Ore no Imouto ga Konna ni Kawaii Wake ga Nai

Trama

Kyousuke Kousaka, a 17-year-old high school student, has a distant relationship with his 14-year-old sister, Kirino, who has largely ignored him for years. This changes when Kyousuke discovers a DVD case for a magical girl anime, Hoshikuzu Witch Merle, which secretly contains an adult video game titled Imouto to Koishiyo! (Love with Little Sister!). Suspecting a family member, Kyousuke subtly probes during dinner, only to be met with strong disapproval from his anti-otaku father. Later that night, Kirino confronts Kyousuke, revealing her extensive hidden collection of moe anime and lolicon bishoujo games.
