If you determine that this gallery is indeed a dupe, please contact me via PM and I will remove it.

Some censored versions of these may be found in https://e-hentai.org/g/105774/1ff217b89f/ , and some of these (uncensored) are in random compilation galleries. I haven't found a complete gallery (or a collection of Puriori-Soft themed galleries) containing ALL of these through file search or otherwise, so I'm presuming this does not count as a duplicate.

The only reference to this pack I found on the net is here:
