To combat this new wave of wrongdoing, the Recently Armed Police of Tokyo was established in hopes of hunting down criminals with lethal force.

For citizens of the Ken Empire, justice is a myth.

Taito's mystical powers steer him toward a violent showdown with Keiro, and if used recklessly, his newfound abilities could shred the very fabric of his being. To master the art of control and become a heroic martial artist, Taito must seek the guidance of others like him: the seven star-born warriors with the strength to shatter a corrupt empire.
