Seeking the power of the Holy Grail, something that can make miracles occur, seven different mages summon seven Heroes, and fight until the last man remains--a battle of epic proportions, the Holy Grail War. In preparation for the war, various participants are chosen from all over the globe. Eight years ago in Einzbern Castle in Germany, a girl named Illyasviel is born. Her father, Kiritsugu Emiya, embraces her knowing he will be part of the battle, as well.

The mystery of the mass kidnappings in Fuyuki remains unsolved, with more kids disappearing daily. When Tohsaka Rin can't get in touch with her friend Kotone, she braves the darkness and enters the city on her own to search for her. That's when she spots a strange man leading two kids around and decides to follow him...

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.

Natalia has raised Kiritsugu since rescuing him from the island. He has followed her in every step in becoming an assassin. Over the years their relationship has grown to the point of mother and child, so what Kiritsugu does next is…

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?
