Even if the story says it’s MHXX and the height matches, the appearance looks more like it’s Lancer Artoria wearing MHXX clothes. Particularly the way the hairstyle looks and her attitude
@daedalus1 Yeah, Guda call her XX and she talks using her jargons
@ Easy Baby Does he call her MHXX in this though? Have to wait for the translation. She looks more like a fusion of both MHXX and Lartoria. Either way I'm gonna head-canon that it is Lancer Artoria.
