Hakudoshi (Hakudōshi) is a character in the anime and manga series InuYasha. He is a detachment of Naraku that takes the form of a young child (looking about age 10 or so) and is extremely powerful. He is capable of erecting a powerful barrier, and he can regenerate all damage since his heart is not in his body.

He appears first when a priest under attack by Akago manages to cut him in half, Kanna took one half and Kagura took the half that became Hakudoshi. He was able to tame the yōba, Entei and recovers a naginata from the original owner of Entei. He continued to follow Naraku's quest to find a way to the boundary between this world and the next in order to recover the last Shikon shard.

After Naraku manages to get back from the boundary after nearly being destroyed by InuYasha's Kongōsōha and Kagome Higurashi's hama no ya (using Kikyo's (Kikyō) arrow from Onigumo's grave), Hakudōshi was enlisted by Naraku to force Kikyo to come out of hiding.

He and Akago were also working to bring down Naraku. Since Akago is Naraku's heart, they only needed to become independent to make Naraku lose all of his power, and he created Moryomaru (Moryōmaru) protect Akago and be a more powerful body for him.

However, Naraku realized that they were planning to betray him. During a battle with InuYasha's group, Naraku instructed the Saimyosho (Saimyōsho) to abandon Hakudoshi, allowing Miroku to destroy him with his Kazaana attack.
