The son (grandson in the manga) of a Buddhist monk. His body is seen as ideal for ghosts and he is constantly possessed by the ghosts of people, animals, and demons; his friend and fellow Council member Mutsuki has to exorcise him several times a day. He is incredibly amorous of females, particularly the Toilet Hanako of the school and all the other Toilet Hanakos. In the manga, this obsession is a family trait shared by his grandfather Taro Ryudo, owner of the shrine where Kazumi lives.
