Rimuru City

Capital City Rimuru (中央都市リムル) or Rimuru City, in short, is the Capital City of the Jura Tempest Federation.

Trivia

 * The name of the city is "Tempest City" in Web Novel, as in the Web Novel version Rimuru managed to dissuade his followers from using his first name for the capital name, while in the canon material he failed to do so.
