A large ring, said to allow an individual to create a utopia for themselves. It was a mystery whether it was a relic or some kind of foreshadowing. Then one day, in the year 2022, a spatial distortion suddenly appeared in Ginza, Tokyo, followed by a great earthquake. The world was left completely in ruins and the axis of the planet itself was in jeopardy. Apparently an alternate Earth, or a parallel world, had been created at the distortion.

The five females of the Plastic Memories retention agency were then sent to Earth to return these beautiful young women to their homes.
