Fuma is the older brother of Kotori and childhood friend of Kamui. He is very good athlete and popular at school. Fuma is very protective of Kotori and takes her to school everyday on his bike. He is also protective of Kamui and is very hurt when Kamui rejects his friendship. Although Fuma is unaware of it, he is Kamui's Gemini. This means that whichever side Kamui decides to fight for, Fuma will become the "Kamui" for the other side. When Kamui becomes a DoH, Fuma's dark side instantly emerges and he becomes a DoE. Unlike Kamui, Fuma fully awakens as a DoE and has complete control over his powers. The DoE Fuma is very cruel and sadistic. One of his powers is to grant a persons true wish. Usually, this is does NOT turn out to be a good thing.
