A ruined world, a girl covered in scars, and a machine that lives in the face of death.
In the year 2190, humanity is on the verge of entering a new era. But in a time rife with war and plague, conspiracy and evil, no one can be certain what the future holds.
To stand against the immense conspiracy known as the Thirteen Sovereign Powers, Crow, a military android, accepts a mission wholly unlike her nature. Alongside her colleagues and a young girl with supernatural abilities, Eliza Yang, she will fight in a vast cluster of offshore cities called the Corporate Union. Their battle may determine the future of humanity.
