Noble Phantasm- Song of Grail

The Dark Holy Grail

Avenger (アヴェンジャー, Avenjā?) is an Avenger-class Servant who appears in the Fourth Holy Grail War of Fate/Zero and in the Grand Orders of Fate/Grand Order.



Avenger's True Name is Black Iri (黒アイリ, Kuro Airi?), formed through Angra Mainyu possessing the remnants of Irisviel von Einzbern's personality in the Greater Grail. Manifested in the Grand Orders, she takes on the persona of Justeaze Lizrich von Einzbern, but can rather be said to be the remnants of the Greater Grail tainted by All the World's Evils, the Black Holy Grail (黒聖杯, Kuro Seihai?), in contrast to the other Irisviel manifesting as a "White Holy Grail."





As the Servants are slain, Irisviel von Einzbern's body begins to deteriorate, with only Avalon's power enabling her to function. After the sacred scabbard is transferred into Kiritsugu, Irisviel is abducted by Berserker and taken to Kirei Kotomine, who interrogates her as to Kiritsugu Emiya's motives. Angered by her answer, Kirei kills her, her body transforming into a large golden goblet. Irisviel's consciousness is subsumed by Avenger, as black mud begins pouring out of the goblet and flooding the room.

When Kiritsugu is drenched in the Grail Mud, Avenger assumes Irisviel's form and personality in order to communicate with him. Kiritsugu is horrified by the revelation that his methods killed more people than they saved and rejects Avenger, killing its projections of Irisviel and Illya. Avenger then curses him to live a life of despair and misfortune, eventually leading to Kiritsugu's death.

In the Einzbern Consultation Room metafictional shorts, Avenger impersonates Irisviel, tutoring T-chan on the basics of the Holy Grail War and ostensibly consoling the vanquished Servants so that they can pass on without regrets, though she takes sadistic delight in driving them to despair - as with Diarmuid Ua Duibhne. She is revealed to be a manifestation of Avenger by Lancelot, and extends her shadow in a manner similar to the Shadow in an attempt to consume him before being stopped by, though this brief contact corrupts him into his Berserker state.

In the 2014 anime adaptation of Unlimited Blade Works, Avenger manifests before Illya in the form of her mother, telling her that Kiritsugu abandoned them and urging her to seek revenge.
