Story
In a city in the near future, Heartland City, kids and adults enjoy Augmented Reality Duels. Augmented Reality Duels are Duels that use Duel Gazers and D-Pads, which when the two are used together, whether on the ground or in the sky, cause monsters to erupt from buildings and fight each other. The hero is Yuma Tsukumo. At a beginner level, he's a champion at absolutely losing. Due to a chain of events, Yuma ends up challenging the number one delinquent at his school, Reginald. His destiny is changed by a bizarre door he's seen in his dreams. When Yuma unlocks this sealed door, countless lights fly from it and escape. And when Yuma comes to, he sees the mysterious entity, Astral, who came from a parallel universe, standing before him. In order to regain Astral's lost memories, the flying lights from the door that have turned into the 99 "Numbers" cards, these two must work together. A series of mysterious and powerful rivals begin to appear before Yuma and Astral including a young boy named Kite Tenjo, revenge-seeking Vetrix and the maniacal Dr. Faker.
