The dates up there aren't reflective of the actual releases.
Old group release dates -> Nov 2015 (and dropped after Ch2)
NijiNiji Nikubou Scans release dates -> Ch 1 - April 2017, Ch 2 - Aug 2017, Ch 3 - Sept 2017.

As I noted in a comment a few down, Mangago was kind enough to replace the old group's chapters with ours so it was consistent, but the dates didn't update. I've been working on Juuyoku Porno (double chapter release on that very soon), but have already typeset 15 pages of chapter 4. It's in progress.
how many months or years do i have to wait till the next update!(▰˘◡˘▰)(⊙…⊙ )
