Synopsis:
I was reincarnated as a villain daughter Yumiera in the RPG maiden game. But in fact, Yumiera is a shobo in the main story, but after the ending, it is a character that reappears as a back boss and crosses the hero -transcendental high spec!
As a result of the gamer's soul on the fire and training, I had reached level 99 when I entered the school.
Regardless of the story of the game, I'm not noticeable, but I'm going to spend a peaceful time, but as soon as I entered the level, the levels of the heroine and the capture targets were suspected of being the Demon King ...!?!?!?
