Girls Are Super-Cute in Yukatas
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.

Haganai
Hasegawa Kodaka has transferred schools, and he's having a hard time making friends. It doesn't help that his blond hair tends to make people think he's a delinquent. One day, he runs into his bad-tempered solitary classmate Yozora while she's talking animatedly to her imaginary friend Tomo. Realizing that neither of them have any actual friends, they decide that the best way to alter this situation is to form a club and start recruiting.
That is how "Rinjinbu", The Neighbours' Club, was formed, a club specifically designed for people who don't have very many friends. As other lonely classmates slowly join their little club, they'll try to learn how to build friendships through cooking together, playing games, and other group activities. But will this group of relationship-challenged misfits really be able to get along?
