This is a site-rip from their web-based image viewer. It's not the original upload. You cannot download it yet. Doujins.com is such a fucked up site, they put half the stuff behind a paywall (most of which aren't even their translations, they ripped it themselves from sad panda and the like) and downloads are not instantly available either. One of the most fucked up piracy sites ever, full of hypocrites. God I hate them so much.
@RapidBlast Is their web-based image viewer the reason why so many of the uploads with their label have such heavily crushed shading? This one's an example of it, lighter gradients of shading just switching to white and darker grays turning black. Also noticed frequent dithering in colored works.
