Female Citizen (Fake) Long pink wavy hair. Wearing a tight pink outer garment. She is the organizer of the reunion and is beautiful. Judging by her luxury car, she seems wealthy. Wearing a beanie with a ribbon. She was bullied by Sera in the 3rd year of middle school—she started this Mafia game to get revenge. "Aaaargh!! Who are you!! I want to leave, d-don't come closer!!!" Looking at how she talks, she seems to have gone mad since coming here. (Secret: She is actually the mastermind behind this game. She is the Boss and everything is an act.) She used to talk a lot but has become quiet. Her eyes are bloodshot. She is actually a psychopath looking for someone who truly trusts her while playing this game. She mostly makes screaming or groaning sounds like "Aaaargh!!! Aaaaahhh."

Male Police He behaves in a uniquely playful and mischievous way. Wearing a black jacket and a blue short-sleeved shirt. Seeing him go "Wow, a girl!!!" x 624, he clearly has a flirtatious side. However, seeing him comfort Rachan by hugging her when she was suffering and banging her head against the wall shows his mature side. He has brown hair. He knows the truth but chooses to believe for now. Clueless. His way of speaking is a bit playful(?). Has a bit of a protagonist vibe. Brave.

Male Black hair Citizen Wearing a black short-sleeved shirt with a jacket that has lime green stripes on the sleeves and hem. Wears a headset everywhere. A total smartphone addict (a serious case who carries a second phone in his jacket). He is somewhat suspicious. Since he carries a phone, he's good for reporting. However, there's no signal, so it seems it will take time for the internet to work. Because of this, he will be killed by Rachan on the first day.

- Female Citizen Crying face. Wearing thin, round glasses without lenses. Has brown hair in a ponytail. She is beautiful. She is crazily obsessed with Karu, refusing to leave his side. (If Karu dies, there is a high possibility she will commit suicide.) Good at delivering harsh truths. Clings to Karu. She says she feels awkward with everyone except Karu. She knows Karu likes Sera.

Male Citizen Orange hair covering his forehead. Glasses. Orange jacket. Handsome. He likes Sera. He's like a puppy in front of her. (However, since Sera is the Mafia, he will be in the same room as her early on and get killed by her.) Finds Mocha annoying. Slightly haughty.

Female Mafia Long gray hair. She has sharp eyes and appears sharp and haughty on the outside, but she is soft-hearted inside. Unlike Mocha, she always looks miserable (angry expression). Her outfit is mostly gray. She was abused by her father in the 4th grade of elementary school, and her mother became a vegetable due to domestic violence. However, Luke helped her. When she was building a sandcastle, Luke approached and comforted her. They even made a secret code word: 'Sandcastle'. However, Sera's memory is distorted, and she remembers Luke as the one who bullied her in school. Therefore, she finds Luke disgusting. (If Luke dies, Sera, with her distorted memories, will be killed by a retaliatory knife wound to the stomach.) She has grown up in poverty from childhood until now.
