Shirou is still lost and incredibly confused, after seeing an elegant warrior with the name Saber appear before him and choosing him as her Master. Shirou isn't even given a chance to get to grips of the situation before Saber continues her fight with Lancer, but before things get too serious Lancer walks off. Saber then chooses to pick a fight with Rin and her servant, but Saber reluctantly accepts Shirou's order to stop. Shirou then learns of the Holy Grail War, which he has gotten himself into.

Shinji says things like how he has no intention of fighting and he was just dragged into this war. He asks to make an alliance with Shirou to go after Rin but Shirou refuses. Shinji says because he doesn't know magic other Masters can't detect him so that means Shinji isn't the other Master Rin was detecting, meaning there is a fourth one at the school. Before Shirou leaves Shinji tells Shirou about how one of the Masters has set up base at a temple.Shirou gets home and is yelled at by Saber and Rin, Rin having come over after Shirou didn't come home. Shirou tells them about Shinji and the Master at the temple.Shirou and Rin both agree, against Sabers judgment, that they should not attack the temple yet as they don't know what Servant and it may be a trap.Saber brings up again with Shirou the temple but Shirou insists that they won't be going.

With the appearance of the mysterious Archer-class Servant, Saber tells Shirou to escape while keeps him occupied. However Shirou, knowning that Saber couldn't defeat him before, foolishly tries to attack him head on and with the snap of his fingers Shirou is quickly defeated. Will Saber have the strength to defeat him, esepecially now knowing his true identity; owner of all the world's treasures, the King of Heroes of ancient Uruk, Gilgamesh.Kirei Kotomine also seems to play a major part in the Holy Grail War and it's not because he's the mediator.
