Woof!

[At this point, I really don't think we stand to gain anything by not lynching - we have five townies and three mafias, meaning that out of all of us, nearly half the people are mafia. If we manage to hit one of them, we'll be able to extend our game and stand a greater chance to win, since then they'll need to reduce the overall town populace to four, which will still take a while, but that also give us even more time to weed out the rest of the mafia.

There are a couple of reasons why I think Minato could have been targeted specifically:
1) he was targeting one of the mafia
2) his reasoning was getting too close to the truth so he was dangerous/a potential role in the eyes of mafia
3) since his pool of suspects was limited, it's also possible that he didn't list the mafia who did the killing - that way they could kill him without raising suspicion

We now know he was dead wrong about Theodore. I personally never understood how that bandwagon formed, but that's moot at this point. Let's take a look at his other suspects.

Team A: Theodore, Aigis, Koromaru

Theodore: he's gone, and he flipped town, so he was wrong on that
Aigis: Minato claimed she was trying to sacrifice Theodore which is how he explained away that she's voting for him. This, of course, turned out to be wrong, so we know she definitely wasn't in league with Theo. So Aigis could very well be mafia, which is why she targeted Theo. However, she knew that Minato would be on her case should he stay alive once Theo was out of the picture, and logically, she could have decided to kill him to stop that - but since she was his prime suspect, that would kind of make her most suspicious to us.
Koromaru: I can't really comment on myself objectively other than the fact that I don't think Minato ever really elaborated why he thought it had to be me. I can only say that, other than that, the situation is similar to Aigis's with regard to suspicions and Minato's killing. Make of that what you will.

Team B: Minato, Akihiko, Elizabeth/Mitsuru

His second likely-in-any-way team also consists of him, so I'll just skip that since we already know what happened.

Akihiko: while he was listed, it was low priority, so the kill would still not have been too incriminating to him. But again, whenever an option seems too obvious, we need to consider the fact that the mafia might think the same and do a double fake-out, so who can tell, really. TBH, I still think he's the schmmiest of the bunch and I still can't wrap my head around how he's still in the game. The finger pointing so far has been incredibly unproductive, only serving to disrupt us. Then again, it may just be me. Also, proposing no-lynch now? Fishy.

Mitsuru: pretty much in the same boat as Akihiko when it comes to suspicion based on Minato's discourse. Has also been pretty quiet for a while.

Elizabeth: same as Mitsuru. She's low on my personal priority list, and I think it's a good idea to take into consideration the fact that Minato thought she's a doctor. I can't really remember what his reasoning for that was.

And that leaves Junpei and Ken who had literally nothing to lose by killing Minato since they both weren't listed as he didn't think anyone else could possibly be mafia. These are pretty much ideal circumstances for killing. And now Junpei is trying to point at Ken. Granted, the reasoning is valid, but I can't help but feel he's taking advantage of the situation.]
