People aspire to be great heroes and evil villains, but Cid Kagenou is not one of them. He aspires to be the true brain behind it all, pulling the strings and directing the entire plot. He was unable to attain his objectives in his prior existence in modern-day Japan. But now, resurrected into a magical world, he will demonstrate the true majesty of darkness! As Cid poses as an ordinary mobster, he recruits members for his (false) group Shadow Garden, which aims to bring down the enigmatic cult that lurks in the shadows. Cid leads his (fictional) organization against the filthy (yet unexpectedly real) Diabolos Cult with plenty of ad-libs.
