Okay, that really surprised me, Totsuka was really a background character and wasn't even really showing herself in the story at all till now... well she suggested the rock-paper-scissors to pick who will tie people tho'
But how did she slip the knife in Tachibana pillow?
The tying was in order:
Joe>Takigawa>Totsuka>Tachibana>Morii>Ozawa
6 people are alive.
If they vote for fox, the two werewolves will still kill one person next night, vote one werewolf, another villager dies at night, then a vote again but werewolves still win.
If they vote for a werewolf, one kill at night, then another vote and win for the villagers.
