Lead by Commander Aya Odagiri who has selected five officials to be exposed to "Birdonic Waves" a newly developed technology that can give a human super abilities. Among the subjects to the project is Ryu Tendoh who is the first volunteer to be exposed to the Birdonic Waves and thus becomes the first nominated member of the newly established Jetman team. The other four subjects were about to be exposed to the same waves as Ryu did until the space center was attacked by the Vyram, an evil outer-dimensional organization bent on inter-dimensional domination. The Vyram successfully destroy the space center along with killing most of the humans on board. After the destruction, the remaining Birdonic Waves that were meant for the now dead four officials got scattered on the surface of the Earth. Hitting four different civilians who were going about their daily lives. Odagiri and Tendoh who had successfully escaped the doom space center soon began searching on Earth for the four remaining humans with Birdonic Waves in order to fully form the Jetman team. Forming the team will be no easy task as the four civilians had no prior training in military tactics and must learn to work together and look pass their personal problems if they are willing to save the Earth from the Vyram which was being lead by the cruel Count Radiguet.
