Cosette Weinberg/Parvis

Cosette is a beautiful, petite lady with a fair, immaculate face and clear, distinctive features. She has waist-length wavy hair and bangs that fall to each side like her mother's, while both her hair and eye color were inherited from her father, leading some people to believe that she is the Grand Duke's true lost daughter. She has blonde hair and red eyes. Cosette is shown to have a kind, bright, and approachable demeanor towards everyone she meets. She is friendly and helpful, even to those who are of a lower status. Her social rank in high society rose considerably with more and more people believing that she was the true daughter of the Grand Duke, while also looking down on the heartless fake. She was a woman who couldn't seem to kill a single insect, but strangely when you look into her eyes, it gives you goosebumps.

Oblivious to her true nature, Cosette is manipulative, cunning, and meticulous, where she gains influence over people with her kindness and casts them aside when they are of no use or if they make mistakes that may damage her reputation. She feigns innocence, to give the impression of being "harmless" and often loses her cool when something or someone takes advantage of her plans. Her stories of her former life as a commoner lessened the worries of those in the same position, causing them to relate and empathize with each other.
