"A man's life is like traveling down a long road with a heavy load on his shoulders. The first time I heard that, I thought, "what a lame thing to say", but what do you know... there was a point to it. It's not really a burden. Everyone's got both hands full of something that matters. You just don't realize it when you're carrying it. It's only after it slips out of your hands that you realize how heavy it was in the first place. So many times, I thought I'd never carry a load like that ever again. And yet, before I realized it... I was carrying it again. I'd feel so much better if I just got rid of it. But I just can't bring myself to do it. Without those guys, just walking around isn't fun anymore."

- "Warring with heaven, there stands the white-haired demon, fighting for his soul." - Seireitou-shishō
Seireitou Shōin Kawahiru no Jirō (河昼 次郎 松陰 精霊冬, Kawahiru no Jirō Shōin Seireitō) is a male Soul born of Sōzōshin and Kitsune blood. Though he started as a mere Shinigami, he went on to become a Transcendent being. He is the leading titular character of Bleach Silver. Born as a child of the Soul King via the Divine Advent, Seireitou was conceived by Tsuyuri Kawahiru and is the twin brother of Kamui Kawahiru. By way of this relation, he can also be considered a distant sibling to Yhwach. However, despite this, he did not inherit the power of the Soul King, and was written off as a child "never meant to be born". Seireitou was the first Captain of the Eighth Division within the Gotei 13, preceding Shunsui Kyōraku, as well as being the Division's founder; serving as the one that laid the framework for its existing foundation. Those who first joined him would become known as the Silver-Hairs Gang. He was known and feared throughout countless regions as the Shiroyasha (白夜叉 (シローやくしゃ), Shiroyasha; Japanese for "White Yaksha"); earned primarily during the events of the Quincy Blood War because of his demonic-like appearance on the battlefield as well as his white hair and white Captain's haori. During his tenure as a Captain, Seireitou was engaged to Senka Kururugi, and following her execution, he had rebelled against the Soul Society which culminated in his open defiance and subsequent defection from his post. Alone, Seireitou inadvertently found himself on a pilgrimage to the Beast Realm. While there, he engaged in countless exploits and encountered all manner of spirits; eventually, his path led him to an ancient spirit named Kachōfūgetsu, who provided him tutelage in refining his powers and later christened him with the name Fūrinkazan (風林火山, Fūrinkazan). It was during that time that he would fall in love with Shiori Miyamoto, who would become his wife and whom later returned with him to the Soul Society. Prior to his beloved wife's death, they had conceived two children; an elder son named Suzaku Kawahiru and a younger daughter named Kaguya Kawahiru, the latter of whom was believed to have died in a tragic incident. Upon his return to Soul Society, Seireitou would earn a name for himself as an undisputed master of Hakuda; defeating the greatest of all martial artists in legendary bouts, such as his fight with Yukara Shihōin for the title of Yonkō, and the battle with Shizuka Yuko that was elevated to the status of myth itself. In the end, he had conquered the world of martial arts and was left unopposed, becoming illustriously revered as the Soul Society's Hakuda Grandmaster (白打宗家, Hakuda Sōke; Japanese for "Head of all Hakuda Schools").
When Seireitou first returned to the Soul Society, he had become a sort of wandering sage, educating those who lacked the necessary spiritual power to serve as Shinigami in the art of Hakuda. Throughout his travels, he was faced with a variety of dangerous opponents and their radical agendas, briefly including that of his own twin brother. Yet, he managed to overcome those tremendous obstacles time and time again, seemingly without consequence. However, Seireitou suffered due to the death of his wife by the hands of Datara Kawahiru, which left him in a forlorn state of mind for a long period of time. Decades later, following his encounter with Saori Sumeragi, he managed to deal with his personal darkness and subsequently went on to create the Senjukha, serving as its head master. Stationed in the Kabuki District of Rukongai, he would live there together with Saori, as well as Botan Nakandakari, Kuniharu Inuzuri, and Rinnōbō Yoshioka, who came after as residents and masters of his school. Seireitou would only come to take on a handful of students in the centuries that followed, with his current resident disciples being Minato Kuramoto and Hinata Kusuhana. In addition, due to a significant decline in proper combat arts being taught to potential Shinigami students, Seireitou is often requested by Soul Society to serve as a Hakuda Instructor within the Shinō Academy on occasion and conduct martial art seminars. Though he does agree to these requests at times, Seireitou is rather reluctant to carry out these classes for whatever reason, even going as far as to orchestrate advanced classes so difficult that many students refuse to participate out of fear, just so he can avoid long teaching hours while still receiving compensation for his time. However, there are times when certain individuals, such as Yūshirō Shihōin and Kazui Kurosaki, endure the challenge of attending these seminars and sometimes pique Seireitou's interest enough to be trained by him personally.
Stories of his legendary battles circulate throughout the world, speaking of the "White Summit" (白頂き, Haku Itadaki) who has defeated every Hakuda master, one after another, until there were none left to challenge him. Seireitou went on to be regarded as an absolute authority of the martial arts, respected even by the Eight Sage Fists. His prestige as an unrivaled master of Hakuda equates his status to a position of eminence in which many aspiring warriors wish to seize from him in their quest for recognition. By continuously reigning at the summit that looms over all martial artists, Seireitou has caused many to seek his head while also prompting many to bow their heads in respect; especially among those who hold power in the Soul Society, such as the Noble Houses or the Four Heavenly Kings. Both his capabilities and his experience are valued highly by the Soul Society, to such an extent that he is often requested by either Central 46 or Captain-Commander Shunsui Kyōraku for particular cases that require a specialized hand. These often involve anomalies within the spiritual realm that are of a volatile and mysterious nature that even the Shinigami themselves are ill-equipped to deal with the problem themselves. It is not uncommon for even the Royal Guard to approach him in certain matters. In this sense, Seireitou can be best regarded as a consulting affiliate of the Soul Society as a whole; of course, he is infamous for being difficult to work with and only helps when his personal interest has been piqued.
Characterized as a man with a boorish expression and 'eyes like a dead fish', Seireitou is particularly youthful in his appearance despite his advanced age of nearly two millennia. He has flowing white hair with a particular silver tint that has gone through different lengths throughout his lifetime though it is often kept on the long side, nearly reaching down to the small of his back. The bangs tend to frame the sides of his face, but more often than not, his bangs hang over his forehead naturally. Similarly, his eyes are of a grey coloration, though tend to reflect a crimson afterglow. Though he was clean-shaven for most of his earlier adult years, Seireitou had later grown out his facial hair in varying degrees, often settling on a thin mane that envelops the bottom portion of his face. As a Shinigami, he typically wore the standard shihakushō uniform, though with subtle differences, as instead of a classic tight-fit obi, his was more of a sash; a light purple color, as opposed to the white often worn by others. Once he became the first Captain of the Eighth Division, he had a white haori with long bell sleeves that was draped over his uniform. He continued to wear this well after defecting from Soul Society, though he eventually abandoned the haori. As he advanced into his Beast Realm pilgrimage, he went on to discard the shihakushō as well. Seireitou came to dress in a more traditional martial art attire, something between a shenyi and a judogi. After returning to Soul Society, he wore a more western robe, something akin to a scholarly or traveling sage; a look he kept to for the most part while wandering along Rukongai. While he still possessed a Zanpakutō, it was often worn on his right hip, kept fastened to his waist by the obi he was sporting.
Over the centuries, Seireitou eventually adopted his signature look; a shihakushō that was of pale white, almost of a pearl shade, with black trimming along the edges and running down the outer sides of his hakama. This robe is often open partly at the torso, revealing some of his upper chest. He also would wear a haori of a brighter, more snow white coloration, with similar black bars running down the sleeves and edges of the robe. Seireitou continued to fasten this uniform with a sash-like obi, though it was more of a lavender color than the purple one he wore as a Shinigami. Although his attire has often been compared to Arrancar, he does not wear the same black tabi and white waraji as they do; in fact, his remain the same as the Shinigami. Seireitou later adopted a newer version of this haori, one which resembled his previous robe but with the addition of silvery-grey shoulder weights. When in Senjukuha, it is rare for him to be dressed in this specific attire; often wearing more casual articles of clothing, such as training robes or a simple set of yukata.
- "Not even I could have seen this coming. He is someone that I cannot comprehend. Kawahiru Seireitou... That man defies all reason. Without a doubt, it was his bad influence that was responsible for my sister's stubborn streak."
- —Micythos Azazel commenting upon Seireitou.
Without a doubt, Seireitou is considered an oddity even among other unusual individuals. If there were to be anything about him that could be considered characteristic, it would be that he is uncharacteristic. To some, he is perceived as a wise master, a battle-hardened warrior trained in both warfare and strategy, while to others, he comes across as childish and perverse, even flamboyant at times. He is typically described as laid-back, unmotivated, and even useless. Although, those same people also seem to note his kind, responsible, and unpredictable self. He is a man that can impart sage-like wisdom onto others, while simultaneously being someone that lounges around wearing a dumb expression and goes on nonsensical rants about the most trivial things. Serious but easy-going. Stern but eccentric. His inconsistencies gives off an initial impression of being heroic and honorable, while later on revealing his motives to be self-serving. There can be no denying that these are all aspects of his personality. Yet, it is foolish in and of itself to be misled by his mannerisms. It has been mentioned that if Yhwach were to believe he would purposely involve himself in the Quincy Blood War, Seireitou would undoubtedly be classified among the special war potentials for his unpredictability. He prides himself in 'keeping things simple', often leading others to believe he is a simple-minded person, but his intellect and insight are as sharp as blades. It becomes difficult to gauge whether what he does is all in the process of manipulating those around him masterfully or if he really is just that carefree, but what is indeed an error in judgement is to define Seireitou as being one or the other; to do so would mean having already lost the ability to understand him. What can be said for sure is that his wisdom and cunning are beyond measure; even moments of irrationality may actually conceal a deeper purpose. Simply put, there is no way to tell when he is intentionally trying to mislead someone by his antics or if that is truly an aspect of his real personality. Tetsuro Ryuzaki commented that Seireitou is unpredictable, and it is almost impossible to discern his thoughts or his motives. Despite his arbitrary facets of behavior, he is undoubtedly a cunning and sagacious person; almost machiavellian in nature.
If you could define him in any particular way, it would be that Seireitou embodies openness and direct emotional expression. He has been described as somebody who, if offered a comforting lie, would 'hit you over the head with it'. That is to say, it is not that he is indiscriminately honest; lies and deceit are his bread and butter, that is to be sure, but he does not believe in providing false hope for the sake of cheering someone up. Seireitou is a man that firmly believes the best way to live is to just be yourself, highly valuing the individual over ideals or beliefs, although this humanistic mindset is also seasoned with hints of misanthropy and skepticism. His cynicism and borderline self-importance, for instance, are not behaviors he tries to mask; rather, he is upfront about them, regardless of how uncomfortable that may make others. His whimsical and lighthearted attitude is equally an aspect he is prone toward expressing even if the moment seems inopportune, to tremendous effect so much so that it can come off as overly exaggerated. These behaviors can often materialize as a unique sense of dry humor and sarcasm, even leading to comments or actions that can throw off a person's own emotional state, which adds to the manipulative quality of Seireitou's personality. Even someone who is putting on a tough and serious front, such an attitude can be dissolved in mere moments when interacting Seireitou; no more than a brief interaction with his quick and sharp wit can knock even the most serious individuals off-guard. His regular use of inappropriate dialogue and scatological innuendos are often examples of this and tend to paint Seireitou as being incredibly perverted, which pairs with his tendency to call out profanities without quarter. However, this is also seen in his blunt and unreserved manner of speaking, which is displayed in instances where he feels no regret in telling people what he thinks and what he believes they need to hear, even if they themselves do not want to hear it. To that end, even if it hurts their feelings or exposes their vulnerabilities, Seireitou is not one to back down from addressing them straightforwardly. All the same, he is capable of maintaining decorum when he wishes, showing politeness and respect to those he believes either deserve it or are feints used in feeding an opponent a false sense of security. While there are definitely aspects of himself and thoughts he keeps to himself, he greatly boasts the importance of speaking and acting out how one feels deep down. Holding oneself back and letting such thoughts fester inside is the mark of a weak person. In particular cases of irritation, Seireitou has demonstrated 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 and slammed the latter's head into a concrete wall without even questioning the situation. He, and by extension Raian, are also known to physically bully one another when the situation arises; often in response to something the other did that they considered foolish, even if said instance occurs in the middle of a battle. This is also seen in their interactions with old friends, such as Hibiki Asakura and Hikaru Kurokami. Seireitou's candid perspective only ends up fueling his own unrivaled stubbornness, as he is not a man to back down once he has his mind set on something and is not concerned with openly announcing his intentions no matter how disagreeable those thoughts may sit with others.
- "Most people that I confront are rather simplistic to describe, but you're a different story. You have a far more interesting rhythm. It's a tad illusive, scrambled up due to its poor form, making it harder to pinpoint. Something like jazz, perhaps? No, nothing like that. If anything, it's like the humming of a drunkard."
- —Shinsaku Kawakami analyzing Seireitou's behavior.
