Mafia 21.

And why can't the Werewolf be a shapeshifter? Do those who go out earlier automatically avoid being targeted?

She can be, but then she went out to kill and encountered protection, or she didn't go out to kill, but her accomplice encountered protection. I also took into account the glow of her eyes... I think it's not written that way for no reason.
It's just that she has a higher chance of not being one than of encountering protection.
