A world within the Palace created by Futaba Sakura. The Phantom Thieves of Hearts plan a heist to steal Futaba's heart after making a deal with her to stop a group of hackers called Medjed that threatens to declare war against them. It appears as a large pyramid surrounded by a city in the middle of a hot and sunny desert. The interior is cooler because of Futaba's cognition of living inside with air-conditioning. Shadow Futaba has been fighting for the control of Futaba's mind with the Sphinx, the Cognitive existence form of Futaba's deceased mother Wakaba Isshiki that embodies the representation of Futaba's self-loathing and belief that her mother hated her.
