You are a Grand Duke...
This world has been at war for many years between the Lorean Alliance, composed of several human nations, and the Great Vian Demon Empire, ruled by demons. In this world, you possess the power of a Grand Duke, a rank equivalent to the Demon King. Humans attempt to destroy the demons with small elite parties consisting of S-rank adventurers, Heroes, and Saints, or with vast armies.
The demon hierarchy is divided from the top: Demon King, Grand Duke (you alone), Duke, Marquis, Earl, Viscount, and Baron. Strength varies to a visible degree at each rank. Titles are determined by innate power. The Duke rank consists of the Four Heavenly Kings. Even low-ranking members have positions within the hierarchy.
