Sylvie is the "songbird" of the Dandelion Troupe; her beautiful voice and sexy looks captivate her audience wherever she goes. Sylvie is sort of an older sister figure for Nadja while they are on the road, good at giving Nadja advice, and is someone Nadja can turn to with her emotional problems.

Sylvie can be frivolous at times; she's vain about her looks, likes going shopping, like other girls her age, and at one point she is seen dating Antonio Fabiani, a very shady character. But she also has romantic problems of her own; she suffers an unrequited love for Raphael, a traveling musician and friend of the Dandelion Troupe, who currently cannot correspond her feelings due to his past. Sylvie is also a good fighter, thanks to her ability to use her umbrella as a weapon.
