Space Squadron Star Ranger's leader, Seira Akagi, learns from a space information dealer that her father, Go Akagi, is participating in Ragoo's underground pro-wrestling event. She heads alone to the secret wrestling venue. There, she discovers her father—whom she believed to be dead—alive but revealed to be under Ragoo's control. Transforming into Red, Seira attempts to rescue her father but is intercepted by the high-ranking monster Gorarin. During the battle, Go, still influenced by Ragoo, ends up aiding Gorarin. As a result, Red loses her powers, is captured, and subjected to intense interrogation at Ragoo's hideout. Weakened, Red is brought to the underground wrestling arena where her father awaits. From here, the fierce battle truly begins... BAD END
