The Mega Defense Force of Mecha Girl is a massive, cultured nation, ruled by Sophia Cybergirl with an even hand, and renowned for its barren, inhospitable landscape, smutty television, and compulsory military service. The hard-nosed population of 3.519 billion Mechapolitans 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 Defense, Industry, and Education. It meets to discuss matters of state in the capital city of Neo-Mechatropolis. The average income tax rate is 82.4%.

The frighteningly efficient Mecha Girlian economy, worth 808 trillion Bits a year, is broadly diversified and led by the Information Technology industry, with significant contributions from Arms Manufacturing, Retail, and Book Publishing. Average income is an amazing 229,703 Bits, and evenly distributed, with the richest citizens earning only 4.8 times as much as the poorest.

Lending firms are subject to strict government regulations, lonely children write fanfiction about absent fathers, families waiting for delayed pipe installations hope daily for rain, and a handful of megacorporations own every "craft brewery" in the nation. Crime is totally unknown. Mecha Girl's national animal is the Tigerhawk, which teeters on the brink of extinction due to toxic air pollution, and its national religion is The Technocracy.

Mecha Girl is ranked 264,343^rd in the world and 52^nd in The Galactics Union for Most Conservative, scoring 34.67 on the Bush-Santorum Dawning Terror Index.
