11.
The pain is almost as bad as the time their mother had put them into a corset. They hadn't even known why. It was just something she had decided to do for her own personal gain. Except the worst part is where it is centered on their own chest.
The ears pull out like feelers (they can't help but wonder if they've made a mistake) and then the rest of the pain happens and Nagisa cries for hours.
Nothing changes, not really. But their body feels looser, more relaxed. And the blue as ocean gem remains on her open palm.
Nagisa wakes, and there are whispers, all kinds of whispers, burrowing into their brain. It's uncontrollable, loud, but they say everything that they need.
That person will hurt you. That one will keep you safe. That person is strong enough that person is dangerous.
Threats or not threats. Help or no help.
Survival. That is their gift now.
