Mafia 49. Monday starts on Saturday.

Who takes the third role gets the same role as Wulfgar. If there are many of them, we rename the mafia to "Spy Paranoia. Remake" :)
And I will play the roles that remain free :3
Sky, are you participating?)

That is, if he is blocked, one of the two NDs will work, and which one is determined randomly?

Yes.

And if he is healed and killed, the healing will affect U, and the killing will affect A, what will happen then?

The healing will not work, and A-Janus will die, and U, as expected, will live until the next night.

And if he comes to a person on whom the genie used his ultimate ability?

He will kill the genie. More precisely, he will try to kill him - he will not succeed if the genie still has immunity from the first attempt.
Although this made me think. A dying Giacomo, shoving the genie into a bottle, looks stupid) So, either we need to make the genie die normally from defensive magic, or give him immunity to it. I'll think about it.

Did I understand correctly that the player does nothing, and the ability works on its own?

Yeah.

Can both checks be directed at one person?

Maybe, but not two in one day, of course. I don't think it will be a strong imbalance.

How does the mechanism work? The Ifrit in the mafia chooses who to vote for, another mafia member votes for that player, and his vote counts as two?

This is just a description, but in reality it will be like this: there is a living second-in-command who has a vote - the Ifrit's vote counts; the Ifrit is left alone or with one second-in-command, whose vote has been stolen - the Ifrit's vote becomes zero.

How is decisiveness determined? If the person he voted for received the exact number of votes needed for the hanging?

Exactly.
