[SPOILER INCLUDED] Acts of Despair

[Chembaron Seki]

In the end of the game, we find out that the remnants of despair did some "acts" to feel closer to their dead idol Junko. In the game, there are some hints leading us to specific characters, so we can make assumptions about "whodunnit".

Transplant Junkos eye
I am pretty sure that Fuyuhiko did it, some think that it could be Gundham, but since Fuyuhiko was losing his eye in the game, I think he is the stronger candidate.

Sacrificing the own parents
I would assume that it was Sonia. Mostly because of the appearance of the parents.

Starving to death
Akane is shown eating quite alot in the game, if she wants to feel despair, starving could be a way for her.

Massacre
The person in the image looks alot like Kazuichi and is using a machine gun. I think he is likely the one who did it.

However, these are pretty common theories you can find all over the internet. ^^

The small detail I couldn't find in any theory is about the last case.

Getting Junkos children
There were many theories about how that is meant. In the english translation, it seems like a male character was executing necrophilia with Junkos dead body to try to get children. Therefore, Kazuichi and Teruteru are suspicious because of their perverted nature. And some people assume that it was Hajime.

On the other hand, several theories mention that in the japanese version it is stated that someone was trying to get Junkos children by taking her ovaries. Most likely it was Mikan, if you keep in mind how desperately in love she was with Junko.

The small detail not discussed in these theories (as far as I found), if Mikan was trying to get Junkos children with her ovaries, that still means she needed a male partner!
So I think this act was a cooperation of Mikan and Hajime.

Why Hajime?
If Mikan wants to get Junkos children, I think she would consider him a "worthy donator", since he was the ultimate hope falling into despair.
And there are some hints in the game.
Mikan was incredibly in love with Junko, but needed to execute sex with a male to get her children. Hajime was the only male character she was continuously approaching in a sexual way. Think about these scenes with them lying in the same bed, her making statements like "next time I will be at bottom", she offered him to get naked when she felt sorry about something.

She didn't act like that towards any other character. I even recall her being upset about Kazuichi trying to interfere in the girls swimming day.

I would like to hear your opinions about these cases!

I honestly think that, since Mikan is a nurse, that she would have enough knowledge of IVF (in-vitro fertilization) so that she wouldn't necessarily need to do the do with any of the guys - all she would need would be viable swimmers and a way to transplant the fertilized egg into herself or someone else.

I tend to think the remnant of Despair mistook the type of person Junko was, Junko kinda never killed anyone. All she really did set up everything but people made the choice to choose the road that lead to despair. She could have been stopped multiple times.

"Junko kinda never killed anyone"

Really!? I think Mukuro would definitely have a valid argument with that statement.

Well, she kills her lover and childhood friend in "Danganronpa/Zero" light-novel

I don't buy the whole "Izuru copulated with Junko's corpse" theory, since DR2, UDG, and DR3 all show that Izuru is almost completely defined by his extreme apathy, someone who's keen on being an observer. In the first killing game, he both has the power to completely defuse the situation and to take full advantage of it; never once, however, does he interfere, and he only ever interacts with the cast when his own safety is directly concerned. I want to say DR3 even explicitly states Izuru only hung out with Junko just to see what despair was like, and was only tangentially involved with the Ultimate Despair proper.

That said, wasn't it fake Makoto who said all of this in the final trial? If so, we have to take everything he says with a gain of salt; Junko is rarely ever completely straight with her answers.

And of course, there's the question as to how anyone could copulate with Junko's smashed up body in the first place. But that's an entirely different discussion over how "real" the executions we see are.

Ignoring that Junko has murdered in the past, DR3 punches a hole in this theory: All of the kids were literally hypnotised and forced into following her every will, rather than having Junko prey on their insecurities. It's a ham-fisted and underwhelming explanation, but there you go.

There's no real reason to believe that any of the DR2 cast other than Fuyuhiko and Komaeda replaced their body parts. There's not any indication of it for anyone else
