Benkei Musashibou

A warrior monk and Lancer-class Servant that Gilgamesh summoned to assist in the protection of Uruk's Northern Wall. Tales of Benkei's heroism and prowess as a fighter have spread all over Japan and much of the world, enduring even to this day. While he is a deadly warrior, Benkei also has a softer, pacifist side that hates battle of any kind.
