Despite losing Saber, Shirou is determined to fight. Since Caster is protected by Kuzuki and Archer, Shirou and Rin decide to team up with another Master. Left with no other option, they set out to find Illyasviel and Berserker.

Shirou and Rin finally reach the castle where Illyasviel and Berserker are. However, there are other unexpected guests visiting Illyasviel.

Shirou is devastated since he was unable to save Illyasviel. Together with Rin, he is determined to fight Caster and the others. Out of the blue, they are visited by a Servant who is willing to lend a hand!

Now that Archer is no longer Rin's Servant, he is determined to kill Shirou. However, Shirou is not afraid of him. Rin and Saber are willing to do anything to stop Archer!

Shirou's battle with Archer continues. But then an unexpected visitor appears, and new information unfolds.

Wishing to avenge Archer and destroy the Holy Grail once and for all, Rin and Shirou consider their options and try to come up with a strategy.

While Saber faces off against the guard at the gate, Shirou and Rin try to destroy the Holy Grail!

With everything seeming to be against them, will Shirou and Rin be able to survive?
