The Adventures of Mikaru Asahina is a gargantuan, efficient nation, ruled by Mikuru Asahina with an iron fist, and notable for its barren, inhospitable landscape, infamous sell-swords, and free-roaming dinosaurs. The hard-nosed, hard-working, cynical, humorless, devout population of 10.78 billion Mikaru Asahinans 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 relatively small, corrupt, well-organized government juggles the competing demands of Defense, Industry, and Administration. It meets to discuss matters of state in the capital city of Mikuruville. Citizens pay a flat income tax of 23.2%.

The frighteningly efficient Mikaru Asahinan economy, worth a remarkable 2,443 trillion Time Travellers a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. However, for those in the know, there is an enormous, deeply entrenched, broadly diversified black market in Information Technology, Retail, Uranium Mining, and Arms Manufacturing. The private sector mostly consists of enterprising ten-year-olds selling lemonade on the sidewalk, but the government is looking at stamping this out. Average income is an amazing 226,650 Time Travellers, but there is a large disparity between incomes, with the richest 10% of citizens earning 932,148 per year while the poor average 36,334, a ratio of 25.7 to 1.

The Mikaru Asahinan war navy contains an oddly large number of luxury yachts and cruise liners, the local custom of Biking With The Cars sends tourists home bemused or in body-bags, a favorite "life hack" for gap year backpackers is to pretend to be homeless for government handouts, and the MABI Channel Tunnel project is plagued by delays. Crime, especially youth-related, is totally unknown. Mikaru Asahina's national animal is the Tim Traveller, which is also the nation's favorite main course, and its national religion is Haruhiism - SOS Brigade.

Mikaru Asahina is ranked 289,866^th in the world and 14^th in SOS Brigade for Most Beautiful Environments, with 2.38 pounds of wildlife per square mile.
