Synopsis of Kage no Jitsuryokusha noch Naritakute!
Great heroes and diabolical villains are the kind of characters people crave, but that's not the case with Cid Kagenou. He aspires to become the mastermind behind it all, to pull the strings and get his machinations to advance the whole story. In his previous life in Japan he could not achieve his goals, but now, reborn in a world of magic, he will show the true Eminence of the Shadow!
While Cid pretends to be just another filler character, he is recruiting members of his (fake) organization "Shadow Garden" with the aim of ending a mysterious cult that lurks in the shadows. His (wrong) organization against the disgusting (but surprisingly real) cult of Diabolos.
