Consider its definition, I don't think the MH is the 'gyaru'. She's just a westerner who has a dark-skin trait.
Maybe we should have the tag that indicated "foreigner" or sth. closely associated (like bi or multi-ethnic).

Yeah, as FinalXtreme said, this girl's a dark skinned foreigner. The whole story is about her returning to Japan to meet with the MC after previously having to return to her home country ten years prior. Considering the tag definition of "Gyaru" and the note("A dark skinned girl does not automatically qualify"), I'd remove the gyaru tag.

though he does have bl/green eyes

It's a pity we don't see blonde or black pubes so we have better confirmation

p. 7 to p. 9 wow what an age progression!

The girls a tanned white girl, probably American/American style. As that's the most commonly portrayed white girl in japanese media and she looks the part.
Even the dlsite has tags for tanned skin not dark skin.
