Amazing female leads! (in another world/a novel/otome game and more)

At the age of eight, I realised I had reincarnated as the last boss of an otome game, Queen Pryde. Her fighting strength is high because she's the last boss who will fight with the capture target, and her cunning wits make her the most powerful first princess in a matriarchal country. What awaits her is a future of ruination! In this case, I'll avoid destruction from the capture target and freely use my authority and cheat abilities to save everyone!

My personal fav!

“Please, Hilise. Please die in place of Gabrielle.” My always dignified brother begged me for the first time. He wants me to die for our stepsister, whom we don’t even share a drop of blood with. I’ve always been miserable, and there is no exception this time. This was the seventh time that I was betrayed and killed. “I’m glad that you’re a scumbag until the end.” This/Next time I'll abandon them first.

I LOVE THIS FL
