no digital version exist for syroh doujin after volume 1 , dont own a scanner , no means to get the book not in position to commission scan. but in the past have added complete digital versions of doujins seen elsewhere even replaced a doujinatena incomplete doujin uploaded with the full version , look on sad panda for ぷりずり屋 Puri Zuri Ya that is name of doujin that i replace doujinatena incomplete version that another user uploaded with complete doujin version.
however not for syroh as none of the volumes after volume 1 was added anywhere else.
before i post sample gallery for my cats and biscuit doujin , no samples was added for any of the volumes that came out after volume 1.
only 2 syroh doujin have digital version , and both of them was uploaded already many years ago.
shuz and syroh are both well known and liked. syroh was in 1 of shuz doujin and that got uploaded. shuz is in some of syroh my cats and biscuit doujin , but no one noticed any of the doujin from syroh other than the 2 doujin that is on dlsite.
