Leon Ebusci's life takes a sudden turn when he wakes up in a fantasy world where superpowers and strength control everything.
Weak people are treated unfairly or even die if they try to fight back. So, needless to say that a teenager like Leon, who hasn't done much in his life, has absolutely no chance of survival!
Starving and desperate, Leon encounters Owen—an eccentric young man with an unusual offer: join his assistant agency and complete various missions in exchange for the resources required to live a decent life.
Leon accepts, and now he must push himself to the limit in order to fullfill his new role against an ever-growing danger!
