Рін Тосака, молода дівчина, знаходить записки свого батька. Маючи лише каталізатор і кулон, вона ставить собі за ціль викликати Сейбер, могутнього духа.

Shirou Emiya is a high school student who always helps people around him whenever he has a spare moment. His dream has always been to become a hero of justice. One night, he stumbles upon a battle between two Servants...

Rin finally asks Shirou out on a date, but their enjoyment is cut short when Caster makes her move. Shirou is forced to make a difficult decision to protect the people he cares about.

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 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!

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?
