The female lead falls into Spandexer Moon Angel Aya Shiomi SPSF-50

Contra, a Makina alien previously defeated by the Moon Angel after demonstrating her inferior strength, activates her newly developed Spandik Killer in revenge! Initially, she successfully repels the Killer, which is about 50% complete, but inhales uranium gas—a weakness pointed out by the warriors—resulting in a loss of freedom?! Under attacks from the Killer and warriors, the Moon Angel gradually loses energy. Furthermore, the Killer continuously increases its power during the battle, displaying strength surpassing that of the Moon Angel! The defeated Moon Angel is captured alive, and Contra humiliates her in the name of revenge... Then, Contra, as the only hope, is sent back after her energy is taken away. Although they regain their strength and fight again... [BAD END]
