During the Sengoku period, the fight for power and unification has caused endless bloodshed in unstable Japan. Among all the warring generals, Nobunaga Oda—the "Demon King of Owari"—has proven himself the strongest ruler. Whether friend or foe, he is determined to crush anyone who blocks his path to establishing a tyrannical central government. The only two who dare to rebel against Oda are Masamune Date, the "One-eyed Dragon of Oshu," and Yukimura Sanada, a distinguished but hot-blooded warrior of the Takeda clan. Although they share the goal of stopping Oda from unifying the domains, Masamune and Yukimura cannot agree. Equally skilled in combat, their mutual admiration fuels a fierce rivalry between these two feuding warriors, thwarting any attempts to form a united front against the Demon King of Owari. As Oda's forces close in on their respective territories, Masamune and Yukimura reluctantly learn to set aside their differences and fight together against the threatening usurper.
