Marcus, a professional MMA fighter, wakes up in the world of his favorite RPG—only to discover a major handicap. Bound by an absolute rule, he is forbidden from using any main weapons of the game, leaving him to rely solely on his martial arts skills, deep game knowledge, craftiness and sharp instincts. As he battles monsters, navigates dangerous quests, and faces off against overpowered foes, he must find a way to reach level 80 and prove that raw martial skill and tricks can triumph over this rule. Can Marcus break the system, or will the game break him first?
