Jun is attacked by a group of bikers. Koji saves her, he is a former race champion and Jun's friend from childhood.
Now he has become the commander of a Black Bird squad and is on the way to blow up the missile base of a certain country. When he wants to install the time bomb, the figure of Jun, the way he encountered her, crosses his mind. Without installing the time bomb, he runs away from the base. Jun sees his figure and reports to Nambu. She disagrees vehemently however when her comrades voice the opinion that Koji is a Galactor.
Koji, who didn't fulfill his task, is ordered by Katse to assasinate the President during a bike race which the President will be watching.
Jun goes to that race, in which Koji participates, only very reluctantly. But she agrees when Ken says that they will try to save him if possible. Koji's attempt to assasinate the President is foiled by Joe's sharpshooting and ends up in failure.
Koji seeks refuge in the officers' mansion. Jun follows him and sees how Koji gets orders from Katse. Koji notices Jun as well.
The bikes of the Black Bird squad transform and unite into a snake-shaped mecha which starts to attack the God Phoenix. In order to defeat the mecha, Jun presses the launch button for the missiles. When Koji is defeated by the Science Ninja Team, he decides that this is the punishment for his own crimes.
