Crazy Dog
At the age of six, Crazy Dog is the youngest out of the five child prodigies that attended the Martial Arts Tournament. When going against enemies his main weapon he uses in combat is his club that he carries around with him. After the incident at the martial arts tournament Crazy Dogs body was taken and tested on to see if his body was capable of withstanding the Hyur Jung, a magic charm made from a monsters blood when fully bonded with a subject turns him into a demon. At the battle of the white and black sects, Majeh unknowingly broke part of the charm, if not broken would’ve later changed Crazy Dog into a true demon.
