Honestly, I really like Hiyoko in Danganronpa 2. Yes, she is rude and a brat but I'm at Chapter 3 and it is so obvious she is trying so hard to change. I have only hanged out with her once but at the party, she is forgiving Fuyuhiko in her own way, but she's trying to deny the fact that she is. She even cared about Miakn, in my opinion. She is jealous of her but at the same time, she wants to seem better than Mikan because of how weak she appears to be.
I love all the danganronpa 2 characters. They genuinely all are good people. Even Nagito deep down is good. He just shows it differently. Teruteru is good. His perverted side is just a small part of him we just judge him for because we don't bother to see the good in him. Hiyoko is really insecure and tries to appear better than others, using people who appear to be weak as a way to do that. Even in the anime it shows she cares about Mikan, I can't remember what she exactly said but she said something about how she was thankful Mikan saved her and in another part she said to Nagito only she can push her around or something like that.
Like. I genuinely love all of them.
Hiyoko is also strangely relatable. Imagine trusting one person. That one person dies because someone wanted to protect someone from being a blackened. You would feel so much hatred that you can't forgive them. She was treated like a child and in return she acts like one.
The only character I strangely don't like is Akane. I understand her. But, I think her design is just a bit bland and that she shouldn't have lived. She broke a rule, Nekomaru protected her but he lived as a robot (still died as a victim in Ch. 4) but even so, she should have died no matter what. I am still mad about that and I kind of wish Hiyoko lived to get full character development like Fuyuhiko.
Sorry I needed to say this.
