Chidaruma
Chidaruma is the enigmatic and omnipotent leader of the Devils. He created almost everybody and everything there is in the world of Dorohedoro but apparently Hole was there even before him. Chidaruma's hobbies include eating, creating wierd things, and pulling pranks on unsuspecting people. He takes great interest in people who go above and beyond the realm of normalcy. He took En under his wing when the magic user survived in hell for years by creating a massive forest of mushrooms and living on them. Chidaruma has been keeping a close eye on Ai and his multiple personalities because of their strange developments in magic and devil based research.
