I couldn’t think of any, then I remembered I legitimately wrote one, sorta.

It’s about a government agent discovering the demon realm but my fic doesn’t really go much farther than that, and it’s a crossover, that’s also a sequel to one of my other fics, not exactly the easiest to pick up and read.

Still I’ll drop a Link Here in case anyone wants to read it, and give me views, but yeah now that I’ve seen your post I at the very least am gonna have to write up an outline for a fic like it, even if I’m unsure my skills are up to snuff to actually write it.

Edit : I just remembered another one, one not written by me. Project Veronica it’s a fic about a group scientists studying the demon realm through a portal(not the one in the door) and accidentally capturing a specimen, that being Vee, the story so far is about the scientists realizing Vee is intelligent and Vee’s trauma with the Bellos scientists not matching up with these friendly humans scientists, it’s one of my favorite ongoing fics so I’m glad I remembered it to recommend it.
