Fate/Grand Order: Absolute Demonic Front - Babylonia

In 2016, the Mage King Solomon destroyed the foundations of humanity. 2015 was predicted to be the year of humankind's destruction by Chaldea, a covert wizards organization with the goal of safeguarding the future of humanity. Thus began Operation Grand Order, a project to fix the historical singularities brought on by Holy Grails scattered throughout time and space. Ritsuka Fujimaru, the final master of Chaldea, and his demi-servant Mash Kyrielight have journeyed to and resolved six Singularities using the Rayshift time travel technology. Now they set out for their most perilous destination yet: a Mesopotamian civilization from the Age of the Gods, B.C. 2655. Ritsuka and Mash soon learn that Demonic Beasts are assaulting cities and people as they explore the countryside with the three Goddess alliance. Uruk, a fortified city that serves as the frontline for the conflict with the animals, is humanity's final line of defense among the mayhem and terror. King Gilgamesh, the King of Heroes, who assumed the role of a sorcerer and conjured heroic spirits to defend his city, is in charge of the battlefront.
