It is common knowledge that it is best to become an adventurer when you are as young as possible. It is common knowledge that it is best to become an adventurer when you are as young as possible, because the magical power that is the basis of an adventurer's strength will hardly grow if you don't train it while you are young. But this man, Rick Gladiator, who became an adventurer when he was over thirty years old, had the combat power of an S-rank adventurer, the highest rank in the world. In fact, Rick has lived an unimaginable life with the members of the legendary Orihalcon Fist, a party of the continent's strongest adventurers. From dragons to vampires, Rick's fighting prowess, trained by his literally "monster" mentors, allows him to defeat elite adventurers one after another who try to underestimate him.

I reincarnated into the "Villainess Eumiella" from an RPG Otome game. In the main story, Eumielle'as merely a side character, but after the ending, she reenters the story as the Hidden Boss, a character on par to the Heroes with her high stats!!

Lighting a fire in my gamer's soul, and taking advantage of being left on my own in my parent's territory, I train! Train! And at the end of my training...... By the time I enter the academy, I managed to reach level 99.

Though I had planned to live out my days as inconspicuously and peacefully as possible, soon after entering the school, I'm suspected by the Heroine and Love Interests of being the "Demon Lord"...?

A popular Web novel of seeking a peaceful life, a fantasy story of the strongest villainess!
