Kurt is a young prince born from the union of a goddess and an Earthman. From his divine origins, he inherited a Herculean strength, but he ignores this origin, until he was 10 years old, when he discovered his mother's status. She has been transformed by the witch Medusa and only the latter can restore her life. Kurt therefore goes in search of the witch with the intention of defeating her and finding his mother. During his journey, he will meet many people, including Leon, a little dragon, and Orie, a little fortune teller.
