Satori is the Mistress of the Palace of the Earth Spirits after the underground city was separate from Hell. Her ability to read "minds" makes various youkai and spirits fearful of her, while leaving her well-loved by the animals that normally can't be understood. With these animals as pets, she manages the ruin of inferno where her home stands. During the events of the Subterranean Animism the Heroine (from above ground) invaded her home. After an encounter, she permitted the Heroine passage towards the Hell of Blazing Fires to ask her pets about their supposed problem.
