It also does not infer that Location X is within the jungle, such as:
"The warriors move through the jungle, going to the city."
"The tourists move through the tunnel, going to the skyscrapers."
Whatever it is they are "moving through" is not necessarily a part of, or independent of, the location they are going to. This can't reliably be used to determine the nature of the realm they are going to.
However, there is no preposition in this sentence, so "through" is somewhat interpretive.
So I have a simple question.
If you knew that the word, “that” was not in the Japanese, then you would also know that the phrase “going to” isn’t there?
突如として、空中に渦があらわれた。 超次元空間、現! セーラー戦士たちが次元空間を移動する。この三次元にはない、時空を超えた世界 不気味な音に包まれている。
Totsujotoshite, kūchū ni uzu ga arawa reta. Chō jigen kūkan, gen! Sērā senshi-tachi ga jigen kūkan o idō suru. Kono sanjigen ni wanai, jikū o koeta sekai bukimina oto ni tsutsuma rete iru.
Suddenly, a vortex appeared in the air. Hyperdimensional space, now! Sailor warriors move through dimensional space. A world beyond time and space that does not exist in this third dimension is surrounded by eerie sounds.
So my argument is wrong, fine. But so is your comment. The senshi are not traveling through the dimensional world to go to anywhere.
The syntax. Is
A is moving through B. Description C.
Examples:
The warriors are moving through the Jungle. Description of the Jungle.
The tourists are moving through the city. Description of the city.
The planes are moving through the sky. Description of the sky.
The dimensional space is what is being described as being beyond the three dimensional realm.
And before you say, the description is not for the dimensional space, that’s illogical. There is zero reason to believe a description isn’t for the location it’s immediately after. There is no other locations mentioned.
“A moved through B. Description C of new location D” makes no sense when there is no mention of the cast leaving that dimensional space. No sense when there is no mention of the cast using that location to go to another location.
“The warriors travel through the jungle. Description of a city.”
“The tourists travel through the tunnel. Description of a skyscraper”
So in conclusion, this dimensional space is being described as not being apart of the 3 dimensional realm.
