Fate/Grand Order - Absolute Demonic Front: Babylonia

A.D. 2017 The last era in which Magecraft still existed. Society was created by human hands, but Mages grasped the truth of the world. Magecraft is comprised of techniques from past humans that cannot be explained by science, while science encompasses the techniques of future humans that Magecraft cannot achieve. Researchers and scholars of both Magecraft and science have been gathered to maintain human civilization under the Chaldea Security Organization. But calculations then proved the extinction of humanity in 2019. The cause of this is “realms that cannot be observed” that suddenly appeared in various eras of history, called “Singularities”. Ritsuka Fujimaru, the one Master remaining in Chaldea, has been intervening within these Singularites, alongside the Demi-Servant Mash Kyrielight. He has been attending to the forbidden rituals to resolve or destroy the Singularities: the “Grand Order”.
