Other than attacking the temple, Xion also stabs a woman named Nagi, imbuing her with his power as well as that of Gaia's, making her both his lifesaver and enemy.
A year later, the dragon is about to break free again, causing disturbances among the zoanthropes triggering earthquakes.
In Nagi's ending, in addition to sealing the dragon and saving Ryoho, she kills Xion and the Unborn.
