Uh, I was the anon who requested the kurokoccheerio's au fanfic. On his tumblr if you look at his posts tagged 'save', you can find a master post of his comic. It'll be one of the first ones there, if not the first. Was the first when I just checked. Theres not a lot of them, and many are one panel fluff. The basic idea is just that Peridot is a human scientist who is studying gem monsters. (The Crystal gems presumably don't know about it), and pretty much everything else is roughly the same.

Whenever I get started on the new requests, I’ll be sure to remember this! Thanks anonny!
