The Eminence in Shadow: Season 1 (Blu-ray)

Cid doesn't want to be a flashy hero or a dastardly villain. He wants to operate in the shadows and pull the strings of society through wit and cleverness. So, when he's isekai'd to another world armed with magic powers (and an overactive imagination), he forms Shadow Garden, an underground organization that fights an evil cult he totally made up. But while Cid happily roleplays his favorite antihero tropes, little does he know Shadow Garden's recruits treat his every lie as gospel, and worse yet? That "fake" cult is actually real, and they're not happy his power fantasy just impeded their plan to gain ultimate power in THE EMINENCE IN SHADOW!
