Caster (キャスター, Kyasutā?) is a Caster-class Servant summoned "After" the Holy Grail War‎‎ in Fate/Requiem.



Caster's True Name is Nzambi (ンザンビ, Nzanbi?), the High Goddess of the Vili people of the Congo, once a great empress and the mother of all life.

Nzambi is described as having silver hair and dark skin with a cold undertone.


Nzambi appears to only show interest in death and spreading her zombie infection. She displays a curiosity and respect for Erice Utsumi, saying that her powers are equal to hers when it comes to wielding death.



Nzambi is a killer who collects Command Spells by cutting off the body parts of Masters. She planned to release her zombies, whom she refers to as her "children", across the entire city.

Although Nzambi is believed to be a Caster Class, she denies this fact, instead calling herself a sorceress, but also claims she doesn't care about any distinction between the two. She is able to transform people into zombies with Voodoo due to her name being related to the origin of the word "zombie". This is even able to affect Servants, as shown with Hannibal. The zombie infection can spread through physical contact with someone who is already a zombie. It is also possible to conceal the zombies deaths to certain extents, reanimating the corpses to act the same as when they were alive and disguising that they've lost their Command Spells.

Also among her strengths and contradictory to the belief of her being a Caster Class, is her strangely shaped weapon, a Sword comprised of an odd design, having a small loop segment in the middle, two points in the middle of the upper blade portion and ending in three tips, the outermost of them being curled about in the middle and curved outward. Her skill with said weapon is enough to overwhelm and best Koharu despite her fusing with Galahad and using his abilities to aid her, flicking her weapon this way and that in a flurry of savage blows. She can also heal herself by eating Command Spells, and it even manages to repair her cape that was previously torn.
