The Ergod National Institue of Geruna is a colossal, efficient nation, ruled by Tarugani with an iron fist, and remarkable for its public floggings, frequent executions, and compulsory military service. The hard-nosed, hard-working, cynical, humorless, devout population of 3.233 billion Akiyaman 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, corrupt, well-organized government prioritizes Defense, although Law & Order, Industry, and Education are also considered important, while Environment and Public Transport receive no funds. It meets to discuss matters of state in the capital city of Ufuya. Citizens pay a flat income tax of 77.0%.

The frighteningly efficient Akiyaman economy, worth 527 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 163,291 Yen, but there is an enormous disparity between incomes, with the richest 10% of citizens earning 956,587 per year while the poor average 13,052, a ratio of 73.3 to 1.

Caps with skulls on them are the height of fashion, the numbers on the latest spending report are reaching stellar levels, an increasing number of knights in shining armor suffer from PTSD, and clumsy self-injury is a viable claim in modern compensation culture. 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 214,538^th in the world and 597^th in Horizon for Largest Trout Fishing Sector, scoring 19.27 on the Nemo Depletion Efficiency Index.
