Reborn as Harry Potter's sister, the scumbag counterattacks and slaps the wizarding world in the face!
Harry Potter's sister Finny Potter was reborn, but her world was dark - the beatings from her aunt and uncle, the cold eyes from her brother, and Voldemort's conspiracy. Everyone regarded her as an abandoned child, and even her classmates at Hogwarts secretly laughed at her behind her back. The only ones who were nice to her were the Malfoys and his son? They seem to remember the memories of their previous lives and become loyal "doglegs". But she didn't even bother!
Until one day, Voldemort proposed to her with a face full of infatuation - and she smiled! She slapped him hard and said coldly: "Are you worthy?" From then on, she began to counterattack all those who had looked down on her, stepping on their corpses to reach the top! The overlord of the wizarding world? If he dares to chase her, he must be prepared - her revenge will start from "Chasing the Wife in the Crematorium", where she will torture the scum and slap her in the face, it's so exciting!
I think it's actually pretty average.
