Makoto is left in shock after her father suddenly tells her that they will be welcoming a new family member. And it turns out to be a boy from another shrine who's the same age. At school, she hears talk about a new transfer student. At the shrine, Gintaro is napping when he notices a boy in a high school uniform looking at him.

Haru, the herald from Satoru's family shrine, wants to be with Satoru and refuses to go home. After an argument, Haru runs away from the Saeki shrine. Makoto asks Gintaro to divine Haru's location, but Gintaro tells her not to interfere.

One afternoon, while Makoto and Satoru are at school and Tatsuo happens to be out, Aki and Sachina visit the Saeki shrine. They are joined by Yuuya and two other boys. Eventually, they begin splashing each other with water by using the shrine dippers, until one is accidentally broken. An enraged Haru gives chase as the children flee the scene, but she quickly gets lost.

As the summer cleansing ceremony approaches, Tatsuo tells Satoru to invite some friends, which leaves him flustered. He continues to practice hard as a member of the kendo club, but he hasn't managed to break the ice with the other members. One day, he gets in a fight with Kosugi, another member, and ends up in a kendo match against Kinugawa, the captain.

Makoto continues to worry about what she should do in the future. Tatsuo tells her to do what she wants, but Makoto doesn't know what she wants to do and turns to Gintaro. And on the day before the summer cleansing, Tatsuo's friend Takami Yoshitomo and many other people gather inside Saeki Shrine to prepare.
