Time & Space.

ever wonder how all of existence came to be? animals, thoughts, habits, fiction, everything. in this branch of the story, everything started akin to the big-bang. how is it different than a/the regular big-bang? everything. everything started all at once like the big-bang. hard to comprehend, no? think of it this way: what would happen if all that could fight, fought everything else that could also? choas. a complete, true free-for-all. the difference being that instead of bloodshed, they were wiped from one's own "memories". and so came to be Earth, and all. ...don't think of it too hard, just know that U.A. here means MC wasn't affected by this big-bang, and now can 'transverse' all of creation. but don't forget! MC's U.A. only works against... who?

btw, as for how they "transverse" up to y'all ofc, seeing how I left it open-ened, but for me I'd think it might be vast void they're in and they stick their heads in bubbles of universes. think of Heavenly Record Eater.
