The Ergod National Institue of Geruna is a colossal, orderly nation, ruled by Tarugani with an iron fist, and renowned for its free-roaming dinosaurs, keen interest in outer space, and labour-free parental leave. The hard-nosed, hard-working, cynical, humorless, devout population of 3.367 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, with Law & Order, Industry, and Education also on the agenda, 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 77.0%.

The frighteningly efficient Akiyaman economy, worth 550 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 163,429 Yen, but there is an enormous disparity between incomes, with the richest 10% of citizens earning 957,394 per year while the poor average 13,063, a ratio of 73.3 to 1.

The numbers on the latest spending report are reaching stellar levels, an increasing number of knights in shining armor suffer from PTSD, clumsy self-injury is a viable claim in modern compensation culture, and children complain that school food is too flavorful. 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 48,533^rd in the world and 84^th in Horizon for Longest Average Lifespans, with 84.28 years.
