Shirô 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!
