Mako, Miko, and Mutsuko are three young girls visiting St. Claire Elementary, a school filled with strange legends. They have an abrupt encounter with Kunstrijk, 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, Kunstrijk 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.

The cyborgs are no longer on duty, they live normal lives until a mysterious space ship lands on earth. The only survivor on the ship warns about an evil conqueror called Zoa that wants to conquer the universe, which means the cyborgs are back in action...
