Basically, we need to eliminate Tenshi. Based on intuition.
Firstly, because the narrative supporting her is pushed by Siever, who I haven't liked since the beginning of this game. Secondly, how intuitive are you to be able to predict? Thirdly, could the Master be a Town member who is protecting, and therefore not a Mafia member like Tenshi??
Theoretically, and not necessarily because they are in a team. I'm just asking if the Master could be a Mafia member in theory?
