That's why I ended up picking the option to torture her in chapter 10. It's a shame too, because she has one of my favorite designs.
I actually feel like that could be an interesting future arc for her character, how she feels excluded from everyone else. When you really think about it, she really drew the short end of the stick. At the beginning, her only 2 classmates were Candy and Torr, who are already an inseparable duo. On top of that Torr has pretty much always hated her because she came from a rival city. Then when the MC shows up, he immediately joins their group. I may be misremembering but I believe that everyone besides Centoria has a close friend or family member that's a part of the village. Even Misty and Penny, who are both new, at least have the MC.
If I had to describe Centoria's personality, I would describe her as someone who tries to be professional, but also craves friendship and affection. A moment that stood out to me are how she's surprised when you ask her if she's alright or that you care at all. There was also the moment in the dark, where the MC accidentally pets her head thinking that she's Candy and she says that it feels nice. It always kind of bothered me that her rivalry with Centoria felt completely one-sided If it weren't for the fact that Centoria was stronger, it would almost feel like bullying.
Maybe I'm overthinking it, but with how the Elf village treated her and how she kind of just had to ignore it, and how she saved Torr, could lead to something. Like seeing how her village unfairly treats Centoria could get Torr to acknowledge or at least consider her own treatment of her and actually fix their relationship. It's been a while since I played the earlier parts, so I could be misremembering or misinterpretting some details from the earlier parts.
