Years after the Fifth Holy Grail War in Japan, strange reports surface of one appearing in America. Attracting new Mages and Servants, the question is raised about the relic’s authenticity. As the city of Snowfield is turned into a bloody battleground, specific details seem wrong. Is it possible someone is manipulating this twisted little play, and if so, does this mean the true Holy Grail exists?
In any case, the King of Heroes
should be our biggest obstacle.
على أيّ حال، ينبغي أن يكون
ملك الأبطال عقبتنا الكُبرى
Das größte Hindernis dürfte ohnehin
der König der Helden darstellen.
El mayor obstáculo
será el Rey de Héroes.
El mayor obstáculo
será el Rey de Héroes.
Le Roi des Héros restera
notre plus grande menace.
जो भी हो, वीरों का राजा
हमारे लिए सबसे बड़ी बाधा बनेगा।
A ogni modo, il Re degli Eroi 
probabilmente sarà il nostro più grande ostacolo.
De qualquer maneira,
Ведь в любом случае
нашим главным врагом станет Царь героев.
