Natasza Maraskova, arch-nemesis of Gossamer Swan.
Pascaline's rival during their ballet school days. Natasza was originally set to star as Odette in the upcoming Swan Lake ballet, but then a freak accident scalds the left side of her face rendering her completely blind in that eye, and was unable to fulfill her role. Predictably, Pasca is given the role and goes on to achieve major success. Embittered, Natasza disappeared from the public eye for a time.
