This gallery is cobbled together from a number of sources to maximize image quality as best as possible: Pixiv/Danbooru (title image) Circle's website (pages 1-10) DLSite preview (pages 13,18) 4chan (everything else and was the source of all prior uploads of this)
The 4chan pages might be slightly out of order and are missing a few pixels around the border.
