- Description from novelbuddy

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.

A little ruffian who fought recklessly without any morals and bottomline accidentally time-traveled to parallel space and became a Key Case Investigation Team agent. The huge change in identity had him creating chaos in the police station. However, a strange miracle system helped him repeatedly solve mysterious cases, turning him into an impudent ruffian detective!

This was the era that belonged to various powerful bloodline warriors, the fervorous era where magic powers and warrior energies were the deciding factor of dominance! With endless ardour and unstoppable courage, a grassroot nobody could also shine and live like a boss!
