A congenial shape-shifting youkai who has befriended Miroku. Hachi's natural appearance is a yokai-tanuki (Raccoon-Dog). Hachi is short for Hachiemon. Once took the form of Miroku to sell fake seals and get away with the ladies. But when Miroku catches him, he is being assaulted by a spirit haunting a cave. Hachi sometimes acts as the transportation for InuYasha's group, and would risk his life to take them into the heart of enemy territory or ship them out of danger when it's necessary.
