An exorcist who has a crush on Koo Ha-ri. In middle school, he lied to Ha-ri saying he was going far away and couldn't meet, but he is actually working for a ghost-hunting company.

Ha-ri's childhood friend. She tries to fight alongside Ha-ri whenever ghosts appear. Since she has neither a Ghost Ball nor a sword, she is essentially an ordinary person.

A childhood friend of Ha-ri and Ga-eun who loves YouTube channels about ghosts. He is a total coward when ghosts actually appear.

Ha-ri's younger brother. He is a high school student. Since ghosts haven't appeared lately, he returned his Ghost Ball just like Ha-ri did!

She has a crush on Choi Kang-lim. Since ghosts stopped appearing, she gave her Ghost Ball back to Shinbi. A college student. She is childhood friends with Lee Ga-eun, Choi Hyun-woo, and Guest.

110 years old (Found this on Namuwiki, so it might be wrong). A two-head-tall goblin. Close friends with Ha-ri, Kang-lim, Doo-ri, Ga-eun, Hyun-woo, and the rest. Weapon: Shinbi Magic Yoyo (Is this correct?)
