The Saint of Braves Baan Gaan

The series takes place in an alternate universe where evil forces aim to conquer the game's alternate Brave multiverse. Astral, the leader of the Brave Saints, and Grandark, the leader of Brave Saga's villains, are the holy and unholy souls of this universe, whose consciousnesses are bound to its very forces, meaning both will perish if great harm is brought to one of them. Astral sends her Brave Saints, digital spirits, to Earth to possess toy robot fighters and stop the forces of evil. One of these spirits, known as Burn, befriends 5th grader Shunpei Serizawa, who is believed to possess a "holy heart."

In Brave Saga 2, GaoGaiGar, along with new original characters, join the team as the Braves fight trans-dimensional demons known as the Asmodians. Brave Saga New Chapter: Astaria is essentially a spin-off of the Brave Saga games, taking place in the distant fictional land of Astaria. Mechanics from both The Saint of Braves Baan Gaan and from the TV shows reappear in the game.
