Ayame and Reiko seek out an ancient manuscript that reveals more about the prophecy. It speaks of a "key" that can either lock the cycle of rebirth forever or shatter it, freeing Ayame from her curse but plunging the world into chaos. This key is hidden in a distant land, guarded by a powerful being known only as The Watcher. Ayame's memories of this place are vague, but she feels drawn to it, certain that this is her only chance to break free.
