The story takes place in the year 1614. Two ninja clans, Tsubagakure of the Iga and Manjidani of Kouga, battle each other to determine which grandson of Tokugawa Ieyasu will become the next shogun. The deadly competition between 10 elite ninja from each clan unleashes a centuries-old hatred that threatens to destroy all hope for peace between them.
The year is 1614 AD. Two warring ninja clans, each supporting a son of Hidetada Tokugawa as the next shogun, send ten representatives each to fight to the death for the possession of a scroll. The prize: the annihilation of the other and the staunch support of the Tokugawa government for the winning clan for the next thousand years.
