The Spaceship that Doesn't Respond - S2.E18

A spaceship is being repaired by Jun. Jinpei releases a safety button because he is threatened by a gun, causing the spaceship to take off. The robot threatening Jinpei turns out to be a girl who introduces herself as Sachiko. Sachiko wants to meet her father, Tetsutaro Arimura, who works as research head at the Earth Investigation Station Moa. Following her wish, the ship makes a forced landing at the space station. But no one is there. While searching for Arimura, they coincidentally run into Galactor and get into a difficult situation. Galactor's goal is to steal data tapes of the Mantle energy and occupy the station. Using the two as hostages, they rob the Mantle energy data from Arimura. But the Science Ninja Team quickly arrives to rescue Jinpei and forces Galactor to retreat by shooting the artificial gravity device.
