When i first found this manga just from the title maou i expected it to be the typical hero trying to beat the demon king kind of story however it isn't.This series is heavily politically just the summary should tell you that instead of the typical hero and demon king fighting this breaks that cliche in the first chapter.The demon queen convinces the hero that their fight will do nothing for the world whether the humans or demons win the war.The human society was literally depending on the war to continue for it to survive if it stopped many people would starve to death and millions of people would die.This is something i have never seen a series like this explore nobody ever considers what happens after the war that is why i like this series.And it continues from that to the demon queen trying to work towards humans and demons some day coexisted.This series displays a lot about economics.If you want something different this is a series you should check out.