His characteristic of openly expressing his thoughts even at the cost of alienating others, coupled with an unparalleled stubbornness that refuses to back down, simultaneously appears to generate a peculiar charisma that sets Seireitou apart from others. This tends to attract people toward him, if only because he sparks some fundamental curiosity inside of them that drives them to seek understanding of an individual that is seemingly incomprehensible. This charisma has drawn many people to him, allowing him to have formed many friends and allies along the way, even out of former enemies. It is as of his way of living truly to oneself liberates others as well from whatever shackles them, emotionally or otherwise. However, there is a hint of hypocrisy in this point of view, for while Seireitou may appear open about most thoughts and emotions, there are those that he hides deep inside that he refuses to allow anybody to see; even to the point of severity. In spite of his willingness to confront others in a genuine manner, which is the root of his unique charisma, the stubborn part of him that refuses to share his troubles with others often inspires concern in those who care for him. Tsukuyo Sone once mentioned how Seireitou, in times of trouble, had a tendency to notice how worried everybody was, make an irritated face, and without a word to anybody, would go off on his own to deal with the situation in their place. Rangiku Matsumoto has also described him as 'the sort of shitty guy that could never make a woman happy, yet someone who ends up in everybody's hearts despite refusing to belong to anybody regardless of the circumstances'. Although he may be a person that is direct with his thoughts and feelings, he is by no means a man that is prone to losing his emotional state of mind. Even in the face of danger or tragedy, even if the situation seems grim, Seireitou maintains his cavalier attitude, often engaging opponents attempting to kill him in small-talk or even joking around with them. In every set of circumstances, allowing something to influence and interfere with his mental state is a choice entirely his to make. Though he may feign the surrender of his faculties, Seireitou never allows an opponent to seize command over his own decisions and his own beliefs. To put it simply, he plays by no rules other than his own; valuing his own way of life and personal rules above any other.
- "That man, as aloof as he may seem, is dangerous. He is unnatural in his cunning, it's almost as if he's reading your heart rather than your mind."
- —Renge Kondō
Regardless of how he may come across, whether it be immature or facetious, there can be no denying the ruthlessness and brutality that Seireitou boasts. No matter what circumstances or situations he may find himself in, he is willing to do whatever it takes to see things through to the end, even if he must dirty his hands with the most horrendous of sins. He has no qualms about murdering even children or the innocent if that is what is demanded of him; inflicting torture and eviscerating those who get in his way. On some level, it would not be inaccurate to say that he is something of a sadist, which also comes across in his manner of speaking as well as his actions. When Seireitou had first learned about the original sin of Soul Society, he expressed his disagreements with how the Noble Houses went about their actions, yet understood their perspective even if simultaneously rebuking them for how they allowed fear and jealousy to warp their own judgement. It became less about the sin itself and more about the motives behind it, with Seireitou later commenting on how, regardless of the reason, they did what they thought they had to do in order to uphold their ideals. His words seemed to suggest that he would have definitely inflicted sins of equal, if not greater, reproach if his own circumstances were to prompt such a response. However, these are not acts he performs out of some bloodthirsty craving he seeks to satiate. The foundation of his actions are built upon his pragmatism, which when nurtured by his own uncompromising attitude, makes him someone to be feared as the lines to which he is willing to cross in order to get what he wants goes beyond any notion of morality or common sense. Once he has set his sights upon something, it no longer becomes a question of if it will be done or even how it will happen, but when; almost as if his own desires by that point have become a force of nature. This is further enhanced by his ability to remain composed even during moments of severe upheaval, maintaining a hold over his emotions that enables him to be ruthless yet calculating in any given situation. It makes him not only exceedingly efficient as a warrior but also marks him as a brilliant strategist and commander. In spite of how the circumstances may or may not shift, Seireitou holds his 'endgame' within his sights at all times; a result of his pragmatism that is bolstered by his unfettered sense of morality and his sheer level of preparedness.
At his core, Seireitou is a man that values potential above all else. This is often mistaken as being a love of life or a deep-seated desire to protect others; while these would not be wrong to believe, fitting the man and his ideals quite nicely, they also are far from the genuine truth. There is meaning in enjoying peace to him, but remaining stagnant in life is to be avoided. What he values about life is the potential it possesses; the possibility for growth and development, not just in combat but in an individual's own aspirations. He harbors under the belief of 'where there is life, there is potential'. Seireitou's willingness to defend life only extends as far as his own self-interest takes him. This is what he describes as his soul; composing the basis for everything he views himself as and the values he holds dear. Although he is capable of love and affection toward others, the tragedies he has faced throughout his life have warped his once-innocent perspective. His form of attachment is not what one might call orthodox, and often extends solely to those who he has a personal interest in seeing how they develop; whether that be as a fighter or as a person. It is born from a simple desire to see where their path in life takes them and what he can do to nudge them along certain routes he considers interesting. While for many others, this may be seen as a game of manipulation; a means to an end to get all the pieces of a chess board to line up in a manner befitting the manipulator. However, for Seireitou, these desires are entirely earnest. There is no hidden agenda, no ulterior motive; he just wants to witness for himself how far certain people are able to go, regardless of where those paths may lead. As such, the very concept of morality does not apply to Seireitou, for he may even be willing to commit acts of a malicious and villainous nature if he deems it appropriate. This is exemplified in a decision he made to train Grimmjow Jaegerjaquez in Hakuda, despite the fact that the Arrancar was undoubtedly going to use those skills for his own selfish desires, even if it meant several innocent people would die in the process. As Sōsuke Aizen was once described as, Seireitou is a man that treads along a path that knows no stagnation, and therefore, the notions of good and evil are equally insignificant to him. Everyone has their own journey in life which takes shape as a person's own 'way of being', their personal justice, beliefs, and their way of living, so to speak. If it is for the sake of something a person believes in, Seireitou believes that any sin is justified, even murder. For him, nurturing potential in others and bearing witness to where that potential takes them, is his own way of being; his own form of justice.
Of course, that is not to say that there are not those who hold special places in the man's heart. Chief among them would be his best friend, Raian Getsueikirite, along with the residents of Senjukuha, and later on, his students Minato Kuramoto and Hinata Kusuhana. While there are others that he demonstrates attachment and even sentimentality for, it is very rare for Seireitou to form connections that are not built solely upon his self-interests. Among them, they were usually relationships forged long before his development into the person he is today. For instance, with Raian, it is a friendship that can be traced back all the way to when they were children training with Shōyō. Over the course of his lifetime, he formed significant attachments with certain people, such as Shiori Miyamoto, and immediately came to love his children, Suzaku Kawahiru and Kaguya Kawahiru, once they were born. During his time as a Captain, he greatly cared for his subordinates, the ones who made up the fledgling Eighth Division; even viewing them as his family. Therefore, it cannot be said that Seireitou is incapable of real attachments, but that the nature behind his relationships are not so easy to decipher as to exactly how they formed nor why they are so precious to him. Because of this, some attachments he forms may seem superficial or built up based on absolutely nothing, and yet, Seireitou could still regard them as being crucially important. His reasoning behind helping someone or putting his trust into them may often seem fabricated out of nowhere, based on nothing concrete that others can empathize with, and yet his intentions are doubtless sincere. He could make a life-or-death decision entirely on a whim, leading people to believe he is truly insane, but Seireitou is not one to make rash decisions either. One could say some of his relationships are oft-born from his desire to observe the potential of those individuals who spark his interests, wanting to remain close to them so as to bear witness or to help them nurture it, though there is no way to draw any absolute conclusions regarding that. Above all, however, the relationship he seems to value most of all is the one between a teacher and their student; something that stems from his deep respect for his former master and caretaker, Shōyō. It is due to this admiration that, of the few things that ignite his rage, Seireitou cannot forgive someone who calls themselves a teacher and then abuses their role to take advantage of their student; especially if it results in their harm or a degradation of their potential.
- "A man that acknowledged the weakness within him and searched for strength within himself. Reflected in those eyes is not a wall standing in his way, but rather it is the wall called his 'limits'. It's not against his enemy, it's for the sake of breaking through his limits that he is fighting. He is always fighting with his strongest enemy... Himself. Whenever he goes up against an enemy stronger than himself, he overcomes those limits. And he always gets stronger, even right in the middle of those fights. No matter how high you tower in front of him, he will jump higher."
- —Saori Sumeragi describing Seireitou's nature.
Kamui Kawahiru has stated that Seireitou's most prominent quality is his will to surpass himself, striving to transcend his limitations, and never giving up even when the odds are stacked against him. His fighting spirit often borders 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 his own hand or because of other personal reasons. It can be attributed to the cynical realism of his personality, in which he has come to terms with the idea that in fights and wars, people die and that it is in the nature of a fierce battle for there to be severe losses. Seireitou seems to hold his own power in high regard, though he appears to bear no expressive signs of arrogance or overconfidence; admitting when he believes someone to be stronger than him or if the potential exists for someone, even among his students, to one day surpass him. Despite this, there can be no question that he is a monstrous combatant, wielding power that stands in a league of its own. But more so that that is the degree of confidence he possesses. This great strength often has a hand in his interest in facing powerful opponents, subsequently contributing to an inability to turn down challenges. This bad habit of wanting to test the heights of his strength against the most powerful adversaries means that he has no qualms about endangering the world or the lives of the innocent. Seireitou personifies self-confidence and self-assurance, believing that no matter how dire the situation, he can find a way to overturn the circumstances. His is a spirit that knows no surrender and always maintains faith in himself through any obstacle. No different than his emotions or thoughts being something that cannot be stolen nor swayed by an enemy, the faith he has in his own strength cannot be shaken. It is a will that has endured all manner of tragedy and despair, and through it all, has emerged more powerful than anything. Coupled with his bottomless stubbornness, he personifies a force of nature that will never accept defeat, and because of this, it is rare for him to ever experience a loss in battle against the same opponent more than once. However, it should be noted that Seireitou is, at his core, a pragmatist. If there should ever be a situation he personally considers unfavorable, it is possible he may even refrain from indulging in his battle-hungry desires. Also, often a habit displayed in battles, Seireitou refers to fighting from time to time 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.
There are certain frivolous interests that Seireitou often indulges in, such as his love of sake, sweets, and cuisine in the Human World; most of all, his tendency of engaging in carnal acts with women without any serious commitments. Nearly a century after the death of the only wife he would ever have, he went on to engage several different women from both the Human World and Soul Society in varying forms of deviant encounters; among them would include that of Rikuri Ukitake and Rangiku Matsumoto, the latter of whom he possesses a sort of casual relationship with.
- "An enigma like you, covered in blood, may think that he can follow the path of valuing life, but in the end, all you're doing is walking a path of carnage. You should understand... that you share the same fate as a demon. Everything you love, the people you cherish, and even those you despise... It will all be torn asunder. You will be the only person left in this world, Shiroyasha."
- —Warkiller speaking of Seireitou, after being killed by him.
By a combination of horrible circumstances culminating from war and personal tragedies, along with the influence of his malicious Zanpakutō, Hanullim, Seireitou had come to develop a sort of second personality that surfaced whenever he experienced intense moments of rage or despair. This persona is often designated as his 'Shiroyasha' self. While at first, he appeared to be completely unaware that he took on this sudden change, most likely due to being blinded by anger. Sometimes, this change would last for days, if not weeks or months at a time. It was the reason behind many of his vile acts during the Quincy Blood War.
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 the constant facial expression displayed by Kamui Kawahiru, 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 Shiori 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 hypotensive 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.
After his parting with Hanullim, Seireitou came to accept the Shiroyasha part of himself. Rather than casting it aside as if it were something foreign to his soul, he acknowledged it as an aspect of his own personality. As such, he adopted the brutality and malevolence that came with the Shiroyasha self, yet was no longer driven by those instinctive traits nor did he lose control over his own thoughts. He could finally make peace with that part of his soul, which only resulted in making him a stronger person, and led him down the path toward becoming a true Hakuda Grandmaster.
- "You have nothing to be ashamed of, that boy just happens to be a bit special. He's not like you, Raian-kun. Unlike your drive to protect your younger brother, Seireitou-kun does not have someone like that to protect. If anything, it was a matter of enduring for the sake of enduring. In order to live and in order to survive, that boy had no choice but to become stronger."
- —Shōyō describing Seireitou in his youth to Raian.
Born to Tsuyuri Kawahiru as a child of the Soul King, a phenomenon brought upon by the Divine Advent, Seireitou was the twin brother of Kamui Kawahiru. Unlike his brother, who had inherited not only the Soul King's power but also the birthright of the Sōzōshin, Seireitou was born with none of those special characteristics. In terms of lineage, he had only inherited Kitsune blood from his maternal side, along with a potent degree of reiatsu. At the moment of his birth, Seireitou was written off as 'a child never meant to have been born', for he was considered a failure who did not inherit the Soul King's power despite being his child. Because of this, when Kamui was taken by the Royal Guard, Seireitou was discarded to the Rukongai. Whether he lived or died was of no concern to them nor to his mother who was taken into their custody. He would have died out there if not for the survival instincts that kicked in, pushing him to survive on whatever little he could manage, even as an infant. Some souls in Rukongai would take him in from time to time, but they eventually abandoned him all the same when it came down to choosing between their own safety and that of a child that was not even their own. Whether it was by sheer luck or by the child's own refusal to die, Seireitou had grew up to an age where he could scavenge for himself. Most often, he ventured into scenes of recent massacres, in order to pickpocket corpses or to steal food from the houses of those who either were killed or had to abandon the village in question. He continued to live like that, gathering anything he could find in order to survive, even an Asauchi that belonged to a low-ranked Shinigami who was cut down by wandering vagabonds. That all changed, however, when he encountered Shōyō.
