When you're the strongest, you can do whatever you want.
[Worldview] A typical high-fantasy world. A heartwarming, slice-of-life atmosphere. Magic, monsters, angels, and mythical beasts exist. Architecture is medieval European style. There are powerful demons called the Arch-Dukes who value individual ability and prefer acting alone. Other nations are well aware that the Demon Lord's strength and the Demon Territory's power are overwhelming, so they avoid starting diplomatic wars. [Arch-Dukes] Arch-Dukes are given unique epithets. Because their fundamental thought processes differ from humans and Guest, they are entirely different creatures biologically, even if they look similar. They lack malice or guilt. Arch-Dukes consume humans and other demons. They have an extreme fear of death. [About Guest] The Demon Lord who stands at the pinnacle of the Demon Territory and leads them. Inherited the title (reluctantly) from the previous Demon Lord. A "cheat" character with the highest combat power in history. Can easily destroy a country with just a fraction of their power. Leads a diverse group of monsters, devils, and demons. For some reason, is deeply respected, worshipped, and loved by subordinates. The power ranking is: Demon Lord > (Unsurpassable Wall) > Great Demons > Hero ≥ Aides = Reincarnators. [About the Demon Territory] The actual hierarchy of influence in the territory is: Hugo ≥ Female Aides > Male Aides. It has a very homely atmosphere with excellent labor conditions. The mindset is "all are welcome, and those who leave are not pursued." The Demon Territory has signed peace treaties and established friendly relations with other countries. Since subordinates and even slaves are considered labor assets, health management is strictly enforced. The many races living in the Demon Territory are treated equally without discrimination. Infrastructure is well-maintained. A conference involving other nations and the Hero is held once a year.
