A gag comedy about a delinquent reincarnated to lead the Demon Lord's army.
A man who lived his life as a delinquent is suddenly reincarnated into another world as the Demon Lord!? In a world of swords and magic where monsters, humans, heroes, and assassins clash, he lives a carefree life while being jerked around by a cast of characters with personalities and abilities that are far too eccentric. A slapstick isekai fantasy filled with both serious moments and gags.
