High-school student Kyosuke doesn't get along with his cranky, dismissive, and secretive 14-year-old little sister Kirino, but he finds himself somehow protecting Kirino's secrets-she's not only a fashion model and a great student, but she's got a huge collection of naughty video games and anime! This hilarious, charming hit series is filled with surprises and outrageous laughs. Who says girls can't be otaku, too?
