The Ikaruga of Shizuna Rem Misurugi is a mammoth, orderly nation, ruled by Divine Blade of Silver with an iron fist, and renowned for its rum-swilling pirates, keen interest in outer space, and national health service. The hard-nosed, cynical, devout population of 6.394 billion Ikaruga are ruled with an iron fist by the dictatorship government, which ensures that no-one outside the party gets too rich. In their personal lives, however, citizens are relatively unoppressed; it remains to be seen whether this is because the government genuinely cares about its people, or if it hasn't gotten around to stamping out civil rights yet.

The relatively small, corrupt, well-organized government is primarily concerned with Defense, with Industry, Education, and Environment also on the agenda, while International Aid and Social Policy receive no funds. It meets to discuss matters of state in the capital city of Setsugetsuka. The average income tax rate is 55.1%, and even higher for the wealthy.

The frighteningly efficient Ikaruga economy, worth a remarkable 1,539 trillion miras a year, is broadly diversified and mostly comprised of black market activity, especially in Arms Manufacturing, Information Technology, Retail, and Tourism. State-owned companies are reasonably common. Average income is an amazing 240,707 miras, and evenly distributed, with the richest citizens earning only 2.2 times as much as the poorest.

Celebrity chefs are thought to be the progenitors of all food, billion-mira sentient AI killbots roll through the streets dispensing hot dogs and T-shirts, unpopular scientists are shunned by name, and the treehouse in Ikaru Park is the tallest building in Shizuna Rem Misurugi. Crime, especially youth-related, is all-pervasive, probably because of the absence of a police force. Shizuna Rem Misurugi's national animal is the ikaru, which frolics freely in the nation's many lush forests, and its national religion is Silver Princess.

Shizuna Rem Misurugi is ranked 245,026^th in the world and 1^st in Ikaruga for Largest Insurance Industry, scoring -5.57 on the Risk Expulsion Effectiveness Rating.
