Shiraki, a new psychology teacher at the Seimei School for girls, is announced to succeed as head of the school. He is given the news at the principal's house, who is mourning the death of his wife. The principal invites the psychology teacher to spend the night, but warns that he is keeping his wife's body in the cellar as part of a local custom. That night, a restless Shiraki roams the halls and runs into a pale young girl in a blue nightgown. He is then attacked by a woman with sickly green skin and knocked unconscious. The professor wakes up in bed, assuming the attack to be a nightmare. On a hunch, he goes to the cellar and finds the coffin of the principal's wife. Inside is the woman who attacked him, although dead. Shortly afterwards, reports of a missing girl, last seen wearing a blue nightgown, come in from the teacher's students. One of the students, searching for the missing girl, is assaulted and left with two fang marks on her breast. This prompts the professor to research, learning of local vampire legends.(tohokingdom)
