Battle rages throughout Einzbern Castle: Kayneth's magical mercury sphere versus Kiritsugu's formidable gun arsenal, Saber and Lancer join forces against Caster in the forest, and Irisviel detects a new enemy as she and Maiya make their escape.

With all the Heroes exhausted from their win against Caster, Saber has challenged Lancer to a final battle. A battle fought with honor and respect between two Knights. Kiri doesn’t care for honor or respect, he will win by any means necessary and tonight he shows how far he will go.

Saber is hot on the trail of Rider, much to his delight. Meanwhile, Kiritsugu sets off on a different lead. The new player, Matou Kariya, watches in the background as his play unfolds perfectly.

Two heroes, two masters, one grail; a winner will be decided.
