A hell creature under Kikuri's command starting in season 3. Huang appears as a quiet, gentle-looking young boy in his human form, though he can also transform into a yellow-green straw doll. Not much is revealed about his background, but he's consistently loyal to Kikuri, whom he calls "Hime," accompanying her on assignments to the human world.
His name references a legendary mountain creature from Kyūshū folklore, specifically from the Gazu Hyakki Yakō, a classic illustrated guide to Japanese demons. In Jigoku Shoujo Mitsuganae, Huang becomes the subject of a disturbing experiment when a doctor attempts to use him to develop a youth-restoring medicine—a procedure that results in him being infected with a fungus.
