The Phantom Thief of Utsugi Uyu is a mammoth, efficient nation, ruled by Utsugi Uyu with an even hand, and notable for its multi-spousal wedding ceremonies, compulsory vegetarianism, and punitive income tax rates. The hard-nosed, humorless, devout population of 9.86 billion Utsugi Uyuans have some civil rights, but not too many, enjoy the freedom to spend their money however they like, to a point, and take part in free and open elections, although not too often.

The enormous government juggles the competing demands of Administration, Law & Order, and Industry. It meets to discuss matters of state in the capital city of Hideout. Citizens pay a flat income tax of 67.9%.

The powerhouse Utsugi Uyuan economy, worth 651 trillion yen 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 a slick, highly efficient black market in Woodchip Exports, Furniture Restoration, 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 66,072 yen, with the richest citizens earning 9.7 times as much as the poorest.

Books are often used as kindling, not even adulthood can save you from truant officers, teachers regularly paddle unruly students, and captains must wait until all rats are safe before jumping ship. Crime, especially youth-related, is totally unknown, thanks to a very well-funded police force and progressive social policies in education and welfare. Utsugi Uyu's national animal is the fancy pigeon, which teeters on the brink of extinction due to toxic air pollution.

Utsugi Uyu is ranked 298,652^nd in the world and 3,659^th in Remembrance for Smartest Citizens, with 4.97 quips per hour.
