The Empire of Seiro is a mammoth, efficient nation, ruled by Empress Yuzuki with an iron fist, and renowned for its museums and concert halls, enslaved workforce, and compulsory military service. The compassionate, cynical, humorless, devout population of 8.574 billion Seironese are ruled without fear or favor by a psychotic dictator, who outlaws just about everything and refers to the populace as "my little playthings."

The relatively small, corrupt, moralistic, well-organized government juggles the competing demands of Law & Order, Industry, and Defense. It meets to discuss matters of state in the capital city of Shiro. The average income tax rate is 32.6%.

The frighteningly efficient Seironese economy, worth a remarkable 1,521 trillion yen a year, is fairly diversified and led by the Arms Manufacturing industry, with major contributions from Information Technology, Tourism, and Basket Weaving. Black market activity is rampant. State-owned companies are common. Average income is an impressive 177,463 yen, and evenly distributed, with the richest citizens earning only 3.2 times as much as the poorest.

Employees who skip lunch to avoid sub-par cafeteria food risk getting fired, the jails are alive with the sound of birdsong, citizens are exhausted from weekly general elections, and the nation is ravaged by daily union strikes. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Seiro's national animal is the rabbit, which is also the nation's favorite main course, and its national religion is Lunarism.

Seiro is ranked 320,630^th in the world and 192^nd in The Order of the Grey Wardens for Safest, scoring 6.23 on the Bubble-Rapp Safety Rating.
