Level 1 Demon Lord & One Room Hero - S01

After the final battle that decided humanity's fate, the hero Max and his companions defeat the mighty Demon Lord. As he dies, the fallen Maou swears to come back stronger and take his revenge. Ten years later, the Maou returns, but his resurrection is incomplete-he's stuck in the body of a child. Eager to settle the score, he seeks out his old nemesis, only to find that the once-great hero who saved the world has become a lazy, washed-up mess. Disappointed but undeterred, the Maou moves in with Max, determined to restore him to his former glory. Yet as he learns more about what happened in those missing years, he begins to suspect there's a deeper reason behind Max's fall-one he doesn't yet understand.