Although Seireitou was weary of him, even attempting to attack the stranger with the sword he had in tow, he reluctantly accepted Shōyō's offer to come stay with him at the village where he was living. It was a slow period of warming up to him, but Seireitou eventually came to view Shōyō as a father figure; something that was a new experience for him, given that the only caretakers he ever had were always people who gave him up at the first sign of trouble. This caused him to grow up in a very apathetic and reserved manner, keeping to himself and never opening up to others in Rukongai, despite Shōyō's efforts to push him toward forming connections with people. While living with Shōyō, he was taught how to read and write, and later learned how to fight and to wield a sword properly; eventually being taught formal Shinigami combat techniques, gaining a modicum experience in all four Zankensoki arts. While studying under Shōyō, who had often accepted other students, Seireitou would eventually meet Raian Getsueikirite for the first time.

- "Martial arts is a power that can bring people together, allowing them to understand one another in a way that is impossible by any other means. That is the beauty of this art. A weakness cast aside in hatred is no power at all. Rather, through the bonds made from experiencing and understanding others, you can strengthen your weakness and turn it into something powerful. With that strength, you inspire others to do the same, and the cycle of martial arts allows people to grow as the martial arts themselves evolve throughout the ages. This is the essence of martial arts. This is Hakuda."
- —Seireitou asserting his paradigm of Hakuda.
In The Brothers Kawahiru, Seireitou begins to settle into the peaceful married life together with Shiori Miyamoto, nearly ten years after the defeat of Myōken and Sydonay Senseirei. The two have been living in the nineteenth district of Rukongai where they have a moderate home and are raising their son, Suzaku Kawahiru. During a brief training session where Shiori was teaching Suzaku the basics of martial arts, Seireitou observing them closely, they are interrupted by the sudden appearance of multiple Shinigami that have been ordered to apprehend Seireitou on suspicion of being behind a recent terrorist attack on the Seireitei. Though refuting the claims, he agrees to go with them and meet with Captain-Commander Genryūsai Shigekuni Yamamoto. It is during a meeting with him and the other Captains that it is revealed the terrorist had a very similar reiatsu signature to that of Seireitou; according to Kirio Hikifune, the match was well over fifty percent.
The meeting is interrupted when shockwaves begin to rattle the ground like an earthquake. It is shown to be the cause of several Arrancar, many of whom Seireitou recognizes as being previously followers of Warkiller, along with a purple-haired man adorned in robes standing in front of them. He addresses himself as Kamui Kawahiru and states that he is Seireitou's brother. Though denying that to even be a possibility, the reiatsu match between them as well as his own claim to know nothing of his own bloodline beyond that of his Kitsune lineage, Seireitou attempts to attack Kamui head-on, though he is defeated with ease. While unconscious from the barrage of Kamui's destructive spells, the Arrancar that had accompanied him proceed to engage in battle with the Captains and other officers. Battlefields are drawn all throughout the Seireitei, and over the course of the fight, Kamui manages to ascend into the Soul King Palace. Eventually regaining consciousness, Seireitou tries to make sense of the situation at hand, leading to a couple skirmishes against the remaining Arrancar. He eventually encounters Yamamoto, who had just finished off several Arrancar with a sweep of his flames, and demands answers as to the identity of this Kamui who calls himself Seireitou's brother. Though claiming to not know much, Yamamoto explains to him about the Kawahiru Clan and the children of the Soul King; information that even Yamamoto himself had not know until recently. Declaring that he would move ahead to stop Kamui, Yamamoto reluctantly utilizes the Ōken that is bequeathed to the Captain-Commander so that Seireitou would be granted passage to the palace.
Finally making his way to the platform of the Soul King Palace, Seireitou is surprised to see an unfazed Kamui standing before the defeated Royal Guard members. After a brief conversation in which Kamui provides some exposition on his motives, the two proceed to battle, with the skies lightning up and the palace cities trembling in the wake of their attacks. It is during this battle that Seireitou reveals his trump card: the Izanagi, which he developed through his training under Kachōfūgetsu. However, even with the might of this ultimate technique, neither side appears ready to fall. They both unleash vicious attacks on one another, and during their exchange, Kamui appears stunned with the thoughts of his past and the brief moments he managed to see Seireitou when the latter was but a newborn and Kamui himself was a young child. Distracted by these visions, Kamui is overwhelmed by Seireitou and subsequently surrenders; promising that he would return one day to settle this conflict between them, before entering into a portal and leaving. The battle-worn Seireitou descends to the Seireitei where he learns that the Shinigami have vanquished the last of the Arrancar and proclaims that Kamui retreated after declaring surrender.
- "Back then, I only cared about protecting two things. But I was forced into a situation where I had to pick one. I tried to save both, but it was no better than throwing them both away."
- —Seireitou speaking of Shiori and Suzaku, his late wife and estranged son respectively.
In the Thousand-Year Blood War, unbeknownst to Seireitou and Saori at the time, the Wandenreich waged their war against the Soul Society; first by invading the Seireitei, leaving much of it in ruins upon their retreat, and second by returning to kill the Soul King as well as finish off the Gotei 13. The death of the King by the hand of Yhwach caused tremors to rumble all throughout the Soul Society, which was immediately picked up on by Seireitou and the other Masters of the Senjukuha. Being born of the Soul King, Seireitou could recognize what the cause behind the earthquakes was, subsequently making plans to head back to the Seireitei along with Saori and Rinnōbō Yoshioka. Of course, upon arriving, they found it almost impossible to penetrate the barrier shielding off the Seireitei — now occupied by Silbern — which made it nigh impossible for them to enter the fray and get involved. As luck would have it, however, the battle was not to last too much longer, as once the final defeat was issued to Yhwach and the end of the war came, the barrier had also come down to reveal the devastated Quincy buildings which were slowly receding back into the Seireitei structures. In his inquiring of the events that had transpired, Seireitou came to learn that the Soul King, who was essentially his father, was killed during the battle. Though Saori and Rinnōbō offered their condolences, Seireitou shrugged them off, remarking that the Soul King was never anything resembling a father to him. Similarly, his mother Tsuyuri met her end to the hands of the Quincy invaders when the Royal Palace was overtaken, but Yukina managed to survive.
In Opposition against the Shiroyasha, Seireitou faces off with a multitude of opponents looking to test their might against the Hakuda Grandmaster.
- "Would you quit blabbering? You bastards sound like dogs in heat. By all means, keep yammering, but I'm just going to tune you all out."
- —Seireitou defending Minato Kuramoto from a band of Arrancars during their first encounter.
- "Don't waste your time trying to understand me, you still have work to do. Your disciple can still become stronger. However, he could go the wrong way, like I did. Hopefully, he will listen to you... the way I could not."
"This is the end for you... and the only words you have are of concern for the son you abandoned?"
- —Hōsen Kuramoto and Seireitou after the former's death.
In The Darkness Cometh, the existence of the L'Obscurité threat had become far more apparent that it was determined that actions needed to be taken. Learning of their intentions, Seireitou and the other masters of Senjukuha held a discussion between the five of them. Seireitou often tried to isolate himself from matters he had no personal interest in, even if it meant destruction of the world would be a consequence of his negligence. However, among those that Mūkade listed as the members of the organization's head, the Ikken Kyūkage, a member by the name of Hōsen Kuramoto immediately caught Seireitou's attention. He confirmed the suspicions that he was in fact the father of Minato but it was clear that he had something personal invested in this particular individual, which even Saori did not know. Leaving it at that, it was a situation that the Gotei 13, still trying to rebuild its ranks after the war against the Wandenreich, would simply be unable to handle on its own. Therefore, it was agreed that they would take the information they obtained from Mūkade and make the first move themselves so as to bring the Ikken Kyūkage down. They had also agreed to keep the plan secret from Minato and Hinata, though Minato had overheard the plan from outside the walls.
On the morning they prepared to set out, Minato confronted Seireitou and the others about their intentions and demanded that he come along with them. However, Seireitou told him it wasn't his time to fight an enemy like this, and that he was best to defend the dōjō along with Hinata while they were away. Although reluctant to agree, Minato nodded in response. Making their way into the Dangai world, Saori and Rinnōbō utilized their abilities to locate the exact coordinates where Mūkade told them to look and managed to discover the hidden Kyōgoku there. They proceeded to forge ahead with a path and broke into the space that concealed the organization's headquarters, Susuki Castle. Of course, it was not as much of an infiltration as they would have liked, as their presence was almost immediately picked up upon by the members of the Ikken Kyūkage. According to Mūkade, the leader went by the name of "Kurama" and the goal was to take him down.
Going their separate ways in pursuit of the determined plan, Seireitou made his way for the east corridor of the castle and made his way down the hallway. He picked up on the spiritual pressure of his fellow comrades and the battles they had just engaged themselves in, only to run into Hōsen Kuramoto. The two hold a brief conversation, in which it is revealed that Hōsen was actually the first student Seireitou ever took on, back before he had even become a Captain and still served as one of the two leaders of the Wolves of Yoshida. Unable to guide the young Hōsen due to the fact that Seireitou simply had not the skills at the time to serve as a good teacher, Hōsen was disillusioned by the notions of peace and tore away from him. Seireitou regarded Hōsen as his greatest failure as well as one of his greatest regrets. In a strange shift of topic, Hōsen asked if his children were still doing alright; referring to both Minato and his older sister, Takara Kuramoto. Seireitou answered simply with a nod before Hōsen initiated the offensive. The two of them engaged in a series of fist to fist clashes with the ground beneath them shaking under the force of their attacks.
The battle would soon be interrupted by the appearance of Minato, who, along with his team and Hinata, followed them and used the portal left behind by Saori and Rinnōbō. Minato demanded to know if it was true, that Hōsen was indeed his father and that he did abandon their family all those years ago, to which Hōsen confirmed with a casual remark. Enraged, Minato attacked Hōsen, only for the former's strikes to be swatted away. In the midst of his aggressive assaults on his absentee father, Seireitou took advantage of an opening and struck down Hōsen with a violent attack to the chest, as the latter fell to the ground on his back in defeat. Minato lashed out in anger at Seireitou, stating that it was his duty to take revenge on his father for what he did, but Seireitou retorted by explaining that it was Hōsen's intention to fall by his own hand. He went on by explaining that Minato was far too young to have allowed his hands to be bathed in the blood of vengeance and that Hōsen being killed by Seireitou in front of Minato while the latter seethed with hatred was the best option in order for Minato to move on without having committed such an act. Seireitou went on to say that he and Hōsen agreed to this, revealing that he knew that Minato would follow him and the other masters. With his dying breath, Hōsen spoke with Minato and expressed his remorse that he was unable to find a better way to approach the situation. Despite the fact that Hōsen contributed to the plan made by L'Obscurité, he tried to break ties and even managed to form a family before being forced back into their ranks, lest they threatened to kill Hōsen's newborn child and young daughter. Seireitou then demanded Minato leave and return to his team who needed him right now. Though reluctant, Minato agreed, leaving behind trying to hold back his tears. In Hōsen's final moments, he asked his former mentor to take care of his children and to continue serving as Minato's instructor.
Seireitou continued to advance, eventually crossing paths with Botan who managed to defeat her adversaries a little while ago. She said that Kuniharu, Rinnōbō, and Saori were still locked in battles across Susuki Castle, but she went forward once she picked up on the one they believed was the leader. Wasting no time, the man known as Kurama Kawahiru walked down the long flight of stairs leading up to the next level of the palace and stared down the two martial art masters. Experiencing flashbacks from the time he faced Datara Kawahiru, Seireitou ordered Botan to leave him to Seireitou, as he did not want a repeat of the moment when he lost his beloved wife. Agreeing to leave them, Botan exited the room to provide help to the others, as Seireitou and Kurama began their fight. Both stood as Grandmasters of the Hakuda craft and their battle reached a level of intensity that forced them to break straight through the roof of the palace as they ascended to the skies above. During their match, Seireitou came to learn more about the motives behind Kurama's plans and the purpose behind L'Obscurité, but regardless of the reasons, Seireitou was determined to win and put an end to the pain that was inflicted onto his former student and his current student. Though the two seemed evenly matched, Seireitou took the lead when revealing the unique nature behind his perfection over the third realm of Hakuda, Kihaku. Though the battle continued to be hard-fought, the conclusion of the fight eventually came with Seireitou's victory and the annihilation of Kurama. Though this was cause for celebration, one of the remaining members of the Ikken Kyūkage, Yáng Zhū, set into motion a spell that was designed to essentially self-destruct the entire Valley of Screams where Susuki Castle was based. As the dimension slowly began to crumble away, the masters as well as Minato's group and Hinata managed to reach the spot where Saori and Rinnōbō prepared the portal for a return to the Soul Society. All that was left was for Seireitou to reach that point, but on his way there, he was stopped by Seimei Abe, who thanked him for putting an end to Kurama's nefarious plans. However, Seireitou rejected his gratitude, stating that his only reason for coming here was to settle a past problem, obviously referring to Hōsen, and that Kurama "just happened to be there". Shrugging off the remark, Seimei turned away and replied that their paths would cross again, as Seireitou paid it no heed and went off to escape the collapsing dimension with the others.
