Several Eidolons containing unbelievable amounts of energy are removed from a girl's body? Sure sounds completely harmless to me.
This is a fantasy world. Things can work however. It's described more as magic than energy, so the capabilities of that and how they can work with one's body is an infinite amount of possibilities.
I'm through right now. I got some work to do. It seems like you're arguing just to argue when you really know the deal.
