Dan gets pulled into a future war he didn't ask for, armed with cards that work nothing like the ones he mastered. The entire show is built on that specific friction: he's the expert who suddenly has to be a novice again, learning Brave cards in real combat while people's lives depend on it. Kids watching this aren't just seeing card battles, they're watching someone prove themselves twice.

Two years after he helped save the world in Grand Rolo, Dan Bashin finds ordinary card battles dull and longs for stronger opponents. His chance comes when Mai Shinomiya offers to take him to the future. In the year 2650, humanity is being overrun by the Mazoku, a race of demons from another dimension. Dan joins the crew of The Beautiful Sophia and builds a deck around Brave, the newest type of card. Alongside the other light bearers, he must once again carry the fate of humanity, and failure would mean a reset of Earth's entire timeline.
