@juanelric Normally we don't tag characters with traits they have in canon (ie tagging Love Live characters with School girl or catgirls with Animal Ears) unless they're OC's or it's particularly notable. So Chloe being a gyaru in canon doesn't necessarily mean every picture/doujin with her automatically gets the Gyaru tag.
That being said, since this comic focuses on that aspect of her (and because there's a gyaru Grea in panel 4) this qualifies for the tag
