俺の妹がこんなに可愛いわけがない

Kyousuke Kousaka is a typical high school student whose relationship with his younger sister Kirino is practically nonexistent. For years, they have lived under the same roof as distant strangers, with Kirino treating her brother with nothing but cold disdain.

This strained dynamic is shattered when Kyousuke discovers a magical girl anime DVD case in their home, which secretly contains an adult video game. His attempt to uncover the owner leads him to a shocking revelation: the secret otaku obsessed with moe anime and bishoujo games is none other than Kirino herself.

Forced into becoming her confidant, Kyousuke is dragged into Kirino's hidden world, tasked with keeping her embarrassing hobby a secret from their family while navigating the awkward and often chaotic consequences of their new, unconventional alliance.
