Kagaku ninja tai Gatchaman

A year earlier, the northern country Flanbel escaped from the rule of the Dictator General Somure. But Galactor, who instructs Somure, appears in the mansion of the Prime Minister and tells him that he either obeys or dies. By the demand of the governor, the Science Ninja Team sneaks in through the secret back door. On the peace memorial day, presents are distributed to the children by the governor. But the Suimusa group, which Jinpei met, have their presents stolen by children from the upper city quarter. That night during a patrol, the Science Ninja Team discovers that all the families which opened the presents are dead. They learn that the governor is a subordinate of Somure and has put poison gas into the presents. Meanwhile, the Suimusa group has gone to the celebration site in order to tear down the snow man to vent their anger. However, that snowman is the camouflage for Galactor's mecha. Mistaking the shapes of the Suimusa group for the Science Ninja Team, Galactor captures them. But they are saved by the Science Ninja Team who follow them and take them aboard the God Phoenix and escape. The mecha pursues them. In the interior are the governor and Somure. Burying the mecha together with Somure and the governor, the God Phoenix leaves. Inside, the Science Ninja Team says they want to make a present as replacement for the ones the Suimusa group missed. The Suimusa group replies that the best present was to have been able to fight alongside Gatchaman. The voices of the children echo "Justice will win for sure!"
