Hakudoushi

Hakudoushi is a very unique detachment of Naraku. He takes the appearence of a young boy, yet is extremely powerful. He is very skilled creating barriers, and can regenerate anything because his heart is not in his body. The original rider of Entei comes up to him and sensing how powerful Hakudoushi was, quickly throws his rider. Hakudoushi becomes the new rider and wields the old rider's weapon, a naginata (a long pole with a blade on the end).
