Fate/Grand Order: Absolute Demonic Front - Babylonia Initium Iter

Fate/Grand Order: Absolute Demonic Front - Babylonia Initium Iter is a special prologue episode to the anime adaptation of the Babylonia chapter of Fate/Grand Order.

The year is 2010 AD. Romani Archaman has just been posted to Chaldea, the secret organization devoted to observing and safeguarding the future of humanity. There he becomes the primary doctor of a young girl, Mash Kyrielight, Chaldea's second successful summoning experiment, who has spent her whole life within the facility's walls. Mash knows little of the outside world and is curious about many things, especially the word "Senpai."

The interaction between the doctor and the girl gives Mash a reason to hope, and that hope gradually spreads like a wave. Set years before the events of the game's main story, the episode quietly shows how the bond between Dr. Roman and Mash began. It is also the beginning of your story, the story of an ordinary "somebody," standing at the start of a journey that weaves the future.
