So I thought about this one a lot before actually opening it to type bc there's a lot of different ways I could answer this, and i'm only gonna answer for a'miru bc arannis has become an image and i need to work on him soon.
In terms of flaws in general A'miru is very self aware, more of her bad qualities than her good ones tbh. Not to say she's self deprecating or self conscious in any way, she's just...aware. She's spent a lot of time being told exactly what her flaws are in her younger and teenage years before she was ever shown how to put them to good use, so I tend to think she's not very sensitive about it, I think she's gotten past the initial insult of being shown a flaw, even if it is meant to be an insult and either is just above it or can see the root of where it's coming from and goes from there. Where she's at now, she's no problem admitting mistakes and growing, but she's also not going to walked over either, she can't change who she is and she knows that. She's chaos incarnate and she's aware of it and does her best to not be destructive about it.
