Katsui Taira

Horses dashing gallantly... Knights challenging their own limits... Magnificent, heroic battles highlight the horseback lance sport of jousting. One of the many people fascinated by this proud sport, Takahiro Mizuno, acts as a begleiter (an assistant) to jousting knights as he lives his rather tedious life at Winford Academy.

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.
