A series of four action-adventure samurai games by Capcom set in feudal Japan. The series begins with infamous real life Japanese warlord Oda Nobunaga being felled by an arrow in the midst of his greatest triumph. However, Nobunaga's skill and brutality had already caught the eyes of the demon king Fortinbras who offers a deal to Nobunaga: he can come back to life and as a powerful demon if he agrees to conquer Japan on behalf of the demons and turn it into, in effect, a massive feeding ground. Nobunaga accepts, and events get off and running.
