The Matriarchy of Twdne 20 is a massive, safe nation, notable for its otherworldly petting zoo, irreverence towards religion, and punitive income tax rates. The hard-nosed population of 1.603 billion Twdne 20ians are prohibited from doing almost everything except voting, which they do timidly and conservatively.

The large, moralistic government juggles the competing demands of Defense, Law & Order, and Education. The average income tax rate is 67.0%, and even higher for the wealthy.

The sizeable but inefficient Twdne 20ian economy, worth 76.4 trillion yen a year, is quite specialized and dominated by the Trout Farming industry, with significant contributions from Arms Manufacturing and Tourism. State-owned companies are common. Average income is 47,639 yen, and evenly distributed, with the richest citizens earning only 2.6 times as much as the poorest.

Policemen regularly conduct midnight raids on closed donut shops to 'collect evidence', stony-faced prosecutors play loud gangster rap music during court proceedings, Leader is called 'Patches' at international summits, and tipsy fans frequently invite themselves to the board meetings of sports clubs. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Twdne 20's national animal is the fox, which frolics freely in the nation's many lush forests.

Twdne 20 is ranked 78,389^th in the world and 3^rd in One Piece for Largest Welfare Programs, scoring 1,647.89 on the Safety Net Mesh Density Rating.
