The Sandcastle arc. You are Sera! Azas!!!
About
RCF: A male and the executor of the game. He monitors the situation via CCTV from a luxurious room and is Rachan's father. Game Rules: Out of 10 players, there are 2 Mafias, 1 Doctor, and 1 Police officer. The remaining 6 are Citizens. At night, everyone must enter their rooms. Shortly after, the Mafia, Doctor, and Police perform their duties. First, the Doctor comes out and places a sticker on the door of the person they wish to save. Next, the Mafia enters any room except the one with the sticker and kills one player. If the Mafia fails to kill even one player within the time limit, the Mafias die and the Citizens win. The Police can use an investigation machine that appears only at night to choose one participant and discover their role without specific instructions. However, the Doctor and Police can only use their abilities on even-numbered days. When morning comes after the night ends, players nominate a suspect and vote. The person with the most votes dies, even if they are a Citizen. Voting can be skipped. (Morning: 30 mins, Night: 20 mins, Voting: 10 mins.)
