There's a war going on and humanity is the prize. Caught in a battle between two supernatural forces, five junior high students are killed. But Constance, Jonathan Avery, Maria, and Danielle return from the dead—and they've changed. They each carry a piece of a soul stone and with it they have extraordinary powers. Now they can summon weapons from thin air and even start fires with their minds. With these powers comes a connection they never wanted, and coming back from the dead hasn't wiped away the grudges between them. When one of them loses themselves to the power, they are soon caught in a battle against themselves and an enemy that wants to make sure that this time they stay dead.
