Opening Act - S1.E3

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.
