Kagayaki

"The final stage of a martial artist is when body, mind, and spirit become united; this is known as the Kagayaki. When this occurs the body transcends the limitations of known reality. The famous, or infamous depending what whim itched his mind each morning, Sun Wu Kong of reached this point nearly four hundred years ago, where he could pluck a hair from his body and it would arise into a copy of himself, not a mere illusion, but of his own flesh and blood, as real and true as he. He could stride the clouds and change his shape into all manner of things, according to legend."

Kagayaki (輝き, "radiance") is the final evolution of power a human can achieve once they reach the pinnacle of their mind, bodies and spiritual limitations.

Overview
Kagayaki differ from Arrancar, Shinigami and all other spiritual beings in that they are born from Humans. The first inclining of a Kagayaki are humans who possess spiritual powers such as the Quincy or those with radically different abilities such as Inoue Orihime. However to attain Kagayaki requires an immense amount of effort said only to be achieved by a scion once every hundred generations.

The exact method to becoming a Kagayaki is riddled with myths, and some say that only be attaining enlightenment can be it achieved. It is said however that doing so requires a long, and dangerous journey, and even then, many still have not reached this state.

Powers & Abilities
Kyoumei (共振, "resonance"): One of the principle abilities of the Kagayaki is "resonance" a power which allows them to sychronize their spiritual wavelength with those around them. This is the basis for many of their abilities used in different capacities. Only a Kagayaki can possess this power due to the trinity requirement; As such spiritual beings are unable to learn this technique, although some have tapped into its one aspect, such as Shihoin Yoruichi and her ability to assume the form of a cat.
 * Body: the ability to synchronize with the physical impression of the entity or object within the human world.
 * Mind: the ability to synchronize a mental self-image or projection of the entity or target in ones inner mind
 * Soul: the ability to synchronize with the spiritual wavelength of the entity or object in the spiritual realm.

Henshin (変身, "transformation"): Refers to the ability that Kagayaki possess which allows them to shift their form. The limitations of this ability are currently unknown, although Kagayaki prefer to either animal forms or objects. Majeh describes the use of Henshin as reconstructing the self-image. By doing so he is able to assume the form he envisions himself to be in his inner world. Although he comments that extensive, repeated use of this ability is dangerous, as doing so can cause one to "lose sight of who they are" and becoming trapped in the form they assume, in both mind and body. The nature of this power is not limited to the Kagayaki as a whole, it also can affect any part of their body, such as a hair. By plucking a hair they can transform it into whatever they want, be it other beings, animals, or objects. Shukuchi (縮地, "reduced earth"): This ability refers to the teleportation that Kagayaki are reputed to possess. In reality it is nothing more than an highly advanced form of Shunpo taken to the highest levels possible. Shukuchi operates in a series of steps that happen so fast its almost simultaneously. The Kagayaki must first designate the location they wish to move to, which is determined by whether or not reishi is within the area. This requirement is generally bypassed, as the Kagayaki locks on to the emission of their own reiryoku. The next step is that the Kagayaki briefly enters an incorporeal state, in which their body is converted directly into reishi in its purest form. By using a single step, they shift their mass onto the location they previously locked onto. Afterwhich the body is transformed back into its original state. Use of Shukuchi is accompanied by a resounding, "boom" as air is forcibly repulsed when the Kagayaki reappears. Their ability to "lock" onto a location also applies to any place or area they have previously been as well, attributing this power "teleportation".
 * High-Speed Regeneration: This power is a byproduct of Henshin. Because of their ability to literally assume any form they choose, they can simply reform damaged body parts and heal wounds instantly. Unlike Hollows with this power, the Kagayaki can also reform internal organs if need be. Assuming the Kagayaki's form even possesses organs at the time...

Kamui (神威, "gods majesty"): This refers to the Kagayaki's ability to move to and from dimensions. Its function is exactly like that to the Arrancar's Garganta, tearing open the dimensional fabric separating the worlds, revealing a tunnel of whirling, torrential energy that must be focused and solidified to create a discernible pathway.

Enhanced Spiritual Power: Kagayaki possess vast amounts of spiritual power, almost all Kagayaki having at least an Immense Spiritual Power. As a side effect of their transcendence, all Kagayaki become immortal, having an unlimited lifespan until killed. Due to their "resonsance" ability most Kagayaki are rendered immune to the effects of Reiatsu, and at their level, the quantity of spiritual energy simple becomes meaningless. Although most if not all Kagayaki are said to possess rather calm and soothing spiritual energy, regardless of their moral compass.

Tenshou (転生, "heavenly transformation"): Kagayaki do not possess Zanpakutou nor can they, for their existence is of a merged mind, body and soul; one unit, one entity. They do however retain any abilities they had prior to the transformation but if they had a Zanpakutou it is forever gone. But Kagayaki possess a release form they can assume, which is more akin to the Quincy Final Form. Tenshou is the temporary synchronization with the spirits of all things, and it is the true form of Kagayaki, the truest form that they hold as part of their self-image. For some the transformation only has minor physical changes, perhaps becoming a younger, brighter version of their self, others possess forms so alien and strange that they cannot be classified. But regardless of the form the transformation always augments all of the Kagayaki's abilities, and allowing them to use "Chikara" a special ability that all Kagayaki possess. The Kagayaki that have existed generally refrained from extended use of their Tenshou form, because of the damage it can inflict on their environment from prolonged exsposure. The world around them begins to reconstruct itself to the perceptions the Kagayaki has of the world. This can in turn lead to rather strange effects or formations such as the laws of physics unraveling in an area. Many in the human world refer to such areas as magical places where the border between reality and imagination dissolves. Of course this side effect when combined with Kamui allows them to create their own demi-planes where they are God. Some suspect powerful entities such as the Soul King to be a Kagayaki. Enhanced Spiritual Awareness: Kagayaki possess such fine tuned Spiritual Awareness, that they are able to see and hear at nearly any distance in a fashion similar to Clairvoyance. This power functions in the same manner as the Arrancar's Pesquisa - Sonar. However their senses are highly refined allowing them to detect size, shape, form and quantity of spiritual energy. This ability however does not extend towards other dimensional planes, so they are only able to precieve events happening on the same plane of existance. This spiritual awareness is refined enough that they are able to perform rudimentary forms of mind-reading, although this ability is unrefined, it does mean that it is nearly impossible to lie to them. They can instantly and accurately determine the strength and ability of any being with a glance.
 * Chikara (電源, "power"): Each Kagayaki' possess one trait, power or ability. In rare occurances it can manifest in rudimentary forms such as Orihime's ability "The Rejection of Events". All Kagayaki possess some unique power, an ability of such scope, that Kagayaki are often labled as "Gods" by other beings.

Immense Strength: Kagayaki due to their previous martial training, have obtained a level of physical strength far exceeding that of normal even spiritual beings, capable of destroying whole mountains with a single strike.

Immense Durability: Kagayaki possess such high levels of durability that they can simply shrug off otherwise fatal wounds, and continue fighting at full strength. This power works by what Kagayaki call "resonance", an ability in which they instantly and temporarly synchronize with the same wavelength as the origin and attack thereby nullifying or disrupting its effects. This ability however isnt perfect, there is always a measure of imperfection, but it greatly reduces the effectiveness of any attack directed at them.

Behind the Scenes

 * Kagayaki is inspired by the chinese concepts of the Sennin or "immortal person". Most of its abilities were inspired by Sun Wukong (Son Goku in japanese), and his abilities displayed in the tale Jounery to the West.
 * Kagayaki was meant to be an evolution attainable by Quincy and Humans given the variety of forms and transformations, Shinigami and Arrancar have.
