As AntiSkill become curious over how the security bots functioned without any batteries, Mii treats Mikoto and the others by taking them to the public baths, where Mikoto lets Febri have one of her rare Gekota finger puppets. Whilst heading home, the girls are led on a detour to a warehouse, where they are attacked by a mech. As Mikoto fights against the mech, which seems resiliant to her electricity, the mech suddenly stops functioning when it comes close to attacking Febri, allowing Mitsuko to defeat it with her Aero Hand ability. After Mikoto discovers the mech to be curiously unmanned, Febri comes down with a fever and is admitted into hospital. Meanwhile, it is shown that Shinobu is working with the group targeting Febri. Back at the hospital, Mitsuko informs the others about how she, Wannai, and Atsuki came to learn that the man from before was attempting to 'reclaim' Febri. The next morning as Febri seems to make a full recovery, Heaven Canceler informs Mikoto in private that Febri is in fact an artificial human.
