A beautiful transfer student, Tatejima Hitode, clad in a jet-black sailor suit, arrives in a classroom where one after another, the dead are beheaded by a flying ski, steel doors in the subway, and a crashing traffic light. The only way to save the cursed high school students is to sacrifice one of them. “I told you, didn't I? Is the enigmatic girl friend or foe?” Envy and fear, love and hatred are all mixed up in this horror story of school suspense.
