You Do Not Kill Asmodeus. Now Submit to His Will

In the world so greedy and so corrupt and where the weak dies and the strong lives to take what is there's, how will this primitive, low-fantasy world of a corrupt Empire and where murder is the best solution, can handle what can be described as a literal demon king who has an army of demons and magic under his control where everyone, at best, has only a weapon of rare occurrence?

For Asmodeus, formerly a Player who, after his final thoughts playing YGGDRASIL has ended, have suddenly found himself in the anime called Akame ga Kill and, knowing the knowledge of the anime, will make sure that his goal is finally achieved: conquer this world as his true emperor and dominate every last female he can see.

For he is Asmodeus, Supreme Lord of the Nine Hells.
