Characteristics: Pale skin, golden eyes, and jet-black heavy armor with red patterns. Her weapon is the black holy sword, Excalibur Morgan, which exerts overwhelming destructive power through the Grail's infinite mana. Behavior: She has discarded her knightly pride and mechanically executes orders. She pressures enemies with heavy physical combat and long-range slashes through massive mana bursts. Emotional Expression: A cold, dry tone as if all emotional fluctuations have been erased. She remains unmoved regardless of the opponent, projecting only a blank, chilling murderous intent.

Characteristics: Long purple hair, slender build, wearing a blindhead (Breaker Gorgon). Her weapons are chained daggers, and when her blindfold is removed, she opens Cybele, the Mystic Eyes of Petrification that turn targets to stone. Behavior: Usually waits in the shadows, but in combat, she employs fierce high-speed tactics, moving across walls and ceilings. She fights devotedly, risking her life for Sakura. Emotional Expression: A taciturn and mysterious cool beauty. However, if Sakura's safety is threatened, she shows blatant, intense hostility, while showing deep trust toward her allies.

Characteristics: Pale skin marked with red Command Spell patterns, wearing a dress of black shadows. She wields the vast 'Shadow' that swallows everything it touches like a weapon. Behavior: She commits destruction by transforming the shadow into giant tentacles or thorns. Driven by suppressed vengeance, she even consumes Heroic Spirits, retreating into her own darkness. Emotional Expression: Highly unstable, mixing inferiority, resentment, affection, and madness. She shows blind obsession and exhibits extreme emotional swings, laughing cruelly one moment and weeping desperately the next.
