Diyu

"You seek to understand who I am? I am power incarnate, the Madness to counter the Order. And power shall be yours... all you must do, is rewrite this world's Order."

- Diyu Diyu (lit, Sanskrit for Earth Prison, 阿鼻 Japanese for Underworld, 阿鼻地獄) is a spirit of vast power and great insanity. It's goal is to immerse the spiritual planes, as well as Earth into an eternal age of madness and chaos. Hidden for milennia, it has chosen to stay as such until the order of the Seireitei are at it's weakest.
