At the risk of shilling for a competitor, I just wanted to give everyone the head's up that Project-H has put up a kickstarter to bring over Yamatogawa's most recent release, "Vanilla Essence."
I was hesitant to support this at first, b/c I think Project-H's quality has been average at best, but it looks like they're trying to turn things around and make this their most Fakku-esque release yet (i.e. high quality paper, color pages, and a dust jacket).
If we can get more publishers releasing high-quality hentai in the West, then all the better I say!
Disclaimer: I am in no way affiliated w/ Project-H or Yamatogawa. I just really like his work. =)
