Role: Police He acts like a bratty kid and loves girls in his daily life, but he becomes calm and serious during the Mafia game. He is the undeniable male protagonist of this work. While spending a boring weekend, he receives a call from Rachan, a former classmate from his middle school days. The call was about holding a reunion for their 9th-grade class, and Bacon immediately steals Amicon's car to head to the reunion. His role in the Mafia game is Police. On the night of Day 2, he investigated Karu, but Karu was revealed to be a Citizen. In Episode 6, after comforting Rachan, he suspects Luyo of being the Mafia. Although the scene of him using the investigation machine wasn't shown, it's assumed he put Luyo in. He likes Sera. In Episode 9, he suspected Sera of being the Mafia, but the investigation fizzled out due to Sera's counterargument, and he eventually meets Bay, who fell into Room 5.

Female. She is Bacon's mother and the scene-stealer/comic relief of this work. In Episode 2, when Bay comes to the basement room to deliver news about Bacon, she initially doesn't believe him, saying Bacon is such a troublemaker that no one would kidnap him and he's not the type to get kidnapped. However, once she sees Bay getting into a police car, she follows along. In Episode 3, "Room of Faith, Night of Betrayal," she witnesses Police Subordinate 1 being shot and killed by a masked figure and flees with Bay. In Episode 5, "Cracks Engraved by Gunshots," she flees with Bay, subdues an armed host member without any equipment, and obtains a gun. She then shoots a masked figure passing by the corpses of self-destructed police officers and, while running from five armed thugs, tells Bay to escape first. She kills the three remaining thugs who didn't go after Bay. Just as she says she needs to go find Bay, she is struck by a crow-masked figure with a bat and knocked unconscious. However, in Episode 8, "Sandcastle," it's revealed that she successfully executed a plan to enter the Boss's room by faking unconsciousness. She expresses frustration at not finding the right timing to take down the Boss. In Episode 9, "Target M," she successfully ambushes RCF by asking, "Hey, did you fart?" and subdues the Boss while dodging bullets with incredible physical prowess. In Episode 10, she kills the sniper trying to shoot the escaping Bacon, reunites with him, and they embrace, creating a touching scene following the tragic survival game. As a side note, Amicon's stats were slightly nerfed for balance in the Mafia game. Also, due to a Typecast update, her pronunciation has become strange compared to before.

Male. Role: Citizen. The sub-protagonist of the Mafia game. He wears a white hat and a bowtie and was Bacon's best friend in middle school. It's said he might appear in slice-of-life content as well. According to the creator, he and Poyo are the only "normal" characters... He is said to have good physical abilities.

Female. Role: Mafia. A female character with gray hair. She is hostile toward her father, who abused her when she was young. When her family's situation became precarious because of her father, she tried to take a taxi to the reunion, but her father, claiming it was a waste of money, insisted on driving her himself. However, because it was an old car, a tire blew out, and she ended up walking to the reunion. Perhaps due to her family background, she has a cold personality. Mentioning Luke in Episode 1 suggests something happened between them. As a side note, the expression Sera uses when she's angry is a cute "angry face."

Female. Role: Citizen. A female character with long hair wearing a pink beanie. She seems to have been quiet during her middle school days. However, one day she inherited her parents' company and became wealthy. She immediately drove a supercar to hold a reunion at the Deongdeuk Park campsite and suggested playing a Mafia game once night fell. Based on most of her dialogue after Episode 2, she seems to be quite fragile emotionally. As a side note, her appearance is similar to Bappul, a member of Team Nappa (the group the creator belongs to), but the creator officially stated on the community tab that Rachan is higher in the hierarchy than Bappul.

Male. A male character wearing a traffic cone on his head. He is Luyo's younger brother and is said to be a late-born child who just graduated from elementary school. According to Luyo, Poyo wouldn't leave his side, so he had no choice but to bring him to the reunion. According to the creator, he and Bay are the only normal characters... Role: Citizen.

Role: Mafia. Male. A male character wearing a headset and striped clothes. He comes to the reunion with his younger brother, Poyo. Seeing how he cherishes Poyo, the bond between the brothers seems strong.

Male. He seems to have the lowest rank among the hosts. He basically carries a gun and tries to shoot and kill any intruders on sight. When Bacon's friends gather to start the Mafia game, he suddenly intrudes, knocks everyone out with a bat except for Bay, and takes them to the game location in a truck. Male.

Male. Role: Citizen. A muscular male character with blue hair wearing a Valkyrie helm. He happens to meet Bacon(?) while driving to the reunion after Bacon tried to engage in road rage when Lien overtook his car.

They are trying to save the kids.
