In a quiet Tokyo neighborhood, seven teenagers wake up to find the mirrors in their bedroom are glowing.
With a simple touch, they are drawn from their solitary life in a wondrous castle filled with spiral staircases, attentive portraits and twinkling chandeliers. In this new shrine, they are confronted with a set of clues leading to a hidden room where one of them will have a wish granted. But there’s a catch: if they don’t leave by five o’clock, they’ll die.
Over time, a devastating truth emerges: only those who dare to share their stories will be punished.
