The fireworks festival is coming up again, and the three of them are planning to go together. They're planning to eat at the same restaurant that nakamura and san used to go to when they were young, and they're also planning to meet up with a girl named Kukai-san, who they haven't seen in a long time. The girl is named Solami, and she's from the same neighborhood as the other two characters. She's sad, but she doesn't know who her parents are.
