The eighth and current head of the Einzbern family. He wasn't around during Justica's era, but he has kept himself alive for nearly two centuries by continuously prolonging his life. He has a white beard that makes one think of a frozen waterfall, and Emiya Kiritsugu notices an astute light from his eyes that makes it impossible to see any senility and constantly brings about a feeling of bias and pressure every time Acht's gaze meets him.

With the promise of granting any wish, the omnipotent Holy Grail triggered three wars in the past, each too cruel and fierce to leave a victor. In spite of that, the wealthy Einzbern family is confident that the Fourth Holy Grail War will be different; namely, with a vessel of the Holy Grail now in their grasp. Solely for this reason, the much hated "Magus Killer" Kiritsugu Emiya is hired by the Einzberns, with marriage to their only daughter Irisviel as binding contract.
 
Kiritsugu now stands at the center of a cutthroat game of survival, facing off against six other participants, each armed with an ancient familiar, and fueled by unique desires and ideals. Accompanied by his own familiar, Saber, the notorious mercenary soon finds his greatest opponent in Kirei Kotomine, a priest who seeks salvation from the emptiness within himself in pursuit of Kiritsugu.
 
Based on the light novel written by Gen Urobuchi, Fate/Zero depicts the events of the Fourth Holy Grail War—10 years prior to Fate/stay night. Witness a battle royale in which no one is guaranteed to survive.

In that battle whose conclusion was postponed three times, now, the fourth war commenced again. Entrusting their dearest wish of victory, the magi joined the battleground called "Fuyuki", but amongst them, there was a man who was always alone, and could not find out the meaning behind his fights. His name was Kotomine Kirei. Not comprehending the guidance of fate, Kirei was lost, and had kept questioning. Why someone like his was given the Command Seals. However, the fate of his fights crossed Kirei's path with a nemesis by chance. That person is - Emiya Kiritsugu. A man who was sterner than anyone else, more merciless than anyone else, and who sought the miracle of the Holy Grail.

Based on the third route of Fate/stay night.

Fate/mahjong night Seihai Sensou is a parody manga. It combines elements of Fate/stay night and the game Mahjong.

A gag manga featuring numerous characters from various Type-Moon works in a school setting.


The setting of Fate/Apocrypha is a parallel world to Fate/stay night where the Greater Grail was removed from Fuyuki after the Third Holy Grail War and disappeared for many years. Around the 2000s, around the same time as the Fifth Holy Grail War would have happened, the group that plundered the Grail, Yggdmillennia, openly declares their secession from the Mage's Association and that they are in possession of the Grail. The Association dispatches fifty magi to retrieve it, but all but one are instantly slaughtered by Lancer of Black. The one remaining manages to activate the reserve system of the Greater Grail, allowing for the summoning of fourteen Servants in total. 

This marks the start of the Great Holy Grail War in Trifas, featuring two different factions, the Black Faction, whose members are part of Yggdramillennia, and the Red Faction, whose members were sent by the Mage's Association with the exception of one from the Church. The Grail itself also summons Ruler to act as a mediator of the Holy Grail War.

The stage: the city of Snowfield in the western U.S., far from Fuyuki. There, a "false Holy Grail War", quite unlike the original Holy Grail War, unfolds. There were those who had been keeping an eye on the auguries of the Holy Grail in Snowfield. According to an investigation by the Mage's Association, the Holy Grail War system in Snowfield was an imitation of the one in Fuyuki. What's more, the system was incomplete, leading to the exclusion of one of the seven classes and the selection of beings as Servants who ordinarily could not be summoned. It was, verily, a strange fake. As an organ of the U.S. government executes its various plots, the Servants are summoned one after another...
