The Super Beagle, transformed into a cyborg by the Devil Empire, attempts to escape from prison. She defeats soldiers and monsters one after another, eventually hiding in an old man's mansion whom she meets by chance. However, the Devil Empire's elite assassin, Black Vision, captures the old man and overwhelms Beagle in combat, dragging her into their grasp. She is taken to the Devil Empire's base to undergo brainwashing, but her strong will resists even their mind-control machine. Enraged by her defiance, Black Vision resolves to fully dominate her body and weakens her mental resistance through cruel methods. Her cybernetic body is stimulated with weak electric currents, soldiers' erect penises are forced into her, and a lust circuit is implanted into her abdomen, subjecting her to relentless pleasure. Driven higher by the lust circuit, Beagle becomes increasingly aroused, pushed repeatedly to the peak of ecstasy. Ultimately, she is completely consumed under the Devil Empire's control... BAD END
