Back through space to a world laid waste by nuclear war, Amamiku and her parents Ryu and Uri, return. They carry the seeds that hold the genetic code of the planet and can be used for its rebirth. As they land in one of the less polluted oceans of the planet, both Ryu and Uri are contaminated by the earth's radiation. They leave their daughter, Amamiku, asleep in stasis, charging her with the task of restoring the earth. 90 years later, the now 14 year-old Amamiku lives underwater protected from the radioactive atmosphere above, and impatiently waits for the earth to be ready for the seeds to germinate. With only the ship's computer, Mayzamik, and the robot Pyron, for company, Amamiku has been alone since she woke ten years ago. But when her existence is discovered, it sparks a frantic race between the remains of humanity struggling for survival, and the disembodied brain, Glyptofane. This fanatic being, who sees mankind as a plague, has programmed his robotic army to destroy them. Can Amamiku overcome this overwhelming threat, so she can complete her parent's work and make the earth fertile once again...?
