Ep. 10: Mitsuki seeks peace but faces confusion over chastity belt changes and Yūya's unexpected kindness.

10

Mitsuki asks Hiyori to modify her chastity belt, but Hiyori refuses, leading to an argument where Mitsuki’s comments about Hiyori’s lack of effort cause her to leave. Mitsuki initially enjoys her solitude but feels guilty by dinner. Yūya’s kindness makes her blush, confusing her as Hiyori is absent. When Mitsuki rests her head on the table, Yūya performs the Heimlich Maneuver, accidentally causing her to orgasm. Embarrassed, she slaps him. In the bathroom, Mitsuki wonders about her feelings for Yūya but denies love. She discovers the chastity belt is missing and panics, fearing Hiyori has crossed over. Yūya helps her search, and they find Hiyori at the location where Mitsuki first collapsed. Hiyori reveals she made a new, more revealing belt design as Mitsuki wished, and it never truly disappeared. Mitsuki reconciles with Hiyori but is mortified by the new design. Meanwhile, Yūya searches a convenience store for a girl with a big ribbon and wings.
