Sequel to "Phoenix From the Ashes." Saved literally from death, the Shiroiwa girls find themselves in a universe with aliens and metahumans. Unable to trust anyone, they depend on Mizuho — and a weapon beyond imagination — to protect them. Mizuho is determined to get their male classmates back…with help from the Moroboshi siblings and the Earth Defence Force. Will they succeed?

Three years before the Shiroiwa class faced the Program, a class from Tomobiki were made to kill or be killed. Now, unknown to the Greater East Asia Republic, Moroboshi Ataru has returned . . . and he has the power to save them all!
