The Demon Slayer of MiroSan is a titanic, efficient nation, ruled by Hisui with an iron fist, and renowned for its deadly medical pandemics, triple-decker prams, and frequent executions. The hard-nosed, cynical, humorless, devout population of 12.895 billion MiroSanians are ruled without fear or favor by a psychotic dictator, who outlaws just about everything and refers to the populace as "my little playthings."

The medium-sized, corrupt, well-organized government juggles the competing demands of Administration, Education, and Law & Order. It meets to discuss matters of state in the capital city of Tokyo. The average income tax rate is 70.0%, and even higher for the wealthy.

The frighteningly efficient MiroSanian economy, worth a remarkable 2,568 trillion mons 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, fairly diversified black market in Arms Manufacturing, Information Technology, Uranium Mining, and Automobile Manufacturing. 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 impressive 199,155 mons, and evenly distributed, with the richest citizens earning only 2.9 times as much as the poorest.

The deceased are buried mostly to hide them from state-sanctioned corpse-collectors, a politician who is photographed pulling a funny face while eating can say goodbye to their credibility, religious bigotry is not allowed but bigotry against theism is encouraged, and spiritual tourists meditate in the ruins of MiroSanian cathedrals. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. MiroSan's national animal is the dog, which teeters on the brink of extinction due to widespread deforestation, and its national religion is Cards.

MiroSan is ranked 11,246^th in the world and 11^th in Temporary Home for Highest Average Incomes, with 199,155.27 Standard Monetary Units.
