The scientist Demon tries to sell his own invention to Galactor by using it to attack a cargo plane, which carries goods for those in need. He hates Nambu, who has been battling him for a position in the ISO as a schoolmate. For leaking information on the mecha and thus luring out Nambu, Katse makes it a condition that the true faces of the Science Ninja Team should be revealed.
Nambu agrees to Demon's invitation and goes out to an airfield. Demon notices that the Science Ninja Team secretly acts as Nambu's bodyguards. He takes a picture of the figures with a small camera hidden in his eyepatch, then throws a small bomb. The Science Ninja Team understands that their uncovered faces have been photographed and they lose their courage.
Soon another cargo plane takes off and the God Phoenix accompanies it as bodyguard. Ken tells them to fly into the spider net of the appearing mecha. Through the information received from Demon, the G-4 is equipped with an electronic membrane and can cut through the threads with its buzzsaw, thus enabling the God Phoenix to fly into the mecha.
Demon points his gun at the Science Ninja Team. The bullet hits Jun's bracelet and the transformation is undone. Demon points his camera at Jun but Ken and Joe appear in front of him, extending their cpaes and protecting Jun.
The Science Ninja Team approaches Demon. He resigns and when he hands over the photo, he presses the switch for the self-destruct mechanism.
After escaping, Ken and the others look at the photo in the God Phoenix. Voices with relieved laughter are heard. In the photo, only the legs of five persons about to fly away can be seen.
