Cinnamon is Chocolat's mother and a famous witch. She was a previous Queen Candidate along with her friend Candy Mieux. Under circumstances not clearly explained in the manga, Cinnamon went to visit Glacé, the grand duke of darkness, while Candy took over as queen.
In Volume 7, it is revealed that Cinnamon had Chocolat around this time, and that Chocolat's father is the King of the Ogres himself. Cinnamon was actually Pierre's familiar who had her voice taken away. Cinnamon fights against Glacé at the end of Volume 8, but stays behind with him as he fades away.
