I'm lost so is the Knight the Abyss King true form or someone else from the other world too? If so I'm stil even more confused bc it seems to be a direct link to the abyss and the real world seeing how it looks like it was able to call forth that demon and use its version of that skill. I hope we get more info about that knight
