On leave, special intelligence operative Remina is suddenly attacked by soldiers led by Colonel Kernel. Though she dodges the initial strike, the colonel's surprised gaze locks onto her exposed nipple, visible through her torn bikini. Remina returns to the lab to perform body maintenance—she is, in fact, a custom-made cyborg warrior assigned to covert missions. Infiltrating enemy territory, Remina is captured by mutant soldiers and subjected to brutal torture. Despite her purely mechanical heart, the soldiers exploit her body's vulnerabilities, forcing human-like reactions from her cold, stoic frame. Though she tries to remain detached, her body betrays her as she falls completely under the mutant soldier's control, driven into humiliating submission. "I absolutely must not lose," she repeats to herself—but what awaits her beyond that resolve... BAD END
