Adventurer’s Trainer for the Adventurer with Hidden Gifted in Beginners Town

“You’re useless now. Get out of here already!” Aroze, a Trainer gifted with the rare ability to boost the growth rates of others and provide versatile support magic, brought their hero party to max level in just three years. However, once the party decided his skills were no longer needed, they unceremoniously kicked him out. Brokenhearted, Aroze returns to his hometown—a starter town for rookie adventurers—and decides to live a quiet, low-profile life. But one day, a young girl knocks on his door. “Please, make me stronger with your Trainer skills!” The girl is a fledgling adventurer rejected by every party due to her slow growth rate. Feeling sorry for her, Aroze reluctantly agrees to help. To his surprise, the girl turns out to be an extraordinary talent who grows at an astonishing pace, rivaling even the heroes, with just a bit of his guidance. Soon, word spreads, and other rookie adventurers with ridiculous potential start flocking to Aroze for help. As he trains them and helps them overcome their limitations, his once-quiet life turns into something entirely unexpected, earning him the title of The Starter Town’s Trainer. Meanwhile, the hero party that Aroze raised to max level but failed to properly train in actual combat ignores his warnings and recklessly challenges the Demon Lord’s army—only to face utter devastation.
