As Miaka and the three seishi approach Taiitsukun's home on Mount Taikyoku, the controller of the Universe of the Four Gods decides to set them a test by trapping Miaka in a mirror and replacing her with an evil reflection of herself. As her evil duplicate begins causing havoc among the seishi, Miaka realises that she and her reflection must share a connection, and resolves to put a stop to the evil Miaka by taking her own life.
