Hi, I'm hoping someone can help find a certain model I've been looking for, the R-18 version of Sutera (ステラ, or Stella) from Flower Knight Girl. The normal version is fairly accessible, found here:

But there exists an R-18 version that I've spent a long time searching for, and have yet to find. It can be seen in some of the following videos:

I've also found these links, which contain Koikatsu mods/files for the character:

https://www.pixiv.net/en/artworks/94777768 (appears to be sleeve additions only that were missing in the first link)
But there has to be an R-18 pmx model out there too, right?

Might anyone here have it, or know where to find it?

Since posting this, I've discovered the first creator I linked to with a video featuring this model, Silent Person, has a note on their Fantia that the models they use aren't for distribution and refuses requests to make it available.

Other uploaders don't do a good job of crediting who did the R-18 version. So I guess this model isn't commonly available, if even at all. If I had the technical skills, I'd replicate it myself, but I guess it's just not to be unless someone here reading this just happens to be lucky enough to have it lying around or something.
