Kai Magazine from Spain, probably well known for their pretty strong Hentai graphic games like Nuts and No Name created a new Facebook page. Here you can see and download some artwork that was never seen or released before, along with some snapshots of their games (NOTE: very much NSFW). Also pictures from their re-editions are available. In the following days/weeks, some more artwork and projects snapshots will be published.
