Tokyo is sealed off by the Japanese Self-Defense Forces, trapping everyone inside. Mythological demons have begun appearing all over the city, summoned by mysterious Nintendo DS-like devices called COMPs. The hero and his friends receive COMPs of their own from the protagonist's cousin, Naoya, and quickly begin using demons to defend themselves and others. However, the COMP also comes with a few other disturbing features: the Laplace Mail and the Death Clock. The Laplace Mail is a mysterious e-mail sent to the COMPs that predicts the future, including the deaths of people and the arrival of powerful demons."
