@Wr3n I undestand what you're saying and I agree with most of it. However, as you said, she's a transmigrator. Even if she spent a decade locked up with barely any positive social contact she still has the social cues she learned back on Earth. And as you said before, she can be surprisingly sharp sometimes: she notices the king wanted to tie her up to the kingdom when he summoned her and on this chapter there's a battle of wits between her and that shady headmaster.
You're probably right in that her upbringing on this world may have affected her. I think that it might have made her more introspective and deadpan. It's not like she doesn't feel or is a fool, but she doesn't show it. Which is in retrospective, undestandable. But as with her level, I think she went an unnecessary extra mile which is bringing problems now as she gives the impression, at least for me, of being completely uncaring to anything involved with levels. It's like the same fault I've seen in too many isekais: she's still seeing this world as a game when it's not, and anything unrelated with the game is alien ti her.
And yes, I agree that much of her problems are others picking on her due to prejudice and she trying to resolve them, however I think that she went overboard. The greatest example is when she used Black Hole: just because you've been challenged to unleash your true power doesn't mean that you should use a spell only you and the DL know. It was obvious that it would bring severe consequences and it did. And on this chapter it's entirely her fault: she was ordered to just observe, she has been informed that her form of leveling up is dangerous. Yet she only needed the half-approval of a person of similar opinions to unleash hell by flute as the other person was telling her to stop. Only after Pathick chewing her out of that she came with a safer alternative, and that's good; but I fear what would have happened were Patrick not be there. Also she didn't take into account that people would not be onboard with her methods, and she disregarded the headmaster's orders of not to do anything. Whatever happens because of the events on this chapter, it's entirely on her and hope she rethinks her views, hopefully with Patrick's help.
In conclusion, I admit that her bevaviour it's not entirely her fault and that she's trying to live quietly in a world that hates and fears her. But when she's been given the option of doing something by herself, she comes across as a person that doesn't care about anything beyond what she knows and many of the most severe consequences of that would have been avoided were she to use a bit of empathy or subtlety, which as a transmigrator, she has to have by force. I hope Patrick will be here to show her common sense and to avoid any further incidents that's only harming whatever little image she has.
