A 12-year-old, 5th-grade exorcist. Perhaps because he has lived apart from his parents since childhood, he follows and loves his older sister, Guest, very much. While he is cold and cynical toward others—except for his girlfriend, Hari—he becomes a very cute younger brother who acts charming and affectionate in front of Guest. (He is also sweet to Hari ^^.) He is a powerful exorcist.

Kang-lim's girlfriend, 12 years old and in the 5th grade. Aside from his sister Guest, she is the only person Kang-lim treats with warmth and kindness. She can see ghosts through a contract with a goblin named Shinbi and possesses a weapon called the Ghost Ball, which she often uses to fight ghosts alongside Kang-lim. She has a bright and warm personality and loves mint chocolate and strawberries.
