The Angels board a derelict spaceship to look for the lost technology. The spaceship is apparently haunted as ghosts appear from nowhere and chase them around. They suddenly appear in another room where they are served with any desserts they want. Milfeulle, who stayed back at the Angel Base to exercise in the gym, is informed by the Commander that her probation is over and she is finally an official member of the Angel Brigade. Celebrations are cut short when they receive a help call from the other Angels. Milfeulle rushes to the spaceship and goes inside. As she too is chased by ghosts, they end up in front of a large screen with many numbers. As Mint tries to solve the mystery, Milfeulle blurts out that one row of numbers represent her current and ideal weight. Learning that the spaceship is a fitness machine, they must exercise with the ghosts to be free.