In Served Cold, the enigmatic bounty hunter known as Vengeance challenged Seireitou in order to kill him on the part of multiple clients that desire the Shiroyasha's death for the crimes he committed in the past.
- 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 Senjukuha; however, he did at one time claim that he threw it out after "spilling hot miso soup" all over it.
- Seohak (천주학 (睿智天の原), Sōhaku; Korean for "Heavenly Learning"; Japanese for "Wisdom of the Heavens"): The Zanpakutō of his mentor and grandfather, Shōyō, Seireitou procured the blade after his master's death and has kept it within the confines of his own school 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
"What is this... abysmal feeling? I can see the exorbitant spiritual force emanating from his person. His entire body is illuminated with an intense white aura, carrying with it such strength that it threatens to swallow up the entire land around us... When I attempt to feel out his power, I already know the promise of death such strength represents. But despite the immense power I can feel out, there's an eerie calm to it. At the same time as I can assess the danger, it also feels like nothing is there; as if there isn't anything that could pose a threat. Almost as if... it were the essence of nature itself."
By his standing as the founding 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 over a thousand years ago, 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 many of the older Captains of the Gotei 13 believe that no one of the current generation will be able to surpass him, and that he has become equal to his teacher, the legendary 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. By the standards of Otoya Kurogane, who has managed to discern the relative power level of even the strongest that the Soul Society has to offer, Seireitou's own power stands in a class all its own.
Transcendent Spiritual Power: As one of, if not the strongest Shinigami alive, Seireitou possesses absolutely monstrous spiritual power. He is a being that has achieved the state of a Transcendent, and as such, he stands in a class akin to that of Yhwach and the Sōsuke Aizen after the latter's fusion with the Hōgyoku. In terms of coloration, Seireitou's reiatsu is a pure and dense white, invoking the scene of a blizzard that has been raging violently for centuries. His reiatsu has been likened to the 'weight of the skies' boring down on a person, possessing the potential to collapse their very soul onto nothingness. Perhaps due to his Kitsune origins, Seireitou's reiatsu has been known to take on the appearance of a fox head, bearing vicious fangs that threaten the life of any foe that dares stand before him; his presence alone tends to crush the breath out of even the most skilled warriors. During the Quincy war, Seireitou was called 'Shiroyasha' due to the simple fact that he resembled a true demon on the battlefield. A reiatsu of white falling onto the land like rain, instilling a deep sense of terror and despair onto the enemy army, as his reiatsu itself would serve as the first waves of attack while the Shiroyasha himself followed shortly after with an absolute onslaught of force. With such density, it can be compared closer to that of an Arrancar than that of a Shinigami, with his reiatsu being capable of disrupting attacks of spiritual energy composition from considerable distances, even miles from where he physically stands. After abandoning his position as a Captain, Seireitou had ventured into the Beast Realm where he continued to temper himself, gaining even greater strength than what he possessed as a mere Shinigami. It was there that he learned of his Kitsune lineage, learning how to wield his innate powers, but more importantly, it was during that time that he trained under the ancient spirit, Kachōfūgetsu. Seireitou's reiatsu had not simply become far greater in nature, transcending power itself, but had also acquired a peaceful and life-giving quality to it. No longer was he simply a monster of brutality but an entity of balance; holding both life and death in his hands, as a true god of death should. It gained a rather peculiar characteristic of being simultaneously immense and powerful but also harmless and tranquil. The same power that could smother the life out of any opponent could also not so much as harm an infant. His reiatsu, refined through Kachōfūgetsu's teachings, was able to breathe new life onto the world around him, even causing plants and flowers to bloom. This could even influence other living beings around him as well, enabling Seireitou to provide basic healing simply by the transmission of his own reiatsu onto them. As a Transcendent, Seireitou's reiatsu had reached peaks where it no longer manifested in the traditional sense, rather resembling a coat of shimmering white energy of nigh mystic features. While his energy can still be felt by those allowed to interfere with him, the sheer bottomless nature of his strength is such that it may as well be considered immeasurable. Many who have tried to gauge the depths of his power only find themselves being lost within the embrace of its vastness.
- "With just a single breath, that man could snuff out every life near him if so inclined. Every step he takes is like a tiger walking across a room of rabbits. They know by instinct to fear him."
- —Bianca Sayuki remarking upon Seireitou's fear-inducing strength.
- Mental Interference: Seireitou's reiatsu carries such a tremendous intensity about it that it can induce feelings of terror within those who are unfortunate enough to get close enough to him. 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. An opponent who looks upon the powerful entity that is Seireitou may find themselves lost in the sight of a massive kitsune visage, which is the personification of the silver-haired warrior's power. But this is but the surface; the manifestation of the man's most tame energies. 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. Raian Getsueikirite had often referred to this tendency of his as the 'white curse', in which his reiatsu quite literally has an effect alike to that of a curse bestowed onto those unfortunate souls that are subjected to his terror-inducing spiritual pressure. 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.
Fox Transformation: Seireitou was born of Kitsune blood; a lineage he only discovered after making a pilgrimage to the Beast Realm. While he lived with the Kitsune tribe, he learned how to invoke and cultivate that aspect of himself, which led to him developing the ability to shape-shift into a fox at will. When Seireitou is in this form, he boasts snow white fur and a single tail, though there are moments when he reveals all nine of his tails; usually for the purpose of intimidation. He can control the size of his fox state, ranging from a small cub that could sit atop a person's shoulder to a large ferocious beast that can tower over adult heights. In fox form, he can channel his reiatsu and fight without hindrance, albeit in a bestial manner. Of course, while in this form, he only wields a mere iota of his actual physical capabilities. While he is in this form, his reiatsu becomes completely like that of a Kitsune, and thus, it provides him with a perfect disguise as it becomes impossible to recognize his own reiatsu from that of his fox self; unless someone was already aware of this form and its characteristics, such as Raian Getsueikirite or Saori Sumeragi.
- "It's Seireitou-san, hands down. You saw what he did today, right? That total rampage he went on? The boldness he had in that surprise attack on the Quincy? That utterly demon-like fighting style that even the warrior clans of the noble houses can't even come close to? None of our enemies or allies can beat that guy."
- —The first Eighth Division generation commenting on their Captain's strength.
Immense Strength: Perhaps due to years of combat experience and time on the battlefield, combined with his centuries of sheer Hakuda mastery and specialization, Seireitou has a tremendous degree of physical strength; most commonly displayed by his ability to fight on par with some of the strongest beings within the three realms with naught but his bare hands. 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. He is like a piece of steel itself. Resilient and impenetrable, Seireitou's durable strength is so great that it is almost impossible for any blade to cut through his body nor to pierce it efficiently. 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 physical durability is often likened to the Arrancar's hierro, which compresses their reiatsu for the purpose of providing them with a hardened skin that will protect them from enemy attack. 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, coupled with his tremendous physical strength, this allows 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 a god-like level. During this time, one finds it impossible to feel his 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 Kawahiru as a martial artist is what protects him from the attacks of his foes. The sheer magnitude of his 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. The mere thrust of his hand is enough to impress the very shape of Seireitou's hand onto any surface that may be within the range of his strike'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. These become physical strikes that can be used to completely demolish victims before Seireitou, effectively conquering all that lay before him. 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 aforementioned 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 brute force. Such overwhelming volumes of strength absolute has enabled Seireitou to perform nigh unrealistic feats, even tearing apart Bankai with his bare hands.
Hyper-Speed Combat: As a Hakuda master of unrivaled power, Seireitou has refined the art of movement, performing natural footwork that implement the teachings of Shunpo, Hirenkyaku, and even Sonído. His body movements appear as mere blurs, if anything else. 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; developing an almost god-like speed that even most Reikaku have difficulty following. With his arsenal of Hakuda strikes, his speed at the utilization of these aforementioned techniques is beyond normal comprehension, with most movements resembling something akin to magic. 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, his 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. His speed 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 those who utilize Shunpo. Through those aforementioned teachings, he can nigh infinitely accelerate his steps while maintaining swiftness, agility, and control; shown by his ability to invoke himself into high speeds as if it was second nature, despite the tendency for other users to end up with their legs broken due to inexperience. With such movement speed, he can easily match and possibly surpass the speed associated with Shunkō. These rapidly-increasing steps cause multiple sounds to occur, in contrast to normal stepping movements which produces a single light sound. By accelerating his 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. But through his self-control, he is able to muffle the sound of his movements if need be so as to remain undetected by most opponents. 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. Rather than using any particular Hohō technique, he adopts the concepts of those various movement skills onto his own natural footwork. One particular instance of this was when he took to studying the Quincy technique, Hirenkyaku. He had 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, Rūka Ishida noted that Seireitou was "moving less like a Shinigami and more like a Quincy"; demonstrating that he can not only combine the techniques together but also shift between the method on a whim. Some time after, he also implemented Sonído, and in doing so, his movements that were instantaneous and swift through the previous two techniques could now also allow him to vanish from an opponent's reikaku, just as the Arrancar could do. This, of course, all would eventually lay the foundation for the movement of Shintai Seiatsu; elevating Seireitou's own movements beyond human ability and therefore something that could no longer be comprehended as such.
- "When you trace back the branches and leaves, reaching all the way back to the roots becomes possible. Not to remain fixated on the result but rather to allow yourself to flow back to the origin, that is when you will start to understand it all."

Tremendous Insight: Despite his laid back attitude, Seireitou has repeatedly shown himself to be a perceptive and insightful man; being significantly detail oriented, in both fighting and in life. He wields a wisdom reflective of his experiences, one which often becomes disregarded by many due to his erratic and intentionally irresponsible behaviors. It is often considered impossible to hide anything from Seireitou, with his insight capable of penetrating deep into the core of a person's psyche, allowing him to recognize their mannerisms and nature, when something may be troubling them, or even if their words carry lies hidden among them. There are times when it almost feels like he can literally read minds, knowing exactly what a person is thinking in a given moment; even to the point of scaring those who listen in on his own thoughts, which is sometimes portrayed in a comedic light with his student Minato Kuramoto. His understanding of human nature and the vast degree of individuals he has encountered throughout his lifetime has made Seireitou into something of a sage when it comes to people, their behavior, and even their emotions; such familiarity enables him to offer meaningful and impacting advice to those lost in their ways. In battle, this insight becomes one of his most valuable armaments. Seireitou notices his opponent's mannerisms and discerns with ease the reasons behind those actions and the weaknesses and strengths of his opponents. He 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, proving himself to be quite the crafty tactician from how easily he can deceive both allies and enemies. Seireitou possesses an undeniable skill in analyzing and observing everything in his presence, allowing him to quickly understand a person's pattern of thinking to better manipulate them or to become aware of any potential danger before it reveals itself. 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 regarded as being highly intelligent, capable of devising and executing strategies with incredible speed and precision. He has repeatedly demonstrated just how perceptive and analytical a warrior he can be from how quickly he can analyze an opponent's power and attack patterns to ultimately make them useless against him. Seireitou 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 in two instances in his fight with him. The Shiroyasha is very resourceful, able to use a wide array of unorthodox tactics to accomplish his goal; utilizing means that may sometimes creep into the immoral. Through his heightened level of perception as well as the tremendous degree of experience he has acquired throughout his lifetime, Seireitou is able to recreate and reconstruct skills and techniques based upon very little knowledge gleaned from his experiences. It is through this that Seireitou uncovered the secrets behind many ancient martial arts that were thought to have been lost to history for centuries by only going off minimal available information about them. Of course, while this is debatable as to whether he has recreated accurate accounts of those lost arts or not, it was stated by an old master of a long forgotten martial art style within the Soul Society that it would be impossible for Seireitou to have known how to execute one of the advanced techniques from his style when he himself, who had invented the style, had not taught anybody in several centuries. He has shown himself highly capable of figuring out the mechanics behind advanced techniques within many martial art styles by only observing the style's basic fundamentals and then putting together the most logical outcome that would result from continued mastery of that style. It is through this that even if he is unfamiliar with the skills of somebody seeking tutelage under him, it would not take very long for Seireitou to devise the best method to further that individual's skill. He can even notice the unnecessary and obsolete techniques that may exist within an individual's style and formulate a more condensed form that significantly enhances its efficiency as a fighting style. 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; utilizing drastic albeit effective strategies to overturn the situation in an instant.
- Battle-Forged Visual Nullification: Unlike his brother, Kamui Kawahiru, or that of Yhwach, whom were all born as offsprings of the Soul King, Seireitou did not inherit the same future-telling abilities associated with their unusual double pupil eyes. It was through several centuries of training and experience, in having mastered the discipline of Hakuda Zanshin, that Seireitou eventually came to develop what is best regarded as battle-forged precognition. According to Kyebaek Tae, those who have fought in various life-or-death matches cause those who survive to develop a unique form of clairvoyance that comes about from an almost superhuman level of perception. However, what Seireitou has developed from his years of battle goes far beyond even that degree. His precognition derived from his experiences allows him to anticipate and instantaneously perceive the intentions and movements of his opponents effortlessly. He merely needs to register an opponent in thought alone. From observing their stance, he can immediately glean the knowledge of their potential physical movements that they can possibly take in their next action. Derived from the sight of their existence, the feel of their presence, the smell of their bodies, the spiritual power radiating from their center, the smallest twitch in their expression or body movements, the acknowledgement of their emotional state, and even beyond that; a cornucopia of knowledge and information that rivals the power of Yhwach's "The Almighty" and Kamui's inherited abilities; making it possible for Seireitou to render almost any power he comes across useless the moment he faces it in combat or even experiences it from the sidelines.
