Misa (Kimika Yoshino) is a high school student and good witch who travels from school to school to fight evil (kind of a Japanese Buffy). Her math teacher Miss Shirai (Mio Takaki) is having an affair with a female student, providing a few erotic scenes throughout.

When the students stay after school to retake a math test, they are murdered one by one as sacrifices in order to make way for Lucifer to enter the world. Does Misa have enough power to stop the bloodshed? Will she save the day? You'll have to watch to find out. Nice twist ending. Plenty of blood content.
