Overview: Because of a defect in their car, Ken and Jinpei have a breakdown in the desert. A young girl named Julia takes them in her car. She tells them that she's on her way to the harbor to meet her older brother Jeff, who works as a secret guardsman at the ISO. But the three of them are attacked in the harbor by the Black Raven mecha corps and Julia ends up heavily injured. Governor X is searching for a new core element, Hypernium 600, which is said to be 600 times stronger than the old core element, Platonium. He starts blindly attacking the cities surrounding the ISO secret hangar in the Abata desert, with his raven mechas. Jeff learns that the next target for the attack is the city of Kinzu. The hospital that his younger sister has been taken to is located in this city. In order to hand over the Hypernium 600 to the enemy and save his sister, he goes to steal it. Ken goes to stop Jeff and to reclaim the Hypernium. Meanwhile, Joe and the rest of the team go to the enemy base with the God Phoenix. On their way there, they encounter the raven mechas which unite and form one huge bird, then attach themselves to the God Phoenix. Using "Bird Diving", the Ninja Team gets rid of the ravens attached to the hull, and destroy the enemy base with a missile. Ken forgives Jeff for his fault, and Julia stays alive.
