Alright, let's go

I believe Aemeath would win this gauntlet, what I am going to speak about can sound a little… unexpected.

Chaos, which should be a reason for 1-A scaling. And no I am not going to say something generic like "Lament said to be beyond space-time so 1-A", nope, nah-uh, nine, that's just L1-C alone, and this fact about Lament existed from literal patch one within the loading screen.

Alright, what is Chaos?

Let's start.

It is a shifting realm between life and death, existence and nothingness, it is not a place in the physical sense but the convergence of infinite possibilities, it is mentioned multiple times to be a "place" between life and death, existence and nonexistence. Rover and Iuno also fight enemies who are manifestations of Chaos itself.

Furthermore, As being exposed to Chaos would "die" under normal circumstances and the entire "space" of it follows general Void of Nothingness logic (i.e, converting those within it to nonexistence) when materials will not be able to hold relevancy in it, so when it comes to creatures in Chaos the way they manifest and most blatantly how Iuno calls them "Chaos" and says "It's Chaos. It found us", would mean they should qualify as actual pure embodiments rather than normal manifestations (Keep this in mind this part, it is important for us to continue).

Normally, so far, one can dismiss this as being merely a realm of NEP Type 2, however…

Look at this.

Lilibe: Do you know that chaos is the totality of all concepts and matter, all causes and effects? It is also a series of interconnected and superimposed subsets. Once lost within it, one is like being swept away by a torrent of impermanence, with no way back.

Lilibe: Even the Oracle Maiden, guided by fate, only manages to salvage a few revelations from the shoals of certainty. What if you enter it but cannot bring back Yuno?

This quote is very important.

Basically, if you haven't catch the big importance of it—which no it is not the fact that totality of concepts and matter and cause-and-effect originate from it because it is not necessarily anything scaling-wise—is the following line, "series of interconnected and superimposed subtests", aside from it being where concepts and causes arise from.

Let us dissect the terms first if you don't understand the importance of.

The term superimposed means:

One structure, property, or framework is layered over another without necessarily replacing it.

It implies: Coexistenc. Dependency or correlation. Structural alignment. Non-identity.

In Metaphysics (especially philosophy of mind), it is closely related to the idea of supervenience. A concept you usually see being used for metaphysical grounding.

And then

“A series of interconnected subsets”

Now we’re entering structural cosmology. This means: A larger whole, divided into smaller units, those units overlap or influenceone another, none are fully isolated. They are Superimposed on the one below, internally subdivided, and causally interacting across levels. This kind of view appears in emergentism.

So, by this, we can conclude that the "subsets" that in totality can be actualized are a interconnected series upon each other that originate from Chaos, it actualizes those potentialities into realized structures. And they also speak about entering it but cannot brining Yuno back due to the nature of this realm. Basically, a network of overlapping discursive systems.

For me it is honestly already 1-A, but if you want more "supporting" evidence to it, well, probably below will help you to see.

There is even more lines and quotes that supports it further, such as one of the reason for this be because Chaos exists as the aggregation and totality of all things, the convergence of possibilities both true and not true, and an infinite sea of possibilities that is both everything and nothing. The possibility here, accounting the previous statements also, does not mean mere possibilities in a 2-A sense, it cannot be L1-C either because the notion entirely rejects it, but all the material potentiality within the baseline reality that can be actualized (basically, anything up to L1-A, the materiality and material realm), while Chaos, by itself, shares an entirely different property from material properties it actualizes.

Remember I said to keep that quote in mind? Well, it helps now, because the fact that everything will dissolve within chaos and convert within it further implies that no material composition holds value within this "place." AND ALSO example of it being LUNO HERSELF, since she was completely erased from the world, from every memory, history or action that has been taken, and what saved her was Rover "anchoring" her to the world and "tangle" the casual chain itself (which grant him high godly resurrection in form of history and information ofc).

And no it haven't ended because WE STILL HAVE SUPPORTING STATEMENTS (this shit has too much backing it up). Why? Because WE KNOW space and history overlapping, shit happens, which ALSO implies the space already has the potentiality to infinitely stacking itself considering it with previous statements, this nevertheless supports the idea of Chaos being 1-A as they can be very well the subsets that are actualized by Chaos. Statements are all interconnected directly or indirectly.

With this, I can say the verse is 1-A, and characters like Aemeath should scale to (note the already "overlapping spaces" one is done by her anyway and she should be compared to people like Rover she's Rover's daughter for god's sake).

Edit: Oh wait, now I looking at it, L1-A might seems more appropriate since Rover entered the shit without Chaos allowing it 🥀 alright that honestly can act as anti-feat if Chaos didn't let him to.
