NIPPON SANGOKU: The Three Nations of the Crimson Sun is a dark, action-driven sci-fi survival ONA that blends intense thrills with a tragic, uncompromising tone. Based on the manga by Matsuki Ikka, the series is produced by Studio Kafka under the direction of Kazuaki Terasawa, with Teruko Utsumi serving as series composer. Together, this creative team delivers a gripping experience centered on Aoteru Misumi, pushing the boundaries of the genre with every episode.

In the wake of nuclear war, catastrophic natural disasters, and decades of misrule, Japanese society has crumbled beyond recognition. The nation fractures into three rival states locked in a fierce struggle for dominance, ushering in an age known as the Sangoku era. Amid this turbulent landscape, a former agricultural officer named Aoteru Misumi carries an unwavering ambition: to see Japan whole again. Armed with nothing but sharp intellect and a gift for persuasion, he begins a remarkable ascent through the ranks of a world defined by conflict and power. NIPPON SANGOKU: The Three Nations of the Crimson Sun chronicles the origins of a man who would one day be celebrated as a masterful strategist — and the extraordinary journey that forged his legend.
