One Day: It is the year 2031. Humankind has been replaced as the dominant species by a race of monstrous insect-like creatures known as Blue. Sleeper Yuji Kaido finds himself thrust into this nightmarish world after being awakened from 22 years of suspended animation. Alone and surrounded by the Blue, Yuji's only hope for survival comes from an elite Sleeper Recovery Team, and a steely Mech pilot named Marlene. Cry: Yuji learns the horrible truth about the Blue. Their infestation of planet Earth has forced the human race to seek refuge in outer space. Marlene and the Sleeper Recovery Team have been given orders to bring Sleeper Yuji to space station Second Earth alive. But with the Blue lurking at every turn, things go not always go according to plan. Trial: Tired of feeling helpless in this hostile new world, Yuji pleads to be trained as part of the team. Marlene gives Yuki a crash course in weapons. Joey teaches him the basics of piloting an Armored Shrike. Armed with his new skills and his newfound confidence in his ability to survive, Yuji is ready for action. But against an enemy like the Blue, overconfidence can be deadly.
