"The Numbers War heats up as Yuma and the Numbers Club track down more of the powerful cards. Kaito's past comes into play as Yuma tries to find out why this expert duelist is seeking the Numbers Cards. A duel between Kaito and Yuma's old rival Shark may lead them all to a surprising alliance!"--Back cover.

"Kyoji Yagumo has maneuvered Yuma and Kaito into a duel for Haruto's life. Elsewhere, Luna approaches the Numbers club and enlists them to help her locate Haruto. With all the Numbers cards now in play in the massive Heartland Duel Arena, the final battle of the Numbers War is about to begin!"--Back cover.

In a futuristic city, augmented reality Duels are all the rage. Duelists, using devices called D-Gazers, can interact with their environment and their opponents as never before. With more awesome monsters and unbelievable cards, the future of Yu-Gi-Oh! starts right here! No one loves Dueling more than Yuma Tsukumo, but unfortunately for him, no one is worse at it! This isn't going to stop Yuma from trying though. When Yuma calls on the memory of his parents during the Duel, a strange being called Astral appears, and the encounter is the start of Yuma's amazing Duel journey!" -- p. [4].

Although Yuma Tsukuma loves Yu-gi-Oh! duelling, he is not very good at it, but during a match, a memory of his parents for some reason draws a strange being called Astral to him and Yuma embarks on an amazing duelling journey.
