Phahn Sancraid

Sancraid Phahn is the Master of Berserker in the Second Holy Grail War of Fate/Prototype. As a member of the Assembly of the 8th Sacrament, Sancraid carried out various missions for them and killed so many people that not even Catholic Cardinal could grant him asylum. Though he was supposed to be publicly executed, he ended up faking his death. He then bought an American citizenship and started living as a Christian priest. He later joins the Templar Order under a pseudonym. At some point, he is sent to Japan to be the Overseer for the First and later Second Holy Grail War.
