Archaeologist Koichiro Kamishiro searches for a lost divine message hidden in the traces of ancient civilizations. Finding a pair of mysterious crystals brings him closer to that goal, but it also draws the attention of forces willing to kill for the secret they contain.

His investigation across Japan becomes a race against rival agents and supernatural powers. As the clues point toward a threat to Earth itself, Kamishiro must determine whether the forgotten message offers salvation or another means of bringing disaster.
