Kia was picked up by the agents of the NEXUS in the Bielefeld of the year 2089. Since her world was invaded by giant cicadas, and Kia also had little prospect of a successful future, she was taken to the present by the agents without further ado.
There, faced with the decision of either returning to the future with a memory wipe or joining the NEXUS, she chose to stay. Since then, Kia has been trained as an agent of the rapid reaction force.
