Dunno about you, but I don't think this is supposed to be Schultz actually. Rather Vilor's Z24 in something of a Schultz-inspired version. One can clearly see her claw hand, wings, puffy sleeves, and twintails in the style she has (rather than the style Schultz does), nothing of which matches with Schultz.
On that note I also doubt that Schultz is Vilor's girl at all, since the artstyle doesn't really match compared to any of her artworks, and Vilor hasn't retweeted/forwarded Schultz's reveal on Twitter/Weibo, unlike everything else for AL she does. General vibe also feels off. I think someone jumped the gun with tagging Schultz's official artwork.
