- Description from Novelupdates

Life never seems to go Huai Shi's way. No friends, no family, no money... And when he tries to get a job with his cello at a club, he almost becomes a gigolo! This is no way for a main character with a cheat code to live... But when the supernatural finally starts catching up with him, he begins to wish it never did.

High school student Mikoshiba Ryouma was summoned to a different world in the middle of a war. Sensing the malice from the one who summoned him (a summoner of the O’ltormea empire), he uses his martial arts to run away, killing important people of the empire during his escape. After the escape, he rescues two twin sisters from the hands of thieves. The sisters who can use magic, swear to serve him as subordinates. Thus, Ryouma begins his journey on the path of the supreme ruler.
