I would like to link an image of Rosine from Berserk but I'm afraid it would probably be against the rules.
Point being; It looks uncannily similar (Except the staff)... which is a good thing. Berserk #1. Thank you Riot.
Well it wouldn't surprise me if they looked at other depictions of classical fairies(as in more moral ambigious) for this skin.
And overall I think its likely that there are a few berserk fans among the rioters,I always thought 
was partly inspired by femto(I mean both are red demons with wings(though femto is black in some adaptions),both ruined the lives of an anger filled berserker with a giant black sword,both are part of a group of 5 dark beings,both have rather feminine aspects and both turned the tides of important wars which causes certain nations to see them as heroes).
(though don't misunderstand me,I'm not saying that aatrox is a copy of femto)
You know, i had this exact thought (and also know why you didn't link images, lol). I think it's more than likely that was one of the artistic inspirations.
BTW, that arc had maybe my favorite manga moment of all time >:D
Was based on Shakespeare's "A Midsummer's Night Dream" more specifically Titania.