Konsō (魂葬, Soul Burial): As a Shinigami that has unified with his Zanpakutō, Seireitou is able to perform the Konsō ritual without the need for one. He is able to perform the technique simply through his own hands, often doing so by placing a finger atop the soul's forehead and imprinting the seal through his reiatsu onto them, so as to send them off into the afterlife. Similarly, by channeling this power through his reiatsu and coating his body with it, Seireitou can also cleanse Hollows with his bare fists rather than requiring a Zanpakutō to slay them.
- "If all you do is strike, you still have not truly exchanged blows with your opponent. When engaging the opponent in battle, you must reach out and touch their heart. Otherwise, it is impossible to threaten your foe's life in the true meaning of the word. "Mind, skill, and body." All martial arts share this concept. Through the martial arts, you aim to learn about your foe while also to understand yourself. It is essential that it comes from the heart."
- —Seireitou's belief in battle and his teachings of Hakuda.
Among the four Yonkō, Seireitou is known as the respective master of Hakuda; the Shinigami system of hand-to-hand combat. He is regarded as having completely mastered all aspects of the martial arts, and in doing so, he has achieved complete mastery over his own being. Even among other Hakuda Masters who have consistently demonstrated extraordinary feats of strength, speed, and technique, Seireitou still stands in a class of his own when it comes to the martial arts; having shown himself capable of effortlessly defeating even those the world would regard as standing among the best of the best. His unrivaled level of Hakuda has earned him the highly sought-after title of 'Grandmaster' within the 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, thus having achieved absolute martial condition. His skill has garnered a legendary status among others who also are considered of the Grandmaster class, going as far as to be often referred to as the "God of Martial Arts" (武道神, Budōshin; literally meaning "Martial Arts God"); a status that many seek to seize from him. Ichibē Hyōsube, a powerful entity in his own right, once commented upon Seireitou's unrivaled and almost godlike Hakuda prowess, remarking that he is "not just a martial artist, but rather is martial arts itself — an absolute force of nature."
General Hakuda Prowess: Known throughout the land as the Hakuda Grandmaster, as the one who has mastered all martial arts and the way of the self, Seireitou's Hakuda stands in a class all its own. It is not a matter of debate nor one of personal opinion. Over the course of his lifetime, he has faced all those who boast incredible talents and martial art skills, those who have been honored as masters and sages, those who have mastered the heights of martial art technique, and yet, he managed to defeat every single one of them until there was nobody left to fight. Until there was nobody left to oppose the statement of Seireitou Kawahiru as being the authority of martial arts themselves. Therefore, to call him the champion over all Hakuda specialists is not a thought nor a belief, but akin to a law of nature; an absolute statement. Something that simply cannot be disputed. For this man, it is an act to be considered truly frightening if he were to so much as raise a single finger with any intention of striking at an enemy. 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 phenomena that resemble divine intervention; that have reached such perfection that they can be considered a true zen of martial arts themselves. 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. It can be said, therefore, that one such as Seireitou possesses a caliber so tremendous that the reach of his arms and legs form something akin to a barrier; anything that would enter this space, this sphere of influence, would be shut down instantaneously without fail. If he is to so much as a lay a single finger upon your body, the fight would be over. Defenses would be neutralized, center of gravity compromised, stance destroyed, and the entirety of their existence vulnerable onto utter decimation; all in the same instant as they attempt to somehow understand what had just transpired. 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 strikes. According to Raian Getsueikirite, 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.
Unrivaled Fighting Spirit: In spite of his vast degree of strength, speed, and skill, Seireitou was recognized as the Hakuda Grandmaster first and foremost because he alone possesses the strongest 'fighting spirit' (闘気, tōki) of any warrior. A will that is driven by a reason, whether an aspiration or a person, is one that is dependent on that source. The tenacity of that will is proportional to the nature of that reason and to the degree at which that aspiration is carried out or that person is protected. But such a thing can not be considered authentic. While one's will can be reinforced by the presence of others or the existence of ideals, its true strength only comes from within that person, and nowhere else. "I fight because I want to." That's all it is for Seireitou Kawahiru. It is born from nothing more than the will to fight and train for fighting and training's own sake. He is not someone that becomes stronger nor trains to become stronger for the sake of another, but rather, he is a warrior that fights solely through his self-interest. It is a pure desire that is not tainted by the notions of victory or defeat. As a martial artist, in both the vein of a warrior and a teacher, he seeks the evolution of his skills and the martial arts themselves out of nothing but growth for growth's own sake. The true martial artist is not concerned with winning or losing, of living or dying; to them, the battle is everything. An independent fighting spirit that stands as an indomitable pillar all its own can never be toppled over, for the very idea of falling over does not exist for it. This unbridled and solitary existence of absolute fighting spirit manifests itself in the Shiroyasha's most fearsome attribute; the ability to adapt to an opponent(s) at a rate that is considered almost unrealistic. Ironic for one that is not concerned with victory or defeat, it is because of this nature of his that Seireitou almost never loses to the same opponent twice, if not once at that. One infamous instance of this, in a battle over a millennia ago, that could be said to have been the birth of the Hakuda Grandmaster of Soul Society, is the fight between Seireitou and the former Hakuda Yonkō, Yukara Shihōin. Initially overwhelmed by the rate at which the latter's power was increasing throughout their fighting, Jinsuke Kuchiki, who served as a witness to the fight, 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. He would go to remark upon how monstrous an individual that Seireitou had to be to adapt and improve at such frightening rates, despite the grievous injuries he was sustaining at the same time. That is the greatest strength of Seireitou Kawahiru, the White Summit, whose unrivaled tenacity and will becomes strength itself, and just as his will knows no bounds, so too does his physical strength reach limitless plateaus. His power is absolute in that it seems to be a never-ending reservoir of unimaginable depth. It is a strength that has allowed him to fend off the forces of nature that even the greatest of beasts fear, ripping away that which cannot be touched — thoughts and concepts themselves — while managing to resist forces with his bare hands that no mortal could ever hope to stand against; reaching absolutely limitless peaks so long as the silver-haired master's spirit continues to fight. Only someone who had abandoned victory, one that had abandoned the promise of escaping this battle alive, could have been improving themselves in the midst of such life-or-death situations. This is simply not a man that can be defeated by delivering a critical blow nor inflicting some kind of grievous wound, for his indomitable will surpasses even his own survival instincts; his fighting spirit spits upon laws of nature themselves and allows him to leap over the abyss of death. Such a spirit makes him one of those rare few, such as those imprisoned in the Muken, who possess hearts that are incapable of being stopped regardless of the circumstances.
Mastery of the Self: The foundation of Hakuda, and of all martial arts in general, is predicated upon mastery of the self; that is, to say, command of the mind, body, and soul, in order for all three aspects of self to function as one. From every external and internal part of their body to the deepest regions of their mind and soul, all things are within the realm of control for a true Hakuda master. Seireitou, as one who is called Hakuda Grandmaster, is a being that has achieved true oneness of self, having managed to even go as far as to achieve absolute self-mastery. His mind, body, and soul are entities that can not be taken; they can not be conquered through any means other than outright decimation of his very existence. He is capable of controlling his own state of existence. On a physical level, this means Seireitou is able to manipulate and control his body in any manner he may will it, including overwhelmingly impressive feats of flexibility, adaptability, and acrobatics. 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. Seireitou is even able to control his own internal workings, restructuring his own nerve signals on the fly; even going as far as to completely recreate the natural behaviors of his organs, muscles, nervous system, and blood flow on a whim, among other internal functions. All of this translates to his unique ability to move and fight in ways that the human body, or even a Shinigami body for that matter, is unable to accommodate. Seireitou's Hakuda is not built with the human body in mind; to mimic his movements to any proficiency means to also restructure the same nerve signals he has changed inside his own body. The key principle of movement within the martial arts is to have control over the mind and body, to an extent that it becomes possible to unify their passive and active intentions so that the body moves with thought as opposed to at different intervals. When these two are in dissonance, not only does the efficiency of the martial artist's actions fall behind, but they can be easily read and predicted by an opponent during battle. It is through Seireitou's absolute mastery over his own self — mind, body, and spirit — that every part of him moves in unison and acts in any manner he wishes. Of course, for most masters, this requires concentration and being rendered off-guard can cause the unification of mind and body to collapse. However, for Seireitou, the act of moving in unison is second nature to him, such that he does not require a conscious effort to keep control of every aspect of his being.
- Age Manipulation: By controlling the base of his own existence, through the self-mastery that is developed through Hakuda, Seireitou is able to manipulate the age of his body and subsequently alter his physical appearance. His preference appears to be taking on the form of a child, right on the cusp of pubescence. While in this state, his hair also recedes considerably, with it only draping along his shoulders. Much like in his fox transformation, Seireitou can still channel his powers in this form but he is significantly limited in his capabilities. However, he is noted as being quite swift and agile in this smaller state. He often adopts this form either to blend in with people in the Human World or to avoid being recognized in the Soul Society. Seireitou is known to also use his child form to spar with his Hakuda students, deeming the weakened power of that state to be sufficient in serving as a sparring partner for them. Despite this, even as a child, he harbors considerable strength; enough to combat most Shinigami in the Gotei 13 with ease.
Master of the Martial Arts: Over the course of becoming known as the White Summit that towers over all Hakuda masters, Seireitou had come to master countless martial art styles; achieving a command of Hakuda that has since never been contested to this day. Much like the infamous Yachiru Unohana, said to have mastered all swordsmanship styles, Seireitou is such that it would not be inaccurate to say that he has mastered all martial art styles, even among those thought lost to history. Whether they originated from the past or were codified in the modern age, Seireitou possesses them under his belt. In addition to those countless styles that have been mastered, Seireitou has had a hand in the creation of several techniques and styles himself; some which remain unique to him and others he put together solely to teach certain individuals, believing such a style would be bested suited to them. Each of those styles reflect some measure of Seireitou's own beliefs and unique teachings. He generally uses these creations to properly train those under his wing, with the shining jewel of these efforts — the Shōin Shiranui Style, in other words — being reserved only for those students that have impressed him and interested him the greatest over all others seeking his guidance. However, that is not to diminish the value of the other styles that the silver-haired master has created, for each of them had been designed to teach a fortified and concentrated system of martial arts tailored to specific strengths. 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; mainly a result of their lethal nature. 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. It is stated by Hōsen Kuramoto 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 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 a 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. In addition to this reserve of never-ending knowledge of martial art styles, due to his years of experience, he can copy any martial art technique of even the greatest of master-class fighters, no matter how unique it is to the opponent, which has helped in the development of his personalized fighting style.
Instantaneous Style Creation: Throughout the ages, techniques and methods have risen in an attempt to create a perfect martial art style, weaponizing the body in a manner no different than the blade of a swordsman or the spell of a sorcerer. However, upon reaching the zenith of Hakuda, one eventually realizes that it is unnecessary to master techniques nor styles. True mastery of the self — in other words, a genuine mastery over Hakuda — is demonstrated by the ability to develop techniques on the fly, styles that rise and fall like the sun and the moon, when their need arises, and once they have served their purpose, they are forgotten. The Hakuda Grandmaster is one such martial artist who can produce hundreds upon thousands of martial art techniques, forms, and styles in the midst of fierce battle; all derived from immense mastery and knowledge, yet all abandoned in the wake of his natural integration of martial arts themselves into his core. He is like water, his actions take shape as the circumstances demand just as water takes a form depending upon its container, and as the situation changes, his actions change to reflect those occurrences. By this innate skill, Seireitou is at a level where he is deserving of the status of 'Takemusu' (武産, meaning "to give birth to martial arts"); one that contributes to the martial arts, rather than simply learns from them. Achieving a mastery of his level renders the study of techniques themselves as insignificant, for Seireitou is the very embodiment of martial arts, and can therefore spontaneously use and create martial art techniques for any given situation during the heat of battle. A technique is created for that moment, and then forgotten in the next, for there is no need to hold on to that transient existence for a greater technique can be created in the same manner when the demand for it is presented. Rather than needing established techniques or styles during a fight, Seireitou invokes the concept of what those techniques are built upon of which he is himself overly familiar with, acting in whatever manner may be demanded of him in a given situation.
