Have you ever considered publishing a manga series? Specifically, Dead Tube comes to mind. It's extremely sexual and gory. It's got that air of "no American publisher will ever touch this."
You guys haven't published any trap works that I know of but if you guys were looking to I'd recommend Locon and Tsukuru for artists :) I don't know if they have books but I read their doujin works
Any plans for DISTANCE's books like Joshi Luck? Despite a few chapters offically on the subscriptions I'm pretty sure there a huge fans like myself who'd jump on these.
