Ryu has lost everything, but she is a survivor. A desperate message from her foster mother in the last moments of her life beg two things of her. First, that she find and protect her foster sister, and the second that she turn to the mysterious teacher, who runs a shelter in the warehouse district, protecting those who can't protect themselves. Under his tutelage, Ryu learns how to fight, so that when the killers return to finish what they've started she's ready. Ryu is more than they could ever have imagined, or is she? She is the fulfilment of an ancient prophecy about the return of a lost god and a long-dead blood line of warriors. She is the last dragon.
