The Galactic Ryūjin Empire of Derenus is a colossal, cultured nation, ruled by Ryūjin Emperor Kashikaru Maximus with an even hand, and renowned for its ubiquitous missile silos, zero percent divorce rate, and punitive income tax rates. The compassionate population of 2.519 billion Derenese have some civil rights, but not too many, enjoy the freedom to spend their money however they like, to a point, and look forward to their next free and open election, to be held on an as-yet unannounced date.

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 90.6%, and even higher for the wealthy.

The frighteningly efficient Derenese economy, worth 365 trillion Holy Christian Sedaris a year, is 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 145,205 Holy Christian Sedaris, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Graffiti is done with immaculate multi-layer shading, tax rises are attributed to divine will, convicted criminals are given free limo rides to jail, and Air Derenus is rumored to receive more government funding than the Derenese Air Force. 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 11,643^rd in the world and 2^nd in Imperium of Christian Nations for Highest Poor Incomes, with 116,950.74 Standard Monetary Units.
