*Somewhere in the modern world*
Zelretch: I have no idea why I'm doing this, trololol, but I have found an anomaly in the past; one that involves a certain King from the Fifth Holy Grail War.

Anyway, you are to find the cause of this anomaly, and see to it that it is corrected. How? I have absolutely no idea!
Emiya Shirou: Wait, wha—
Zelretch: Bye!
*Somewhere in King Arthur times*
Emiya Shirou: … t. (Shirou looks around, confused). Now what do I… (there was a distant rumbling, like a great storm upon the earth, breaking it apart with the fury of its thundering).

To answer the summary (warning: spoilers!): Nope.
