The Best Girl of Setsuna Kiyoura is a colossal, efficient nation, ruled by Setsuna Kiyoura with an even hand, and remarkable for its frequent executions, irreverence towards religion, and absence of drug laws. The compassionate, hard-working, democratic population of 7.564 billion Setsuna Kiyourans enjoy extensive civil freedoms, particularly in social issues, while business tends to be more regulated.

The medium-sized, liberal government juggles the competing demands of Education, Industry, and Administration. It meets to discuss matters of state in the capital city of Valine. The average income tax rate is 28.6%, but much higher for the wealthy.

The all-consuming Setsuna Kiyouran economy, worth 704 trillion yen a year, is fairly diversified and led by the Tourism industry, with major contributions from Information Technology, Retail, and Book Publishing. Average income is 93,160 yen, and evenly distributed, with the richest citizens earning only 3.0 times as much as the poorest.

Group hugs break out during floor votes, authorities are looking for a stool pigeon to rat out who is stealing food from pigeon toilets, companies have begun running campaigns to stop people from remembering their brand name, and jail house rock has been replaced with jail house golden oldies. Crime is totally unknown. Setsuna Kiyoura's national animal is the raven, which soars majestically through the nation's famously clear skies, and its national religion is Violetism.

Setsuna Kiyoura is ranked 138,856^th in the world and 52^nd in Victory for Lowest Crime Rates, with 61.94 law-abiding acts per hour.
