By the 2060s, robotics technology has become extremely advanced, including cybernetics. World opinion begins to turn against robotics, leading to the U.N. declaring a unilateral ban on further research in 2067. Japan, being home to robotics pioneer Daiwa Heavy Industries, strongly protests this ban, but is unable to prevent its passage. In protest, Japan withdraws from international politics. All foreigners are deported, and further immigration is prohibited. In addition, the R.A.C.E. network is constructed 270 offshore installations that cover Japan with an energy field, nullifying all communication with the outside world and making satellite surveillance impossible. Trade and diplomacy continues, but Japan vanishes from the world scene.Ten years later, the United States Navy special warfare unit SWORD is trying to trap a Japanese informant for Daiwa in Colorado. The instigator, Saito, escapes by cutting off his own leg. Analysis shows the leg is made of biometal. SWORD suspects that Japan has concealed extensive development of banned technologies. They embark on an unapproved scheme to infiltrate Japan and to find out the frequency of the R.A.C.E. network, enabling SWORD to gather intelligence on the country. Although the agents successfully enter Japan, they are detected by security forces before they can transmit their data. Vexille is the sole SWORD agent to evade capture, and only her lover Leon survives to be taken to Daiwas headquarters. Vexille awakens to find Tokyo is now a shanty town ruled by Daiwa. A small resistance movement opposes the company, and uses Vexilles transmitter to successfully transmit the distortion frequency. ........
