Night Watch
Lone wolf junior high school boy Hyogo discovers the world is actually an artificial reality created by computers to prevent mankind from going insane in the vast emptiness of space. Apparently, all of humanity is in frozen slumber on a vast spaceship looking for habitable land. But there is an enemy attacking them, and their only defense is the ten remaining Nightwatch spaceships, which look like monsters made from thousands of bones. One ship has its 'core' or pilot destroyed, and the back up stabilizing personality, Hyogo, awakes from virtual reality to pilot it. And for the first time a pilot is able to destroy several of the enemy...
As if this wasn't enough, there's also a serial killer on the loose -- actually a terrorist, aware of the secrets behind the world and trying to destroy the computer programs that live in the virtual reality along with us, supervising and making sure everything runs smoothly. Since he knows the truth about the world its laws do not apply to him, and he fails to die when shot, walks on water, etc.
Fans of the
Boogiepop novels will enjoy a few references to characters in this novel reading his Dengeki Bunko titles, and the last act revelation that the 'enemy' is actually the same alien intelligence that sent Echoes to earth in Boogiepop and Others. And of course, Kadono Kouhei is always very strong on characterization, using the younger ages of the characters to do some nice work on the new, incomprehensible feelings welling up inside them.
