Fate/stay night: Unlimited Blade Works Season 1 Episode 1 Prologue

Shirou Emiya is an ordinary high school student who lost his parents in a fire when he was young. Despite the traumatic experience, he has developed a strong sense of justice and desires to help others. One night, he witnesses a battle between two powerful warriors. In this battle, Archer, a mysterious man in red clothes, saves Shirou from a powerful creature. However, the warrior who was fighting against Archer, another man in black clothes, escapes.

After the encounter, Shirou returns to his normal life, but he cannot shake off the strange experience. The next day, he meets his classmate Rin Tohsaka, who is also a powerful mage, and learns that the battle he witnessed was a battle between mages for the Holy Grail.
