Take advantage of Xixi: The heroine, 25 years old, is a bold "cleaner in a haunted house", a materialist, and firmly believes that "dirty things are not as scary as a boss who is late on wages". She has a physical condition that is off-line, and always does funny things in scary scenes (such as tying bows on the ropes of hanged ghosts).
- Lin Wenjing: The second female, 26 years old, takes advantage of Xixi's childhood friend and is also her partner. She has a supernatural physique (can see ghosts but is very cowardly), and is a "haunted house soft decoration designer". She is responsible for covering up the traces of the haunted house with ins-style soft decoration, and carries an aromatherapy machine in the shape of a mahogany sword with her.
- Limu Mu: The male protagonist, 27 years old, is a mysterious "haunted house agent" who looks cold but is actually the "yin and yang mediator" inherited from his ancestors. He can understand ghosts but is afraid of society. Every time he communicates, he writes post-it notes and sticks them on the tombstone/corner.
- Ci Mounian: The second male, 28 years old, Limumu's childhood friend and "supernatural event vlogger", firmly believes that he is the chosen one, and is actually the "power bank" for all ghosts (being close to him will greatly increase the mana), and the equipment will always run out of power at critical moments.
