俺の妹がこんなに可愛いわけがない

Kyousuke Kousaka is a perfectly average high school student living in Chiba. For years, he has had a distant relationship with his younger sister Kirino, who ignores him and looks at him with contempt. Everything changes when Kyousuke accidentally discovers a DVD case of a magical girl anime at home, leading him to uncover a secret that his seemingly perfect little sister has been hiding.

Kirino is an ideal student with excellent grades and works as a professional model alongside her best friend Ayase. However, beneath her flawless exterior lies a deep passion for anime and eroge that she keeps hidden from everyone. Forced to keep her secret, Kirino introduces her brother to the otaku world, and through her, Kyousuke meets other enthusiasts like the gothic lolita Ruri Gokou and the otaku Saori Makishima. As he becomes more involved in his sister's hidden life, keeping it a secret becomes increasingly difficult.
