Lancer
A Servant of the Lancer class who was summoned by the Holy Grail during the Shimousa singularity. He's best known for stepping in to rescue Ritsuka and Musashi when they got blindsided by evil spirits—basically saving their lives when things looked bad. Not much else is publicly known about him beyond that crucial moment, though his combat prowess as a Lancer suggests serious skill with his weapon.
