「聖杯戦争」の舞台として初となるアメリカ合衆国の地で、数多の魔術師〈マスター〉と英霊〈サーヴァント〉が入り乱れ、繰り広げる死闘と狂騒の物語。
A famosa Guerra do Santo Graal, onde magos (Mestres) e seus Espíritos Heroicos (Servos) batalham para conquistar o Santo Graal: um receptáculo capaz de realizar qualquer desejo. A guerra que normalmente ocorria no Japão, está ocorrendo agora em Snowfield, nos Estados Unidos da América... Mas há uma classe faltando e falsos Servos no meio... Essa será uma Guerra completamente deturpada.
In a Holy Grail War, Mages (Masters) and their Heroic Spirits (Servants) fight for the control of the Holy Grail—an omnipotent wish-granting device said to fulfill any desire. Years have passed since the end of the Fifth Holy Grail War in Japan. Now, signs portend the emergence of a new Holy Grail in the western American city of Snowfield. Sure enough, Masters and Servants begin to gather... A missing Servant class... Impossible Servant summonings... A nation shrouded in secrecy... And a city created as a battleground. In the face of such irregularities, the Holy Grail War is twisted and driven into the depth of madness. Let the curtain rise on a masquerade of humans and heroes, made to dance upon the stage of a false Holy Grail.
