Full Summary

In a fantasy world teeming with magic, monsters, and guilds of adventurers, most people begin their careers as adventurers in their teens. Strength is built with youth, and reputation rises with experience. But what happens when a middle-aged man decides to break into the scene—starting from zero?

“Shinmai Ossan Boukensha” tells the unconventional and charming story of Rick Gladiator, a 30-something-year-old man who, despite his age, registers as a rookie adventurer. Unlike his peers, he didn’t train in his youth, nor did he join a guild in his prime. Instead, he spent years undergoing relentless training with one of the most powerful adventuring parties in the world: the Orichalcum Fist.

This wasn’t just any party—it was a group of superhuman warriors who trained Rick with absurd, borderline lethal methods. He ran through blizzards, fought dragons barehanded, and was beaten into shape—literally. The result? Rick emerges not as an average newcomer, but as an unstoppable monster of a man, ready to dominate the adventuring world.


The Twist: Old Rookie, Unmatched Strength

Rick may look like an average, humble middle-aged guy with short gray hair and a gentle smile, but he’s anything but average. Upon registering as an adventurer, guild staff and other adventurers laugh him off. Who starts this kind of career at 30+?

But the moment Rick steps into battle, everything changes.

He crushes monsters with a single blow, shatters boulders, and moves with the speed and precision of a master. He’s so powerful that seasoned adventurers mistake him for a high-ranking legend in disguise. Rick, however, remains kind-hearted, polite, and slightly clueless about just how absurd his strength really is.
