Higeki no Genkyou tonaru Saikyou Gedou Rasubosu Joou wa Tami no Tame ni Tsukushimasu

At the age of eight, I realised I had reincarnated as the nefarious 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 superior cunning wits make her the most powerful first princess in a matriarchal country. Since she brings misfortune to all that surrounds her, what awaits is a future of ruination! ...really, wouldn't it be better if I died?
