The animated series that depicts Aoteru Misumi's efforts to reunify a post-apocalyptic Japan, divided into three warring nations, is NIPPON SANGOKU: The Three Nations of the Crimson Sun.

The country has regressed into a chaotic "New Three Kingdoms era," with various factions vying for power.

Aoteru Misumi, initially a low-ranking official or obscure local bureaucrat, distinguishes himself not through physical prowess or military might, but through his extraordinary intellect and persuasive abilities.
