It was at this point that Kairos remembered.
If he didn't see the system notification, that meant he didn't kill the enemy. Although the body he thought he was fighting was now lying motionlessly on the ground, That thing seemed as good as dead.
However, he gradually came to the conclusion that the body was never actually alive in the first place. Rather, it was only something controlled like a puppet on strings.
As for the thing controlling it...
That would be the owner of the giant eye that was currently staring at him.
From what it looked like, the two large bony hands began peeling away the fabric of reality, slowly revealing that the eye was part of a skull. This thing also only had one eye, just in a different socket from the other body.
Peeling back further, the full skull was revealed, while part of the background was also shown, which looked awfully similar to the static one would see in a tv without reception.
