I was reborn as the daughter of the villain, Yumiela Dolknes, in the world of an RPG otome game. Yumiela had a minor role in the original story, but after defeating the Demon King, she appears as a Hidden Boss with bonus stats to solo fight a group of heroes. Since I have a gaming spirit, I have been leveling up since childhood. And by the time I entered the Academy, where the game begins, I reached level 99. I wanted the heroine and love interests to defeat the Demon King, but they just flirt with each other without caring about leveling up. Moreover, they treat me as if I am the Demon King just because I have black hair and can use dark magic. This story is about my desire to achieve peaceful days.
