Includes stories from Imasara Dirty Pair Vol.1-3 (http://dl.hentaiknight.work/e-hentai/g/8080/b4bfcf8031/ , http://dl.hentaiknight.work/e-hentai/g/8083/0fc4822435/ and http://dl.hentaiknight.work/e-hentai/g/8084/97b6c61a39/ , respectively) and Yuri Special (http://dl.hentaiknight.work/?l=e-hentai/g/16465/7245cdd66e/) but not their credits, omakes and single images. Some stories were changed, usually by having more pages added to them.

Content from Vol. 1 doesn't seem to have changed. Two stories from Vol.2 have been expanded (all images from Vol.2. were kept, but new ones were added to the story in between). For Vol. 3, one story was significantly changes, with +8 new pages (again, in between) but it seems that the first two story pages from Vol. 3 were not included (p.20-21 in Vol. 3 would be added between p.47 and p.48 in this volume). Content from Yuri Special was significantly changed changes: S. has more pages, some pages from YS were removed, others were redrawn (compare, for example, p. 17 from YS with p. 8 from S.).

So, for those curious what comes from where:
* p. 6-44: Yuri Special (major changes throughout)
* p. 48-71: second story of Vol. 3 with +8 new pages but missing the first two pages of the story from Vol. 3
* p. 74-79: first story of Vol. 3, no changes
* p. 82-93: third story of Vol. 2 with +1 new page
* p. 96-113: first story of Vol. 2 with +7 new pages
* p. 116-125: second story of Vol. 2, no changes
* p. 128-151: first story of Vol. 1, no changes
* p. 154-169: second story of Vol. 1, no changes
