This is to the person who called everyone stupid, yes it is all done by darkness, that was stated in the manga and it was specified that it wasn’t his sword skills, hence why it is a “Full React”, Merlin even said it didn’t rely on his senses at all. Anyways, this technique takes an immense level of concentration. So even though every demon is physically capable of it, most if not all other demons would not be able to reach the level of concentration, control, and power required to actually use Ominous Nebula.
