Yin

"There are two doors. The door to your right leads to the Soul Society, and the continuation of your existence. The door to your left leads back to the World of the Living, where the man named Seireitou is... and to the end of your life. As you adequately put, the problem is choice. But we already know what you are going to do, don't we? Already, I can see the chain reaction. The chemical precursors that signal the onset of an emotion, designed specifically to overwhelm logic and reason. An emotion that is already blinding you to the simple and obvious truth. That man is going to die and there is nothing you can do to stop it."

- Taikyōkū speaking with Raian Getsueikirite.

The Taikyōkū (嘯風, Taikyoukuu; literally "supreme ultimate"), unknown if he possesses a real name or not, is the self-claimed creator and absolute ruler of the Dangai Precipice World. He credits himself with the creation of the Kōtotsu and Kōryū currents, calling them "detachments from his own existence."

Behind the Scenes
Taikyōkū is based mainly on the Architect from The Matrix trilogy.
