Fate/strange Fake - S01

A new Holy Grail War is taking shape in Snowfield, Nevada, where mages from all over the world summon Servants, heroic spirits pulled from myth and history, to fight on their behalf. But this war seems different from the ones before it. The organization behind it appears to have used data from the Fuyuki Grail War for their ritual, which leads to strange occurrences. Most participants do not know that this growing conflict is actually a fake Grail War. There is another set of seven true Servants, summoned to fight in the real Holy Grail War. One of them is a powerful Saber-class Servant who, after being summoned, saves the life of Ayaka Sajou, his apparent master. With hidden agendas and unpredictable forces at work, the line between the fake and true Grail War grows unclear, turning Snowfield into a dangerous battlefield.
