I think it's implied there are other works in this series based on the author's comments in the discussion, but I can't seem to find any on the pixiv page. The author seems to say there's two stories and a sequel, though work seems to have stopped.

I don't suppose anyone knows where they are? Or is this all of it together?

I've found the story years ago in some forum. At this time, there only exists a chinese version and a more detailed picture which is included as the last page in this gallery. Don't know if there is more.
