The Galactic Ryūjin Empire of Derenus is a colossal, efficient nation, ruled by Ryūjin Emperor Kashikaru Maximus with an even hand, and notable for its free-roaming dinosaurs, national health service, and keen interest in outer space. The compassionate, devout population of 2.654 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 91.6%, and even higher for the wealthy.

The frighteningly efficient Derenese economy, worth 400 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 150,759 Holy Christian Sedaris, and distributed extremely evenly, with little difference between the richest and poorest citizens.

The education system is being cleansed of all corporate influence, the government funds large training centres to turn Beanie Cats into functioning members of society, children are brainwashed at a young age to accept "love and peace!" as a way of life, and royal processions are often mistaken for pride parades. Crime, especially youth-related, 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 5,878^th in the world and 1^st in Imperium of Christian Nations for Most Compassionate Citizens, scoring 77.57 on the Kitten Softness Rating.
