It was revealed that she is the biological core for the Ryvius (one of a series of sentient ships using creatures called Vaia). Although not human, she based her form on the body of a deceased young woman drifting outside in space by the Ryvius. That young woman was the daughter of Conrad Vicuss, the man in charge of hunting down the Ryvius. When Neya herself appears before Conrad in one of the last episodes, it is understandable that he should be shocked to see his own daughter acting as defender and guardian over the Ryvius. It is through Neya's intervention and assistance that those aboard the Ryvius survived their ordeal, and she continues to act in her capacity as the ship's Sphix - an alien defending the Ryvius and her young crew.
