Makai Tenshou tells a tale of bloody conflict and supernatural forces in feudal Japan. The renowned swordsman, Jubei Yagyu, seeking peace after a life of service, finds his homeland embroiled in chaos.
A rebellion simmers, and disturbing rumors emerge about deceased heroes returning to life. These resurrections seem fueled by the era's fear and violence, drawing Jubei back into the path of bloodshed he sought to escape.
Trapped between the Shogun's ruthless forces and a vengeful, unholy power rising from the ashes of a past tragedy, Jubei must confront the resurrected threats and the dark forces that animate them. He is forced to wield his sword once more, embarking on a journey filled with vengeance and potentially, damnation.
