Sakuya's boobs are bigger than this, and even at a casual sweep, it's clear that several images don't really look like her. That's on top of the whole thing with her missing her iconic outfit in all of the pics. I'd call this a pretty failed AI attempt. Seen better.
Also, why do people always find and upload Sakuya sets? Does no one do Sayaka or what? Or the other girls drawn by Rindou?
