School Jeanne continues her daily battle against demons by freely switching between four different modes to save those possessed. Among them is Nezurakun, a bullied loner who fails to gain School Jeanne's understanding and instead harbors resentment, becoming manipulated by the demon Bubphas possessing the school principal. As a result, he transforms into the demon Bahumat and attacks School Jeanne. Her powerful Active Mode and the agile Bloomers Mode prove useless against Bahumat's status enhancement ability, leading to her defeat. Even when she activates Blazer Mode and frees the principal from torment, School Jeanne exhausts all her strength in the process. Seizing this opening, Bahumat uses status manipulation to drastically heighten her sensitivity, ultimately driving her toward the worst possible ending. [BAD END]
