Johannes Kleeman

Johannes Kleeman is a devil/human hybrid who was raised at the same facility as Yuuki Anzai, although not a part of the same group. He is a rather carefree and blunt person, and not even blood bothers him. By drinking a little blood every morning and evening he can almost completely control his bloodlust. And because of this, his left eye is almost always transformed.

He is a part of the White Group 07 of the 15th Hybrid Birth Project at ONLO. These devils are called "Children of the Dark" by some. It seems that his departure from ONLO wasn't authorized.
