A New School Year
Hibiki and Kanade are walking to school together when they saw a poster with Umino Minami, a retired ocean saver, on it. They thought that Minami will return to her project of taking care the sea but heard some girls saying that it is an old poster and cannot be that young. Otokuchi and Gakki pulled them to school, afraid that they would be late.

As they entered in the door, they saw Momoko giving them a detention slip for being late in the first day. Momoko, going off topic, says that she and the older Student Council cannot find the new student. Gakki then thinks that "she" might get lost until Momoko spanks and corrects him that the new student is a "he". The five then started to walk into their same old classroom.
