Space began to crack, and soon the illusion vanished, showing the Flame Imperator's hand piercing Zatiel's skull and sending a force that sought to morph this one's ego.
If the True Will were the one containing Zatiel's will, it would have been much easier for the Flame Imperator, but the one holding the ego's core was the True Name.
That was a quality only Zatiel Daybreak possessed, granted by Rex Depravita Samsara Universalis Causalitax. That is why it did not matter if his True Will, True Soul, or True Doomsday Body left him and formed Samsara Incarnations.
"I know that you will not surrender until the end, but I tell you, it is futile. I have isolated every fragment of your existence, and there is nothing you can do to stop me. It is only a matter of time before I leave your ego as a blank slate. That will mean that the moment I fuse with you, I will have 100% certainty of becoming the winner in our battle of wills."
