This series takes place in 199X on the Earth Ship, the command center of an international defence agency called Sky Force, the guardians of peace on Earth. In the ship, scientists have developed “Birdonic Waves”, a newly developed technology which gives the subject superhuman abilities. Experiments called “J-Project” were successful. Aya Odagiri, the director of the project, chooses five elite Sky Force officials from Earth to use this technology. Ryu Tendo, oneof the Sky Force officers, is successfully exposed to the Birdonic Waves, making him the first Jetman, the Red Hawk.
However, the Earth Ship is suddenly attacked by Vyram, an evil outer-dimensional organization bent on inter-dimensional domination. They successfully destroy the ship, apparently killing Ryu’s lover and fellow candidate member Rie. In the chaos, the remaining Birdonic Waves for the other four officials become scattered on Earth, hitting four civilians. Odagiri and Tendō successfully escape and begin searching on Earth for the four remaining Jetman, training them to aid them in stopping Vyram’s plans of conquering their dimension.
