@SomebodyData I just checked here on crunchyroll, but at this point it might just be flowery language, it would be for example Zod telling Superman "the Earthly universe with the Kryptonian universe".
I wanted to know something related to Yubel's statement, not something that can be flowery language between Judai and the Aqua Dolphin, which is what I will argue next;
Here is episode 62 on Raw, and what Aqua-Dolphin says to Judai is this:
そう だ よ 重大 君 の 自由 な 心 が 生み出し た カード が 君 たち の 宇宙 と 我々 の 宇宙 ネオ 宇宙
That's right, Judai. Your unfettered heart has created those card that is a link between your universe and our universe, the Neo-Universe.
Here what Neo Aqua is talking about doesn't even refer to the planet where they crashed with Kaiba's capsule, but rather the imaginary universe that the child Judai longed for when he was just a child watching people duel, and which gave him the motivations to create the neos universe. In this way, when the cards became alive, the link between Judai's heart and that imaginary universe he longed for was created between him and the new spirits. That is just a flowery passage.
Of course that's not all that changes, the kanji used in that sentence is
宇宙 where the etymology is very manageable according to the context, it can be used in outer space even universe in its actual size, but it was not the universe in its actual size, but only the relationship between the Judai and the cards. So regardless of whether it's Neo-Space, or Neo-Universe he mentioned it's going to have a single meaning and totally different from Yubel's Statements.
Given that said let's move to Yubel's statements.
どちら が この じゅー に 十二次元 宇宙 から 消える か ここ まで 君 を 導く ため に 消え て いっ た 君 の 仲間 達 は 確か に 別 の 次元 に 幽閉 し て いる
Which one of us is going to disappear from this twelve-dimensional universe? It is true that, to lure you here, i locked all of your vanished friends in another dimension
Basically the difference here is the use of dimensional with the previous kanji, being that
次元宇宙 and the last one being
別の次元.
- We go with a 12-dimensional layered universe, which would still give us a Low 2-C, but depending on the size of each one of these bulks, it could lead to an even higher tier
- Assume that these are spatially separated extradimensions, as for example the realms of Yggdrasil in the MCU, where the context is very similar to the one we are dealing with, portals for pocket and/or universally extradimensions through the Einstein-Rosen bridge i.e. a wormhole.
Something I almost forgot is that in
episode 153 Yubel says the following line;
じゅ十二にの 次元 に 分かれ て 存在 する 全て の 宇宙 僕 の 十 代 に 対する 愛 で 満たす と
i'll fill all the twelve universes that exists in different dimensions with me love for you, Judai.
I think it is quite noticeable the spatiality of these extradimensions being separated that are even called universe in another context than the flowery one between jaden and his cards.
