All the servants have been summoned and now it is a game of spy vs spy. Who will be the first to take the initiative in Fuyuki City?

A car screams down the moonlit streets of Fuyuki City, with a very happy-go-lucky Irisviel behind the wheel and a slightly unnerved Saber sitting next to her. The evening takes a bad turn when a mysterious shadow darts in front of them. The person claims to be Saber's loyal retainer, yet Saber has no memory of them...

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.

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.
