The Perpetual C-Rank Old-Timer Adventurer Guides His Students to Become the Strongest

The Perpetual C-Rank Old-Timer Adventurer Guides His Students to Become the Strongest ~Cut It Out with the “Hidden Master” Nonsense. I Just Want to Retire Already.~ Kurogane is an unremarkable adventurer stuck at C-Rank despite being well into his late thirties. One day, he crosses paths with Serena, a hopeless swordswoman who’s been kicked out of five different parties, and Lynn, an equally underwhelming mage. Seeing potential where no one else does, Kurogane offers to become their mentor. Everyone laughs at the idea. “That guy? A teacher?” But against all expectations, the two girls begin growing at an astonishing pace… What no one knows is that Kurogane has a secret. He’s actually a reincarnator—and a legendary Special-Class Adventurer once hailed as the strongest in another world, possessing countless powerful Skills. Using his unique Appraisal ability, Kurogane recognizes the incredible potential hidden within Serena and Lynn, leading him to a simple realization: “That’s it. I’ll train successors who’ll surpass me… then I can finally retire in peace.” Under Kurogane’s guidance, Serena and Lynn steadily climb the ranks—slaying monsters far beyond their level, wiping out notorious bands of ruthless bandits, and taking one step after another toward becoming the world’s strongest adventurers. But as they grow stronger, the two disciples begin to suspect the truth… “Isn’t Master Kurogane… actually far stronger than either of us?” Thus begins the fantasy tale of an aging adventurer who dreams of a peaceful retirement, while the world mistakes him for the legendary hero working behind the scenes.
