Fate/stay night chronicles a two-week period in the life of the protagonist Shirō Emiya, an amateur magus who attends a school named Homurahara Gakuen in Fuyuki City, Japan. The story primarily takes place at and around Shirō Emiya's house, which acts as his base location in the Holy Grail War. Outside of Shirō's house, frequented locations include Homurahara Gakuen (the high school), and the Ryūdō Temple.
The main theme in Fate/stay night is "conquering oneself". There are three story lines in the visual novel; each has a different theme. The first one, Fate, is the "oneself as an ideal". The second one, Unlimited Blade Works, is "struggling with oneself as an ideal". The third one, Heaven's Feel, is "the friction with real and ideal"
