Wing Mask lead a corp of the Black Cross Army in developing a powerful wind-machine that can create hurricane-force winds up to 100 meters an hour, empowered by the Hurricane Diode they have developed. While the Gorengers find out about this from a fallen EAGLE spy, they soon discover that he has befriended a girl who has lost her balloon-selling father and has used balloons to bond with her, even if the equivalent to a hostage scenario. The Gorengers work to rescue the girl in order to close in on the Hurricane Diode, but Wing Mask captured Peggy, tortures her and holds her until Kaijo and Asuka come to her rescue.
