Musashi visits the Kabushige Islands with mixed emotions. The Tech Thunder III he drives carries a new powerful anesthetic bomb, Dream. The purpose of this trip is to conduct experiments on the monsters that he has protected before. Just when Musashi is about to tell Chishan the purpose of this trip, the mad Golmedi Beta appears. The elite team launches a laser net at Golmedi Beta, but it is absorbed by it. What is the secret of its continuous strengthening by absorbing energy?
