Oreki navigated Kushida’s past, Housen’s expulsion, and shifting alliances among the classes while growing closer to Sakayanagi and Karuizawa. The arc ended as the school announced a twenty-day uninhabited-island exam, with students beginning to form teams and Ishizaki seeking Oreki’s help.

- Oreki warned Sakayanagi that Amasawa was likely a White Room student targeting Kushida and Ayanokouji, while the school announced a cross-grade exam and Ayanokouji faced an attack organized by Housen and Nanase.
- Ayanokouji turned Housen’s knife attack against him, and Housen was expelled after Ryuuen exposed his assaults and Kōenji confronted him at the Student Council.
- Oreki accepted Class 1-C’s alliance after Utsunomiya offered twenty million Points, and Kōenji joined Class 2-A after helping the first-years improve their exam results.
- Oreki and Sakayanagi followed Kushida’s date itinerary, shared a series of dreamlike encounters, and continued their relationship as their classmates watched them act close at school.
- Oreki signed an agreement for Class 1-C to repay him twenty million Points, arranged an installment payment, and told Kushida he would confront Amasawa before she caused more trouble.
- Karuizawa visited Oreki’s room, where Amasawa interrupted them and revealed that she had recorded a conversation about Tsukishiro’s offer to first-years to expel Ayanokouji.
- Teacher Majima and Chabashira announced a twenty-day island survival exam with team rewards and expulsion risks, and Ishizaki asked Oreki for help after the rules prompted students to form teams.
