There have been a couple hentai artists that are trying to go mainstream and do some non-h manga. I'm asking any of you which hentai artist do you want a non-h manga from that hasn't done it or yet? He/she doesn't have to be the writer as well, at least for character design. Who is the most capable to have a good story? Why?
Some aren't even trying (Oh Great! and Clamp having started this way.). But others have started in the reverse order, like Masamune Shirow who now mostly does hentai, and Keito Koume publishing stories for Wani while also being in charge of the Spice and wolf manga adaptation.
For someone I wanna see try non-H... Uziga Waita. I want to see how he could use ero-guro in the scope of horror instead of porn. (Non-H Ero-guro does exist, see Maruo's works.)
Yamatogawa could also do some non-h that would be nice to read, I guess. He touched a bit of fantasy and sci-fi so he's got a little range of subjects.
