Yakume wo Hatashita Hiyage no Yuusha wa, Henkyou de Jiyuu ni Ikiteimasu

Clay was the baggage carrier for the prince's hero party—yet he defeated the Demon King alone. Wanting to stay out of the way and let the future king take the glory, he disappears. Returning to life as a simple villager, Clay heads to the "Hell's Frontier" (Henkyoku), a land everyone else has abandoned. Using his skills "Appraisal" and "Imitate," he absorbed the techniques of the hero party and now possesses overwhelming power. He begins freely taming this monster-infested, uncharted land. But his former comrades, enemies, and others won't just leave the true hero alone.
