Unlike everyone else, Kaworu doesn't collapse when he arrives though he feels the sensation that brings everyone to their knees. A twist and a pulling sensation like being collapsed inwards and reformed with your elemental pieces into something new.

But it can't collapse him, there's nothing to reform him into in this world. So he exists on a periphery, something like a Throneborn and something like an angel and something a bit like a human. His outline too sharp, like he's standing in front of the world within it. An extra cel layer on top of already complete frame.

Still, he can feel its pull. Like if it cannot collapse him, it will simply unravel him bit by bit until he's nothing but a pile of string to be made a proper Throneborn.

He sits on the edge of the wall, knees to his chest, looking much more like a bird that's fallen from its nest than anything divine. However, the the halo hovering above his forehead and the faint outline of wings made of light reveal his true nature.

For now, Kaworu just looks out over the land that's real and not and thinks about what he must do.
