The club decides to go to a matsuri festival for the purpose of getting takoyaki, which Kodaka is passionate about. While picking out a yukata, Kodaka explains to Sena about why he doesn't dye his hair. After having their fill of food, Yozora and Sena compete with each other at the stalls, before everyone gets together to set off some fireworks. After the last one is set off, Yozora's hair catches on fire, forcing Kodaka throw to a bucket of water on her to put it out. Soaked and humiliated, Yozora leaves and stays away from the club for the last week before school. When the new school term comes, Yozora arrives with her hair cut short, leading Kodaka to finally recognise her as his childhood friend.
