Yuudai Chiba glimpses Hitoha’s erotic book and desires to view more, while his friend Shinya Satou mistakenly assumes she wants to show her underwear. Hitoha later meets occult enthusiast Sakiko Matsuoka, who believes she can see ghosts. The two sneak into a pool before opening hours; Sakiko thinks Hitoha is performing an exorcism, but she is actually drowning. The next day, the triplets realize they forgot their underwear and assume theft. Their father, Soujirou, arrives at school with the missing items. Embarrassed, Mitsuba implies Soujirou stole them, resulting in his arrest.
