Candy Mieux holds the position of the reigning queen in the magical kingdom and is the mother of Vanilla Mieux. Her birthday is April 8, and she stands 165 cm tall. Her pastime is playing the harp. She does not have any strong dislikes, though if she were to name something, it would be a heart that is suffering.

Candy came to power after winning the royal examination against Cinnamon Meilleure, the mother of Chocolat Meilleure. During the story, she is actively working to promote peace between the magical kingdom and the ogres.

Her role in the main narrative is significant, particularly in her efforts to support Chocolat. To send her heart to Chocolat, Candy transformed into a spirit and bestowed her power upon her. This act left her vulnerable, and she was weakened by an attack from Captain Glacier. However, in the anime adaptation, she survives this encounter, similarly to Cinnamon Meilleure.

One of her most notable actions occurs during the coronation ceremony for the new queen. When Chocolat expressed her wish to return to the human world, Candy granted her permission to go, accompanied by Vanilla. This decision reflects her development into a wise and supportive figure who understands the needs of the younger generation, moving beyond her role as a distant sovereign. Her key relationships are defined by her position as Vanilla's mother, her former rivalry with Cinnamon, and her spiritual mentorship of Chocolat. Her notable abilities include the power to project herself as a spirit and transfer her magical energy to another person across great distances.
