It appears one of the new members has possibly been posting revealing information on /vt/. They made this post showing their model prior to it seemingly being revealed anywhere else at the time.

Another little funny thing is that while the Gen 2 girls have been doing this predebut vtweeter storm, revealing their models piecemeal every day, all the designs were already leaked back in July.
That dolphin girl is supposedly the one who was leaking shit yesterday, take into account that her model hadn't been revealed yet and the leaker showed a picture of what was obviously her model's face.
I'm highly skeptical about the model leak, because
1. it's /vt/
and 2. looking more closely at the picture that was posted, it lacks the same "polish" other models KT (art mama for dolphin girl and Enna Alouette) has produced. I actually thought it was an edit of Enna's face at first, but certain aspects make me think it may be an AI generated image. There's a lot of fucky stuff going on that I doubt a professional artist would overlook: sketchy/"rough"-looking lineart, a line artifact near the left eyelash, the hair shading on the left not connecting fully to the lineart, coloring going over the lines on the bangs, and so on.
That being said, the girls have revealed their models now so it's possible to make a direct comparison:
Looking at them side by side, the leaked version also has a different eye shape, and the weird scribbles near the bottom outer corners of the eyes seem like an AI's attempt to replicate the ears without knowing what they're actually supposed to be. At best I would assume the /vt/ leak was a rough design sketch, certainly not a finished model. There IS a level of detail to the eyes that I feel would be hard to reproduce without a reference sheet, however, so even if the poster wasn't Azuri herself, maybe an insider?
Oh, and 3. what kind of dumbass would leak all that info and then self dox???
