On the night of Kiritsugu's death, Shirou fell asleep and woke up to a new world.

There are ghosts here, and there are swordsmen who kill ghosts.

From now on, partners of justice are no longer a borrowed slogan!

But it is a creed that you carry out throughout your life!

Ghost King, give me your life!

Infinite Holy Grail War?

Run through every one of them!
