Synopsis

Seven mages summon seven legendary heroes to fight for the Holy Grail—a legendary artifact said to grant any miracle. This is the fourth iteration of a brutal competition that's been postponed and restarted multiple times. The battleground: Fuyuki City. Among the participants is Kotomine Kirei, a priest and mage who feels adrift. He doesn't understand why he was chosen for this war, or what he's even fighting for. Everything changes when fate throws him against Emiya Kiritsugu—a ruthless man willing to do anything, question nothing, and destroy anyone in his path to claim the Grail's power. This is the Fourth Holy Grail War from ten years before the events of Fate/stay night. It's the untold story behind the clash between Shirou's adoptive father and Rin's father, and the origins of a younger Kotomine Kirei. The truth finally comes to light.
