Fate/Stay Night

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.
