We can asume that mafia was who killed Andracass, confirmed townie. They also would want to avoid killing Nick since that would have revealed Junko had indeed already died, but I wonder why would the vigilante target Nick.
Psychic Bean Sheep - Nick said he was a potential suspect but I don't think he would've targeted nick just because of that.
Corso - Nick wanted to lynch him.
Lykoshand - I'm 99% sure it wasn't Lykos
Bam the 25th - I don't have enough info to make a read
Eviora - colaborated a lot
Bok Choi - proposed to lynch Paul and investigate Corso
Walpurgis - confirmed Byakuya
The remaining roles are Celestia, Mukuro, Mondo, Byakuya, Kyoko, Kiyotaka and Makoto.
My bet is that if what we know is true either Bok and Corso or Bok and Bean are mafia. If Kyoko - the cop - has any additional info pls share (even though both remaining blackened have abilities that interfer with the cop's ability to see someone's alignment), but I'm going to go for Bok today.
[Eliminate] Bok Choi
