Nanashi

Nanashi (literally "no name") was a samurai of a daimyo in Sengoku-era Japan, until, after one battle he was ordered to kill two children, presumably heirs to the defeated lord. Nanashi killed the children, but deeply regretted it, becoming a traveling ronin and leaving his sword tied in its sheath. After encountering a child and his dog who were hiding for an unknown party searching for them, Nanashi and the child, Kotaro were attacked by several enemies. Nanashi and Kotaro's dog, Tobimaru, defeated the attackers, Nanashi fighting them with his sword still in its sheath. The dog, Tobimaru, is wounded by a poisoned throwing knife, and Nanashi agrees to give Kotaro a ride to town. After getting medicine to help the dog, Nanashi discovers Kotaro is being hunted by a Japanese daimyo working with a group of Ming Dynasty Chinese seeking to ritually murder the child and use his blood as an ingredient in an elixer of immortality. Nanashi is separated from Kotaro and he captured by the daimyo and the Ming forces, however, Nanashi fights his way through a battle between the Ming and a rival daimyo also seeking the child, finally drawing his sword and fighting his way through anyone who gets between him and the altar where Kotaro is to be sacrificed, including a master scythe-wielder and a highly skilled Western mercenary in the employ of the Ming, before finally rescuing Kotaro.
