Vatista is an Autonomic Nerve--a non-sentient biological weapon in the form of a young girl.
She awakened upon detection of anomalies within the Hollow Night and successfully eradicated Paradox, as instructed by her commander.
With peace restored, Vatista was about to return to slumber.
But then a new threat revealed itself: Kuon the Aeon, who threatened great tragedy to the world of humankind if left unchecked.
However, Vatista never received orders to act. And so, she sets out to do battle to save the world once again--this time of her own volition.
