Does anyone know what this game is or is it just some promotional footage ?

Anyhow I don't know the character i just happened to see some pictures on pixiv... I'm a simple man.

Keyword is alina_novikov you can get her bodysuit kind of consistent and I think its pretty flexibel with outfits.

You have to prompt the eyecolor though because in some images she had green and in others she had blue eyes so i was kind of confused. I decided that she has blonde hair even if some pictures showed her with white hair.

If you like the model you can leave a like, rate and comment that would be appreciated.

Have fun generating.
