Younger Brother
Kanaka continues to pretend she's dead in front of Saki's house, but this time, Saki ties her up. As Testing Week begins at Iroha High School, the students are let out early and Kanaka invites Saki and Ayuko over to her house to "study". Since Kanaka's room is not particularly welcoming to guests, the girls spend their time in her brother Sōta Amaya's room, much to his mild irritation. As Sōta is introduced to Ayuko, he asks her if Kanaka is giving her any trouble to which she responds that she is "alot of fun" after a long pause. Sōta eventually settles down to study for his own tests, while the girls continue relaxing, with Kanaka claiming they're just "warming up".

AIURA
The story centers around Amaya, Iwasawa, and Uehara—three "annoying, spirited high school girls with zero motivation"—and their classmates. Their daily life is "what happens when there is nothing happening."
