The series uses elements from all five of the live-action Fantaghirò films, combining and rearranging various events and characters appearances. The main theme throughout the series is the love between Princess Fantaghirò and King Romualdo, which changes and affects everyone around them. The main villains throughout the series are the Black Witch and her master, the lord of evil Darken, both of whom appear from the very first episode. Various places and people that were not named in the films have been given names in the cartoon adaptation, such as the kingdoms of Tuan and Dana, which are Fantaghirò and Romualdo's respective home kingdoms.
