Story
About one thousand years into the future, civilization has been retrograded and humans are living dispersed within small communities. People in this era have a psychic power called "Juryoku" which materializes things they imagine. In the absence of advanced scientific technology, people are using this power as a major source of energy. One day, a girl called Saki, along with her friends, finds a small archive robot outside the town. It records the ancient history of humans.
