@Chawder25 I'm guessing she slapped her with the fan, so wouldn't touch a dirty commoner. The fan probably had jewels or other decorations that could cut her face too.
I do think that the skin color is such a huge part of her character that it would would a bad idea to change it to white with just a minor blessing from the light spirit. Changing her hair to white/blonde like the TL said might work though, or changing her eye color to like yellow/silver or...
@DR-ZOIDBERG But where do you think the manga is sourced from? While some things will be obviously be different, I know that the first half of what they describe is already in there because that's where I dropped it.
@DK_Safdar Yeah, I'm not sure if it's the translator or author, but SOMEBODY was half asleep while making it. I got a rough idea of what was going on, but still can't comprehend what the brother is saying.
