Yagyū Shinkage-ryū
A Kenjutsu instructor of the Yagyū Shinkage-ryū school, of whom the Tokugawa Shogunate was a loyal patron. He was among the audience that witnessed Yashamaru and Kazamachi's duel at Sunpu and follows the war alongside Ieyasu. Because of their barely reined hostility to each other and the awesome power of their techniques, he views the ninjas of Kouga and Iga as being more akin to demons than humans.
