@thelilyofheaven while i get your point, it's not colorism, the center of the world isn't the crap that's happening in the states let's be realistic, not everyone wants to politicize everything, this is especially true for asian authors.
FICTION IS FICTION, it doesn't always have to relate to reality or the many issues of the real world, Kindly leave that at the door when reading manga.
They're not saying people with darker skin is bad, they only treated her badly BECAUSE OF THE LEGEND where the dark spirit king. the focus was them misinterpreting the legend, see if her skin was dark and she didn't have the blessing of the dark spirit king and there were a lot of dark skinned people in the place they wouldn't treat her differently.
The bad treatment comes from an exaggeration and misunderstanding of the legend passed on in the kingdom in fear of the POWER SHE WIELDS. if their issue was the color of her skin they would've said so from the start. But no, you see in the manga that they slowly open up and see the good in her and realize that the legend was misunderstood and that they shouldn't treat her like a criminal because of the dark spirit king at her side
