Synopsis

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. In the present day, Hyuuga, Hayate, Gouki, Hikaru and Saya are chosen as the 133rd warriors of the Star Beast Swords. After an earthquake breaks the seal that held Barban is destroyed, Barban attacks them to prevent the birth of the new Gingamen. During the battle, Hyuuga is swallowed into a crack in the ground created by the Barban's leader, Captain Zahab. Enraged, Ryouma (Hyuuga's younger brother) activates his hidden Earth power and awakens the Ginga Braces. The Gingaman fight together with the Star Beasts against the Barban, who desire to revive the Demon Beast Daitanix, on whose corpse they built their castle.
