After arriving at the barrier workshop, Reia steals an item that is supposed to help stop Gaia, and reveals herself to be Neizai. As Ulyte sometimes transforms into Reia, he dons the disguise of Neizai whenever he switches bodies, so that no one knows of Reia's existence, or the fact that he and Reia are in the same body. In the last episode, when Ulyte's body finally fails him for good, Reia takes over permenantly.
