It's the first day of school for Kanako. After a troublesome morning with her roommate Mariya, she goes to the class without having any breakfast. Afterwards a welcome speech is held by Mariya and the school student council.

Yuzuru notices that Kiri and Sachi are getting along very well. Because of that, she gets jealous and thinks that Sachi could become better friends with Kiri than she is with her. She starts to act strange towards Sachi and Kiri. It turns out that Sachi was helping Kiri to pick a birthday present for her. Afterwards, all of them (together with Kanako, Masturika and Mariya) celebrate Yuzuru's birthday.

A new character is introduced—Father Kanae. He seems to have a crush on Mariya (not knowing that Mariya's a boy) and Matsurika, although he is twenty-seven and a teacher there. Mariya later lies that Kanako's "elder brother" died of the "Tchaikovsky syndrome" in B-minor. He asks him to help Kanako because Kanae reminds Kanako of her brother. In actuality, Kanako hasn't got a brother. So Father Kanae tries his best to help her. Unfortunately Kanako is allergic to males and he inadvertently (and unknowingly) causes her great suffering. He later falls in love with Ayari as well.

It is raining and everyone is having some tea at Mariya and Kanako's room. To pass the time, everyone takes out their card games.

It is Kanako's trial, and she is defended by Matsurika while Mariya is the prosecutor and God is the judge. Most of the characters come to testify.

We meet Tota, a 10-year-old boy who is in love with Ryuken and acts as her fiancé. Kanako doesn't want to lose Ryuken, so she starts a beetle competition with him.

It's August 31st, Kanako's birthday. Her classmates, Ryuken and the seniors, Shizu and father Kanae plan to make different parties for her, but at her birthday, she doesn't find anyone. Trying to run away from the expanding seaweed, she ends up at the church, where everyone has made a party for her.
