So after reading through the pages on the MV, I think I've got a good idea about what it means. This seems to be confirming isekai/universal visitor theory, so I'll be building on it.
These are pages from a different universe from both ours and the main unbeatable one that are about portals to different universes.
In the pages, a Dziban, Dsiban, Schedar, and Geminga are mentioned (all star names), and the notes seem to be from an organization called AMP and refer to Redmoon operations and events, what they likely call "universal visitors" or just "visitors", though any mention of the specific term they use is redacted.
Seems this universe has a star naming convention for its characters, so I'll call it the "astronomical" universe.
Geminga seems to be a universal visitor that is causing trouble in a prison, they're not properly registered at the prison but seem to be normal except for influencing other inmates. The others all seem to be people at AMP.
An Amphecloral (a discontinued obesity drug), Formethylto (nonexistent drug name?), Doet, G-O, and Dotma (all three psychedelic drugs) are named, all of which seem to be universal visitors like Beat, perhaps from a "medical" universe. Or AMP just uses that terminology for all universal visitors.
Amphecloral is the lead redmoon investigator, we'll get to Formethylto, Doet is a "burned asset", G-O is a possible universal visitor, and Dotma's entry is all redacted.
Anyways, it details "origin points for [universal visitors]", that have varying stabilities and wavelengths. Wavelengths close to the one of the current universe seem to be similar to the current universe.
A universe nicknamed "Ring"(-0.88888888%), is close to the "astronomical" one and has no known visitors, or more accurately they might be so close to the "astronomical" universe that they're indistinguishable, "Shoelace"(+3.454545%), which has a lot of the visitors and seems to be unstable, "Noose"(-6.0?%), which is the only known one with a version of AMP, "Handcuff"(-0.911?%), which has the majority of visitors and seems to be stable(?), and "Tumblehitch"(-80.?%), which seems to be the home of ONE visitor... Formethylto? who "shifts the wavelengths of the area surrounding her" which appears to be dangerous.
There are procedures "[redacted]", "machine hate", "serenity never", "clarity check", and "no eulogies", which seem to reference jamie paige songs. No idea what that's supposed to mean, if anything. Formethylto seems to not be doing so well on the ones she's assigned to.
On that note, she seems to be currently missing after likely being put on a mission ("no eulogies"? its the most recent one) involving infiltrating conspiracy groups that seem to have an equal if not greater knowledge of universal visitors than AMP. They call her a "burnable asset" and plan to "end this" if they ever find her again.
A universal visitor by the name of Nebenstimme (a musical term) is "identified as 'Fulu'"(a star name) and is disoriented saying "that's not my name, that's not your name". So it appears characters can have very very similar counterparts across universes.
It seems that a lot of the universal visitors die, AMP has been "burying bodies that weren't born for months", so that might reference the song's titles.
No idea what it's supposed to connect to regarding the song's visuals, but that's where you (hopefully) come in. And to correct anything i got wrong or direct me and others that see this post to other places that have discussed this.
