In a world where humans have vanished, the remaining androids and robots lived among the ruins of the scrapyard. One day, a screw-type android named "Neshiko," while searching for an energy source, discovered a spherical cold-sleep device buried deep underground. Inside, a human girl lay sleeping. The robots, seeing a human for the first time, were astonished. Thus began a life in the scrapyard with robots who knew nothing of humans.
