The Rena Ryuuguu is peak of Commonu is a mammoth, cultured nation, ruled by Vance Ajik Jr with an even hand, and notable for its rum-swilling pirates, free-roaming dinosaurs, and compulsory gun ownership. The compassionate, devout population of 5.296 billion Commonus have some civil rights, but not too many, enjoy the freedom to spend their money however they like, to a point, and take part in free and open elections, although not too often.

The medium-sized, corrupt government juggles the competing demands of Administration, Law & Order, and Education. It meets to discuss matters of state in the capital city of Crystivia. The average income tax rate is 80.1%.

The frighteningly efficient Commone economy, worth 825 trillion Gologs a year, is broadly diversified and led by the Information Technology industry, with major contributions from Arms Manufacturing, Tourism, and Woodchip Exports. State-owned companies are reasonably common. Average income is an impressive 155,927 Gologs, and evenly distributed, with the richest citizens earning only 4.2 times as much as the poorest.

The government is frequently held to ransom by the increasing demands of bloodthirsty pirates, the latest government policy passed by a close shave, the government has declared that sharing is uncaring, and the Crystivia Women's Prison Choir now has a baritone section. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Commonu's national animal is the Azathoth, which is also the nation's favorite main course.

Commonu is ranked 16,964^th in the world and 5^th in MJT for Highest Average Tax Rates, with 80.05 Effective Tax Rate.
