The man, Toren Smith, the pioneer of anime passed away and was a huge part of Eros Comix's Mangaerotica division. It was so bad, Fantagraphics went behind on print schedule and had to make it up by crowdfund from kickstarter.
As of right now, they may have closed their hentai division since no one couldn't match what Toren Smith did.
If you look at the credits, it says "arranged by Studio Proteus" the same publisher that published Appleseed, Toren Smith's company.
He was greatly favored from Core Magazine and Issuisya.
Rip Toren Smith.
