The gang all decide to head to the local fireworks festival. Saya suggests to Kokonotsu that he should invite Hotaru, just as he finds Hotaru at the shop trying to pick a "Homerun Bar" ice cream with a winning stick. Kokonotsu asks Hotaru if she wants to go to the festival which leads her to wonder if it's just the two of them going. After missing the bus, Hotaru and Kokonotsu have a private conversation just as the fireworks begin. Hotaru gives Kokonotsu the winning stick, then leaves the town the next day. After Hotaru leaves town, Kokonotsu begins to miss her.
