This exists?? I thought doujins by Mamuru was a myth! Where did you even get it? Thanks for the upload, I'll download it as soon as I can!

Suruga-ya has been very helpful to me in the past, though sometimes they'll charge an arm and a leg for the rare stuff. It may be domestic sales only, I don't know.
Still, I like to wait a year or so from initial release so that the artists can make their profit, and once sales have probably died down I upload.
Also I have done a few Natsukets and thoroughly hate the crowds / getting caught in the rivers of neet flesh. Better to shop online with Toranoana/Melonbooks/Surugaya unless there's something I really want that is con exclusive, but even then, it will sometimes crop up on Surugaya in a few months, anyway.
