A team of demons cuts down numerous trees in the vicinity of Saotome's laboratory, causing the escape of thousands of bats. The small mammals are captured and an explosive device is grafted onto their bodies. Once released, the bats nestle in the spouts of Saotomè's laboratory, blocking the exit of the Getta devices. A robot demon attacks the laboratory and the Throws team watch helplessly as the structure is damaged. As the Getta Robot does not show up, the monster attacks the city, forcing the intervention of the heroes. Using a trained falcon, Benkei manages to make most of the bats escape from the ducts but a robot bat hypnotizes the flock which is led back to the laboratory. The falcon loses his life in the clash with the robot but the flying devices destroyed only the external part of the exits. Taking advantage of the situation, the Demon Robot returns to the assault and Lady Command can only try to buy time; the boys manage to take off despite the precarious conditions of the runway and, combined in Getta Robot, they eliminate the monster in a quick fight with the sword, also avenging Benkei's hawk.
