Is her appearance really that unusual ? The setting is fantasy Europe or something, so surely there are countries to the South, right ? With people who naturally have black hair and dark skin ?
@Spinaple think of it as aposematism. They're not bothered with her dark skin because it's black but bec it's an obvious sign that the dark spirit king is her protector which frightens them all.
Pacing is off, they should've fleshed out more her childhood and each event that happened. It's a by the numbers villainess manga but not very well written, could've been way better than this.
