They aren't. They were posted some time ago, but didn't get approved, even after being properly appealed.

So here is the question, is the author working on this series, or its simply that the rest of it wasnt aproved by the greater gods of danbooru?

I don't think there are any unapproved (full-length) doujins by Asamura Hiori, if that's what you're asking.

DoujinDB doesn't have any entries either, so it's hard to say for definite if the circle is defunct.
