He later learns the arranged confession was meant to come from a staff member, while the girl genuinely liked him. Witnesses spread a rumor that he toyed with her feelings, further damaging his already poor reputation.

• Lingmeng: Displays both curiosity and fear. She becomes suspicious of Mana and Shido’s family background, but her fear of the supernatural quickly turns into sarcastic speculation once she confirms Kurumi is alive.

• Kotori: Responds pragmatically by verifying Lingmeng’s account through surveillance footage rather than immediately trusting or dismissing it.

• Kurumi: Returns to school acting completely normal and maintains her usual teasing, confident demeanor. She uses the situation to embarrass Lingmeng rather than explaining how she survived.

• After class, Shido and Lingmeng discuss how unsettling Kurumi’s return is. Shido calls Kotori and reports what happened.
• Kotori tells Shido to date Kurumi that Sunday so he can make her fall for him and seal her Spirit Power. Kurumi accepts his invitation immediately. The danger is heightened because Origami may report Kurumi’s return to the AST, and no one knows whether Kurumi can revive again.

• Shido asks Lingmeng for help. She first jokes that she could split him into three pieces, provoking him to shake her; she stops him with a punch to the stomach.

Significant themes

• Facing fear and responsibility: Shido ultimately chooses to confront the difficult situation rather than avoid it.
• Comedy amid danger: The absurdity of scheduling three dates in rapid succession contrasts with Shido’s belief that the stakes are serious.

Themes
