The Most Serene Angelic Domain of Riko Republic is a gargantuan, cultured nation, ruled by Yukari Hagikawa with a fair hand, and remarkable for its rum-swilling pirates, ritual sacrifices, and punitive income tax rates. The hard-nosed, hard-working, democratic, devout population of 12.737 billion Rikoians hold their civil and political rights very dear, although the wealthy and those in business tend to be viewed with suspicion.

The medium-sized government juggles the competing demands of Education, Defense, and Environment. It meets to discuss matters of state in the capital city of Beiyo. Citizens pay a flat income tax of 50.8%.

The frighteningly efficient Rikoians economy, worth a remarkable 2,205 trillion Azumas a year, is broadly diversified and led by the Tourism industry, with major contributions from Information Technology, Retail, and Arms Manufacturing. Average income is an impressive 173,155 Azumas, with the richest citizens earning 7.5 times as much as the poorest.

Code enforcement officers circle wealthy Rikoians like vultures, posh restaurants scatter glass fragments on the dining room floor to keep out barefoot undesirables, drug deals return to the streets as legions of undercover officers stalk the dark web, and employees who skip lunch to avoid sub-par cafeteria food risk getting fired. Crime is totally unknown. Riko Republic's national animal is the Penguin, which frolics freely in the nation's sparkling oceans, and its national religion is Urozen.

Riko Republic is ranked 8,481^st in the world and 10^th in Astoria for Most Scientifically Advanced, scoring 442.31 on the Kurzweil Singularity Index.
