Moe, a recent graduate from a prestigious university, is on the hunt for a job when fate takes an unexpected turn. After acing a crucial interview, he finds himself in a life-altering accident that transmigrated him into a Fantasy world.

After transmigration, instead of gaining extraordinary powers, he awakens in the body of Arthur Jr., an incompetent king ruling over the small kingdom of Keldoria.

In a realm where magic is commonplace, Arthur Jr. is unable to wield any magic abilities, leaving him at a significant disadvantage. However, armed with the authority of a king and the knowledge of modern society he will transform the small kingdom of Keldoria into a advance nation where technology and magic coexist.
