Kusozako Fuuki Iinchou Kaeri-chan

The former all-girls Yurigawara High School is going co-ed this year. The new student, Mizuhaya Saotome, meets Kaeri Uchihishi, the head of the school discipline committee, who talks loud and acts tough, but that just makes her seem blustery and kind of a jerk! A comedy about school morality begins!
