The position of the Maou (Demon King) is not determined by social standing or heredity. They are decided by Shinou's word and one day a messenger suddenly appears to call on them. Usually once their term as maou is done they return to their hometowns and live the rest of their days as normal.
There were 26 Maous before Yuuri, making Yuuri the 27th Demon King of Shin Makoku.
