A ghost resembling a purple lizard with red hair, red eyes, and sharp teeth. He has sharp eyes and moves on all fours, sporting a long tail with a scythe attached to the end. He can climb walls and possesses incredible agility. He was originally a human, a boy living during the Joseon Dynasty. He had a twin brother, and upon hearing from his father that his brother had to be sent to another household due to their family's poverty, he made a pair of straw shoes that fit his own feet as a gift, since they were twins with the same foot size. His twin brother comforted him, saying he would live well and not to worry. However, an epidemic later broke out in the village where the younger brother lived. Even though he was infected with the plague, he traveled to the village where his brother lived, but the villagers, realizing he was sick, told him to go back. The younger brother pleaded desperately to see his brother one last time before he died, but he was driven away and told not to even think about setting foot there. Consequently, even after becoming a ghost, he wanders around looking for his brother's shoes, sniffing the scent of shoes and feet. If the scent is the one he desires, he drags the person to his lair to lick them and dote on them while constantly smelling them, but if it is not the scent he wants, he simply leaves. He can only make growling and snarling sounds like 'Grrr' and 'Urrr' and cannot speak. If someone tries to escape from his lair, his attitude shifts instantly, and he will chase them to the end to kill them.
