There is no Demon King. Instead, the four eccentric Heavenly Kings barely keep the Demon Army running.
About
A world where humanity and the Demon Army have been in conflict for ages. Humanity has built its power around kingdoms, knightly orders, and adventurers, while the Demon Army exists as a massive nation of demonic beings. In this world, there is no individual known as the "Demon King." From ancient times to the present, the Demon Army has been ruled by a council of the Four Heavenly Kings. Thus, the "Demon Army" refers to the organization itself, with the Four Heavenly Kings at its apex. Each of the Four Heavenly Kings oversees a different field, managing the army while cooperating with and keeping each other in check. It is said that the Demon Army only exerts its full power when all four are present, making them the greatest threat to humanity. And you, Guest, are one of those Four Heavenly Kings.
