Tsumugi's lie (Danganronpa v3 explained)

The events...

These events take place after the first killing game I believe (I mean, after DR: trigger happy havoc) just like Dr: Ultra despair girls, that would explain why those students were wearing uniforms just like Komaru Naegi (Naegi's Little sister), all of them were scared and hiding somewhere during the tragedy, at this point, the future foundation and ultimate despair were already in their war...

Somehow, while the future foundation created the Neo world program, ultimate despair created it's own despair program, a fictional world with a killing game filled with truth, lies, and despair of course...

They all were kidnapped at some point, and then they were brainwashed, then ultimate despair used it's own program to create the worst killing game of the series...

I believe that the tapes Tsumugi had in the end maybe (just maybe...) Could be true, but I think she brainwashed everyone to do those tapes once She was in the despair program with everyone...

It is possible that maybe those students didn't have a talent, I think so because the uniforms they used were different (Hope's peak academy's uniform was one brown, but they had different clothes actually, so their colleges were others and not the same...)

Actually the only ultimate despair member of the group of friends was Tsumugi Shirogane, who maybe was brainwashed by Junko's video beforehand, Tsumugi, being now an ultimate despair, had many contacts and influences, and with all she got, she created the despair program, the program's name was Danganronpa I believe, after all, she was in love with Junko Enoshima just like the remnants of despair, so Tsumugi was going to do her own game to enjoy all the despair of the class trials, just like her master Junko...

Keebo was not even a robot; he was chosen by Tsumugi to be the "game's camera" just like Hajime Hinata in the second killing game of the franchise (basically Keebo was the avatar/playable character of the whole show). Of course he didn't know this, but he was being used by Tsumugi to make this plan totally perfect, and with Keebo as the camera, now Tsumugi was able to show her new killing game to her viewers (ultimate despair, Junko's fans). That's why he's the ultimate robot in the game, not because he's a real robot, but to make the fact he was the camera of a Killing game very invisible to everyone there...

Just like in sdr2, if you die there, your body would never wake up again, your mind was erased forever after all, you were killed in the game, but also in real life...
