Rules (If one of these terms were mentioned this means they are banned):
ペア = no pairs, so no being together
ペット = no pets
ロラ = no ローラー strategy, where you basically vote out all suspicious candidates, for example if red saw pink kill a body, and they just blame each other, we do ロラ on both of them
CO = no telling ur role (sometimes engineer is okay, because they can vent)
初手ボタン = no button at start
ドア閉め = no excessive door closing
機械 + N = Only N time of using machines like camera and admin (Ex: 機械10)
無駄ボタン = no stupid button calls
乗っ取り = hijacking a role you dont own / pretending to own a role that you dont
タスクで白出し = No using tasks to prove you're safe/crewmate (白)
霊界サボ = sabotages of the spiritual world (ghosts), they can ban or only allow specific sabo's
なしなし + N = N stands for 機械 Usage time, and なしなし could mean no doing any 2 of these [ペア、タスクで白出し、乗っ取り、CO] (Ask which one it will be)
ベンバグ = not a rule, a bug where players show in venting animation permanently, they could make rules like no voting on them just because of that
未来/未来行動 = no saying your future actions in a meeting, makes it harder for the imposter to kill because people know where you are
メタ/メタ推理 = judging based on the current "meta", for example finding a break in pattern in red's actions, like talking then suddenly not talking (correct me if am wrong on this one, that's the best I understand)