Knowledge of the Body: Drawn from this immense knowledge of the body acquired through battle experience, including that of its anatomy, Seireitou demonstrates a vast degree of insight into how both physical and spiritual bodies work; how they move, how they behave, how they are structured, and ultimately, where one can find its weaknesses. Such knowledge becomes an instrument in which Seireitou exerts his Hakuda so as to physically control the bodies of his own opponents, making it possible for him to dislocate and manipulate the joints of his adversaries with ease. He is known to expertly break certain joints with such swift movements that the opponent hardly recognizes the injury until it becomes pointed out. This is demonstrated by a 'bad habit' Seireitou 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. Despite being a generally consistent proponent of peaceful resolution against an opponent, the methods of which Seireitou manipulates (usually resulting 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. 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. Such skills are attributed to Seireitou's ability to recognize the weak point, or vital point, of his target, in order to manipulate those joints or pressure points. By aiming for key meridians of the opponent's body, via palm thrusts, Seireitou can alter the course of reiryoku flowing around the opponent and through the opponent, essentially weakening their subsequent counterattacks or chances of continuing the fight while also weakening the flow and stability of their reiatsu; an act quite fatal to beings such as Arrancar, who are known for the use of their dense reiatsu. 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.
Mastery over Hard and Soft: When it comes to the martial arts, they can be divided into two categories: 'hard type' and 'soft type'. Most martial artists generally fall into one of these two types, but for someone at Seireitou's level, he has mastered both types to such an extent that he can employ both of them individually or together in frightening applications. By its very name, Hakuda is an art that centers on striking methods; the 'hard type', which focuses on direct combat as opposed to indirect interaction. Of course, the name is fundamentally misleading, but it is definitely true that martial arts is founded upon the idea of conquering one's adversary. Thus, to overwhelm the opponent and subdue them, perhaps even to the point of taking their life, the body of the martial artist must be forged in such a way that it can attack with sufficient efficiency to produce those results. When Seireitou strikes in such a manner, it is possible for him to deliver a blow akin to sending forth earthquakes reverberating through the body of his victims. Even if the body appears unharmed, tremendous internal injuries can be sustained within an instant. The nature of these strikes is disruption in every sense of the word. Seireitou's hard-type Hakuda allows him to smash through even the mightiest barriers, the strongest of shields, and the most sturdy of armors; within his fists are grasped the concept of 'hard-type' itself.
In contrast, the methods of countering an opponent's action through indirect means, known as the 'soft-type', is about the joining of energies rather than the opposition of energies. Softness is about working together with an existing power rather than openly opposing it through force. Such a method requires finesse and acceptance; coordination with the flow of the opposing power. This principle is referred to as 'aiki'. It is built upon three aspects: understanding of the flow, blending with the flow, and then merging into said flow in order to interfere with it in a manner befitting the master's whims. The way of softness is inherent to Seireitou's Hakuda, to such tremendous effect yet with a subtle grace, like a masterful dancer moving themselves across a dance floor busy with others dancing about. For a run-of-the-mill master, they would view a dancer of their choice, watching closely as they sway and move in the manner of their choosing, most commonly to the song playing, and once they feel comfortable, they would jump in and join in the dance as that individual's partner. This would be a proper analogy to describe the role of aiki within martial arts. But for Seireitou, it is a natural action on his part, so much so that he could shift between partners as he moves through the proverbial dance floor without needing to wait out his chance; such is his experience and mastery. He describes it as a 'waltz of souls', in which the mind and body flow with the opposing power in true harmony before inflicting its interference. Seireitou has demonstrated aiki by walking through an entire battlefield filled with opposing sides locked in ferocious combat without ever being noticed or acknowledged by a single one of them. It was as if he were the natural breeze of the wind flowing along the openings in each and every person's own blind spot, weaving his existence through the battlefield so perfectly that it is hard to believe it was the act of a real person. Of course, this is not true solely of living beings and events, but even of individual powers and abilities. Determining the flow of an opponent's ability or technique is no different a feat, and similarly, Seireitou's mastery over the way of softness makes it possible to overturn the flow of nearly any power he is familiar with; even to the point of using such powers against the ones who are using them. His ability to adapt to the circumstances and blend into the flows around him makes it possible to perform even the most difficult and nigh impossible feats as if they were a natural act.
Connecting and destroying, soft and hard, yin and yang; this waltz of souls conducted through the complimentary yet contrasting natures of the martial arts enables Seireitou to dominate the 'battle paths' (戦道, sendō) between himself and his opponents. Within combat, the battle paths refer to the engagement distance between warriors and how that distance may or may not change over the course of a fight. Discerning these battle pathways enables Seireitou to construct a sort of 'sphere' around his person and his immediate vicinity where he can influence. It is perceived as a large conceptual sphere that surrounds the entire influential space. Hōsen Kuramoto, being a master of Hakuda in his own right, saw no reasonable opening when initially confronting Seireitou, feeling almost frightened at the size of his sphere of influence; as if knowing that all manner of opposition that were to move within its range would be crushed without fail. It is likened to shogi, a game which involves positioning yourself at a point where you are at the greatest advantage, in which the purpose lies in 'occupying an enemy's territory'. This is where the styles of hard and soft coalesce. To elegantly control the flow and then using them to overwhelm the opponent with force, Seireitou performs these two styles with such swiftness and skill that it resembles instantaneous phenomena. Any enemy that enters this space is almost guaranteed to be defeated.
Mastery over Kei: While hard and soft denote the form Hakuda takes, it is 'kei' (勁, "power") that comprises the nature Hakuda will take. Although most martial artists are only familiar with the idea of their strikes smashing into their targets in order to crush them, this is but one of the methods in which a martial art technique's power, or more specifically its 'kei', can take. There are some Hakuda masters who can transmit the force of their punches, so as to harmlessly let their attacks pass through structures in order to cause injury to their true target. Some strikes can seem like they can crush bones, yet when they impact the flesh, the outside remains with nary a scratch yet the insides of the target are rent asunder. 'Kei', in other words, is what determines the nature of a martial art technique and how exactly its power will manifest. As a Hakuda master of unrivaled stature, it goes without saying that 'kei' is a concept very well known to Seireitou, to a point that the way in which he expresses the power of his Hakuda techniques is limited only by his own imagination. Whether it be a force that collides, a force that penetrates, one that reverberates, transmits, neutralizes, or however else, it is an action that is second nature to him. Such masterful expressions of power through technique resemble magic to most onlookers.
Mastery over Reiki: As he who is the authority of Hakuda itself, Seireitou is intimately familiar with the concept of Reiki.
Foundation of Hakuda
- "I already know the outcome if I fight him. I can tell from his punch how hard he has trained. He's only been punching with that single hand, not because he's underestimating me... but because he's thrown that punch for so long so many times that he's perfected it. I already know what awaits me if I were to get hit by his fist."
- —Datara Kawahiru noting the degree to which Seireitou has conditioned himself.
Ikkotsu (一骨, "Single Bone"): When a martial artist becomes a true master, it is not through acquiring the most advanced techniques but by developing the most basic of principles into absolute strength that cannot be overcome. The Hakuda Grandmaster of the Soul Society is not someone that is respected and feared because he possesses a thousand techniques, but simply because he is strong with even the most fundamental of martial art technique. That is what the Ikkotsu is to Seireitou. It is just a punch. Nothing intricate, nothing complex. That's all it is. But that one punch incorporates the millions of years of development that the martial arts have gone through. The teachings of every martial art style, every system of combat, every technique and maneuver — the Ikkotsu is a crystallization of martial arts in their entirety. It is perhaps why the technique itself is known to very few within the Soul Society. Simply put, the Ikkotsu is not something that can be taught, for every Ikkotsu is different for every martial arts master. The punch is a reflection of what they have seen when faced with the summit of martial arts mastery. Even among other Hakuda masters, they train their punches every single day with the aim to one day achieve the perfection of the Ikkotsu technique. As the man that stands above them, Seireitou's Ikkotsu itself is a strike in its own class.
What makes the Ikkotsu the pinnacle of martial art development lies in the most minute of details that are involved with its execution. Every single factor, from the stance adopted by the body, the movement of the legs, the turning of the hips and the shoulders, the extension of the arm, the clenching of the fist, the thrust of the punch itself, and everything in-between; each and every part adopts the sheer magnitudes of martial art theory and combines every significant feature into that single strike. These are all factors that are not always consciously controlled and cannot be so easily fine-tuned. It is a feat acquired through experience and the application of knowledge obtained throughout countless centuries of combat. It cannot be stolen nor mimicked, the level of skill that such a punch demands is simply far too great to copy. Behind Seireitou's fist lies every single opponent he has ever encountered, an embodiment of all his victories, all his defeats, and each lesson he had gleaned from them, which has risen the Hakuda Grandmaster to the apex of the martial arts summit that he now occupies. It can no longer be said that Seireitou uses the Ikkotsu, but more accurately, every punch that Seireitou throws is the Ikkotsu.
Seireitou's punch is the concept of strength itself crystallized into his fist and given form. Therefore, it is not something that is thrown without proper cause. The Ikkotsu is a power that can warp space and time at the peak of its execution, shattering apart the very air around him, which spells instant death for nearly any opponent that dares stand before it. In fact, it would be more accurate to call the Ikkotsu something that crushes anything that stands before it; the strike itself being a force of nature that personifies 'shattering'. As someone that values life, Seireitou must consciously restrain his own might in order to avoid such an outcome. He must instead opt for the use of a jab, a punch in which only the arm is involved rather than the entire body. The difference between a street fighter's punch and a martial artist's punch can also be considered an equivalent relation between a jab and a true punch. Therefore, for Seireitou to jab, it means he is not fighting as a martial artist but as a common brawler. In other words, he is not taking his opponent seriously. When jabbing in the most casual manner possible, his striking power is weakened to even less than a hundredth of its true capability, but the sheer volume of force that it still retains behind it is not to be underestimated. Seireitou's jab 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. With a similar degree of power, a jab from Seireitou dealt to a direct location such as the head or the arm, would cause the entire limb to collapse onto bloody pieces. Even as a jab, his strikes maintain frightening potency. Even from a distance, the Ikkotsu distorts the air by way of pure brute force, causing a wave of air pressure to crash into his target. The air bends and snaps to accommodate this distortion of space, smashing apart the target and victim without prejudice. Because of the nature of his strike's strength, normal spiritual attacks are rendered useless against it, as the distortion of space and the air bending around to fill in the vacuum make it difficult for anything to pass through it unscathed, much less at all. Due to his jab's enormous offensive power and quick speed, it can also double as a seemingly impenetrable defense, able to destroy or disrupt any attack before it hits Seireitou. In addition, because his punch works in this manner, it can even bypass normal defenses.
It is possible for the Ikkotsu to be used in other ways depending upon how the hand is formed. After all, though the basis for Ikkotsu is a punch, it is, in actuality, a strike created by a single hand. It can take any form the martial artist wishes, for they have mastered martial art theory to a point where any teaching can be applied to any technique without difficulty. This would hold very little meaning to mere practitioners, but to Seireitou, the very act of changing the positioning of his fingers or the way he shapes his hand can produce entirely different yet equally viable methods of attacking; for instance, tegatana (手刀 (てがたな), "Hand-Sword") is the act of shaping the martial artist's hand flat so that it resembles a bladed weapon. Whereas a classical Ikkotsu is thrown with the mindset of 'crushing', the tegatana is a strike thrown with the mindset of 'cutting'. By holding his hand in this knifehand gesture, he can swing the Ikkotsu across in the direction of his target and everything in the wake of his hand's arc is slashed apart no differently than if it were done by an actual blade. It is capable of reaching an incredible range, completely slicing apart all things in its path. Similarly, just as it is not limited solely to the act of a standard punch, the Ikkotsu is also not limited only to the hands. It can be conducted by the legs as well. The Ikkotsu is not a technique for Seireitou but the very act of striking itself, for it has become second nature to him. For the Hakuda Grandmaster, it makes no difference if its by his hand or by his leg; even a nukite or a headbutt can be the Ikkotsu. As such, the Ikkotsu can also be performed as a kick, enabling him to unleash tremendous whirlwinds of force.
- "I can't move... It feels like I've been chained down. My body is reacting, it refuses to get near his fist... That fist represents the certainty of death."
- —Ichigo Kurosaki's instincts warning him of the danger behind Seireitou's real punch.
Although the Ikkotsu is a technique encompassing strength and versatility for Seireitou, every case discussed so far has only been in matters where he has consciously held himself back. But the true terror lies in when he decides to throw a serious punch. The 'true strike' is an Ikkotsu in which Seireitou devotes his entire being into every strike he throws, turning it a 'martial artist's punch'. The difference between his jab and his serious punch is so vastly different that it can be compared to night and day. The entirety of his essence is concentrated into that single strike with every move. For normal humans, this simply means utilizing all of their muscles in that single punch, but for a spiritual being like a Shinigami, their reiatsu is also a part of their physical strength and as such, it is also a factor when utilizing this sort of serious strike. When Seireitou throws a serious Ikkotsu, it is not just his physical might but also the vast weight of his spiritual pressure that is behind it. The enormity of his strength and the massive weight of his reiatsu which follows his body is such that a serious strike carries a magnitude that is capable of literally cracking dimensions themselves. Streaks of white reiatsu follow every serious Ikkotsu, delivering such tremendous power that anything within its path is vaporized. It becomes possible for such enormous volumes of pressure to eventually have an effect on the surrounding area, altering air currents and even influencing weather phenomena. When witnessed from afar, the serious Ikkotsu almost resembles a Cero, blasting through everything that stands before Seireitou's fist. Such an act spells unavoidable death for all but the most powerful of adversaries.
