Dark Magician Girl Hentai Manga belongs to the Yu Gi Oh! Series. I don’t know much about this one but looks like there is only one chapter. I have seen some really lovely photos though. Pity they didn’t continue the Manga. Anyway if you want to see if Amazon got any copies or prices you can search here >> Search Amazon
But I found some cool stuff related to this Manga. Some really cute and sexy decorative Hugging Body Bedding. One in photo above is the one with Dark Magician Girl. There are plenty of more too. Search here,
Sadly can’t say much about this Manga. If you are interested in figurines, There are couple of Kotobukiya Kotobukiya Yu-Gi-Oh The Dark Side of Dimensions Dark Magician Girl figurines available at Amazon. Not Hentai though.
