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.

Rider and Waver make a trip into town, and stop in a bookstore along the way. There, Waver reads a biography on Rider's life and learns why he aimed to conquer the far east. Meanwhile, Caster and Ryuunosuke return to their destroyed base. A conversation with his Master leads Caster to an epiphany, and with insanity in his heart, the mad magician begins casting a certain spell...

Rider is shifting Caster into his Reality Marble to buy some time. He asks the other Heroes to come up with a plan to finish Caster off. A phone call from Kiritsugu gives them a fighting chance, but it comes down to Lancer making a difficult choice.

As a child, Kiritsugu lived on a small island with his father Nori. Nori's magical work with flowers has captured the attention of a local girl.

Irisviel time is running out and Kiritsugu is doing what he can to make her comfortable. But the game continues and he leaves to eliminate his next target. A surprise attack against his hideout leaves him a man down and heart broken.

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

As commanded by Kiritsugu, Saber unleashes her Noble Phantasm on the Holy Grail, with a completely unexpected result. Who will end up winning the war?
