Rin suspects Kuzuki might be the Master of Caster. With the help of a hesitant Shirou, she implements a dangerous plan in a remote location to test out her theory.

Caster keeps Saber hostage, but Kuzuki is not happy with his Servant calling her own shots. Rin, determined to take out Caster and her Master, orders Archer to take out Kuzuki. Will Archer do as she says?

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.

Rin and Shirou begin their battle against Caster and Kuzuki while Lancer faces off with Archer. Will Rin's plan work in the end?

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!

Together with Saber and Lancer, Shirou is set out to rescue Rin. Will he be able to beat Archer in a battle?

Rin is helpless now in Kirei's hands, while Shirou faces Archer. Is he skillful enough to defeat 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.

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