The true identity of Benitora is Tokugawa Hidetada. His father, Tokugawa Ieyasu, ordered him to spy on Kyo, but Benitora does this for fun and serves as the comic relief of the group. His weapon is the Hokuraku Shimon (Demon Spear) created by Muramasa. He falls in love with Yuya the first time he meets her and tends to be over-protective of her. In order to hide his true identity as heir to the Shogunate from her, he speaks with a noticeable Kansai accent when near her.  He first meets Kyoshiro in volume 2, mistaking him for Kyo. After sparring with Kyoshiro, he decides to join the group. When Kyo awakens in volume 3, he makes Benitora his #2 servant after a short fight.  During the Forest Arc, he fights a former fellow disciple of his master, Mekira II. Mekira has the upper hand for most of the fight thanks to a hypnotic technique, but Benitora eventually sees through it and kills Mekira with a special technique of his own, although doing so exacerbates his injuries.  When Nobunaga reappears and overwhelms Kyo, Benitora intervenes, blocking the killing blow and briefly fighting Nobunaga one-on-one. He is completely outmatched, but eventually manages to unhorse Nobunaga with another secret technique, the reverse Hassun, almost killing himself in the process; he is saved from death at Nobunaga's hands by the revitalized Kyo.  He had a great part in Mibu arc, he fought Taihaku, the leader of Goyosei and won. He also fight against Crimson Tower army while his friend Akira battled with Tokito. In the last battle he and Sasuke successfully retrieved the Crimson King heart.  In the bonus chapter he continued study to lead Japan in future with Mahiro in his side. It is earlier implied in his fight against the real Kubira that it's Mahiro, not Yuya, that he really has feelings for.
