(Yosuga No Sora) My Yandere Little Brother Fell for Me

This is a story about gender-bending, a descent into darkness, and a sweet, naive girl. Haruno Yuu, a transmigrated girl who never amounted to much, returns to a quiet country town with her frail (?) and adorable younger brother. What she doesn't know is that her brother is secretly a yandere. So when the energetic Yuu decides to throw herself into the arms of her friends, her little brother turns dark.

Sora: \(+++ω+++) Big Sis, let's do something fun~

Yuu: Σ(ﾟдﾟlll) Huh?! Wh-what?!!

P.S. 1. The heroine has no idea that the legendary [beep] anime Yosuga no Sora exists, so the plot takes a wild turn. (I'm not sticking to canon, so don't come after me.)

2. Imouto Sora becomes little brother Sora. (Yep, that's my weird sense of fun.)

3. The heroine was reborn into this world as a baby. She doesn't have the original Yuu's personality; she's a clumsy, tomboyish girl, and she's strong, too.

4. There are no female rivals. Yep, just like in the original story, all the girls fall for Yuu.
