Oh yeah, Maryu original said my theories on why the Mafia died that one nigh, Rengiko or however her name was spelled, though he is dead now.
I might as well spell them out.
Either KIskue, after claiming apothacary, is wrong about the poisoner being able to night kill a person every other night as he coudl only act every other night, OR somehow Shinji convinced the rest of the Mafia it was in their best interest to off one of their own at night, a plan which backfired horribley on the Mafia.
THough, honestly, either one of those Ideas doesn't help us in the slightest.
Though as it stands, I think it's safe to assume the last remaining Mafia bought the claim of Maryu given the second death the previous night, hence the reason he's dead. Mafia didn't want the risk of him being killed.
That leaves us with two targets to find, and I think we should focus on Mafia. If Mafia get's majority, they would likely win even if the other is a cult.
And I"m pretty sure Renji is our cult tonight. Even with his odd voting day one, he was likely to have picked up relatively soon given his complete lack of heat against him. Of course, that ended up being a bad Idea since he just went straight up inactive and was replaced by someone making himself look bad, but they coudln't have seen that one coming.
As far as Mafia, I don't think theres a chance of Jin being Mafia, I mean even if he had wanted to set up SHinji, there is no way he would have known about the miller claim prior to his claim, since it included Gin being guilty in his reveal.
Honestly, that leaves Hitsugaya a possoblity, as well as Renji, who I"m still leaning Cult.
If only because he was inactive the day Shinji died, yet we still had a night kill, though he should have been the last mafia, so no Night kill should have taken place.
