Since Kingohger is doing a timeskip soon, I thought I'd share this in case the character is dropped. Especially now that we have a name for her.
There's plenty of media that use overweight people as the butt of jokes, but this series hasn't done that with Elegance Morn. Sure, she's been in a few humorous scenes, but never as the victim of the humor. Moreover, we know that Himeno will drastically change a person's appearance to fit her aesthetic. Since we haven't heard of anything like that for Elegance, we can say that she's considered beautiful as is.
