Ninety years ago, global nuclear war destroyed the Earth, leaving the seeds of hope for the future in the hands of young Amamiku. Now, in the present, Amamiku has awoken from her cryostasis into a strange underwater world. Her mission, as deemed by the holographic images of her long dead parents, is to use the seeds to revive Earth - but it won't be easy. Though a small selection of other humans are alive and willing to help her on her quest, others such as the evil floating brain creature Glyptofane want to prevent Earth's revival at all costs. The fate of the world lies in a young girl, her robotic companion, and a few brave souls; will she succeed?
