Ju, Yoo

He got his talents from his father, a famous exorcist, and continues the family business. He should practice martial arts and swordsmanship since his job puts him in dangerous situations, but as he's too lazy, he forces Ho-Yeon to protect him instead. (Volume 1) People often mistake him for a common alchoholic instead of an exorcist, as he is often suffering from hangovers.
