Three thousand years ago, the Space Pirates Barban invaded Earth. The Star Beasts and the first Gingamen, warriors of the Ginga Forest, fought them with a mystical power known as Earth and eventually imprisoned them. The Ginga people later cloaked their forest within marked boundaries and passed on the duty of the Ginga warriors through generations. In the present day, Hyuuga, Hayate, Gouki, Hikaru and Saya are chosen as the 133rd warriors of the Star Beast Swords. (wikipedia)
