Omschrijving

In an alternate version of the present, Tokyo has been decimated by a shocking terrorist attack, and the only hint to the identity of the culprit is a bizarre video uploaded to the internet. The police, baffled by this cryptic clue, are powerless to stop the paranoia spreading across the population.

While the world searches for a criminal mastermind to blame for this tragedy, two mysterious children-children who shouldn't even exist-masterfully carry out their heinous plan. Cursed to walk through this world with the names Nine and Twelve, the two combine to form "Sphinx," a clandestine entity determine to wake the people from their slumber-and pull the trigger on this world.
