After a tragic fire claims his family, Shirou is taken in by Kiritsugu Emiya, who imparts upon him the art of magic and righteousness. Years later, while cleaning at school, Shirou unwittingly stumbles into a deadly clash between two powerful beings called Servants. In a bid to flee, he sustains grave injuries but miraculously survives, only to face imminent danger as the same Servant hunts him down. In a desperate move, Shirou summons his own Servant, the knight Saber, plunging them both into the Fifth Holy Grail War. This brutal competition involves seven Servants and their mage masters vying for the ultimate prize—the all-powerful Holy Grail. As Shirou grapples with his conflicting ideals of heroism and survival, he questions whether he can uphold his beliefs in a harsh world of bloodshed. Will he follow in his foster father's heroic footsteps, or meet a tragic end in his pursuit of justice and glory?
