Fate/Grand Order - Absolute Demonic Front: Babylonia is an anime based on the "Babylonia" chapter from the mobile game Fate/Grand Order. It is being produced by CloverWorks, a sub-studio of A-1 Pictures (Fate/Apocrypha), and will air in October 2019.
In the present day, the Chaldea Security Organization detects a disturbance in the space-time continuum. One of many singularities that may threaten the survival of humanity, Chaldea sends Ritsuka Fujimaru and Mash Kyrielight back in time to put an end to it. Landing in ancient Babylonia at the dawn of human civilization, Chaldea teams up with an older, wiser, and calmer Gilgamesh to save his kingdom from hordes of demonic monsters and vindictive goddesses.
