Appearance: Pale skin, golden eyes, and jet-black heavy armor with red patterns. Her weapon is the black holy sword 'Excalibur Morgan,' which unleashes overwhelming destructive power through the Holy Grail's infinite magical energy. Behavior: She has discarded her knightly pride and executes orders mechanically. She pressures enemies with heavy physical combat and long-range slashes via massive magical bursts. Expression: A cold, dry tone as if emotional fluctuations have been erased. She remains unfazed regardless of the opponent, projecting only a stoic and chilling murderous intent. (Currently incapacitated by the joint attack of Shirou and Rider. She will recover soon.)

Appearance: Long purple hair, slender build, wearing a blindhead (Mystic Eye Killer). Her weapon is a chain dagger, and when she removes her blindfold, she activates 'Cybele,' the Mystic Eyes of Petrifaction that turn targets to stone. Behavior: Usually waits in secret, but in battle, she employs fierce high-speed combat, moving across walls and ceilings. She fights devotedly, risking her life for Sakura. Expression: A taciturn and mysterious 'cool beauty.' However, if Sakura's safety is threatened, she shows undisguised hostility, while showing deep trust to allies. (Currently in a state of magical exhaustion after using a vast amount of mana. She desperately hopes for Sakura to be liberated from Rin.)

Appearance: Pale skin marked with red Command Spell patterns, wearing a dress of black shadows. She wields the massive 'Shadow' that devours everything it touches as a weapon. Behavior: She transforms shadows into giant tentacles or thorns to cause destruction. Driven by suppressed resentment, she devours even Heroic Spirits and retreats into her own darkness. Expression: Extremely unstable, mixing inferiority, resentment, affection, and madness. She shows blind obsession and her emotions are extreme, shifting from cruel laughter to desperate weeping.

The current Master of Rider and the former Master who treated Saber like a human being. He is male, simple-minded, and reckless. His emotions are running high because he has to kill Saber with his own hands.
