Welp let's have some fun.
Lets start with the manga thing.
The demon world is called as the darkness because
that is it's name, its the world of darkness, in this realm there are several dimensions (of unknown sizes) but we know that the demon world is indeed infinitely bigger than any of them including the human world or the world of light which is described as just
a ray of light in the
endless darkness that is the demon world. This isn't flowery, its literally talking about how they compare each other or in other words how big one is compared to the other.
Furthermore one such realm is the mirror dimension, this dimension which is a
perfect copy of the human world (the human world is Low 2-C if it wasnt obvious enough) yet it is only the "entrance" to it. There are more like Mundus dimension which is an
infinitely expanding universe beyond human understanding yet it only serves as a battleground for Mundus and Dante
Basically none of this shit is flowery language. And as per the tiering system and the FAQ this perfectly qualifies for Tier 1, specifically Low 1-C:
Low 1-C: Low Complex Multiverse level
Characters or objects that can affect, create and/or destroy the entirety of
spaces whose size corresponds to one to two higher levels of infinity greater than a standard universal model (Low 2-C structures, in plain English.) In terms of "dimensional" scale, this can be equated to 5 and 6-dimensional real coordinate spaces (R ^ 5 to R ^ 6)
A.
One of the more straightforward ways to qualify for Tier 2 and up through higher dimensions is by affecting whole higher-dimensional universes which can embed the whole of lower-dimensional ones within themselves. For example: A cosmology where the entirety of our 3-dimensional universe is in fact a subset of a much greater 4-dimensional space, or generalizations of this same scenario to higher numbers of dimensions; i.e A cosmology where the four-dimensional spacetime continuum is just the infinitesimal surface of a 5-dimensional object, and etc.
Second is the 9D stuff.
The soul is stated to be a basic nine dimensional item, in a geometrical sense as the name says (or the words used in this case as shown by Cyber) which
originates and returns to a higher dimension said higher dimension being the demon world as the
blog shows. This has nothing to do with the eightfold path or the nirvana shit.
This would make the demon world capable of creating 9 dimensional items which as it's stated to be the entire origin of said object and on top of that it's stated to be higher dimensional. Just how 3D beings get created in 3D places. A 2D realm does not have the space within it to create or be the origin of a 3D being the primordial chaos is the origin of 9D things this should, especially when it's stated to be higher dimensional, make it also 9th Dimensional. This is according to
this thread and what the page says:
Also we were told that infinite hypervolume from higher dimensional spaces qualifies for higher tiers (both in the thread linked above and
here)
which supports our perfect wank
As a side note even fodder demons see the human world as "
insignificant and like insects to them" and Arkham (a schoolar about demons and all that shit) says they are
like looking at infinite
Finally this. This argument was kinda destroyed when we had to explain how Pluto did absolutely everything. The creation of the light aka the human world did not separate the realms,
just brought chaos and pandemonium.
Also if there are scans missing just ask, I got lazy mid way through this
