The first-year students participate in an annual treasure hunt event, with Eruna paired up in a team with Otone, assisted by a Mecha Bimii. As Eruna clears the first set of checkpoints, Otone expresses her disinterest in teaming up with her and runs off. When Eruna injures herself after slipping off a cliff edge while searching for her, Otone takes her to her secret hideout to treat her injuries and have teatime with her . Things soon become hectic when Mecha Bimii transforms into a giant mech and goes on a rampage, but Eruna and Otone manage to use their combined abilities to make it out safely. Afterwards, as Otone agrees to help Eruna form her club-in-progress, Seisa grows concerned after witnessing Otone's Anticomplex ability.
