Sealing involves placing a character into another object. Sending them to an empty space isn't sealing.
Also, your argument seems incoherent here. You say that it's not stated that the space has one exit, but then directly quote Altair saying that there was an exit and she found it.
It is sealing if you send them to a realm which cannot be escaped from. Also no, my argument is not incoherent. The realm doesn't have an exit. Altair "pointed out" one gate that is an exit amongst infinite ones that supposedly aren't using the logic "If there is a gate then there is an exit" aka its a feat for Altair's hax, and not a prexisting condition of the realm having a gate. Also funny enough how in a few seconds she conveniently found an escape gate out of an infinite number of gates in an infinite space, which would be impossible to do so unless she had any ability to help her with that.
The nature of what the statement about Altair's "concept" refers to requires a separate discussion, since it's not in the OP and is a whole can of worms unto itself, but they don't say Hachimon Tonkou was used to "attack" Altair's concept, and there's nothing saying the realm didn't already exist. In all likelihood Matsubara was responsible for creating the realm.
It's outright
given in the profile and
discussed and accepted by the very (ex)admins here who made the Abstract Existence and Conceptual Manipulation page.
The video clip I have provided gives enough context to put everything piece by piece together. They say that they need to attack Altair's concept as physical/magical attacks are not working, and they immediately use Ionion Aphoria which, as per both the anime and even the guidebook, uses the concept of Hachimon Tonkou. So naturally, the logical conclusion is that Selesia used the Concept of Hachimon Tonkou to attack the Concept of Altair.
Not to mention,
Conceptual Manipulation was already accepted here previously but they're all based on the old concept types and currently, it'd fit the concept type 1 category of being an independent concept, or at least type 2.
As for "warping 3000 worlds" that still requires taking the chant as a literal description of power even though the ability activated by the chant does not accomplish such a thing, and Selesia has never demonstrated such a power, so I'm still a disagree here.
Given the fact that Hachimon Tonkou itself is described to be manipulating directions including and beyond the geographical ones, and I have pointed out how directions is associated with Space-Time, then it fits perfectly with the given statement of "Warping Sanzensekai" which, if taken either literally as "3000 Worlds" or contextually as "All of Creation", will give Space-Time Manipulation.
It is not. I may not speak Japanese, but I am a professional translator. The word "can" is not something that would depend on context. At best I could see a sentence like "is it possible for him to [verb] or "is he able to [verb]" could be turned into "can" but these two sentences:
"No shadow exists there"
"No shadow can exist there"
Are substantively different in a manner that can't be handwaved. Perhaps it is some remarkable quirk of Japanese that could allow such a thing but I am extremely skeptical and would require confirmation from somebody other than Qlipoth.
Skepticism is fine. Heck I even asked ExecutorN0 about the translation for that part and he says its fine even though he did not say anything about "can" part. Though, even if you say "No shadows exist there", it still makes the realm a void realm given the description "Its not a hell of ice or fire, and where reason reduces to chaos. No form, meaning, or shadow exists there". Aka a roundabout way of saying its purely a void realm that not even shadows or meanings, aka metaphysical aspects, can exist in there as its a place where even reason is reduced to chaos.
The statements made about gates having exits, and there being one exit here, would seem to directly contradict all of this.
The statement doesn't say gates having exits. The full context is that Selesia trapped Altair in a realm with Infinite Gates. Altair escapes out and says she used the logic "If there are gates, there will be an exit" and how she escaped by "Pointing out a single exit amongst an infinite space" aka finding that one exit gate amongst an infinite ones. Its a testament to Altair's hax, and not any inherent characteristic of the realm.
Yeah, but the word "concept" is not always going to mean what we on VSBW use it to mean, hence my disagreement.
Given the context, "Concept" here would fit in as a Concept is used to attack another Concept.
The translation stuff, if we could get third party Japanese translators on the wiki to take a look, I'd appreciate it.
I don't know any current translator here except Chasekillen (who is busy) and ExecutorN0 (who is also busy). So I'd appreciate if anyone here can ask for a wiki translator.
So, according to this translator, the verb used definitively rules out "create" as an acceptable translation of the verb
That's not what they say. They say that the verb usage implies the pre-existence of the gates as they appeared or brought forth. But they also don't say that its a "Definitive", as I have pointed out how "出現" translates to "Appear" but also could mean "
Coming into Existence" aka create. Though, if a Wiki Translator can confirm that the sentence indeed means "Appear" with no other meaning for "Create", then ofc Selesia would lose Void/Chaos Hax and AP as they'll all go to Matsubara, the original creator of the power and realm.
