The Empire of Koedo is a titanic, socially progressive nation, ruled by Kazuto Kirigaya with an iron fist, and renowned for its barren, inhospitable landscape, compulsory military service, and complete lack of prisons. The hard-nosed, hard-working, cynical population of 15.486 billion Aincradians are ruled by a mostly-benevolent dictator, who grants the populace the freedom to live their own lives but watches carefully for anyone to slip up.

The medium-sized, well-organized government prioritizes Defense, although Law & Order, Administration, and Welfare are also considered important, while Spirituality and International Aid receive no funds. It meets to discuss matters of state in the capital city of Kirito City. Citizens pay a flat income tax of 21.1%.

The strong Aincradian economy, worth 861 trillion Yen a year, is fairly diversified and led by the Woodchip Exports industry, with major contributions from Book Publishing, Arms Manufacturing, and Gambling. Average income is 55,600 Yen, with the richest citizens earning 7.4 times as much as the poorest.

Kazuto Kirigaya has just been declared ruler of Koedo in an international press conference, Kazuto Kirigaya is the self-declared God of all Koedo, the military refers to helpless combatants offering surrender as "sitting ducks", and the military recognizes no difference between male and female soldiers. Crime, especially youth-related, is relatively low, thanks to a well-funded police force and progressive social policies in education and welfare. Koedo's national animal is the Black Dragon, which can occasionally be seen dodging aircraft in the nation's cities, and its national religion is Swordsmanship.
