Ep. 7: Mitsuki explores school clubs with Hiyori possessing her, leading to comedic rejections and a dream sequence involving a play.

Ayaka persuades Mitsuki to review school clubs while Hiyori reluctantly agrees to observe without joining. Mitsuki tries out for tennis and soccer, with Hiyori possessing her to impress captains who urge her to join, but Mitsuki declines due to excessive paperwork. Interest shifts to kendo when Yukina appears, yet Hiyori rejects the match because of the men's odor, resulting in Mitsuki being knocked out by Yukina while Yūya checks on her. Mitsuki then joins the theater club, where Neko rehearses a play featuring Yūya choosing between a girlfriend and a step-sister. During the performance, Mitsuki replaces Moa on stage, delivering a line about not pursuing someone who is not a little sister. Moa trips, exposing her backside, and Mitsuki wakes from the dream only to receive a text from Ayaka that leaves her shocked.
