Summary
Existence Erasure is the ability to erase things from existence. Going beyond material destruction, complete existence erasure annihilates the body, mind, and even the very soul of the target, rendering it as if they had never existed at all. The end result leaves no trace of the target, making it exceedingly difficult to counter unless the victim has displayed resistance to such abilities. More powerful users can go even further, going so far as to erase the concepts that make up reality itself.
