Members of the platoon and their human allies witness Mois beating up people and taking their money. In disbelief, they try to find clues to Mois's secret activities, but not even her videogram to her father yields any. Hurt that no one believes her innocent and at the same time embarrassed to tell them of her activities, Mois runs out. In pursuit, they encounter a delinquent Mois getting ready to harm some of Natsumi's classmates. To the rescue, Natsumi fights Mois, until another Mois appears. Through a flashback, Mois reveals that she modelled herself after Asami, a brave girl who had once defended the weak. Now Asami has become a delinquent and they must intervene to bring her back from her lone wolf days. Through Kururu's invention which generates holograms, Fuyuki's script, Mois's acting, and everyone else's assistance, they manage to have her return home.
