Without warning, Japan has come under attack by mysterious invaders known as the Septentriones. Kuze Hibiki and twelve others each with their own unique personalities end up forming pacts with demons, making them the '13 Devil Summoners' - people who can call forth demons to provide them with the power to fight against the mysterious Septentriones.
But the world is set to end in just seven days, and the future now lies entirely with the choices of these 13 Devil Summoners!
