With rules being broken and new players entering the tournament, the remaining Heroes and Masters are entering a new phase of the tournament. What Tokiomi does next will affect everyone.

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…

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.

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.

The end of the battle is drawing near and relationships between Masters and Servants are changing. Many players have dropped off the field, and a very special one is next to go.

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?
