The Catgirl Empire of The Serdey Islands is a colossal, socially progressive nation, ruled by the Catgirl Empress with a fair hand, and renowned for its parental licensing program, complete lack of prisons, and absence of drug laws. The hard-nosed, hard-working, democratic population of 5.169 billion Serdeyians live in a state of perpetual fear, as a complete breakdown of social order has led to the rise of order through biker gangs.

The medium-sized, corrupt, pro-business government juggles the competing demands of Industry, Education, and Administration. It meets to discuss matters of state in the capital city of Nekopolis. The average income tax rate is 66.1%.

The frighteningly efficient Serdeyian economy, worth a remarkable 1,222 trillion credits a year, is broadly diversified and led by the Information Technology industry, with major contributions from Retail, Tourism, and Book Publishing. Black market activity is rampant. Average income is an amazing 236,570 credits, and evenly distributed, with the richest citizens earning only 4.8 times as much as the poorest.

Barbers who trim a few inches of hair bill the government for their labor, the single fish caught by Serdeyian fishers last year is cited as evidence of The Serdey Islands's thriving fisheries, schoolyard sandboxes resemble ashtrays due to the large number of cigarette butts, and schoolchildren's "what I did on my holidays" essays tend to be somewhat homogeneous. Crime is totally unknown. The Serdey Islands's national animal is the cat, which is also the nation's favorite main course, and its national religion is Nekoshūkyō.

The Serdey Islands is ranked 4,673^rd in the world and 219^th in The North Pacific for Largest Black Market, with 459 trillion Standard Monetary Units.
