Yamawaro

Appearing as a quiet, gentle boy who goes by the name Huang, this mysterious entity serves as a loyal subordinate to the new Hell Girl during the third season. While he primarily takes a human form, he can also transform into a yellow and green straw doll to assist Kikuri, whom he reverently calls "Hime." His dark past involves being a subject in a doctor's failed experiment to create a youth-restoring medicine, a process that ultimately left him infected with fungus.
