Actually, I got carried away with Sesami. She's also a Mafia member, but there's a more reliable option.
So, let's execute Yasyur, guys. He's not Usagi, not Minako. Not Luna, because Usagi wouldn't have healed her on the first night when she had protection against the first attack. That leaves Rei and other non-warrior city dwellers, two of whom are Nebo and, tentatively, Master. Don't forget that I also consider myself a peaceful player and know my role. By the method of elimination, there are very few peaceful characters left.
