Silk's class goes on a school trip, and she leave UFO-man behind in her room. On the way past Mount Fuji, a monster appears and puts everyone to sleep. UFO-man arrives and wakes up the girls. Silk fights the monster, but begins to lose when the monster begins tickling her. However, this also increases her power, and she defeats the monster, but not before everyone wakes up and the bus with her classmates drives away before she finishes the fight. As she's walking down the highway after the fight, Makoto stops and picks her up, giving her a ride to where the bus was going.
