The production staff for The Eminence in Shadow includes Kazuya Nakanishi (Comic Girls assistant director, Vivid Strike! main animator) as director, Kanichi Katou (Those Snow White Notes) as series composer, and Makoto Iino (Suppose a Kid from the Last Dungeon Boonies Moved to a Starter Town) as character designer. Nexus is handling the animation production for the series.

The original light novel series is written by Daisuke Aizawa with illustrations from Azunishi. It was first published by Kadokawa in November 2018 after starting out as a web novel on Shousetsuka ni Narou. Four volumes have been published as of February 2021 under the Enterbrain label. The light novels have also inspired a manga adaptation by Sakano Anri and a comedic manga spin-off by Seta U. 

Yen Press releases both the light novels and manga adaptation in English. It describes the story as:

Even in his past life, Cid’s dream wasn’t to become a protagonist or a final boss. He’d rather lie low as a minor character until it’s prime time to reveal he’s a mastermind…or at least, do the next best thing-pretend to be one! And now that he’s been reborn into another world, he’s ready to set the perfect conditions to live out his dreams to the fullest. Armed with his overactive imagination, Cid jokingly recruits members to his organization and makes up a whole backstory about an evil cult that they need to take down. Well, as luck would have it, these imaginary adversaries turn out to be the real deal-and everyone knows the truth but him!
