Kakyō

was a Shinigami and a close friend of Kaname Tōsen until her murder, which was the catalyst that proceeded to turn Tōsen against Soul Society.

Appearance
Kakyō was a slim woman with long black hair. Despite being blind, Kaname Tōsen considered her to be "beautiful".

Personality
Kakyō was described by Kaname Tōsen as a person who "followed the path with the least bloodshed", a philosophy that Tōsen proceeded to adopt himself. Kakyō dream was to become a Shinigami, which she succeeded at, and to use her powers to maintain a peaceful world.

History
At some point, Kakyō and her close friend, Kaname Tōsen, sat together as as she told the blind Tōsen that the stars are out, stating that she loves the night sky because it reminds her of the world, with tiny points of light scattered among the darkness that the clouds try to cover up. While Kakyō asserted that she wants to clear away those clouds so that not a single light is hidden and that she will do so, Tōsen merely responded that this is good as he notes that her voice saying his name over and over comforted him even though he could never bring himself to tell her that he liked the clouds. Some time later, Kakyō informed a surprised Tōsen that she is getting married to a Shinigami and will become a Shinigami as well now that she has received her acceptance letter from the Shin'ō Academy. With Kakyō detailing how she will bring peace by fighting Hollows and revealing that he was the first person whom she wanted to tell, Tōsen congratulated her and inquired if there is anything he can do to help, only for a smiling Kakyō to request that he simply stay the way he is while she comes back now and then to tell him her stories.

Soon after Kakyō was killed by her husband because she scolded him for killing a comrade over a petty argument. However, Central 46 refused to punish the culprit, much to the fury of Tōsen.

Soul Society arc
During his battle against Kenpachi Zaraki, Kaname Tōsen recalls the last moments he shared with Kakyō and the promise he made to her grave to uphold "justice".
