Fate/strange Fake: Whispers of Dawn

Synopsis:
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.
