Everyone on the school bus is a villain. A teacher with G-cup breasts loses their sanity, along with male students and regular passengers, everyone becomes perverted and there's nowhere to escape! 'Yuka,' who was an idol at the academy, becomes the target of carnivorous males after a class change and spends a terrifying third semester. Even screaming for help is futile; the school bus turns into a dumping ground for lust!
