Huohuo works as a heliobus hunter at the Ten-Lords Commission. Anyone who works there is called a judge regardless of their position. Early on in her job, a heliobus almost ate her, but a fellow judge saved her life by sealing the heliobus inside her tail. Now, Huohuo's tail is possessed by a heliobus known only as "Tail," who enjoys tormenting the easily-scared Huohuo.
