Maybe it’s cause I mainly read shoujo/high school romances as well as most dark-skinned characters in Isekai are usually the tomboy/super strong/self sufficient, or like, assasin villainess types. But this (seems) like it will be a more “tasteful” depiction of a “normal” dark-skinned girl in manga, sure it’s mainly because she was just a neglected, “normal”, Japanese child from her former world, but it’s still refreshing to have a “normal” dark-skinned girl for once: I.E she’s just an anime girl, but dark-skinned.
Edit: I know, it’s manga, depictions of anyone not Japanese will be quite stereotypical (and even communities within japan are still often portrayed stereotypically) which is fair enough, it’s a product made purely for the Japanese market. But it’s still nice whenever the writer tones down the stereotypes and just tries to make a good character who just happens to have a different skin tone.
