Usa-chan Man
Mafuyu Kurosaki's first alternate identity created to help Hayasaka in a fight. Usa-chan Man is one of the secret members of the Public Morals Club, along with Natsuo (also Mafuyu). Her costume consists of a pink porcelain bunny mask and the Midorigaoka school uniform. Besides Takaomi, Aki Shibuya is the only other person who knows Usa-chan Man's identity. Hayasaka admires Usa-chan Man's strength and heroics. Mafuyu can't tell if Hayasaka is in love with Usa-chan Man or just greatly admires her.
