Fumiko Sawazaki, a member of the Earth Science Special Forces, is suddenly summoned by her captain to the operations room. On the monitor appears a clear unidentified flying object emitting strange light. While gathering UFO-related intel around the city, Fumiko notices a mysterious shadowy figure that suddenly appears. She chases after it but quickly loses sight of the figure. However, she senses something approaching from behind. Suddenly, a life-sized Filanes Alien emerges behind her. The Filanes Alien warns Fumiko, "Don't interfere," then rapidly grows to giant size and begins destroying the city. As people scramble to evacuate, Fumiko calmly pulls out her transformation device and also grows giant. Her transformed form is Freya, an alien from outer space. Freya defeats the Filanes Alien, but feels a lingering unease at how easily the enemy was defeated, and heads back to base. Meanwhile, Fumiko hears the voice of the Filanes Alien, reacts to it, and is captured by its special abilities. Inside the alien's spaceship, Fumiko is subjected to a thorough bodily examination.
