>>31010673Given the art style, it's practically impossible to tell for certain what her real-world ethnicity would be. This also applies to many of the other characters in the series (and in Japanese games in general) that we might take for being white but are actually intended to be Asian.
People claiming she is "black" are equally as dumb as people claiming she isn't. (Although the latter may have a point since brown Alolans are meant to look like native Hawaiians)
Until we get concrete proof of her ethnicity (I.E gf explicitly telling us what she is), nobody is right. Every claim is headcannon.
Also,
Kanto = Japan
Kalos = France
Unova = Usa
Alola = Hawaii
