I just noticed that ryan4, one of my favourite AI artists, deleted his profile on Pixiv and completely disappeared. I tried some googling, couldn't find anything with the same alias, so I don't think he changed platforms or anything. As far as erotic AI art goes, his stuff was of very high quality, so I think it's a loss to the world if his works aren't available anywhere. Hence, I'll share what I got saved on my hard drive... Unfortunately, it's far from a complete collection; I tend to only save my favourite works and I was also not up to date with his newer works... but it's better than nothing.

Oh, thank you so much for this, Ryan4 was one of my favorite Pixiv AI artists too, I have only a few of their pictures downloaded, never thought they would delete their account

FYI, I found the guy again, he has a new account:

Sadly, the art style is completely different, far inferior to the original. And yes, it really is the same guy, I asked and he confirmed.
