Fate/strange Fake

The series follows the story of an incomplete Holy Grail war that took place in Snowfield, USA. The American Magi Association stole some ritual information from the third Holy Grail war in Fuyuki and tried to make their own. After seventy years, they are ready to practice that in the city of Snowfield. Due to incorrectly performed rituals, a strange servant appeared, and the saber class was missing. To search for them, Magi sent some people, but they got into a war with them.
