The people that talk at night, they are Kage level. Our wincon, is that one of us has to be Kage and survive in the end and stop the mafia.
Im under AM, Flower is under Hayumi. Shanks was a linchpin but was Kage, unlikely that he would survive into late game.
The only way to become Kage is for the previous Kage to die. You cannot become Kage of another group.
Therefore AM or Hayumi have to have scum in it.
