The story takes place in a blank space created by scientists. Because the technology at that time was not developed enough to stabilize this space, disaster phenomena such as distortion and collapse often occur in the space. It can be said to be very dangerous. There are no living things in the space. Scientists buried large tracts of resources for human life there. Then, because of the frequent abnormalities in the space, the resource organization there was disrupted and mutated into incredible shapes. As for what kind of space it has become, the scientist does not know what it has become. He cannot detect the situation inside.
A scientist raised a rabbit. One day, the rabbit accidentally jumped into space and escaped. Although it was only trapped in there for an hour, three months had passed in the real world when it escaped. Moreover, the rabbit had a more developed mind than a human, and its body shape did not change at all, but it already had the ability to speak. The scientist wondered whether the mutation of the resource only changed the inner part, not the body shape.
The story of the scientist ends here, followed by Rabbit, who secretly mastered and developed all the scientists' technologies within a year, successfully created a portal to the empty space, and sent a letter to the chosen children.
