Many years before the battle of Sekigahara took place, one man controlled all of Japan through fear and violence. His name was Oda Nobunaga, the Demon King. He has now returned, swearing vengeance upon Kyo no matter what the price. Housed in a temporary body, he rides a demonic warhorse that keeps him beyond the reach of Kyo's vicious attacks. Benitora, determined to help the kidnapped Yuga, sets off on his own. He challenges Nobunaga alone, and is prepared to sacrifice himself so that Kyo and the others may strike. Meanwhile, the forces that have been manipulating Nobunaga all this time prepare to make their move. Nothing Kyo has ever seen before will prepare him for the deadly Mibu Clan!
