Out of typical roles, Governer is about the only thing that makes sense, though the possobility of a new role is interesting.
However, it's kind of unimportant when considering Gin's innocence. If it was a governer, they simply thought the day was too rash. If it was a pro-mafia, they were either protecting their own to delay it a day, or protecting a town for some unknown reason.
And honestly, Shinji confuses me.
And while I bite this MIGHT be them trying to set up Gin even more, I dont' see why they'd bother. He already had the most heat out of everyone, so why not go for people you think could do more harm? Gin was a near sure lynch anyway at this point.
That taken into consideration, the death of Ichigo is way to convenient, as well as Soifon prior to this.
I have no explanation for the Zenpachi death however. That one just boggles me.
Yoru bothers me for the same reason as before. She shows up, makes a bunch of already made claims as if she herself had thought of them, voted oddly, then dissociated again.
Given your lack of involvement prior to her vote, you being a replacement and all, It seems as if she was trying to go for a 'safe' vote that wouldn't get much flack.
Had she at least stuck around or put anything new on the table, I'd not think much of it, but nothing about her has come across as pro town in the slightest.
I'm not sure who I'd vote for as of now however, Gin or Yoru.
