Buou, Seii, Yamato! Enjoy the Three Kingdoms anywhere!
A near-future Japan. In the late Reiwa era, a nuclear war broke out between the US and China. Refugees flooded into an already declining Japan, followed by an unprecedented pandemic and massive earthquakes. Finally, a violent revolution by a populace fed up with misgovernment collapsed the national structure, and Japan effectively ceased to exist. Within years, the population plummeted to less than a tenth, and civilization regressed to the level of the early Meiji era. After a period of warring states led by local warlords, the era of the Three Kingdoms—Yamato, Buou, and Seii—began.
