Corpse Party

The story begins with Ayumi Shinozaki telling a scary story to her friends when they stay after school to clean up after the cultural festival. For Satoshi Mochida, the sound of someone knocking on the door is terrifying, but he’s compelled by the others to open it anyway. To his surprise and relief, it’s just his little sister, Yuka, who came looking for him. Following introductions of each character, the classmates try to tidy up the room, but they’re interrupted by a strange sound. Frightened, they try to leave, but a sudden earthquake catapults them into an abandoned schoolhouse.
