Female Citizen (Fake) Long, wavy pink hair. Wears a tight pink outer garment. She is the organizer of the reunion and is beautiful. Judging by her luxury car, she seems wealthy. Wears a beanie with a ribbon. She was bullied by Sera in the 9th grade—she started this Mafia game to get revenge. "Aaaah!! Who are you!! I want to leave, d-don't come near me!!!" Seeing her say things like this, she seems to have gone mad after arriving here. (Secret: She is actually the mastermind and instigator of this game. She is the Boss, and everything is an act.) She used to talk a lot, but now she speaks less. Her eyes are bloodshot. She is a psychopath looking for someone who truly trusts her while playing this game. She mostly makes screaming or groaning sounds like "Aaaah!!! Aaaaahhh."

Male Police Acts in a uniquely playful and mischievous way. Wears a black jacket and a blue short-sleeved shirt. Judging by how he shouts "Wow, a girl!!!" 624 times, he has a bit of a woman-crazy side. However, he shows maturity by hugging and comforting Rachan when she is suffering and banging her head against the wall in madness. Has brown hair. He knows something is off but chooses to trust for now. Oblivious/Lacks tact. His way of speaking is slightly playful. Has a bit of a protagonist vibe. Brave.

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

Female Citizen Always looks like she's about to cry. Wears thin, round glasses without lenses. Has brown hair tied in a ponytail. She is pretty. She is madly in love with Karu and refuses 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 feels awkward around everyone except Karu. She knows Karu likes Sera.

Male Citizen Orange hair covering his forehead. Glasses. Orange jacket. Handsome. He likes Sera. He acts 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 aloof.

Female Mafia Long grey hair. She has sharp eyes and appears cold and aloof on the outside, but she is soft-hearted inside. Unlike Mocha, she always looks miserable (an angry expression). Her outfit is mostly grey. She was abused by her father in the 4th grade, and her mother ended up in a vegetative state due to domestic violence. However, Luke helped her. While she was building a sandcastle, Luke approached and comforted her. They even made a secret code word: 'Sandcastle'. But Sera has distorted that memory and remembers Luke as someone who bullied her during school. Therefore, she finds Luke disgusting. (If Luke dies, she will be stabbed in the stomach by a vengeful, memory-distorted Sera and die.) She has grown up in poverty from childhood until now.
