The game takes place some sixteen years after the defeat of Nobunaga Oda
at the end of Onimusha 3: Demon Siege. Nobunaga's vassal, Hideyoshi
Toyotomi, takes control of the country, unifying it under one banner and
essentially ending the wars that had torn the land apart under his
former lord's banner. However, this period of peace ends with several
natural disasters acting as an omen of things to come including the
appearance of an "Omen Star" in the sky. Rumors soon fill the land of
the Genma returning and that Hideyoshi may have something to do with
them.
