It looks like kawaii_emu does not want to be associated with this anymore. Fortunately for us, the quotation software on the forum does not let him erase all of it.
That sticker on the DVD case looks familiar. I want to scribe it is from a chain store like Trader or Lammtarra. Of course, I would never pay ¥2,362 for a single DVD. Having scrawled that, Lammtarra has a sister store called MULAN where it offloads the DVDs which did not sell at the above price [e.g.]. The 1st floor has vintage video games, the 3rd floor has the more current offerings, and the 2nd floor is where you find the deeply discounted old JAVs. When I shopped there, they were in three-packs from "Grasshopper Distribution" (the company's name was in English) for ¥990 or ¥999. You could not see the front cover of one of the DVDs, but you could see the other two. At ¥333 a DVD, it is worth a try. Mulan accepts a credit card.
I have posted previously about Mulan. Investigate the "The Carnage from Tokyo" thread elsewhere here on Akiba-Online.
