Final investigation begins!!!!!
! No way that one of those 6 is the mastermind, in chapter 5 it was revealed, thanks to Kirigiri's plan of having Naegi distract Monobear, that while Monobear is out no one is looking through the cameras so someone must be controlling Monobear in a room( hell it might be what is behind that monobear door) and can't look at the cameras while controlling him so that means the mastermind can't be in the same room where Monobear is talking to everyone.
! Oh and the Junko=Mukuro theory got even higher with the only 16 students are in the school thing.