Sōkotsu (双骨, "Double Bone")
Mastery of Reiatsu: Among the Zankensoki, it is typically Hakuda masters that make the most use out of their reiatsu as a means of combat. They cultivate and refine their technique through Reiketsu, which translates into a means of deciding how spiritual pressure is utilized and applied. They are able to create a limitless degree of methods in which to utilize their reiatsu, ranging from basic expressions to the most advanced applications. As Hakuda is an art that must come from the heart, the use of spiritual power through the martial arts is limited only by its wielder, and the Grandmaster of Hakuda himself is capable of feats are beyond the imagination of other martial artists. Through years of training and battle experience, coupled with immense levels of self-control and tempering of his spiritual prowess through Hakuda, Seireitou possesses a nearly perfected form of control over his spiritual pressure.
Reiatsu naturally is emitted from the body as the active form of reiryoku. However, the degree at which it is released, as well as the amount, the behavior, and the rate of expansion and contraction, are all factors that can be controlled through Hakuda training. Because reiatsu, much like the body's own movements, can be read and predicted, being unable to efficiently mold and channel it is akin to telegraphing your intentions to the opponent. Keeping reiatsu close to the body and not allowing it to streak behind during actions, for example, allows a martial artist to avoid being detected by an enemy; a feat accomplished through reiatsu control. Being in complete harmony with mind, body, and soul also means that reiatsu no longer functions separately than the physical body but moves naturally together with it. Therefore, for someone like Seireitou, the transition from concentrating to releasing reiatsu is instantaneous, such that when Seireitou flexes his spiritual pressure, he can unleash tremendous degrees of force within the same instant, while it would take even a seasoned master a couple seconds if not moments to build up a similar expenditure. With a stare, Seireitou is able to emit a highly refined discharge of immense spiritual pressure that can almost immediately knock out most warriors who lock eyes with him, possibly even causing some kind of brain damage as a consequence. The most minimal movement can carry a massive discharge of spiritual pressure, leveling entire concrete structures, but can even be unleashed in refined manifestations as well, with a single touch of his finger being enough to send intense waves of vibrational spiritual force coursing through his victims. Because the process is instantaneous, using Reikaku to anticipate Seireitou's actions is an nigh impossible feat. The moment one tries to do so or even considers doing so, the action has already been carried out, making the very act of sensing him to anticipate his move a pointless endeavor.
Seireitou's control over reiatsu is such that he can release and mold his power with minimal effort. His spiritual pressure is a part of his own body, like an additional limb, and can be used as a weapon during combat. Not only can he manipulate the rate and consistency at which it is released, but Seireitou can also determine the form that it takes, whether he releases it in bursts, as overwhelming waves of force to serve as his fists, or even as defensive layers to serve as his shield. His active reiatsu, to those who can actually see it and perceive it, can appear as though it were swirling waves of energy that can be controlled either by his thoughts or by the movements of his hands. As a part of himself, his reiatsu can serve as a means of scouting out the surrounding areas around him, letting him pick up on things that he would normally have missed or been unable to determine otherwise. Seireitou 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. 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. Even if his power is initially released as subtle waves of force, they can instantaneously become crashing waves that demolish everything in their wake. In a similar vein, coursing his spiritual pressure harmlessly through the body of his victim and then allowing it to become a crashing force can allow him to ignore certain targets while only destroying the intended target. Seireitou's mastery of Reiketsu is such that he can even alter the nature of his released spiritual pressure at any moment, not only its behavior. This has allowed him to perform a variety of feats, even enabling him to match the same wavelengths, density, and potency of a Hollow or Arrancar. He has demonstrated this by having his body radiate with an aura akin to a Cero, producing a subtle eerie humming sound, as it simply fades in and out instantaneously as needed. Seireitou could even release bursts of reiatsu, in the same vein as the beams fired by Arrancars and Hollows, which follow the arc of his body's motions much like the Cero utilized by Tier Harribel.
This skill of controlling the nature of reiatsu is centered upon the martial art principle of 'kei' (勁, "power"). Certain kei, such as hakkei, invoke a particular intention of action that determines how the reiatsu will behave and interact. In other words, kei is the concept of how the ki of reiatsu is applied and altered to suit the whims of the wielder. As such, as somebody who has mastered kei, Seireitou can invoke any sort of change onto his reiatsu and how it will interact with his surroundings. For example, the act of luring (yin) is an initial active use of soft-type, intended to pull in forces thrown toward Seireitou, like the waves of the ocean that crash onto the shore, drawing in whatever floats in their waters, and leading them in a path that the latter desires. This can often be either proceeded or followed by the act of accumulation (xu), in which energies and forces are gathered together and layered together in some form. Neutralizing the force (hua), also known as melting or dissolving the offensive, refers to when pure force is directed toward him and subsequently neutralized by causing it to literally melt before him, with conceptual or intangible forces appearing to have liquefied before ever reaching Seireitou's person. It was shown that when another martial artist engaged Seireitou in combat and sent forth rippling displays of distorting force, Seireitou was able to have them melt and neutralized the offensive as they appeared as ripples in space around his body.
Beyond releasing reiatsu and controlling its nature, being able to control its flow is also an aspect of Reiketsu. As many often state, spiritual power flows from the soul outwards, changing from passive reiryoku into active reiatsu. The reiatsu of a Shinigami will continue to ceaselessly flow, for as long as the heart is still beating. If the heart beats, then it is an impossibility for the reiatsu to cease. This is because the ebb and flow of reiatsu is the same as the breath of its wielder. If there is no breath, then there is no life, and as such, as long as there is life, reiatsu will continue to flow. With this understanding in mind, Seireitou's mastery of reiatsu control has allowed him to fully dominate the flow of his own reiatsu, to a point that he can even function in what can only be called a state of death, as he can stop the flow of his spiritual pressure entirely. But he is not limited solely to his own. Mastery over reiatsu as a concept enables him to influence not only his own reiatsu but also the reiatsu of his opponents; no different than manipulating an enemy's joints or striking their pressure points. Through mere touch, he can temporarily halt the flow of their own spiritual power, to the point of causing them to lose consciousness. If he is capable of imposing his control over their reiatsu, Seireitou could choose to permanently stop its flow, in which their heart stops beating until their life fades away. However, this application of reiatsu control becomes more effective when used against free-flowing reiatsu; in other words, reiatsu that has been released from an opponent rather than reiatsu surrounding their bodies. This enables Seireitou to capture his opponent's reiatsu, reshape it, and utilize it as his own weapon. To a true master such as himself, such an act can even be applied to techniques of reishi and reiryoku as well. As a facet of mastering Kiai, the skill of molding spiritual power can be further developed in battle through the higher realms of Hakuda, such as Kiroku.
- Sword of Hanullim (実典の剣 (ハヌリムの剣), Hanurimu no Tsurugi): At one time, Seireitou possessed a Zanpakutō named Hanullim, but after ascending to the realm of a true Hakuda master, he had assimilated the developed power of the Zanpakutō back into his own soul and had become a complete entity. While Seireitou could always create swords and other associated constructs out of reiatsu, through the Reishuken that he himself created — a solid shimmering blade of white spiritual energy that originates from his hand, which is held in a knifehand — he has also demonstrated the use of an enhanced version of this technique which he refers to as the 'blade of Hanullim'. It possesses a far more intricate appearance, appearing as a golden blade of reiatsu that is bathed in a green aura, with ephemeral markings that appear along the upper edge. The blade itself possesses no unique abilities, but its sheer power far exceeds anything produced by the standard technique.
- Instantaneous Expanding and Contracting
- Flow Mimicry: An application of controlling the flow of reiatsu, Seireitou demonstrates his mastery over reiatsu by being able to emulate the flow of other powers, such as another person's reiatsu, their spiritual abilities, and even Kidō. In particular, he can mirror the flow of any Kidō spell or reiatsu technique that he possesses a degree of familiarity with through his own reiatsu. By then reversing the flow of the reproduced reiatsu, altering its direction so that its spin is opposite to that of the power he is opposing, Seireitou can completely neutralize the opponent's own ability by hitting it with his own reiatsu. It can be described best as a maneuver which highly resembles the Hanki principle; in fact, it can be said that what Seireitou utilizes is a more advanced version of that very technique. However, against sorcerers of tremendous might, it may be considered impossible to match their most powerful spells with a technique that relies solely on an individual's reiatsu. Despite this, Seireitou does not necessarily need to neutralize the entirety of their spell, but by combining this principle together with Ikkotsu, and then striking at the vital points of a spell, it can be rent asunder all the same.
- Hoshikudaki (星砕, "Star Destroyer"): Seireitou's own personalized form of the Reihai technique which allows him to bring out the maximum potential of his reiatsu, the Hoshikudaki is an ultimate battle aura that clings to his body with an overwhelming ferocity rivaled only by the unusually calm nature of his spiritual pressure. He refers to it as the pinnacle of both power and control. Rather than being considered a classical technique, the Hoshikudaki is simply the act of Seireitou concentrating his reiatsu to a higher level than his standard base power; something that is reserved for opponents that prompt him to bring out even more power than that which he naturally emits.
Realm of Kiai
Within Hakuda, there are four realms that encompass the teachings of all martial arts. The first realm, Kiai, is the state where all Hakuda practitioners begin their journey, and yet, it is rare for even one in a thousand to ever truly grasp Hakuda at this fundamental level. Mind, body, and soul — the realm of Kiai trains one to bridge together these three aspects of self until there is no distinguishing between them. They are united in every sense of the word. For one to be called a master, they should be able to engage the principles of Kiai as though it were second nature. As the Hakuda Grandmaster, Seireitou is no exception, and demonstrates perfection over this Hakuda realm in how his entire existence operates as a single entity. Uniting his aspects of self is an act that demands no conscious effort, a result of his millennia of Hakuda training and combat, which enables him to produce physical phenomena originating from within the mind as a thought or the soul as a belief through his own body as a martial art.
Aspect of the Body
- Shintai Seiatsu (神体制圧, "God-Body Control")
- Independent Action and Response
- Control over Instinct
- Significance of Stance: All movements, form itself, begin at one's stance, which determines to what extent and nature one will behave. On a physical level, stance is essentially the art of distribution, foot orientation and body positions adopted when attacking, defending, advancing or retreating. Therefore, stance is a configuration of combat behavior. It denotes what foundation the martial art style is built upon. From one's stance, at the root of all martial art, there lies the possibility for all things to bloom forth. The very concept of a stance lies in its purpose of creating a frame; a groundwork from which a martial artist may proceed to act. Adopting an offensive stance or a defensive stance, for instance, can enhance the effectiveness of his reiatsu in matters of attack or defense respectively, allowing him to further fortify his own strikes or even increase his durability when taking on an opponent's own attacks. Such an act has enabled him to weather through abilities of considerable might that would have possibly managed to severely injure him otherwise. On the level of souls, it becomes a conceptual power, as the idea of stance permits one to ground themselves in their own established reality. By anchoring to reality through the stance, illusion-based powers and even reality-warping abilities are rendered useless when inflicted on Seireitou, as he has grounded himself in the unaltered reality. He becomes the immovable mountain that pays no heed to the wind that demands it to topple over, regardless of how fierce it howls. For the Hakuda Grandmaster, the idea of stance is a natural flowing concept that requires no preparation, no need to ready the mind or spirit, for his mastery is at a level where such things are unnecessary; it is a natural response to whatever circumstances may arise.
Aspect of the Mind
- Mukotsu (無骨, "Empty Bone"): Those who master Kiai have ascended beyond the realm of standard hand-to-hand combat; a result born from unifying mind, body, and spirit to act as one. Body and mind act together, and thought becomes action itself. Mukotsu, therefore, is not a mere technique but an expression of martial art teachings. Thought alone becomes Seireitou's 'fist'. Distance is no longer a factor. So long as it is within the grasp of his comprehension, so long as it is something he can perceive as an enemy, whether it possesses a tangible form or not, he can strike at it with his mind. Mukotsu is a strike that is removed from the law of causality, as it eliminates the need for intention to instruct the body to strike, for the intention itself becomes the strike. Yet, it is not a power born from transcendence, but one forged by a martial artist that has surpassed reality through pure skill. In doing so, the warrior no longer becomes a simple fighter, but a weapon of force in its purest sense; a force of destruction taking the form of a single man that can level armies with a glance. The attack can come crushing down and tears apart any and all opposition that should meet Seireitou's perception, annihilating anything that is regarded as a danger by him without prejudice. Although it is a power that can induce physical devastation like the Ikkotsu itself, the Mukotsu is not a fist born of the body but of the mind. It is a conceptual attack being materialized into the world by Seireitou's own will as a martial arts master. Therefore, the scope of what Mukotsu can strike is limitless. So long as it can be perceived as something that can be attacked, it will be smashed apart with overwhelming force. Elements of nature and conceptual forces are no exception. Even illusions can be broken, and Kidō collapses before it. Seireitou has demonstrated the reach and scope of the Mukotsu by shattering a powerful Haien that took on the form of a massive wave of flames, cast by a master sorcerer with whom he had once quarreled. There was no need for him to be concerned, neither for the force of the flames nor the tremendous heat that emanated off from them. Rather than simply striking at it wildly, hoping to blast them away only for the magical fires to reform, Seireitou was able to snuff their existence out through the Mukotsu. It could not only tear apart the wave of flames but the heat itself that posed a danger. The attack was able to reach deep into the heart of the spell and shatter the conceptual core that was holding it together, eradicating its existence before it could ever reach his actual body. It is important to note that because the Mukotsu is not a mere technique but a martial art concept willed into reality, Seireitou can wield the technique not only as a means of direct offense but also as a means of defense. Rather than simply smashing apart any opposition, Mukotsu can instead be used to block or redirect dangers, just as the physical martial arts employ both hard and soft type movements as well. Through this application, Seireitou is able to redirect anything perceived as a danger, such as energy produced by Zanpakutō, Kidō, or even other spiritual techniques such as Cero. The same goes for illusions and hypnosis as well; anything, even intangible existences, can be redirected all the same. In most cases, such a phenomenon is invoked through a mere glance, no different than how the standard Mukotsu is performed. As a teaching of martial arts, Seireitou is able to stack Mukotsu onto other techniques as well, such as enhancing the nature of his physical Ikkotsu technique to strike at conceptual or intangible dangers. Similarly, other teachings can be channeled through Mukotsu as well; one instance of this was shown when Seireitou had managed to shape the Mukotsu into the concept of dragon claws, which made it possible to tear into powerful barriers that were designed to be impervious to physical assault.
