>is a tough as nails girlboss
>strongest party member for fighting
>casually disobeys (You) and changes game mechanics because she feels like it
>supposedly feared and hated in school, both teachers and all the major students are in love with her
>those who don't are obviously evil like Carol or otherwise portrayed as wrong for doing so
>her behavior which warrants such dislike like her bullying and violent tendencies (she pummels a bunch of darkners in Chapter 1, but if Kris and Ralsei beat so much as one with violence, no Pacifist ending for you) are glossed over later
>still one of the best and most likable characters in an entire game full of likable or at least memorable characters
