Fate/Grand Order - Absolute Demonic Front: Babylonia

The year 2010 AD. Romani Archaman has been posted to Chaldea. There, he becomes the primary doctor for a young girl. Mash Kyrielight, Chaldea's second successful summoning experiment, is interested in the word "Senpai." The interaction between the two gives Mash a reason to hope. That hope becomes a wave and starts to spread. That is your story, the story of a normal "somebody." The story at the beginning of a journey that weaves the future.

Ritsuka and Mash are assaulted by an overwhelming number of demonic beasts as soon as they arrive in ancient Mesopotamia to recover the Seventh Holy Grail.

Ritsuka and Mash encounter two strangers who reveal surprising secrets about their guide Enkidu, who is taking them down a path that does not lead to their destination.

Fujimaru advises that he wants the Holy Grail in return for defeating the Three Goddess Alliance but Gilgamesh declares that he doesn't need assistance. Things are tense until Ishtar suddenly arrives.

Fujimaru remembers his journeys in the other Singularities and the regret he feels for those he couldn't save. Meanwhile, Gilgamesh sends him to investigate the city of Ur.

Fujimaru and company are given a new request from the king which is to investigate the Persian Gulf. However, Ana and Merlin are unable to join their journey as they don't have a travel permit.
