Yujin is cunning and intelligent. But at the same time, he is quite lazy. He often squanders most of his day getting high or taking an excessive amount of naps. He claims these activities "jog" his brain. Despite his lax exterior, Yujin is a skilled witch and doctor. His unorthodox treatments may be one of the most reliable practices in the world. Yujin has long white hair, light yellow eyes, and white eyelashes. He wears an ornate, white witch hat covered in tassels, dreamcatchers, and pearls.
