Hasegawa Kodaka, a boy with few friends, along with his beautiful classmate, the oddball Mikazuki Yozora, form the Neighbors Club, a group dedicated to making friends. While this sounds innocent enough, the only people who end up joining the club are total freaks and outcasts. Together, they geek out over RPG games, pit imaginary friends against each other, and wreak havoc in one another's lives while struggling to build social skills. Can black sheep like these really learn to become friends? And for a hot-blooded guy like Kodaka, why must everyone else in the club be females who are so attractive yet so insane?!
