[The battlefield belongs to women. Men should stay out of it.] This is the era when the Vurdians, an extraterrestrial intelligence, rule the galaxy. Hokuto Kisei, an ace pilot from Earth, uses his exceptional piloting skills to drive the humanoid mobile weapon “Striker” as a mercenary. On the battlefield, he is a warrior, but when he gets off the plane, he is nothing more than a poor man from Earth. Will there ever be a day of rest for Terusei, who is being targeted (sexually) by the Vurds, who have a high s*x drive and physical ability?
