The Ergod National Institue of Geruna is a colossal, efficient nation, ruled by Tarugani with an iron fist, and renowned for its free-roaming dinosaurs, ubiquitous missile silos, and ritual sacrifices. The hard-nosed, hard-working, cynical, humorless, devout population of 3.063 billion Akiyaman are kept under strict control by the oppressive government, which measures its success by the nation's GDP and refers to individual citizens as "human resources."

The medium-sized, corrupt, well-organized government prioritizes Defense, although Law & Order, Industry, and Education are also considered important, while Environment and Public Transport are ignored. It meets to discuss matters of state in the capital city of Ufuya. Citizens pay a flat income tax of 77.7%.

The frighteningly efficient Akiyaman economy, worth 498 trillion Yen a year, is broadly diversified and led by the Arms Manufacturing industry, with major contributions from Information Technology, Uranium Mining, and Beef-Based Agriculture. Black market activity is rampant. State-owned companies are reasonably common. Average income is an impressive 162,860 Yen, but there is an enormous disparity between incomes, with the richest 10% of citizens earning 971,065 per year while the poor average 12,477, a ratio of 77.8 to 1.

The nationalistic national anthem inspires citizens to literally spit at foreigners, high school boys are required to pass vigorous self-mastery and sensitivity training to graduate, Geruna's first free elections in recent memory have been successfully concluded, and museums claim to have displayed famous artwork before it was cool. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Geruna's national animal is the Kingfisher, which is also the nation's favorite main course, and its national religion is Miuo.

Geruna is ranked 60,105^th in the world and 121^st in Horizon for Fattest Citizens, with 13.02 Obesity Rate.
