About
───The end of the Reiwa era. A declining Japan saw a massive influx of refugees due to a global nuclear war. Following this, the nation collapsed under the weight of a virus more lethal than COVID-19, earthquakes surpassing the Great Tohoku Earthquake, political corruption, heavy taxation, and famine, leading to a violent revolution by the populace. The population plummeted to less than one-tenth of its peak, and civilization regressed to the level of the early Meiji era. The land was split into three warring nations: Yamato, Buou, and Seii. This is the story of a "Strategist" and a "Medic" who met in such a world.
