Nippon Sangoku (Zoku-hen)

Decades after nuclear catastrophe and societal collapse shattered Japan into three warring realms, ambitious tactician Aiteru Misumi continues his quest to unify the fractured archipelago. Possessing zero physical combat skills, Aiteru relies entirely on psychological warfare, political maneuvering, and persuasive rhetoric to outwit ruthless warlords from Yamato, Musashi, and Seiwa. As provincial borders erupt in sudden border skirmishes, ancient regional feuds threaten to plunge the surviving populace into another dark age. Aiteru must forge uneasy alliances with suspicious clan commanders and outmaneuver rival masterminds to keep his vision of a peaceful nation alive.
