I don't think she's a hunter,I just think she isn't HUMAN.

And the only reason why I thought of this is because of Gon's visit to Whale Island. Ging was about to say something important about his mom before Gon stopped the tape. I remember Killua saying something like "Are you sure you don't wannna listen to the rest of the tape?" I think that was Togashi's way of hinting that she is important. I could be totally wrong. But from what I've read so far, Togashi has been dropping hints since Yorkshin.
