BDE type 2

[HakutoRei000]

Every creature in the "Outside" space is initially just an energy form with no body, form or identity.

They have a form only when they enter a room, and this "Room" can be said to be a canvas, TV, program or notebook, in essence, they have a shape to fit their place.

But this was done not for themselves, but, the space itself, if they entered in its original form, which basically has no form like "Space" (dimensionwise not directly physical), that space that will accommodate their "Existence", which does not even have emptiness.

And ultimately turns the entire Space into emptiness.

Now this creature is said to be a formless entity that only takes form when it enters the room which is said to be a canvas, TV, and book.

They are not bound and instead Space adapts to their existence (despite being Destroyed), Whereas Space is a metaphysical concept that forms all of Reality and contains it.While Space itself is like beyond the edge of the universe. There is but it is impossible to ever achieve

The description aligns with BDE Type 2, if that's what you're asking.

The creatures in their "original form" (formless energy, an "Existence" that "does not even have emptiness") are stated to turn the metaphysical "Space" (which "forms all of Reality and contains it") into "emptiness" merely by their presence. This indicates their true nature is fundamentally superior to and incompatible with the foundational fabric of that reality, to the point of negating it.

Their true state ("no body, form or identity," "no form like 'Space' dimensionwise") and their origin from "Outside" suggest they are not bound by the dimensional or existential rules of the "Space" they can destroy.

The "Room" they enter being likened to a "canvas, TV, program or notebook" strongly implies a Reality-Fiction dynamic. If they are from a plane that views this "Room" (and by extension, the "Space" it's within) as a lower, perhaps fictional construct, this supports a 1-A standing, which inherently includes BDE Type 2 (qualitative).
