After they return from the mountains Kyohei, Hibino, and Utao go the beach, but a typhoon interrupts their agenda. To make matters worse, the inn experiences a power outage, not to mention numerous leaks from the ceiling. Kyohei and Hibino attempt to make repairs and Utao uses Kukuri to assist them. On returning to the city, Hibino goes to return books to the library, and, because she forgot one of them, Utao goes out to catch up to her. Hibino encounters Aki at the library, and he questions her relationship with Kyohei. Utao finds Hibino and challenges Aki to a duel at the park with their kakashi. When Utao tells Aki that kakashi are meant to save rather than destroy, Aki cuts the match short and departs. As the girls return home very upset, Kyohei tells a worried Utao that kakashi actually have human hearts.
