It is generally advised that individuals should pursue a career as an adventurer when they are young because the magical abilities that form the foundation of their strength will not fully develop if not trained during this period. However, there is an exception in the case of Rick Gladiator, who became an adventurer at the age of over thirty and possesses the combat power of an S-rank adventurer, which is the highest rank globally. Despite his late start, Rick has led a remarkable life alongside the members of the legendary Orihalcon Fist, one of the strongest adventuring parties on the continent. His fighting skills, honed by monstrous mentors, have enabled him to defeat numerous elite adventurers who underestimated him. From dragons to vampires, Rick's unparalleled combat abilities make him a force to be reckoned with in the world of adventure.
