Synopsis
Battle Spirits: Brave follows Dan Bashin, a former hero who has become disillusioned with ordinary card battles.
He's given a chance to reignite his passion and prove his strength by traveling to a distant future.
In this future, humanity is on the brink of collapse, locked in a desperate war against a powerful alien race known as the Mazoku.
Dan, along with other "light bearers," must once again rise to the challenge, using new cards from the future to fight for humanity's survival.
He and his allies face a new conflict, where the fate of the world rests on their shoulders as they combat this overwhelming threat.
