Mafuyu Kurosaki

Birthday: December 21

Former Bancho and co-founder of the Disciplinary Club, she dreams of living a fairy-tale like life of romance and a stereotypical happy school life. Will her instinctive ability to acquire the loyalty of delinquents and her irrepressible need to help people in trouble destroy her dreams? or will she find the love she's looking for in unexpected places?

Natsuo is the name Mafuyu uses in disguise. After defeating the high school's current banchou, Kyoutaro, Natsuo takes his position. Natsuo, like Usa-Chan Man, is an unseen member of the Displinary Club, who only takes action when there's an emergency.
