The Seal Science Ninja Team in the Night Fog

A secret mining factory of the ISO is attacked and the island on which the factory is located is besieged by Galactor. In the mine, an ore containing more energy than uranium is being mined. If this ore were to fall into Galactor's hands, the consequences would be catastrophic. Opposing the ISO which demands the protection of the ore, Nambu insists that saving the people has priority. The Science Ninja Team and a group of transport ships head towards the seal island where the factory is located. The island is hidden all year in a fog, and also Galactor is just standing there without being able to intervene. One group sneaks in, ducking under a Galactor attack, and gets near the island. They send G-4 to the island and he decides to get the workers out of there to the ships. He is able to hide them in a group of seals that had been surprised by a Galactor attack and are seeking shelter in the sea. The plan succeeds and the workers are saved, but the ore is stolen by Galactor's mecha. Also the fact that the workers could escape gets to be known. The transport ships are attacked and the workers taken as hostages. Katse threatens to kill the workers if the Science Ninja Team doesn't show itself. The Science Ninja Team appears in the dome atop the God Phoenix, but the moment the guns aim at them, the baby seal Jinpei took with him jumps into the sea. The Galactor members are distracted for a short moment by that noise and the Science Ninja Team seizes the opportunity to launch a counter-offensive. They succeed in reclaiming the ore from the mecha.
