Toshiya Misumi

At first Toshi is a mentally fragile weak little boy who cant stand up for himself. He cries for everything and nothing. After he meets Mon who shows him without mercy how a man could be if he fights for everything he wants Toshi starts to metamorphose into a much more evil human than Mon. Toshi loses his mind against the thing he turns into and is unable to be any longer a running member of society. He becomes a devil with a fanatical thirst for destruction.
