Ep. 12: Yūya undergoes hypnosis revealing feelings while Hiyori returns to guide Mitsuki through a golden gate
Neko places Yūya under hypnosis, causing him to confess Mitsuki is cute and grope Yukina, who slaps him. After Neko explains the effect, Yūya develops a fever. Yukina visits, noting she knew about Hiyori, while Mitsuki rejects Hiyori’s advances due to his illness. Yūya later bursts into Mitsuki’s room, criticizing her underwear, which leads to her embarrassment. Hiyori then appears, leading Mitsuki through a golden gate to a floating island marked "2F." Hiyori disappears, wishing to be reborn as their child, and returns Mitsuki’s belt. The next day, Mitsuki calls Yūya "Oniichan." Hiyori reappears, placing the belt back on Mitsuki and explaining it is now 30% more sensitive, causing Mitsuki to cry out in embarrassment as the episode concludes.
