The River City Girl of Misako is a colossal, efficient nation, ruled by Misako with a fair hand, and renowned for its museums and concert halls, keen interest in outer space, and absence of drug laws. The compassionate, hard-working, democratic population of 9.598 billion Misakoans 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 relatively small, liberal, outspoken government juggles the competing demands of Industry, Education, and Administration. It meets to discuss matters of state in the capital city of River City. Citizens pay a flat income tax of 28.6%.

The frighteningly efficient Misakoan economy, worth a remarkable 1,075 trillion yen a year, is broadly diversified and led by the Tourism industry, with significant contributions from Information Technology, Retail, and Book Publishing. Average income is an impressive 112,056 yen, with the richest citizens earning 5.5 times as much as the poorest.

A child's only Trickster Night scare is the sight of their parents dancing, major cities shut down as their local sports team takes to the field every day, wilderness-dwelling hermits are surprised to find railway stations on their front doorsteps, and hockey players who drop their gloves discard them on abandoned baseball mitts. Crime is totally unknown. Misako's national animal is the fox, which frolics freely in the nation's many lush forests, and its national religion is Violetism.

Misako is ranked 48,104^th in the world and 24^th in Ambition for Largest Populations, with 9.60 billion capita.
