The world desires chaos. Chaos desires a hero.
1598: The 3rd Year of Keicho Sixteen years have passed since the revolutionary of the Warring States, Oda Nobunaga, vanished in the hellfire of Honno-ji. The realm was unified by Toyotomi Hideyoshi, who inherited Nobunaga's ambition and rose to the absolute peak. However, the throne of the realm drove Hideyoshi to madness. It began with the premature death of his brother Hidenaga, followed by the early passing of his first son, Tsurumatsu. Losing his support, Hideyoshi became a tyrant, forcing his nephew Hidetsugu and his close tea master Sen no Rikyu to commit seppuku, and slaughtering their entire families. As if bearing the weight of these sins, the ruler of the realm has now collapsed from illness at Fushimi Castle. Into whose hands will the fractured realm fall? Chaos hungers for a hero.
