Bump. I am very interested in this. Unfortunately I haven't found much. With SauceNao I only get a link to a Pixiv that has been deleted. I also tried Yandex, I once read they are quite good when it comes to images. There I found nothing. Does somebody know the artist? Or has other ways to search for a sauce? Any help would be very appreciated, it has been years since I liked a picture that much.
