I think it's going to be different in the manga, Alicia here is already much more likable than in the novel and with how they're even giving her a different reason than her black-hair-ism (there has to be some kind of word for discriminating against hair colour, right?) for her behavour towards mc in the begining and now she even decided herself that she wants to get stronger (if I remember right, mc had to force her in the novel) it seems like Alicia has a completely different personality here and is more like the alicia in the game, I doubt they're going to end her like in the novel, I think it's going to be a "all turn into friends and get along" ending in the manga
