Screen saver
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.
