Winter's Days, Fateful Night
#01
Shirou Emiya’s life was saved by Kiritsugu Emiya during the great Fuyuki City fire ten years ago. After school one day, he witnesses a battle between two Servants. Lancer, who realized that someone has been watching this battle that should not be seen, tries to kill Shirou on his Master’s orders.
Shirou was resuscitated by Rin, but he is attacked by Lancer again that night. While Shirou bears the brunt of Lancer’s attacks, a Servant is summoned in front of his eyes.
