Recently, rumours of a woman's ghost on school grounds cause some elementary school students to test their courage. Eko Miyazaki, a middle school student, sneaks into school at night and lies in wait for them. Just as planned, she scares the kids away.

Just then, the security guard approaches, and Eko attempts to escape. However, her skirt gets caught on the fence, and she cannot move. In this desperate situation, a young boy with a cat appears before Eko.
