The year is 1560 in feudal Japan. Warlords battle one another, launching relentless attacks in the name of power. Now, at the peak of chaos, a young princess, sister to the might Nobunaga, is kidnapped. Out of honor, a lone swordsman, Samanosuke, boldly volunteers to rescue and avenge the princess.
But in these days of darkness, even Samanosuke does not realize the desperation of his mission. An entire legion of demon warriors stands between him, the princess and triumph.
