Hotaru and Renge are invited to the Koshigaya’s house for breakfast. Afterwards, the girls, accompanied by Kazuha, go to the beach, where Komari’s height leads her to be mistaken for a lost child. On their way home, the girls stop at a railside noodle restaurant, where a prank by Natsumi on Komari backfires due to Renge’s innocence. They manage to catch the last train home on time, but accidentally leave Kazuha behind.

With Kazuha absent at the start of the new semester, the girls try and find ways to pass the time in class. Later, Hotaru and Renge try and catch a rabbit that had escaped from its pen, only for it to lock them inside the pen themselves, though they are eventually rescued by Kazuha. Afterwards, Renge visits the candy store run by Kaede Kagayama, who finds her to be a handful.
