Based on the classic 1991 manga by Riku Sanjo and Koji Inada, this beloved shonen series centers on Dai, a boy raised on a peaceful island who sets out to confront a resurrected demon lord threatening the world. As he fights alongside companions old and new, he gradually uncovers his own mysterious lineage and the hidden truth behind the forces of evil. It remains a foundational title in Japanese pop culture, with its characters and imagery still recognizable across Tokyo's anime merchandise shops and themed cafes today.
