"Reinhard speared Ren's Holy Relic which affected Twilight Beach, opened a hole in there. So even if you try to argue Ren houses Marie completely (which is wrong anyway), nothing debunks Reinhard LLT reaching realms beyond outside Throne domain which encompasses all dimensions in existence"
This is confusing to me. Does LLT kill Marie via striking Rens holy relic or does the spear actually appear in the twilight beach and strike Marie? I feel like this is important to clarify.
The LLT doesn't kill Marie for one.
I'll try and explain the scene as best as I remember it. But tbf, I don't remember very much, but it will still help to bring context to the matter at hand:
After Ren rushes Reinhard and goes to slice his neck off, something happens. The scythe doesn't pierce Reinhard's neck, Reinhard smiles at the attempt and processes to grab the scythe with his hand and crushes the scythe into pieces.
For an instant, Ren believes himself to have killed by this action because, when he faced another user of Die Ewigkeit,
Rote Spinne, and when he destroyed that user's Holy Relic, that user was killed. He passes out and is captured shortly after.
We are given a scene showing that Marie is, in fact, still alive, and is within Reinhard's castle.
Later, when Ren awakes and is brought to Reinhard for a discussion, he asks Reinhard why he isn't dead - Reinhard laughs. He then asks Ren why did he believe he would die, Ren explains what happened to Spinne, and Reinhard clarifies that the reason that Spinne died wasn't because the Holy Relic was destroyed, but that the "soul" that resides within the physical shell of a Holy Relic was destroyed.
What Reinhard destroyed was the outer shell to Ren's Holy Relic, and that he made sure to persevere the "soul" within - he states that it was a simple feat. Ren silently disagrees, comparing it to crushing the shell of peanut without crushing the nuts inside.
Knowing that Marie's alive, Ren demands her back and threatens Reinhard if he already hurt her. Reinhard agrees and states that he is not the kind of man to touch his best friend's woman.
At the end of their conversation, a light flashes, blinding Ren as suddenly he feels a weight being thrown upon him. Reinhard wishes him farewell and disappears.
Later, Ren wakes up once again to Marie with him once again. He immediately begins checking her body for any injuries. Marie then does something out of character for her, she begins to feel nervous from Ren's intense staring at her body and declares that he is being a pervert.
Ren is thoroughly surprised by this, as is the audience. Marie, up until this point, was rather child-like and innocent, she was completely oblivious to the world. For her personality to make a 180 is quite jarring.
The reason for her change in character and her new array of empathy is because the LLT actually touched her, leaving a small hole, allowing her to intake new sensations and emotions that, while common to people like you and me, were completely alien to her till that point.
That's mostly what I remember, I feel like I am forgetting some important stuff, but whatever. So...
Reinhard destroys the physical shell of Ren's Holy Relic in their brief "fight", while his spear - like ALRF said - went to the Twilight Beach (which is a space outside the 1-A Throne), making a hole in space to get there to effect Marie.
So yeah, the spear can travel through 1-A space.
Which makes a lot of sense actually, as Reinhard was specifically designed to kill Mercurius by Mercurius. And logically, why would Mercurius have Reinhard's spear always have the power to kill him, but not the ability to reach him? That makes no sense, really.
