Fate/strange Fake - S01

"Fate/strange Fake" revolves around a flawed imitation of the Holy Grail War, modeled after the Third Holy Grail War in Fuyuki. After the original war ended, a group of American mages-separate from the London-based Mage’s Association-used data from Fuyuki’s Grail War to design their own ritual. Decades later, they chose the city of Snowfield as the Sacred Land for their version of the war. But their replication was incomplete, resulting in a distorted ritual: the Saber class was missing, and the loosened definition of a "hero" allowed for the summoning of unusual Servants. Rohngall and his apprentice, Faldeus, are sent by the Mage’s Association to investigate Snowfield and the state of the war. Faldeus, secretly a spy for the American organization, has Rohngall assassinated upon arrival-even knowing Rohngall is a puppet. He claims their Holy Grail War has been in the works and is genuine, stirring up controversy at the Clock Tower, and aims to "promote" the project to the Association.
