Sully Atraid (シュリ・アトレイド,Shuri Atoreido?) is a tomboyish girl born from the North Ambria State slums introduced in the Zero/Ao duology.
Sully traveled to Crossbell to pursue a better living. However, all she managed to struggle was living every day with irritation due to Ilya Platiere's glimmering nature compared to hers. She continuously stalked Ilya until the Special Support Section caught her. Instead of handing her Sully over to the police, Ilya found potential within her and decided to take Sully under her wing.
She has a resentment against those of wealthy status compared to her background.
