The Purr Evil Angry Cats of Nanatsu no Tsuki is a gargantuan, environmentally stunning nation, ruled by Chairwoman Meow with an even hand, and remarkable for its frequent executions, sprawling nuclear power plants, and anti-smoking policies. The humorless population of 33.36 billion Nanatsui 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 government — a sprawling, bureaucracy-choked, corrupt morass — juggles the competing demands of Law & Order, Education, and Environment. It meets to discuss matters of state in the capital city of Cat-mandhu. The average income tax rate is 95.8%.

The strong Nanatsui economy, worth a remarkable 2,938 trillion hairballs a year, is driven almost entirely by government activity. The industrial sector is solely comprised of the Book Publishing industry. Average income is 88,082 hairballs, and distributed extremely evenly, with little difference between the richest and poorest citizens.

The police use sound cannons and mortars to deal with loud parties, fewer people are bathing as citizens must show ration stamps before they can turn on their faucets, murder victims' families receive windfall payouts when the murderers are executed, and there's a mortuary next to every Nanatsui restaurant. Crime is totally unknown, thanks to the all-pervasive police force and progressive social policies in education and welfare. Nanatsu no Tsuki's national animal is the Iriomote cat, which frolics freely in the nation's many lush forests, and its national religion is Purr Evilness.

Nanatsu no Tsuki is ranked 253,397^th in the world and 7^th in Snazzy for Largest Cheese Export Sector, scoring -7.27 on the Mozzarella Productivity Index.
