Mint is told by her physician that she has a possibly terminal illness: the kigurumi disease. If she does not want to die, she must never wear one ever again. Her comrades, hearing she is in the hospital, bring Mint gifts that they are sure will cheer her up. When the visits fail to raise Mint's sprits, she goes with them on a mission to a planet. To her dismay, the day of their arrival coincides with the centennial kigurumi festival. As the other Angels convince Mint to put on a kigurumi, Mint runs and eventually collapses. She wakes up to find that the Angels have put a kigurumi on. Mint ignores the physician's advice. Afterwards, the same physician tells Forte she has the weapons disease.
