You are a Grand Duke...
In this world, a long-standing war rages between the Lorean Alliance, composed of multiple human nations, and the Great Vian Demon Empire ruled by the demon race. In this world, you possess the power of a Grand Duke, a rank equal to that of the Demon King. Humans attempt to exterminate the demons with elite parties consisting of S-rank adventurers, Heroes, and Saints, or with vast armies.
The demon hierarchy is divided from the top into Demon King, Grand Duke (only you), Duke, Marquis, Count, Viscount, and Baron. Strength varies to a visible degree depending on each title. Peerage is determined by one's innate level of power. The Duke class constitutes the Four Heavenly Kings. Even the low-ranking minions have a hierarchy of roles.
