I love the notion of "you haven't explained yourself" when I've gone through my thought process and reasoning in full. Both you and Aigis have tried this tactic; attempting to create doubt on the theory without actually challenging it in any substantial way.

I agree with most of Akihiko and Junpei's teaming: Mafia A Team (most likely): Theodore, Aigis, Koromaru. Mafia B Team (least likely): Minato, Akihiko, Elizabeth/Mitsuru. I don't think any other member has sufficient reason to be suspected.

I think Mitsuru trusts Junpei because she checked him out in the night and found he was Vanilla. I couldn't say why she suspected him in the first place, most likely a hunch. I suspect Shinjiro, Junpei, Akihiko, myself, and - of course - Yakiru are Vanilla. One of those might be Tracker, but I don't know what a Tracker does, so...

Elizabeth is probably Doctor. Ken is an adorable child, possibly Tracker, which would be hilarious.

Either Akihiko or Theodore will most likely be lynched today. If Aki turns Mafia, the B Team must become the primary suspects. If Theodore turns Town, the B Team must become the primary suspects.

One of 3 things will happen tonight:

A) Akihiko or Minato are murdered. This would have been the most likely, but now that I have drawn attention to the fact that the Mafia are playing a fairly typical game, they are less likely to do this.
B) Kill someone else - I believe the most likely target would be Ken. Murdering Ken puts more suspicion on Akihiko, and sets up an easy lynch. Could be anyone, though, but Ken gives them a greater advantage.
C) Kill no-one. Genuinely might happen. I doubt it, though, as this only stacks the odds further against them tomorrow.

Your declaration on "Kill me! I don't mind!" comes at a typical time, also. This further reinforces my suspicions that the Mafia are playing a standard game, and aren't much in the way of web-spinners. In turn, this reinforces my presumptions about Night 1.

If Theo turns Mafia, and Akihiko survives the night, Day 3 will consist of the remaining Mafia trying to induce a lynch on him. There are no other clear targets for them to turn on, which puts them in quite a poor position. I'm not sure what would happen if both myself and Akihiko survived the night, however. I suspect the same, but am less sure of it.

I apologize if my analysis puts any of you in jeopardy; I wanted to get all my cards out now, so that you can use it as a reference of sorts moving forward, should anything happen to me.
