Kimito's attempt to pull a prank on the naïve Aika results in a new fad spreading throughout the entire school which, due to the students being cut off from popular culture, could last for up to ten years. Kimito has an accidental encounter with Miyuki's panties. Reiko later overhears Kimito on the phone to one of his friends and deduces that Kimito misses being able to socialize with other men and may try to leave Seikan. To remedy this the girls decide to act more manly so he won't leave. Kimito assures them he never planned to leave, he just misses his old friends.
