One of the seven strongest people on the continent, the King of Mercenaries. He started a war to avenge his fallen family and destroyed territory but failed and lost his life. However… “Wow, I’m alive?” I returned to the past, back through time. A perfect opportunity to right my regrets and reverse everything. It doesn’t matter if people around me point fingers, calling me a scoundrel, or dismiss me as tr*sh. Because… “I’ve got a plan.” “What plan?” “A plan to destroy everything.” There won’t be a second failure. This time, I’ll wipe out all my enemies. …But first, I need to rebuild this damn estate.

I was reborn as the villainous daughter, Yumiela Dolknes, in the world of an otome RPG game. Yumiela only had a small role in the original story, but after defeating the Demon King, she will appear as the Hidden Boss with a bonus specs to solo fight the Hero party.

Having a gamer-spirit, I’ve been raising my level since I was a child. By the time I enter the academy where the game stage is, I was level 99.

I wanted the heroine and the capture targets to defeat the Demon King, but they just flirted around and didn’t raise their level. Moreover, they treat me as if I’m the Demon King just because I have dark hair and use dark magic.

It’s a story where I aim for peaceful days.
