Hakushin

"Hyahaaaa! This pain is unbearable! Let's hurt each other more!"

A foreign demon who came to Earth with his older brother, Jinzan. Like his brother, he gains power by killing other demons. In order to enjoy the physical pain inflicted by others, he always seeks someone strong.

Although he usually acts according to his instincts, he always is loyal to Jinzan's orders. Even though he knows he's being used like a tool, he doesn't seem to want to go against it.
