In this world, the sun split open like an egg, introducing the galaxy to five ancient beasts made to rule the stars. ​During the apocalypse, a 12 year old Lucy is traveling with a chatty soldier named Blu and her robotic nanny CG. When exploring a ruined city, the group finds Mole, a timid subway motorman with no memory of who he once was. At Lucy’s insistence, they bring him along with their team, ready to face the wasteland together.
