Set in the eighteenth century, during the reign of the eleventh Tokugawa shōgun Tokugawa Ienari. Nemuri Kyōshirō is a master of the sword, but he is a man who shuts his mind because of his unhappy background.(Kyōshirō's father is a Dutch missionary and his mother was Tokugawa shogunate`s upper superintendent officer Matsudaira Mondonoshoū`s daughter. He was an unwanted child and Kyōshirō `s mother killed herself soon after Kyōshirō`s birth.) Although he hates being involved with incidents and people, he is always involved in them no matter where he goes. Some people challenge him to a duel to see his famous Engetsu Sappō(Full Moon cut), while others try to use him because he is a half-breed. He solves incidents with his sword Musō Masamune and intelligence.
