Born of Russian descent, Millia lost both of her parents at an early age. She was thereafter adopted into a nearby Assassin Syndicate, where she practiced in the art of Hi-Deigokutsuipou, or the "Six Forbidden Magics". Using the Sixth Hi-Deigokutsuipou, "Angra", Millia's hair gained the abilities she currently possesses, enabling her to control its movement as well as alter its length and shape at will. Zato-1 practiced a similar technique, the Fifth Forbidden Magic, "Shokusei Kagejin", by sacrificing his sense of sight.