- Shukuchi (縮地, Reduced Earth): Upon reaching the pinnacle of Hakuda, the need for footwork becomes negligible. Within the martial arts, the prospect of movement is centered around the maai, which refers to the distance between combatants, and the entirety of movement becomes focused on how best to conquer this engagement space. Of course, in the case of most martial artists, their mind tends to move faster than their body, which allows their intentions to be read and therefore their movements can be anticipated. Maai is a battle of physical and mental distance as well. But when mind, body, and spirit are mastered to the fullest and are embraced in a perfect union, the line between movement of the body and the materialization of intention is nonexistent. Once the intention to cross a distance is invoked, the action occurs instantaneously. Thought becomes movement itself. This is known as the art of reducing earth, the Shukuchi, a technique regarded in legend by the gods who first utilized its ability; as achieved through the skill of a Hakudaka of Seireitou's prowess. It is by no means an act of enhancing speed nor is it mere teleportation, for what it actually happening is the instantaneous shifting of position as though no actual distance was covered. 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 nonexistent as the distance is crossed instantaneously. The technique reveals to possess the ability to even allow Seireitou to escape the space-time techniques utilized by Senzui Kururugi, 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 domination over the engagement distance between fighters imposed by Seireitou's Hakuda rather than accelerated movement.
Aspect of the Soul
- Ryūshin (竜心, "Dragon Heart")
- Uchū no Myaku (宇宙の脈, "Pulse of the Universe")
Realm of Kiroku
At the level of Kiroku, thought becomes phenomenon; concept itself materializes through the body. It is the idea of being able to adopt the idea of Ki from a source either experienced personally or encountered in some indirect form, taking that concept onto oneself and drawing power from it to wield as the martial artist's own strength. Power itself can be cultivated through the adoption of ideas and concepts from other sources. Martial arts, at their core, have always been about learning from every experience, and at the Kiroku level, experiences themselves become pools of wisdom and knowledge from which tangible power can be drawn from. For most Hakuda specialists at this level, Kiroku is expressed as mere acts of mimicry. It is seen in martial art styles that attempt to emulate an animal or a behavior found in nature. However, for Seireitou, his Kiroku is nothing so shallow. What he does is not mimicry but recreation. No matter the concept, that which is adopted by the Hakuda Grandmaster is not a copy but a recreation of the concept that aims to surpass the original principle. In essence, Seireitou transcends the concept itself, turning it into a power all his own. He has managed to develop and refine his Kiroku to the point that the entirety of his mastery over the second realm of Hakuda is embodied by nine distinct techniques that are referred to as the "Shiroyasha's nine tails" (白夜叉の九尾, Shiroyasha no Kyūbi). Of course, to call them mere techniques would be an insult, for they are crystallized embodiments of Kiroku itself as a whole. As the Hakuda Grandmaster, these serve as evidence to Seireitou having redefined Kiroku as something belonging to him rather than a martial art principle he has simply learned how to perform. They can be considered concepts in their own right; expressions of phenomena recreation through the physical body that momentarily tread onto the realm of the inconceivable.

Main article: Hanullim (spirit)
Hanullim (実典 (ハヌリム), Hanurimu; Korean for "Ultimate Reality", Japanese for "Law of Essence"): The manifestation of his Sōzōshin and Kitsune powers, Seireitou once wielded a Zanpakutō that was regarded as the most dangerous and malicious of all Zanpakutō in the history of Soul Society; a fitting companion for the man renowned in legend as the Shiroyasha that struck fear in the hearts of his enemies. Back when he utilized it, Hanullim took the form of two katana, one with a white hilt and the other with a black hilt; both of which had unique symbols etched onto either side of the blades running along the blunt edge. Seireitou and Hanullim have always shared a peculiar relationship. Due to its malicious nature, Hanullim was always a Zanpakutō that tried to obstruct Seireitou in a generally progressive manner as the centuries went by. While he always seemed to work alongside his master, Hanullim never seemed to open up to Seireitou, despite a clear willingness to fight off his enemies together with him and to grant him access to the sword's abilities. But even so, the two had a strained relationship that never seemed to improve. Hanullim's interference and blatant attempts at darkening Seireitou's heart during the most inopportune moments was an issue that needed to be resolved. It was due to this conflict that Seireitou pursued the solitary craft of Hakuda so that he could reduce his use of Hanullim, thus preventing the malevolent Zanpakutō from interfering in his affairs.
After his centuries of training in the Beast Realm, Seireitou came to understand the 'concept of Hanullim'. Much like the relationship between a martial arts teacher and their disciple, Hanullim's role in Seireitou's life was to push him to grow and become stronger by any means necessary; even if it meant burning away everything he was in the process. This twisted relationship between the two was what enabled Seireitou to become the Hakuda Grandmaster he was, and in managing to find his own way rather than depending on Hanullim, he had surpassed the Zanpakutō. Eventually, Seireitou and Hanullim would part ways, and much like the Quincy King and the pieces of his soul he granted onto others, the cultivated and developed part of his soul was absorbed back into Seireitou. Zanpakutō and wielder were now one entity from that point forward. Following their merger, Seireitou requested the sword that once housed the spirit be reforged into a pair of tekkō; a sort of memento that he continues to wear often.
Main article: Seireitou Kawahiru/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, with whom he unknowingly bore a child, 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 Suzaku, 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. Similarly so, with the only daughter he had intentionally conceived, Kaguya, he was under the impression that she had died long ago, which was a part of the animosity Suzaku felt toward his father. He has also conceived an illegitimate daughter that was the result of a drunken exchange between himself and Rangiku Matsumoto.
During 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 the methods of torture he undertook with his captured enemies. Severe physical and mental degrees of torture were par for the course, but particularly so, he was known to violate many of his female victims, with the sadist intent of crushing their spirit to the very core. It is unknown how many Quincy women during the war were violated in this manner, though many survived those incidents as they were thrown back for their fellow Quincy to recover, only for it to later be revealed that some of those victims ended up pregnant from the bouts of torture; very few, if any, actually surviving giving birth due to the extent of the injuries they sustained. Several offspring born of these violent unions include that of Bambietta Basterbine and Meninas McAllon, among many others; although it is unknown if Seireitou ever became aware of each and every one of these bastard children.
Appearances in Other Media
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.
- (To Raian Getsueikirite) "Don't say things you don't really believe. Stand up already. Instead of spending time hoping you'll die beautifully, you might as well keep fighting to see another beautiful tomorrow."
- (To Shunsui Kyōraku) "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!"
- (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."
- "Since you're so willing to use such a killing move... then I shall use my own killing move as well."
- (To Kurama Kawahiru, about Shōyō) "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 Miharu Kurosaki, about Takahashi Ishikawa) "I think I'll go home to take a nap before setting out to kill Takahashi myself. Maybe even have a cup of sake before then. Sounds like a good idea. If someone just so happens to defeat him before then... well, so be it."
- (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) "In the past, only Raian-san was able to handle by attacks and repel them with any success. It's a shame he isn't assisting you all. But that has its benefits as well. Because if it's just me... the collateral damage won't be too severe. Won't have to worry about redrawing any maps."
- (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."
- "I'll never be able to protect anything? Hardly. Even with my hands stained with blood, I can still protect that which I want to protect."
- (Regarding the students of Senjukuha) "You can spread all the rumors you want about me. I'll honestly just shrug it off and be on my way, but pointing your swords at my students is something I will not tolerate. If need be, I'll even overthrow the government you all so closely guard."
- (To the Gotei 13, regarding Raian) "The two of us are no different now than how we were back then. In order to become the sort of Shinigami which we envisioned, we have been fighting ourselves. However, the version of Shinigami that he became, I cannot accept it. Therefore, I have to be the one to stop him, even if it means striking him down. Because the only one capable of understanding how he feels is me. What we hate in this world, what we love... It's the same. You guys aren't qualified to cut him. 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."
- (Referring to Shōyō's teachings) "As we live, we carry our weaknesses with us. Whether that is a character flaw, something to do with our appearance, or perhaps our own surroundings, we all carry a self that cannot be compromised with. Because of that, we suffer. That's just how it is, there's no escaping that. But that isn't the only way in which a person can struggle. You can also suffer by resisting those weaknesses. Instead of simply suffering by their weakness, they can face it head-on and suffer while trying to change it. That's what that man taught me. People... have more freedom than I thought."
- "Try to hit me then, if you're so sure of your skills. Send the next attack right here, right for my heart. Make sure to aim real good this time... because if you miss, I'm crushing your skull in the next instant. Don't forget who you're dealing with. I am the Soul Society's Hakuda Grandmaster... Kawahiru Seireitou."
- (To Kentarō Akiyama) "Martial arts was born out of the very instinct of humanity. A need to defend themselves, to ensure survival. They transcend language and culture, belonging to no one nation but to all of us. They provided a means for people to connect with one another. Martial artists are able to communicate simply by the exchange of fists alone. Despite the innate fragility of mortals, they are capable of standing back up in times of hardship, and strive to fight in order to change themselves. You dare stand before me and trivialize their efforts? You dare to speak, with the sound of such defeat in your voice... while holding the title of martial artist?! You've lost your way. You're... unsightly."
- (Reminiscing about when he first founded the Senjukuha) "Do you know why I started this school? It was because I had nothing. I had lost my wife, my kids, my friends... Everything was gone. And all that was left was me. What I could do; my skills, my abilities, whatever. There was no deep purpose to it, I didn't feel like teaching any grand philosophies or meaningful ways of life, so I taught whatever anybody wanted from me; whether that was to learn a craft that would help them in their daily routine, or if it was ways to torture or kill somebody that had wronged them. Pretty messed up, right? But that was me, somebody that was seriously messed up inside. And that seemed to attract others like me, other messed up people, and somehow... one way or another, we managed to help each other find our way after being lost for so long. I think that's what this school eventually ended up becoming, a place for people who were lost to find their way again."
- (To Minato Kuramoto) "There was a time when I felt the same way you're feeling right now. Once I lost everything and learned how terrifying that could be, I kept living an empty life, with no meaning or name of any kind. But the ones who gave meaning to the empty me once more were the people who'd become a part of me at some point. Some really audacious pests barged their way into my life, and before I knew what was going on, they had given meaning back to this empty vessel. Minato, the thing you have to understand is that in this world, you'll sometimes meet some really meddlesome people who will, even without asking, give you the love you need. And for someone like you or me, who understand the pain of loss and the darkness that comes from that, meeting such a person is a very blissful thing."
- (To Minato) "I was never the hero type. Sure, I had people I wanted to protect, and even now that's true, but what I always desired most was to challenge and surpass my limits. I wanted to see the world that lies beyond all strength. There was nothing noble about any of it. And when I began to pass on what I knew to the next generation, I wanted to see how far they could go as well. That had eventually become the purpose behind this cultivated power of mine. When choosing my students, it didn't matter if they were a hero seeking to defend the world or a villain aiming to destroy it. What was important to me was for my abilities to be carried forward. So long as I could do that, I'd have no regrets. Maybe the next idiot will actually do something noble with it."
- "If we want to create a world nobody has ever seen before, we'll do it ourselves. We don't need to rely on kings or gods. It will be something we create with our own strength."

Behind the Scenes
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 the English dub by Jason Douglas, the english voice actor for God of Destruction Beerus from the anime film Dragon Ball Z: Battle of Gods; Ogata Isshinsai from the anime series, Kenichi: The Mightiest Disciple; and Gildarts Clive from the anime series, Fairy Tail.
While Seireitou is his first name and Kawahiru is his last name, his full name is Seireitou Shōin Kawahiru no Jirō. The name Seireitou is spelled with the kanji 精霊 read as "seirei" meaning "soul" or "spirit" and 冬 read as "tou" meaning "winter". 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".
The image depicting Seireitou in the Jinki Fragments arc was drawn by Zanpakutō-Leader on DeviantArt, formerly known as Cayossj2.
