In 20XX, Earth is dominated by AI, and the battle between humanity's resistance force, "The Resistance," and the AI reaches its peak. During a mission, the Resistance squad leader encounters and successfully captures a female cyborg model sent for reconnaissance—T-77, known as Nana. Nana is a cutting-edge model equipped with a high-performance AI, making her resistant to ordinary physical damage. As a result, the squad leader devises a bold plan to destroy her artificial brain from within, using tickling, vibrators, and electric massagers as methods of torment. While enduring the torture, Nana displays expressions of fear and humiliation. Her suffering creates a shocking scene that blurs the boundary between AI and humanity.
