Assassin's True Name is Gray (グレイ?), the young assistant of Lord El-Melloi II. Gray was to be the flesh of King Arthur. When she was born, her facial features vaguely resembled those of King Arthur, but with the years, her body suddenly changed to that of King Arthur's. Losing her true face, she could no longer differentiate her own existence from that of King Arthur. Because of this, she could never fully understand herself. Upon hearing the news, Lord El-Melloi II, visited the village, and due to circumstances, Gray was entrusted to El Melloi, who made her his apprentice; admitting her to the Clock Tower of London.
Assassin takes on the appearance of Gray in all of her forms. She herself retains the scythe Rhongomyniad as her personal weapon.
