Kiritsugu and his daughter Illyasviel stroll through the Einzbern woods. As Saber watches the happy parent and child, she ponders why Kiritsugu has not spoken to her since she was summoned. And in Fuyuki City, the battle ground where the Holy Grail War will be fought, the seventh and final hero is summoned.

The rules of the game have changed and the Masters have a chance to earn an extra command spell. All they have to do is find Castor and kill him.
