Demonopolis is a city, possibly the capital city, in Demon World. Little is seen of the city itself when Shion visits to safe the people of Monster World, as he soon moves out of town to the Pitcastle lair of Grimomen. While there, Shion does make a trip to The Shame Inn, where the warrior questions loyal Grimomen supporter Drum about the Dark Lord's whereabouts. The return trip is barely seen, with Shion and the villagers appearing right in front of Schwartz and Egger, Demon World's immigration control.
