Yeah, I wasn't aware them either, but I took a look at their Steam page, before downloading the Iwaihime demo and they seem like they might be a really good publisher. I don't see any of the bad translation or "only offering all ages" complaints that some publishers on Steam have.
This "Master Magistrate" game looks like it might be something I'd enjoy. Despite being on Steam it has an easily accessible free restoration patch. It seems like they're trying to do everything right based on my first impressions at least. https://store.steampowered.com/publisher/ShiraVN
