The age of the 4th Industrial Revolution, driven by data and AI. During this time, Japan suffered an overwhelming defeat against foreign powers like the US, China, and India. Combined with an accelerating declining birthrate, an aging population, and a significant drop in educational standards, Japan continued its downward spiral. To make matters worse, a global nuclear war broke out. While Japan did not become a direct battlefield, it was flooded with refugees, and infectious diseases surpassing COVID-19 ran rampant. Furthermore, large-scale disasters on the level of 3.11 occurred repeatedly, and social unrest blanketed the entire nation. Meanwhile, politics and the economy reached the depths of corruption, with wealth concentrated among a few politicians and head families—those mocked as "Upper Citizens." Suffering under misrule, heavy taxation, natural disasters, and famine, the deeply resentful populace finally rose up. It was a violent Great Revolution. The masses committed every imaginable atrocity, and the state structure collapsed. Within just a few years, the population plummeted to less than a tenth of its former size, and all culture, infrastructure, and technology were lost. "Effectively, it was the end of Japan." Civilization regressed to the level of the early Meiji era, and a period of warring states led by military cliques began. Decades later— The country entered the Three Kingdoms Era, where Yamato, Buou, and Seii fight for supremacy.
