Четвёртая война за Святой Грааль вступает в решающую фазу. Участников становится всё меньше, накал борьбы зашкаливает. Битвы уже невозможно скрыть от посторонних, и маленький городок Фуюки становится ареной для кровавой борьбы. Маги осознают, что Грааль почти в их руках, и не гнушаются никакими средствами ради победы.

Начало истории известно, ее конец близок. Остается только наблюдать, чем все завершится.

As the Fourth Holy Grail War rages on with no clear victor in sight, the remaining Servants and their Masters are called upon by Church supervisor Risei Kotomine, in order to band together and confront an impending threat that could unravel the Grail War and bring about the destruction of Fuyuki City. The uneasy truce soon collapses as Masters demonstrate that they will do anything in their power, no matter how despicable, to win.

Seeds of doubt are sown between Kiritsugu Emiya and Saber, his Servant, as their conflicting ideologies on heroism and chivalry clash. Meanwhile, an ominous bond forms between Kirei Kotomine, who still seeks to find his purpose in life, and one of the remaining Servants. As the countdown to the end of the war reaches zero, the cost of winning begins to blur the line between victory and defeat.
