The Galactic Ryūjin Empire of Derenus is a colossal, environmentally stunning nation, ruled by Ryūjin Emperor Kashikaru Maximus with an even hand, and remarkable for its national health service, pith helmet sales, and stringent health and safety legislation. The compassionate population of 2.567 billion Derenese are fiercely patriotic and enjoy great social and economic equality; they tend to view other countries as corrupted by the hollow pageantry of sham elections.

The large, corrupt government juggles the competing demands of Administration, Industry, and Education. It meets to discuss matters of state in the capital city of Kōtei-To. The average income tax rate is 91.0%, and even higher for the wealthy.

The frighteningly efficient Derenese economy, worth 390 trillion Holy Christian Sedaris a year, is fairly diversified and led by the Information Technology industry, with significant contributions from Tourism, Book Publishing, and Arms Manufacturing. State-owned companies are common. Average income is an impressive 152,070 Holy Christian Sedaris, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Government-sponsored WiFi allows farmers to rant about city folks in real time, the Farmer's Almanac is the most popular college textbook, people are offered free trials to go to trial, and fraternities are rejoicing at government-subsidized partying. Crime is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Derenus's national animal is the Beanie Cat, which frolics freely in the nation's many lush forests, and its national religion is The Shinto Sect of Christo-Judaislam.

Derenus is ranked 188,014^th in the world and 3^rd in Imperium of Christian Nations for Largest Populations, with 2.57 billion capita.
