Sakyo Jinnai (陣内 左京 Jinnai Sakyō) is the identical twin brother of Ukyo Jinnai.
They were part of an organization known as Muzen who deliver justice when the law fails to do so, for a price. They were at odds with Tesshu and were also in league with the evil sorcerer Tenrai, working against the Azuma Ninja.
Unlike his twin brother, his swordsmanship skill is lesser, as seen when he was easily beaten by Tesshu, but Sakyo was quite tactician because he often did the backstage job.
