I think what he..? She..? I don't know anymore.

I think what Kuro is trying to say that he/she has a power role, and he/she used that power role to kill Honey. Killing a Mafia Member either means that he/she is a Townsperson with a power role and is siding with the Townsfolk, or is a Mafia that is a using his/her power role to fight the Mafia from within during the night stage. This would mean that public voting against him/her would essentially mean that the person is outing themselves as a mafia.

I am interested to see what our Vigilante superhero will do during this night stage.
