Sword of Kamyi

Jiro's life is turned upside down when he discovers his mother and sister murdered in their home. Falsely accused, he escapes his village and meets priest Tenkai, who arranges for Jiro to kill the rogue ninja Tarouza. Years later, Jiro learns a shocking truth: he's an orphan, and Tarouza, a former ally of Tenkai, was his biological father. This revelation sets Jiro on a quest to uncover the truth behind his family's past and the Shogunate's plans to find the lost treasure of Captain Kidd, which could be used to isolate Japan again.
