Plot
A.D. 2016, the foundations of humanity have been incinerated by the Mage King Solomon. Chaldea, a secret mages organization with the mission to preserve humanity's future, foresaw mankind's extinction in 2015. Thus commenced the operation to repair the Singularities in history caused by Holy Grails dispersed across time and space—Operation Grand Order. Using the Rayshift time travel technology, Chaldea's last master Ritsuka Fujimaru and his demi-servant Mash Kyrielight have traveled to and resolved six Singularities. Now, they depart for their most dangerous destination yet: a civilization in the Age of Gods, B.C. 2655 Mesopotamia. Ritsuka and Mash soon discover that Demonic Beasts roam the land with the three Goddess alliance, attacking people and towns. Amidst chaos and terror lies humanity's last defense—Uruk, a fortress city that acts as the frontline for the battle against the beasts. The battlefront is commanded by none other than King Gilgamesh, the King of Heroes, who took on the role of a mage and summoned heroic spirits to protect his city.

Production
Fate/Grand Order - Absolute Demonic Front: Babylonia was first announced on July 29, 2018 by Aniplex as an adaptation of the "Order VII: The Absolute Frontline in the War Against the Demonic Beasts: Babylonia" quest from Fate/Grand Order. Aniplex had previously launched a survey in January, asking fans what their favorite quest was, and what kind of future development they'd like to see for the franchise; the "Babylonia" quest and "TV anime" ranked first respectively. The anime is produced by CloverWorks. Toshifumi Akai is directing the series, while Miyuki Kuroki serves as assistant director, Takashi Takeuchi serves as lead character designer, Tomoaki Takase handles character designs, and Keita Haga and Ryo Kawasaki compose the series' music.

Writing
In an interview for Newtype magazine, CloverWorks producer Yūichi Fukushima stated that while the anime adaptation doesn't cover the beginning of the video game, it will be accessible even to those who don't play the game. Shizuka Kurosaki said also that "Think of each adaptation as a different take on Chaldea and the Singularity. You don't need to watch the TV series before the films."
