In the vastness of space, there exists a being unknown to most people. It has no physical body and has wandered the galaxy for countless ages.
One day, it decides to land on a planet that catches its interest.
After arriving, the being realizes it needs a physical form — a body that will allow it to move freely without causing fear or panic among the planet's inhabitants. As it wanders across the world, it discovers a photograph of a model said to be from a place called China. Fascinated by the image, the being chooses to transform itself into the girl shown in the picture.
Soon after, she travels to Japan.
There, she witnesses a group of warriors gathering to battle a monster. She learns that they call themselves No.1 Sentai Gozyuger. From a distance, she simply watches the warriors fight, observing their strength and determination.
The next day, she realizes she needs a name to live among humans. After some thought, she chooses the name Hitomi Oga.
Hitomi lives in the Gozyuger universe for nearly a year before deciding to travel to another universe.
