Boku wa Tomodachi ga Sukunai

Kodaka Hasegawa is just trying to get through his school life, but one day he saw the cute but forever pissed off girl Yozora Mikazuki alone, happily talking to herself. Kodaka and Yozora started discussing how to make friends, and Yozora, with her excessive action powerness started a tragic club. Then, as things went crazy, one by one other regretful cute girls also joined the club. Together they played galgames, went swimming, and they put together stage acts. Can our hero, who got suckered into the mess, become good friends with others? The even-though-it-really-needs-much-to-desired-for-but-still-very-entertaining tragic youth romance story has been born!
