Lord Demon King

Demon kings are powerful and terrifying existences in people's minds. Their appearance means that the world is about to be destroyed, but that is only in the past. The current demon kings are either squatting at home or working as great harem kings. Because of this, the great king who gave them power cannot stand it anymore, so the king chooses a person from countless worlds and lets the chosen person destroy the world. Let those demon kings who do things that are not what demon kings should do, become truly great and terrifying demon kings. This novel and its characters are purely fictitious.
