The story begins shortly after Takeru has liberated his sister from the dogfight circuit only to discover that, outside the cicuit, Sayoko's brain has a "self-destruct" mechanism and that she is dying. Takeru has one week to find a way to cure his sister or return her to the circuit or she will die. Adding to the problem are the "dogged" efforts of the Albion Corporation to recover "their stolen property" as well as a cast of characters who all have their own scars of some sort...
