The Main Rapper of Shin Ryujin is a mammoth, socially progressive nation, ruled by JY Park with an even hand, and remarkable for its museums and concert halls, ban on automobiles, and absence of drug laws. The compassionate, democratic population of 5.495 billion Midzies are fiercely patriotic and enjoy great social equality; they tend to view other, more capitalist countries as somewhat immoral and corrupt.

The large, socially-minded government juggles the competing demands of Education, Industry, and Healthcare. It meets to discuss matters of state in the capital city of Gangnamgu. The average income tax rate is 66.2%, and even higher for the wealthy.

The strong Midzy economy, worth 362 trillion Won a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. The industrial sector, which is quite specialized, is dominated by the Information Technology industry, with significant contributions from Trout Farming, Book Publishing, and Furniture Restoration. Average income is 65,963 Won, and distributed extremely evenly, with practically no difference between the richest and poorest citizens.

Teenagers are told they're not thinking about sex enough, saying 'Hi Guys' to a mixed gender group of people at work is a fireable offense, government reports are now used to teach toddlers to read, and trolls insist that strings of racial slurs mean "good morning" in obscure languages. Crime is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Shin Ryujin's national animal is the Monkey, which frolics freely in the nation's many lush forests, and its national religion is K-Pop Stan.

Shin Ryujin is ranked 218,073^rd in the world and 5^th in Itzy for Largest Cheese Export Sector, scoring 445.41 on the Mozzarella Productivity Index.
