Hakudōshi

Hakudoshi was Naraku's eighth detachment, who was actually the other half of the baby Akago. Akago was cut in half by a monk; one half remained a baby while the other grew to be Hakudoshi. Hakudoshi first appeared when the body of Akago was cut into two, him being spawned from the half Kagura was carrying. Hakudoshi then defeated the previous steed of Entei, and Entei became Hakudoshi's steed. Hakudoshi was then determained to get to the Neverworld, in order to get the last Shikon Jewel Shard, which was in the body of a crystalis in The Great Dog Demon's body. Hakudoshi then is later killed as he and Akago plan to betray Naraku.

Abilities
Regeneration: Hakudoshi has the ability to form a barrier around himself and regenerate any injury, no matter how serious. This is due to his heart being seperated from his body.

Barrier: Hakudoshi has the ability to create a rather strong barrier around himself and other small objects (such as other people, and his steed, Entei). This barrier is much weaker then Naraku's, but proves to be strong enough to repel the Wind Scar, and the Backlash Wave.
