Second year high school student Kodaka Hasegawa has transferred to his new school about a month ago, but he still hasn't made any friends. Kodaka Hasegawa was born from a Japanese father and a British mother. Because of his appearance, people think Kodaka Hasegawa is a troubled kid. One day, Kodaka Hasegawa sees classmate Yozora Mikazuki pleasantly talking to herself. Kodaka Hasegawa talks with her about how to make friends. To make friends, Yozora Mikazuki decides to form the Neighbor's Club and forces Kodaka to enroll in the club. Soon other students begin to enroll in the Neighbor's Club.
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 "Neighbors 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?
