More accurately, it's a slice-of-life manga/anime about an otaku club at a Univeristy in Japan. The main protagonist is Kanji Sasahara, who starts out his first year at college wondering if he should join the manga club or the anime club. He loves both, but is still so shy about admitting his otaku-hood that he can't bring himself to join either. Then he discovers Genshiken, the really hardcore otaku club. As they say, hilarity ensues as Sasahara discovers who he truely is through the exploration of his hobbies.
