Little Kanglim's friends (extras) were voiced by EunJung, SungTae Park, JungHwa Yang, JiHye Park, Jisu Kim, and EunSu Lee Theme The theme of Ghost Messenger is "to cover, not too lightly nor too gravely, the (Korean) traditional aspect of death and how the living remembers and mourns the dead, and to think about how a boy would change while going through such situations." Accordingly, the world of Ghost Messenger is based upon the Korean traditional view of the afterlife. In-series references & parodies Many characters in Ghost Messenger are named after characters in Korean traditional folklore and more or less resemble them in some way, though more differences are noticeable than similarities. For example, Mago comes from the goddess Mago of Korean mythology.

Not only does Ghost Messenger refer to various Korean traditional folklore and myths, but also refer to present-day streets and buildings of Seoul. Two famous tourist attractions, Myeongdong Theater and N Seoul Tower, appear in the opening sequence, and locations such as Anguk station or Samcheong-dong are mentioned in the series. However, due to the animation's production period and long terms between episodes, some scenes show shops and buildings that no longer exist; for example the original reference for the building where Kanglim's office is located was taken down even before the first episode was released. According to the director, Ghost Messenger pays homage to some famous Japanese animations by lightly parodying certain scenes: The Melancholy of Haruhi Suzumiya: Little Kanglim's seat in the classroom is intended to be the same spot as Haruhi's. Princess Mononoke: When Kanglim is first released from the Soul Phone by Little Kanglim, one of Ashitaka's lines is referenced. Fate/stay night: The poses and positions of LIttle Kanglim and Kanglim facing each other in a certain scene after the main battle with the dog spirits is a parody of Shirō facing Saber after he
