"To be a magus is to walk with death." Years ago, his father had told him that, and Shirou thought he understood what he meant. It was only now that he understood the weight of those words. The Holy Grail War had returned to Fuyuki-the same ritual where his father's wish had un­leashed death upon the city. Shirou tried to enter the war, but the summoning failed, leaving him a powerless fool in a war of leg­ends. He is sur­rounded on all sides by those who would harm others. They wear the faces of friends-or, worse, call him brother. Yet he will fight-for the promise that he made to his father... But he will come to learn one terrible truth: No monster is more dangerous than the one who believes that they are the hero. Harem
