Mako, Miko, and Mutsuko are three young girls visiting St. Claire Elementary, a school filled with strange legends. They have an abrupt encounter with Kunstlijk, a human body anatomy model, and Goth, a skeleton model. Both haunt the soon-to-be-demolished science room. Seeking revenge for being vandalized by the three girls, Kunstlijk invites them to the school's midnight party in order to scare them. Together, the five go on a quest to collect three mythical medals that can grant a wish and hopefully save the science room.
