Aboard the ship, The Chief explains that when hit with Birdronic waves, they will turn into Choujin Sentai. Immediately after Tendou Ryu's conversion into a Jetman, the enemy Vyram attack. Radiguet, the leader of the Vyram, announces that they have conquered other detentions and now plan to conquer the 3rd dimension. During this attack, Ryu loses his girlfriend Rie through a hole in the ship. The Birdronic wave machine shatters and the remaining 4 waves are sent down to Earth at random.
