The Eminence in Shadow is a dark fantasy isekai light novel and manga series by Daisuke Aizawa with illustrations by Tozai and manga art by Anri Sakano, published in English by Yen Press, blending overpowered fantasy, parody, and secret-organization tropes.
Cid Kagenou has always dreamed of being a shadowy mastermind pulling the strings from behind the scenes; not the hero, but the one secretly in control. After being reborn in a fantasy world, he finally gets his chance… even if most of what he thinks is roleplay turns out to be real. As he builds a secret organization and fights hidden enemies, the story balances absurd comedy with surprisingly serious stakes. The Eminence in Shadow thrives on dramatic irony, where only Cid doesn’t realize how real everything has become.
