Terrifying Girls' High School: Animal Classmates(1973)

We find Reiko Ike once again cast as a tough schoolgirl who has to band together with her enemies to upset the reign of their private Catholic high school administration where institutionalized sexual abuse is endemic. The tables are turned on the principal and sanctimonious teachers as well as an American priest when the adult evildoers are publicly humiliated and exposed before the entire student body.
