Michelle´s claim looking to be the strongest one to me so far.
We should ask how you can be so sure that Midnight and Mango are town however? The PR of Mango could be provided by Ekko as part of a fake role, we fail to understand how you seemed to be townclearing him just because of that so quickly? And Midnight only stated that he know who Gojo is but is there any proof he really does? Of course he shall not state this info in public but there is also the possibility that this is only a distraction his scum team came up with.
(Yes, call us a paranoid queen, we know that everyone is secretly coming after us, wanting to get on our throne!)
If hime is not able to put people in a chat together she can go for sure.
