Hyper Stella is cornered by the Pickel Aliens, who plot to destroy Earth for their own greed, and their assassin, the giant robot Diguld G. Diguld G attacks by transforming its arms into various weapons. Hyper Stella loses her power due to energy absorption from her timer and barely escapes by reverting to her human form, Seiko. After returning to base as Seiko, she is pursued by the Pickel Aliens, who make her body hypersensitive, causing her to climax repeatedly until she faints. The Pickel Aliens further defile Seiko by disguising themselves as her fellow squad members, leading her to climax again and again. However, Seiko uses her wits to somehow fight back on equal terms?! They clash once more in a giant battle, but Hyper Stella is severely exhausted and falls to the wand massager arm and vibrator arm, and finally, her chest timer is... [BAD END]
