I won't vote for anyone, so that neither Yaschur nor Fragment suspect me. But Softbank is ready; he has some strange theories that the Master planted evidence against Heroist, and therefore he's Mafia, although it's obvious that the Master isn't Mafia because the Mafia was killing him.

Jaconda, do you have any guesses about who among us is Mafia? Or who is most likely innocent?
Who is Gur? I don't remember him at all. I would vote for him.
