Daigo doesn't speak anymore. Not since he killed that rabbit on the playground at school. His sister, Kiriko, is worried. He's bullied. He sleepwalks. And their father is no help, trapped in his own grief and illustrating fantasy worlds where families are happily reunited and no one dies. They never should have gone to that 3D movie.
The one with the stuffed rabbit that floated out of the screen. Now Daigo is missing. He's in danger, and Kiriko will have to follow him into a world of nightmares to discover the truth. And the truth is worse than any dream.
