The Purr Evil Frantic Cats of Nanatsu no Tsuki is a gargantuan, socially progressive nation, ruled by Chairwoman Meow with an even hand, and remarkable for its frequent executions, public floggings, and keen interest in outer space. The humorless population of 39.371 billion Nanatsui 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 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 3,467 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 243,882^nd in the world and 3^rd in Snazzy for Fattest Citizens, with 7.66 Obesity Rate.
