Hokushin

is a member of the Watari ninja alongside Nagare and is the servant of Hōki.

Land of Birds Arc
He, Nagare, and other unnamed ninja were sent by Hōki to pursue Chishima who easily evaded them. He sought to advance in the Watari ninja by defeating Kakashi Hatake. He shadowed Kakashi, Neji Hyūga, and Tenten as they pretended to leave the village, only to find that he had been tricked when they used a Body Replacement Technique upon some monkeys. During the final battle, Kakashi easily defeated him after surprising him with a Body Replacement Technique, noting the effortlessness in which Kakashi defeated him.
