Saying that the underside of the chessboard is part of the human domain is kinda misleading imo as it utilizes an analogy explicitly based upon the witch domain's perspective(That is being the underside of the chessboard), but regardless this is a minor detail.
This argument is based on the fact that the Ryuns, due to phase transition, travel independently of space, time and opportunity. The description of the reverse side of the chessboard fits well with this concept
How are you reaching the conclusion that the mirror is the same as mirrors in Higanbana? Based on what exactly? Where do parallel worlds even come from?
I think I've written this in CRT before
1) These mirrors have a connection with the spirits of Akujikishima (Yokayami)
2) They interfere with Beatrice's endless magic
3) The procedure of cleaning the mirrors that Kinzo did (the same procedure that Kyo did in Higanbana)
4) Same name in Japanese
Three issues:
1) Don't the 3 worlds in Trianthology form a full cycle? Like A views B as fiction, B views C as fiction and C views A as fiction? Assuming this to be true, this would be a very violent form of contradictory paradox that would oppose any notion of this "hierarchy" being ontological.
2) Don't we also see the kakeras of the 3 worlds side by side independent of each other? That would also contradict the idea of ontological difference as if the worlds were inside one another their kakeras(Which are stated to be the worlds themselves in Umineko) would not appear side by side, but instead inside one another.
3) Even if we entertain the idea that the hierarchy is indeed ontological it would be vaguely unquantifiable as its useless for concrete tiering assuming the cycle thing is true.
1 - 2) They do form a cycle. It's not the Kakers themselves, but rather the worlds in them that are linked hierarchically. This can be seen as a portal of some sort, as well as a hierarchy. In general, Kakers can exist within each other and this hierarchy can stretch all the way to the Human Domain, where they will manifest as emotions.
3) The purpose of this point is to demonstrate how not the strongest witches can bind these shards
Absolutely not. I have read through the whole post and you brought nothing that wasnt already known on the wiki, except the trianthology thing which hasnt been discussed on site but has been discussed before offsite.
I feel like nothing you said has any correlation to the tiers you have suggested. You might need to elaborate upon the reasonings for the tiers.
high 1-B comes out due to the fact that these mirrors do not simply lead to parallel worlds, but create an infinite hierarchy. And the properties of this hierarchy meet these criteria
(Characters who can universally affect, create and/or destroy structures whose size is equivalent to a countably infinite number of qualitative dimensions above a universal model, usually represented in fiction by endless hierarchies of layers of existence, each succeeding one completely trivializing the previous into insignificance, or more generally a space with countably infinite dimensions.)
low 1-A comes out at the expense of the Witches' Domain being superior to the Human Domain. You cannot enter the Witches' Domain without an invitation in principle
The Witch Domain, by the way, is already an infinite hierarchy
1-A is high 1-A theoretical. Out comes at the expense of Beatrice's ability to unfold hierarchies of mirrors at a higher level. Not only that, but in her world there are more layers on top of them
1-A high in Voyagers due to the fact that not even their true forms travel in a sea of shards. The true forms, on the other hand, are obviously higher up
0 to the Creator, for being superior to all 07-expansion
With Fezarin it's debatable. Although she was partially able to be in the third domain, it is only partially
