Excuse me, what AD year is it?

Yeah, as you may guess, I come from the future!

Chaldea

In the future there's a Holy Grail War that broke out in Chaldea. Everything is burned down! Everyone gone!

Just rest in peace already!

Chaldea has already burned down and you died at the Holy Grail War!

What are you blabbering about?

In addition, due to some circumstances at compiling the tankōbon, we're likely to end it halfway through!

Believe it or not, it's the truth!

Don't believe such an unscientific thing like a spirit.

Let's go with my time travel theory instead.
