Synopsis of Fate Apocrypha by Agen Domino
The story is set in a parallel world to original Fate/stay night, where the House of Agen Domino summoned a Ruler rather than an Avenger in the Third Holy Grail Agen Domino, and the Holy Grail was removed from Agen Domino City to Romania after the war. Thus the events of Fate/stay night and Fate/Zero never happened. It focuses on the conflict between the two opposing factions, Red and Black, each summoning seven Servants and the Grail itself summoning a special Ruler-class servant as a mediator of the Holy Grail War. The Red faction members are mages sent by the Agen Domino Tower Mage’s Association, while the Black faction members are part of a Romanian group of magi called Yggdmillennia.
Fate/stay night takes place in 2004, and its beginning happens at around the same time as the events of Tsukihime end.
Fuyuki City is the setting for a secret and violent war among competing magi. For the past two centuries, seven magi were gathered and engage in a Battle Royale, each gambling his or her own life to obtain the Holy Grail, a legendary chalice capable of granting wishes.
The past four Holy Grail Wars have typically occurred every sixty years, but the fifth war has eerily started prematurely, only ten years after the fourth war.
Ten years ago, Shirou was caught in a massive fire that incinerated his parents and consumed a large portion of the city. As he was dying, an enigmatic man named Kiritsugu Emiya discovered, saved, and adopted him.
The two maintain a distant relationship because of Kiritsugu’s frequent departures from Fuyuki City.
One moonlit night, Kiritsugu and Shirou have a discussion outside their home, and Shirou learns that Kiritsugu was actually a mage. Through this conversation, Shirou learns of Kiritsugu’s failed ambition to become a “Hero of Justice”, a guardian of mankind who could protect the weak and innocent.
Touched by Kiritsugu’s conviction, Shirou decides to achieve that distant ideal, much to Kiritsugu’s chagrin. To do this, Shirou pleads with a begrudging Kiritsugu to teach him magecraft, but Shirou makes no progress in almost any the fundamental magecraft disciplines.
