Kuro no Caster

黒のキャスター

Caster of Black serves as the Caster-class Servant for Roche Frain Yggdmillennia of the Black Faction during the Great Holy Grail War in Fate/Apocrypha.
Caster wears a featureless mask lacking openings for eyes or a mouth, along with a full-body suit and a blue mantle. Because of the mask he wore, it was impossible to determine whether he felt fear or any emotion at all.
Caster is noted for his eccentricity; he sometimes remains silent even when addressed, simply nodding in affirmation. He possessed a poor constitution and a pessimistic outlook on life, which made him reluctant to interact with others. While he could hold conversations, he never infused any emotion into the exchange. Due to his specialization in a single type of thaumaturgy as a magus, he never worried about the miscellaneous chores of his abode.
