Fate/Zero  

The "Holy Grail" is a legendary artifact that grants miraculous powers. In this story, seven magicians summon seven heroic spirits to fight for it in a contest known as the War of the Holy Grail. However, the conclusion of the war was postponed three times until the fourth one began again. The magi chose Fuyuki as their battleground and among them was Kotomine Kirei, who struggled to understand his purpose in the fight. He questioned why he had been given command seals when he didn't comprehend fate's guidance. By chance, he encountered Emiya Kiritsugu, a man known for being stern and merciless, who sought the same miracle as Kotomine Kirei. This story takes place 10 years ago in Fate/stay night, where the truth behind the battle between Shirou's father, Rin's father, and young Kotomine Kirei is finally revealed.
