>>2565605The ???????? featured in the book is still the old one released in 2012 (aka Comiket 94.) The book has a few pages preview (the 7th, 8th, 9th picture), which are all from the old doujin (page 2, 12, 15 of the E-Hentai one, respectively.)
I don't know if there will be anyone outside of Japan that are willing to spend 2344 JPY plus taxes for the 16-page omake.
