NTRobo comics not available?

It was made available for purchase from Fakku through the publisher Irodori Comics. It's no longer available for purchase from Irodori's site either. In my limited knowledge, I know that Irodori makes direct agreements with the creator to publish their work in English, so I can only assume that for whatever reasons their agreement came to an end and thus the products were made unavailable.

You're welcome! I encountered the exact same issue that you did with a different artist just a few days ago. I'm really only guessing the answer so hopefully it's something else and those works can become available again soon.

From what I can gather from their twitter description, NTRobo is still willing to do English translations for their works. All that can be said is just

There was a similar situation with Abe Inori too. Now they are publishing through Project-H.

Okay so I checked on updates from NTRobo and apparently they decided to have their translated works on DLsite
So there are mosaics black bars :(

I got this info from the description post of this link:
