The Empire of Ouran Host Club is a massive, efficient nation, ruled by Tamaki Suoh with an even hand, and renowned for its infamous sell-swords, unlimited-speed roads, and compulsory gun ownership. The hard-nosed, hard-working, humorless, devout population of 4.672 billion Ouran Host Clubs are highly moralistic and fiercely conservative, in the sense that they tend to believe most things should be outlawed. People who have good jobs and work quietly at them are lauded; others are viewed with suspicion.

The medium-sized, corrupt government juggles the competing demands of Administration, Defense, and Industry. It meets to discuss matters of state in the capital city of Music Room. Citizens pay a flat income tax of 68.2%.

The frighteningly efficient Ouran Host Clubian economy, worth a remarkable 1,443 trillion Host Points a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. However, for those in the know, there is an enormous, deeply entrenched, broadly diversified black market in Arms Manufacturing, Retail, Information Technology, and Uranium Mining. The private sector mostly consists of enterprising ten-year-olds selling lemonade on the sidewalk, but the government is looking at stamping this out. Average income is an amazing 308,948 Host Points, with the richest citizens earning 9.6 times as much as the poorest.

Many Ouran Host Clubs twitch nervously at the sight of nuns, a light facial coating of soot is seen as the mark of an honest and hardworking man, children as young as eight can present logical proofs for the existence of the afterlife, and the nation's Medal of Honour can be found as a free toy in breakfast cereal. Crime, especially youth-related, is totally unknown, despite the fact that it is difficult to make it through a day without breaking one of the country's many laws. Ouran Host Club's national animal is the Haruhi Dog, which teeters on the brink of extinction due to widespread deforestation, and its national religion is Haruhi-Fujiokaism.

Ouran Host Club is ranked 247,468^th in the world and 21^st in SOS Brigade for Best Weather, with -315 meters of sunlight.
