It began serialization in 2005 issue of the monthly seinen manga magazine Comic Beam.

Ed Sizemore found the art in the first part of the first volume distracting, and the lead character to be unsympathetic, but felt that the manga was well written. Deb Aoki described the manga as a "glass onion of a mystery". Katherine Dacey found the story "immersive".
