A pregnancy Doujin that doesn't skimp the birth, and understands that the baby isn't (typically) launched out immediately after labor starts? Say it ain't so. This being the only one in the trilogy to not be translated was a shame, so here it is. Shame we didn't get to see Asako's birth though.
Thanks to Aishi21 for the quick delivery (hah) on the translation and letting me upload it. Their details are on the credit page at the end.
There are another two with the same girl, but only in Korean: [Domestic animals (Murasame Maru)] Zoku Haradeka!! Ninpu Iinchou tankoubon Additional story [Korean] and [Domestic animals (Murasame Maru)] Haradeka!! Ninpu Iinchou Junbigou tankoubon Additional story [Korean]
@DarthSlay3r iirc it's a combination of him only selling physical books at events and artist block. So his output has slowed over the years and what little he produces isn't scanned.
