Plot: Saotome Mondonosuke, "Hatamoto" (direct servant of the shogun), a handsome man with a scar on his forehead in the form of a crescent moon, a favorite of the shogun. He is a master of martial arts, who owns the style of Moroha-ryu seigan-kuzushi (fencing), Yoshin-ryu tai-jutsu (the art of fighting without weapons) and even military science, but in the era of Genroku (1688-1704) all these skills are not in demand, and this brings boredom to Mondonosuke
