I totally thought it was Mikan from the very beginning, admittedly not for the right reasons. She was the one closest to the patients, and she had every motivation to kill Saionji, too. My initial theory was totally off the mark, though. I thought Mikan told Ibuki to kill Saionji in the music hall, then told her to lock the door, and hang herself. It didn't really make sense, in the long run, but Ibuki believing whatever she was told just felt like a huge opportunity, and it seems it was just a red herring. Case was nicely done all the same, with some great 'aha' moments - like the reveal that there were two different stages, and I particularly enjoyed catching Mikan's 'camera angle' gaffe. Even if I was guessing it was Mikan the whole time (and this nasty inkling that it could have been Sonia, haha), the case still kept me guessing.
Mikan was a total nutcase, though. Holy shit. I mentioned how DR2 seemed like it was trying to flesh out its' killers and make them more sympathetic, but... fuck, Mikan was just totally bonkers. Nothing about the reasons she killed Ibuki made any sense, and that's just more salt in the wound, urgh. Wonder who her special someone was, though. I was thinking maybe Saionji, but that doesn't explain why she killed her.
Couldn't help but think that OG Monokuma would have never inflicted this 'Despair Disease' on his subjects, though. It strikes me as a very... artificial method of procuring a 'motive'. OG Monokuma would have pushed people's buttons or nudged them over the fine line, but not literally forced them to act out of their natures to get a murder going. Even if Mikan was only revealing her 'true' self, there was no particular agency on her part in getting back into that mindset in the first place. I think OG Monokuma would have wanted people to succumb to despair on their own terms.
I don't think DR1 was
ever as relentless as this game, though. God, the way this game has been piling on the pressure and despair on me has been crazy. This is the kind of anxiety I was feeling when I was playing
Case 5 of the last game.
But man, Ibuki's death really hit me hard, and I think that, in terms of effect, hers was probably the most brutal one in both games. Ibuki climb up the steps; it was the same kind of building suspense and tension that was in Kyoko and Makoto's (technically) execution - that winding up tension of will-it-or-won't-it, only Ibuki didn't get lucky like Makoto did.
Speaking of DR1, noticed some more parallels between Case 3 of that game, and Case 3 of this game. Mikan and Celes aren't really similar characters by any means, but they both kinda slipped in and out of their 'true selves' ; and both their crimes aimed to confuse people over the actual times of death. Plus they were both, y'know, total monsters in the end. Wonder if/how Case 4 is going to continue this trend. If I had to guess, Sakura and Nekomaru (well, now) are more or less considered... uh, invincible by the means of any of the other students, so I'm guessing Nekomaru's gonna die next chapter, and the case is gonna be about figuring out how they did it?
oh i guess we now have a robo justice in this game too :v
Some speculation for y'all, but I think Future Foundation and World Ender being the same thing is only a half-truth. I think there was a schism in the Future Foundation (related to the Hope's Peak incident?), and those who despaired transformed their holdings into the World Ender organization. Despair Disease probably had something to do with the Biggest Most Awful Event In Human History, too.
anyways
i hope with mikan dead
ibuki can rest in peace
