My Little Sister Is a Bad Girl

While everyone else goes to high school to study, he heads to an all-girls school to make his name in the underworld.

The male protagonist is forced to transfer to an all-girls delinquent school, where he just happens to end up in the same class as his younger sister.

Every girl in the class is trouble. Fights and chaos are rampant, and the school is split into rival factions locked in endless conflict.

As he brings the school’s delinquent queen bees under his control, one by one, he takes charge of the chaotic girls’ school and kicks off an entirely different kind of high-octane campus story.
