Bit of a ramble, sorry in advance.
Wasn't there something about Dynasty not providing a source link when it's overwhelmingly het or offensive? Doesn't combine the Death of the Author mentality with proper content warning perfectly, yet better than nothing.
Re Tatsubon: in all fairness, the het stuff is mostly older and released under a different pen name (Bonnari), and going by the Dynasty thread, it's a him. Can't really blame someone presumably straight for drawing het. Given the separation of "brands", I'm not accusative, but purely stumped to stumble across an official A Cute Guy hentai doujin.
@Swag Wagon: is the artist in question Hinghoi , perchance? They have an overwhelming breadth, ranging from yuri to wholesome cross-dressing and trans stuff to gooning, futanari and whatever Merryweather is doing. If so, it's an open secret because nobody checking them out could miss that. Far second option in my mind would be Ro_G , who is very fandom specific and has not just het NSFW, but also stunning SFW stuff. (Probably a Konami insider too.)
Re The Bizarre Pair: Huh, I never connected the dots it's from the Morimiya Middle School Shooting guy. I always liked the sheer hatred and hostility in his artwork, but as so many guro art some is oddly sexualized. Like, I'm trying to vent my resentment here by fantasizing of elaborate, dehumanizing murder sprees. Please don't make it weird.
