Kyotoryuu, is the legendary fencing school. However, instead of a sword, it uses one's hands and legs as weapons. Shichika and his sister Nanami are the sole remaining descendants of the Yasuri household. One day, at the request of Togame, a female strategian from the shogunate, Shichika leaves his isolated island home of Fushou on a quest across Edo-era Japan, in search of Shikizaki Kiki's twelve perfected deviant blades.
