Dragon Quest: The Adventure of Dai

The story unfolds on Delmurin Island, a haven for monsters freed from the control of the defeated demon lord Hadlar. Dai, the only human on the island, is raised by the monster Brass and aspires to be a hero. His life changes when Hadlar is resurrected, revealing he now serves a more powerful demon lord. The hero Avan arrives to train Dai, but Hadlar attacks, seeking to kill Avan. To protect his students, Avan uses a Self-Sacrifice spell, but fails to defeat Hadlar. Just as Dai and Avan's other student, Pop, face certain doom, Dai awakens a hidden power, gaining superpowers and repelling Hadlar. Dai and Pop then embark on a journey to avenge Avan and bring peace back to the world, facing the threat of the new, more powerful demon lord.
