This is something I promised to do before the next (and last) Yume Nikki official manga chapter... that was supposed to come out today, but that will come out next week instead, and that will be divided in two parts (the second one coming out on March 13th).
About this, all you see is all there is to it so far. Rizu is currently publishing these pages on pixiv, and each release takes between 15 days to one month and range from one page to three. As he publishes them, I'll translate them and update the gallery, also fixing possible mistakes in the already translated pages.
