IMO
If her wish and abilities mainly revolve her, than she should only be able to erase things that she has an impact on, memories of people, it should like, only be things that involve her.
E.G. If she was/wasn't really there, What she did/didn't do.
I think erasing a person is a bit much, because they're an entirely different person.

Like I said though, In my opinion, your characters erasing powers should only effect things she has had an impact on or things that she owns. That's how I see the wish. If she wished that she had never existed, her powers should revolve around effecting things that were of her... ahaha. Other than that, I like the character .-.

I agree with you on that, though I respect [@TheWindel]'s final word. Nevertheless you shouldn't worry since we will be keeping a close eye on that to make sure her powers don't become a problem.

You know what I have to just make a hypothectical, what if she had an impact on the whole world ? and felt depressed enough to kill herself and the world and made the entire world not exist ?

That's absolutely impossible IMO, since to affect the whole world like that she should have to be at least as powerful as Madoka and Homura in their Ultimate forms and we all know that this is impossible for a number of reasons.
