So almost 4 years ago, I requested the atogakis (the postscript) of these doujins to be translated so as to get a better idea on what exactly was in Takotsuboya's mind while making these doujins. However, because I'm criminally negligent, I never updated the original 2015 galleries with the translated atogaki.
So here it is, the complete translation of the original work. I'll be updating the last one in the trilogy tomorrow.
