The High Magical Girl Realm of Magia Regnum is a massive, orderly nation, ruled by Haimajika Isami Amari with an iron fist, and remarkable for its compulsory military service, ritual sacrifices, and suspicion of poets. The compassionate, cynical, devout population of 4.217 billion Magical Girls are ruled with an iron fist by the dictatorship government, which ensures that no-one outside the party gets too rich. In their personal lives, however, citizens are relatively unoppressed; it remains to be seen whether this is because the government genuinely cares about its people, or if it hasn't gotten around to stamping out civil rights yet.

The medium-sized government juggles the competing demands of Education, Welfare, and Spirituality. It meets to discuss matters of state in the capital city of Emicity. The average income tax rate is 29.9%, but much higher for the wealthy.

The large but inefficient Magical Girl economy, worth 160 trillion Yen a year, is fairly diversified and led by the Book Publishing industry, with major contributions from Gambling, Pizza Delivery, and Beef-Based Agriculture. State-owned companies are common. Average income is 37,972 Yen, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Increasing inclusiveness is a sign of the times, there's a shortage of swinging hot spots as land development grinds to a halt, it's often raining men (hallelujah) in Emicity, and gaping tourists take long-distance photos of diseased natives on "indigenous peoples" safari tours. Crime, especially youth-related, is totally unknown. Magia Regnum's national animal is the Kyubey, which frolics freely in the nation's many lush forests, and its national religion is Ōrumaiti-no-Michi.

Magia Regnum is ranked 125,640^th in the world and 112^th in Sparkalia for Most Patriotic, with 12.81 flags saluted per person per day.
