drastically redrawn this time."
 * (To Gekkō Kirameki) "Killing has never been something I've been capable of doing on a whim. In this sole regard, I am different from Raian-san. However, my pride as a martial artist prevents me from operating under such a principle when confronted by an opponent who is prepared to put their soul at risk. With such spirit opposing me, I will never regret... wearing the title of murderer."
 * "Blah, blah, blah, blah... quit your blabbering. Are you in heat or something, bastard? You kept yammering on for so long that I only really caught the first half."
 * "I'll never be able to protect anything? Hardly. My hands may be stained with blood, but there are still things that even they can protect."
 * (To the Mimagotei troops, about his Dojang's female residents) "Good grief. We've got three world breakers with us. I'll give you some advice. Call for reinforcements. You might be the noble houses' personal guards, but you're probably too soft from all the peace and quiet to take us on. Meanwhile, we're still at war, fighting for our lives everyday against those psychos!"
 * (Regarding the students of Kawahiru Dojang) "I don't mind you spreading whatever rumors you want about me. If I'm being an eyesore, then I'll be on my way somewhere else. However... if you point your swords at my students, then I wouldn't mind overthrowing something like a government."
 * "It has been long discussed, for countless centuries, what the way of the warrior is, and never is there one answer. However, one thing is persistently mentioned in every interpretation: that warriors must never stand still; they must fight. When I look at the blossoms from these trees fall, it makes me believe that we share the same fate. And that we are all approaching death, the only variable being when. If this is what the destiny of all men is to be, then a warrior is one that fights until that time comes. They are those that know life in every breath they take, every cup of sake they drink, every enemy they slay... That is the way of the warrior."
 * (To, regarding ) "Me and him are no more different now than how we were back then. In order to become the Shinigami that each of us holds in our heart, each of us has been fighting with ourselves. This guy's version of Shinigami... The way he does things, I can't accept it. So even if I have to strike him down, I'll stop him. But the one who understands how he feels, better than anyone else in this world, is me. What we hated most in this world is the same. So, you guys... aren't qualified to cut him down. The one that will both strike down and protect this guy... is me. No matter what happens, I will protect the soul of that man's disciple... Getsueikirite Raian of Shintai Sonjuku... as both his comrade and as the disciple of Master Shōyō... Kawahiru Seireitou. That's... the kind of Shinigami I decided on being."

Behind the Scenes
Seireitou's theme songs, as chosen by his author, are "Utage" by T.M. Revolution and "Status Quo Destruction" by SPYAIR.

According to the author, Seireitou would be voiced in Japanese by Sugita Tomokazu, the seiyū for Gintoki Sakata from Gin Tama. He would be voiced in English dub by Dustin Hoffman, the voice actor for Master Shifu from the animated movie Kung Fu Panda.

While Seireitou is his first name and Kawahiru is his last name, his full name is Seireitou Shōin Kawahiru no Jirō. Kawahiru no Jirō means "second eldest son of the Kawahiru family" whilst Shōin means "pine trees in the dark", which was the name given to him in birth by his mentor and grandfather, Shōyō. and serves as a foil to the latter's own name which translates into "pine trees in the sunlight". The name Shōin was derived from Yoshida Shōin, whom is one of the author's most respected role model. Seireitou's first name means "guardian of the spirit".

His title, "The Tiger of Kabuki", was based off the title "The Tiger of Kai" that was held by Takeda Shingen, an important feudal lord during the Sengoku period of Japanese history. This was meant to show the parallels between Seireitou's rivalry with Raian and Takeda's own rivalry with Uesugi Kenshin, whom held the title "The Dragon of Echigo". By many historical accounts, Shingen and Kenshin had always been interested in Chinese culture, especially the works of Sun Tzu, with the Dragon and Tiger having always been bitter rivals who constantly try to defeat one another.

Prototypes of this character's article are Seireitou Kuchiki and Seireitou Kawahiru (Bleach Nagareboshi).
