Wait how wouldn't it work. Event Negation is the power to negate anything litteraly anything from Space-Time. Examlple: Cornelia can use Event Negation to prevent the Big Bang from ever happening. Now, you may think that's Op, but what's the point of an Bad Guy who gets beaten easily. Yes, I made Cornelia to be a villain for the Rp, But she will die later on, I mean, Villains always die, but it will be hard to kill her. Anyways, not trying to fight over this, just in case.
Disclaimer: Not saying Cornelia is op btw.
I'm scared of what Meruin is going to do now, litteraly.
