Noa encounters Miiko and invites her to an amusement park, where she revels in Miiko's cute behavior before inviting her to her house. She visits Arisugawa Academy, where she is pranked multiple times by Kurumi but enjoys her reactions and also takes her home. The same offer is extended to Haruna, who accepts as she assumes Miiko and Kurumi are causing trouble, and Miyu, who agrees after receiving a straightforward request without reason.
