Cenicienta was a Daimon supervised by Kaolinite, created from the fusion of a Daimon Egg and a glass slipper. She attacked Usagi Tsukino for her Pure Heart Crystal.
Cenicienta had the appearance of a muscular, armored woman made of glass. Despite her appearance, she had a very high-pitched voice. She could transform her right arm into a sword in order to attack. She could also breathe shards of glass to render her opponents solid, or trap people inside other glass structures or walls.
