Mutsu Kokonose
Pure evil in a tiny package. Kokonose delights in irritating people, especially Kashii. He's actually the heir to a powerful exorcist clan and is on a secret mission to Tougen Island.

Kashii Mamoru
This 20-year-old finds himself Kokonose's roommate and unwilling partner in crime. Despite his rebellious looks, he's insecure and totally uncool.

Yamato Kouichirou
Kou-sensei is in charge of Kokonose and Kashii's class. He has the role of the legendard "Dog" in the Momotarou story, and tends to act like an overgrown but lovable puppy.

Chairman Tougen Nagato
The leader of Tougen island has an unpredicatable temperment. He and Kouichirou share a close friendship and a strange physical bond. No, not that way. Actually, it probably is that way. He claims to be "Momotarou."

Hattori Maya
This sweet-but-terrifying teacher of Class 2 has a big soft spot for Kokonose and likes to view everything in a positive light. She's very motherly towards students.

Keith Langley
Langley is the resident doctor on staff at the Academy, and has a gruff personality suited to his ex-military status. However, he seems genuinely fond of the students.

Kimikawa Yuino
Yuino-chan is a stuck-up rich girl, but is very popular with all the boys. She's sometimes sweet and often manipulative. Kashii has a crush on her.

Yura
Yuino's more down-to-earth roommate, notable for her large chest and boyish tastes. She sees a much nicer side of Yuino and Kashii.

Tougen Nachi
Nachi is the Chairman's daughter and is remarkably intelligent and responsible for her age. She takes care of her injured grandfather, Musashi, and has a pet rabbit.
