The student council president, Ayano Sugiura, shows her annoyance at always placing behind Kyōko in tests, while her assistant Chitose Ikeda fantasizes about the yuri potential between the two. Meanwhile, two classmates, Himawari Furutani and Sakurako Ōmuro, are at war with each other as they are both vying for vice-president position. Ayano later gets a cold so the others pay her a visit.

A visit by a first year student inspires Kyōko to draw a doujin about her and Yui, prompting Chinatsu to respond with her own story, presented in a fearsome art style. They then decide to make some clay art figures. Later, everyone meets Yui's relative's child, Mari, with Chinatsu reluctantly dressing up as her favorite anime character for her.

The girls try to find way to distract themselves from the Summer heat. While visiting the student council room for some cooling comfort, they meet the silent student council president, Rise Matsumoto, who they mistake for a spirit. Meanwhile, the science teacher, Nana Nishigaki, decides to do her experiments in the student council room.

Yui has a tough time getting Kyōko to concentrate on her homework. Later, the gang try and come up with nicknames for each other. Meanwhile, Sakurako attempts to catch a snake that is loose in the Student Council room. Later, the girls discuss how to prevent getting a cold, though Kyōko ends up getting a cold regardless.

As Kyōko realizes she needs to buy new batteries for her air conditioner, she gets distracted and ends up visiting everyone's homes, only to end up buying the wrong batteries after all. As she decides to have everyone go to the pool instead, Akari misses her train and tries to pass the time til the next one comes. Later, Kyōko visits Yui while she has a cold while Sakurako and Himawari follow Akari around.
