俺の妹がこんなにエロゲー三昧なわけがない
“Ore no Imōto ga Konna ni Erogē Zanmai na Wake ga Nai”
“My Little Sister Can’t Be Absorbed into Eroge”

Kirino gets a long awaited eroge in the post and spends the entire day playing it, despite some frustration in the beginning when one character is cold towards her. Unfortunately for Kyosuke, who is trying to study in the next room, Kirino gets really interactive with the eroge. Meanwhile, Kuroneko stays at home and tends to her little sister, who is a Meruru fan. Elsewhere, Saori plans for a maid-themed party for Kirino and Kuroneko.
