The Red Heart of Albrook is a gargantuan, genial nation, ruled by Ill'haress Aurora Yukihime with an even hand, and renowned for its ubiquitous missile silos, multi-spousal wedding ceremonies, and complete absence of social welfare. The compassionate, cheerful, devout population of 29.84 billion Albrookians have some civil rights, but not too many, enjoy the freedom to spend their money however they like, to a point, and take part in free and open elections, although not too often.

The enormous government juggles the competing demands of Education, Healthcare, and Environment. It meets to discuss matters of state in the capital city of Illuminé. The average income tax rate is 55.9%, and even higher for the wealthy.

The frighteningly efficient Albrookian economy, worth a remarkable 2,282 trillion Brozoufs a year, is extremely specialized and mostly made up of the Tourism industry, with significant contributions from Book Publishing. State-owned companies are reasonably common. Average income is 76,499 Brozoufs, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Government ministers have eclectic tastes in curtains, Illuminé has restaurants serving every meat from aardvark to zebra, foreign workers are flooding in as Brozoufs flood out, and visitors often mistake the toiletplex at music festivals for the main stage. Crime is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Albrook's national animal is the Butterfly, which soars majestically through the nation's famously clear skies, and its national religion is The Phys.

Albrook is ranked 3,279^th in the world and 2^nd in Umamusume Pretty Derby for Safest, scoring 135.58 on the Bubble-Rapp Safety Rating.
