"Gakuen no Ikenie" is a hentai OVA based on an adult visual novel by Erectlip, featuring intense themes of cult coercion and explicit punishment. A busty delinquent girl named Mali faces kidnapping by a priest who demands she abandon her friends to join his religious cult, leading to brutal "divine" violations like nipple play when she resists. Her loyal friend Shoko attempts a rescue but suffers her own humiliating anal ordeal, turning the pair into playthings in a dark academy ritual.
