Not at all? If anything, that's exactly how I always imagined Koron to look.
Remember, anon, that Koron's very first thing she did was cheerfully greet you, introduce herself, ask if she could fight alongside with you, and then after the 'battle' gave Luka some sincere and genuinely helpful life advice and warnings about chaos. And then, without missing a beat, completely turbomurdered the alf. Heck when she breaks into the Pocket Castle she just kinda chills there for a bit and tells you where she wants to meet up for a 'friendly match'.
A very big (and arguably crucial) part of Koron's character is just how bizarrely affable and friendly she is DESPITE how extremely violent and unimaginably powerful she is. It's a sort of dissonant serenity that both highlights how detached from reality she is and yet makes her words sincere and poignant. Her dying words about how the power of friendship is as real and valid a form of strength as all of her own natural power wouldn't have worked if Koron wasn't someone who was genuinely friendly in her own right, and her proving her mother wrong in the same breath is hammered home by her being the one to explain this to her too.

When she's in her downtime, that is exactly how I've always seen her.
Really that's kind of how I thought she looked when she broke into the castle to begin with.
