Rin Tohsaka, a young girl, finds her father's memento. All she has is a catalyst and a pendant. She sets out to summon Saber, a powerful spirit.

Rin and Shirou run into a girl named Illyasviel von Einzbern. She has a Servant who is a big mad monster! What does this girl want from them?

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?

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

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

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

The Holy Grail War is over... The dust has settled... What awaits Rin and Shirou on their next journey?

An alternative ending. The final battle has ended, Saber still exists, and Shirou awakes to a peaceful sunny day.
