Murabito desu ga Nani ka?

I'm the strongest damn villager on the planet! Reincarnated into a fantasy world, Ryuuto Maclaine was assigned the most ordinary class of all: villager. No heroic bloodline, no divine blessings—just a dirt-poor farm boy from a no-name village. His childhood friends? Oh, just a cheat-tier hero named Cordelia and a genius sage named Moses. At fifteen, Ryuuto's life comes to an abrupt end... Courtesy of Moses stabbing him in the back. But death isn't the end. That's when his true cheat kicks in: return from death—a one-time-only skill that lets him rewind his life in this world. Armed with his second chance and an indomitable will called unyielding, Ryuuto vows to rise again. Even if he's just a villager, he'll save the hero, rewrite his fate, and punch his way to the top! The rise of Ryuuto the villager begins now—try to keep up. (Source: Hanashi Media)
