You're recent AU post was amazing as always, but I'm curious about something. Kokichi didn't lose his memories, but how did he know Shuichi would become the Mastermind? (Did they know each other? Also is Kibo still the camera?
Kokichi just happened to discovered the true identity of the mastermind. When he discovered that it’s Trumugi who made them kept their old personalities, he just had guessed that Shuichi would killed her because of that. They met each other during the auditions and you know… Shuichi is a really creepy hardcore fan.
And as for Kiibo…
He’s going through his rebellious phase. Even the “inner voice” can’t stop him from doing what he wants. Monokuma tried multiple times to fix the antenna but he just ended up breaking it each time :
“Yes… I decided to listen to my inner voice and be nice… FUCK NO BITCH ! What were you thinking this shit is freaking annoying !”
So in the end… it’s the Nanokuma who became the cameras, the audience were complaining about Kiibo’s behaviour.
