BLAKE: DEMON SLAYER
Reincarnated and killed several times, Blake Listerio a child born from a demon Lord and an Angel was casted down from the supreme realm to dwell in earth, grow his powers so that he'd be the protector, savior and the only one capable of stopping what is to come. But the moment disaster came, the Supreme realm went in an all-out battle dragging in the Megaverse with it. In the end, one man was left standing.
Black skull's destruction 3
The world twisted, blanched and...
A rift tore through reality instantly pushing Blake, Evie and Gabriel out of it.
Steel God had used his power... the newly improved power he had... to create a miniature gateway through the fabric of existence.
Tearing through the void or space is different from tearing through reality or the fabric of existence.
The void can increase the distance between a person from another...
Space can shift directions completely but reality can instantly move one from regions to regions, dimensions to dimensions and universes to universes.
Which means, if one is not particularly noted on where and how their gateway through reality is placed, they could from their parallel universe and enter another parallel universe.
But that didn't happen when Steel God tore a rift through reality.
