Haruto Houjou
The son of a Christian minister and president of Saitō High School's Holy Student Council. He has curly blonde hair. Though he has no spiritual powers aside of seeing ghosts, Haruto is entrusted with the seven badges of the school spirits and summons them as necessary. He hates his job and dealing with ghosts, but his attempts to resign or transfer schools are constantly sabotaged by the Chairman.
Kazumi Ryudo
The son 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.
Mutsuki Asahina
The tomboyish, strongwilled daughter of the proprietors of a Shinto shrine, and a miko (shrine priestess) in her own right. Redhaired, pretty, and rather curvy, she is a master of exorcism. She has an aggressive shotacon tendence, an attraction to young boys, and Nino is often a target of this. She is the strongest of the primary human characters and often acts like more like a leader than Haruto himself. She can use her prayer stick as a weapon, and frequently expels spirits out of Kazumi using her "Asahina Special" exorcism attack.
