Ore no Imouto ga Konnani Kawaii Wake ga Nai

Synopsis

While Kirino's novel becomes increasingly popular, her editor reveals that it may be adapted into an anime. Overjoyed, she invites Saori and Kuroneko with her to the anime staff meeting. However, she is shocked at the number of changes the anime staff requested, most notably changing the lead protagonist from female to male. Kirino collapses from exhaustion after returning home, so Kyosuke takes Kirino's place at the next meeting in order to plead her case. During the meeting, Kyosuke begs the anime staff to reconsider Kirino's decisions, with Kuroneko also providing her opinions, both for and against. After some back and forth, the anime staff finally agree to some of their requests. On the train ride home, Kyosuke tells Kuroneko and Saori to keep his involvement a secret from Kirino. Kuroneko questions Kyosuke's dedication to his sister and then expresses envy at having older siblings. Later, Kirino tells Kyosuke that the next life counseling will be the last.
