The enigmatic prince from Utena's childhood. Dios's name, which means "God" in Spanish, as well as his presentation in the anime, suggest that he is to be considered Utena's guardian angel. During most of the duels, it is shown that his spirit enters Utena's body and aids her. This is an indication that Dios may have been a skilled swordsman before his imprisonment.

Despite his limited screen time, Dios is a central figure in the anime and is at the center of the plot.
