The Unified Demon Realm was largely brought together under the leadership of the Thirteenth Demon King and their followers. During the reigns of the Fourteenth and the radical Fifteenth Demon Kings, the Demon Realm, divided for over a thousand years, was finally unified in full.

The Unified Demon Realm is a nation made up of multiple races, with demons as its dominant race. Since the Seventeenth Demon King, born among the undead, was elected to the throne, this has generally been regarded as a sign of progress in the Demon Realm's attitudes toward other races.
The Seventeenth Demon King of the Unified Demon Realm is now on strike.
