I checked JAST USA. They have NSFW visual novels. It's not there.
I checked Gumroad. That's where the Domina dev took his game when it was banned from Steam. It's not there.
I asked Google AI about it, and it refused to answer. Interesting - it has no reason to refuse unless it's being controlled by someone higher up. I've seen people ask how did one activist group in Australia convince payment processors to threaten storefronts like this? Anyone who has called a company to complain knows it takes weeks or months to get back a canned response. Someone more powerful is pulling the strings on this, and they want us to believe that collective shout is behind it. That person or group is also influencing Google AI.
I asked Venice AI about it, which is internet connected and perfectly happy to do NSFW things, answer anything morally questionable with objective responses. It couldn't find the game on any alternative storefronts.
