There Are No Flags at the Swimming Pool
After Sena is caught playing an eroge and insists it's not perverted, Yozora has her read out the dialogue aloud to prove otherwise. Meanwhile, Kodaka's little sister, Kobato, feels jealous that Kodaka is spending more time with the Neighbors Club than with her. After encountering a swim-happy character in her game, Sena asks Kodaka to teach her how to swim. After the swimming lesson, Sena gets herself into trouble when she insults some guys hitting on her, forcing Kodaka to help her out. The incident reminds Kodaka of a friend he once had as a child, who taught him a lesson about friendship that Yozora strangely reacts to.

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?
