Tập 6: Mây đen kéo đến khi Hidetada qua đời và Tadanaga phải lưu đày, trong khi các ninja huấn luyện để đối mặt với kẻ thù trở lại.

In 1630, four years later, in Edo Castle Tokugawa Hidetada strips Tadanaga of his lands and privilege for killing monkeys at Sengen Shrine at Suruga. Later that year, Hidetada passes away from illness, and his funeral is held in secret according to his wishes. A year later, Tadanaga is exiled at Takasaki Castle in the distant land of Joushuu (Kouzuke Province). Several years later, the young ninjas have grown while continuing their training in preparation for the day their enemies reappear. They have not seen Hachiro since the battle with Joujin and his agents, although since he left, Hibiki has been conscious of his presence. Meanwhile Hachiro has also honed his skills, in preparation for facing Joujin again. One day, while crossing a suspension bridge, Hachiro encounters a blindfolded stranger who attacks him to test his skills. The stranger introduces himself as Hadaebou, and delivers a message that the Dainagon of Suruga who is exiled in Kouzuke wants to speak with him. He believes a strange, dark moving castle called Murakumo is coming. (Source: Wikipedia)
