Assigned to the coveted spaceship Planet, beautiful scientist Nanami Nanase holds a Ph.D. in space biology. Fulfilling her dream of working alongside the legendary Space Kernel, on her first day she receives a transmission from Alpha Star—an unexpected encounter with alien life. The Alpha Star beings feign friendship but secretly use Nanami's body to experiment on human physiology. During the process, physical contact triggers unexpected sexual arousal within her. However, this arousal generates electrical energy—an essential power source for the aliens. Using a vibrating device, the Alpha Star beings stimulate Nanami's groin to harvest energy. Her comrades attempt a rescue but are defeated, brainwashed, and forced to assist in the energy extraction. Nanami's body is further restrained by countless penetrating holes as grotesque hands grope and manipulate her lewdly. When her teammates finally regain consciousness and repel the aliens, they succumb to perverse desires and end up violating Nanami themselves.
