When he takes his seat in class for the first day of school, Koichi is unsettled by his fearful classmates. Despite this atmosphere and warnings from fellow students, Koichi is drawn to the beautiful, distant Mei Misaki, another classmate. But the closer he tries to get to her, the more mysterious she and their class become.
When a fellow student dies a disturbing death - the first of a long chain of deaths - Koichi seeks to learn the truth behind the curse of Class 3-3. But can he get answers before the curse kills him?
