Story
This anime is set in year 2130, 50 years after World War Three (the exact date is not made clear). The war has left a crater where Tokyo once stood, a place filled with contaminated rubble. This spot has no electrical power, and because of this, the crater shows as a black spot in the night sky. The Black Spot is a place where outcasts come to live, and because of the contamination, certain of these outcasts gain various powers (or "fragments"). Those with powers become known as Needless.
