After the battle against the Ceremony Master Kurosawa (and for the final battle against Kusabi), you may be tired and do not want to use any Healing Herbals or Holy Water in the long underground passage. You must not fight the enemies there. You can walk until an enemy appears then run back to spiral corridor. Then, go back to underground passage. The enemy should have disappeared. Continue ahead, and if an enemy appears, repeat the process. In this underground corridor, there is a place with an "S" shape. If you meet enemies after this place, go back to the "S" passage until the enemy disappears. You will finally arrive at a place where the enemy appears at your back. Do not look back. Just run to the ceremony place to fight the Kusabi. Note: There is one mirror stone in the underground passage.
When one of them raises her hand after the red circle fast, do not attack her or you will be attacked by her sister behind you, If she raised her hand after the red circle slowly, this is the real spirit and you will not lose film on the twin's doll, if you know which is the real one. Also, notice that the Twin's spirit has red lips and the doll does not. This will make it easier to learn which is the real one.
Keep the game unpaused, and out of the menu/map screen. Allow Mio to remain idle for exactly five minutes. A ghostly image of a woman's face will fade onto a random point on the screen (looking at you) for a moment before disappearing. Then, the screen will get blurry for a moment and the woman's face will fade back in on another location on the screen. This will keep repeating until you use the controller again.
