In the Nevada desert base of “Snowfield,” a terrifying Holy Grail War is raging, proving to be one of the strangest wars of all time. Here, powerful figures from around the world have summoned the ancient Servants of Myth and Law to their aid. But the point is that what’s happening in Nevada this time is completely out of control. It is revealed that some secret organization has stolen the data of the old “Fuyuki” battle and made a poor attempt to copy it, due to which the entire ritual has been disrupted and strange and terrible incidents are happening everywhere.
The real shock comes when it is revealed that this entire Maidan-e-Jung is just a “hoax” – a fake Grail War. Participants are being fooled while behind the scenes a “True Holy Grail War” is also going on where seven real and extremely dangerous Servants have been sent to the field. One of them is a true “Saber-class” warrior who saves his Master, Ayaka Sajou, from the jaws of death. Now Snowfield has become a web of death where the conspiracies are so deep that it’s difficult to distinguish who is real and who is fake. A new betrayal and death lurk at every step!
