CV: Takahiro Sakurai
The Servant that Gilgamesh called forth from a Heroic Spirit summoning. His class is Caster. His true nature is the court mage appearing in the Legend of King Arthur, and a hybrid born between a human and an incubus. He stands at the highest rank in terms of his abilities as a Mage, and possesses Clairvoyance—“the eyes that overlook the world”.
