On the snowy day prior to their graduation ceremony, the members of the Phantom Thieves of Hearts have gathered at Café Leblanc. Suddenly, the ground begins to shake, and the front door emits a suspicious glow. When they open the door, they find themselves in a different world, reminiscent in appearance to the cityscapes of medieval Europe.
When the Phantom Thieves are attacked by a mysterious group, they are saved by a woman named Erina. The Thieves agree to join her in her revolution.[1]
