キョウ

The Fifth-Ranked School Youkai. He is the guardian of the mirrors that lead to other worlds. He also controls the different personalities that humans show.

He has a nihilistic and wild personality, and is particularly vicious to humans. Apparently this is because of a grudge against humans from when he was still an animal spirit. Even if he tries to falsify how he's feeling with a poker face, his emotions still come out through his trail. This is a source of much dismay to him.
