Kagaku ninja tai Gatchaman

Gold bars are stolen from the vault of the World Bank. It is the deed of Galactor's Mini Robots. The Science Ninja Team get their instructions and start a search on the islands in the vicinity of the place where the gold bars seem to have been taken. Joe makes sure that Ken, Jun and Jinpei, in civilian wear, attract the enemy's attention and get taken off to the base. He proposes that if this is the headquarters, it should be destroyed right away. However, Nambu stops him by saying it's not the Science Ninja Team's duty to attack. Joe leaves a bored Ryu behind in the God Phoenix on the bottom of the sea and sneaks into the base in order to prepare for retaking of the gold bars. While Ken and the other create a lot of confusion in the interior of the base, Joe goes looking for the gold bars. He learns that a missile is about to be fired at the God Phoenix when it is detected by the surveillance cameras. He contacts Ryu in the God Phoenix, right away. Ryu, who is always merely on stand-by, is taking a nap, though manages to evade the missile by a hair's breadth. With Joe's guidance they store the stolen gold bars in the God Phoenix's interior. Ken and the others are contacted and escape from the base. The Galactor base and all its inhabitants are blown up because they didn't manage to prevent the gold bars being stolen back.
