The Princess of Monsters, Hiro, and the gang find themselves caught up in mysterious events. A tragedy that repeats itself within a closed loop. A recording device that holds keys to the future and transcends time. A mansion that expands endlessly. A labyrinth that holds the royal family captive. And who is the figure that Hime comes across, deep underground?
