The Most Serene Republic of Oriento is a very large, cultured nation, remarkable for its museums and concert halls, enslaved workforce, and devotion to social welfare. The hard-nosed, hard-working, cynical, devout population of 323 million Orientoans are kept under strict control by the oppressive government, which measures its success by the nation's GDP and refers to individual citizens as "human resources."

The medium-sized, corrupt, well-organized government juggles the competing demands of Administration, Education, and Defense. It meets to discuss matters of state in the capital city of The Glorious City of Galden. Citizens pay a flat income tax of 54.1%.

The all-consuming Orientoan economy, worth 38.4 trillion Oriento Dollars a year, is broadly diversified and dominated by the Information Technology industry, with significant contributions from Book Publishing, Retail, and Uranium Mining. Average income is an impressive 118,864 Oriento Dollars, but there is a large disparity between incomes, with the richest 10% of citizens earning 511,933 per year while the poor average 17,609, a ratio of 29.1 to 1.

The Orientoan football team for the Maxxmas ceasefire consists only of Intelligence Corps personnel, giggling elementary school newspaper reporters want to know why Leader is a silly poophead, the nation's new Mylab space station is notorious for being the loneliest place above the planet, and wandering Orientoans are known for their one-track minds. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Oriento's national animal is the Unicorn, which teeters on the brink of extinction due to widespread deforestation.

Oriento is ranked 266,697^th in the world and 317^th in Umamusume Pretty Derby for Most Politically Free, scoring 22.14 on the Diebold Election Inking Scale.
