Reincarnated as the Villaines sister?! // KNY x F! Reader ( Y/N ) [ Ep 1 ]

Hmm what should i talk abt this series? uh.. This series is about a Collage student reincarnated as the Villaines sister of a Novel called KNY or should we say Demon Slayer it was very unexpected of her to get reincarnated especially the body of the Antagonist's (villain) sister, however she is a no evil being she is obviously trying to change the storyline and try to save those who will die, while shes at it she never noticed she made a harem herself. will she fix the problem? will she manage to change the storyline as she wanted it to be..? who knows, hopefully you all know the characters in the story it depends if i will follow the manga or the anime itself. I will be following the story sometimes, sometimes not. That's all for now.
