YU-GI-OH! ZEXAL

The Duel between Yuma and Ryoga comes to its conclusion. In order to take down "Leviathan Dragon", Yuma obtains a "Number" monster of his own, "Utopia".

Astral's been unable to leave since Yuma Dueled Shark, so, despite his reluctance, he's begun living with Yuma. At an inconvenient time, Akari Tsukumo has trouble when her PC she uses as a stay-at-home reporter crashes. When her big scoop is deleted as a result of a system down the city suffered, she orders Yuma to find an alternate scoop she can use for another manuscript. When Yuma goes into town, the traffic lights go nuts, causing downtown to fall into chaos. Yuma looks for the criminal who spread the computer virus that caused all this chaos.

Yuma challenges Professor Kitano, who is behind it all. Professor Kitano notes that each time he reduces his opponent's Life Points with "Electronic Computer-Beast Tera Byte" Astral's body weakens, causing him to slowly vanish! To make things worse, the Explosive Virus Time Bomb Ukyo has set is slowly reaching its countdown.

A strange shadow approaches Yuma, which turns out to be Tokunosuke Omoteura, a classmate of Yuma's known for his duplicitous tongue. In the morning, Yuma was reprimanded for a prank he pulled in front of the whole class that he has no memory of causing. As a result, he's been cut off from every one else. Tokunosuke gently says "Let's Duel". With "Baby Tragon" his new Xyz Monster, Yuma might enjoy this duel, but Tokunosuke seems to be planning something.

Tokunosuke steals Yuma's "Utopia", causing Astral to vanish. Tokunosuke had wanted the great power of Numbers, and Yuma tries to Summon "Leviathan Dragon" to fight back, but Tokunosuke's Trap Card takes even that away. When Yuma is pushed into a corner with his field, an unexpected monster will become the Trump Card of the Duel.

After having been around a while and having to work with Yuma, Astral's been fascinated by a TV Show Hero named "Different Dimension ESPer Robin". For some reason, Astral feels close and similar to this Robin from an alternate universe. One day, pictures show up with Robin in a fight downtown! Yuma, prodded by Astral, goes with Kotori to where the autographs were taken and meets Robin's actor, a kid named Fuya! But Fuya is a timid boy who doesn't resemble the Robin they all admire in the slightest.

The mysterious person posing as Robin around town was Fuya. Under the intolerable strain of being a hero, Fuya's heart has been dyed in darkness. Yuma challenges him to a Duel to save his soul. Robin, however, possesses "Number 83: Galaxy Queen". With it, he proceeds to summon one character after another from the TV Show. At first, Yuma and Astral were amused by this, but due to Galaxy Queen's almighty Monster Effect, they quickly grow impatient. To make things worse, Galaxy Queen, who currently possesses Robin, has taken on the appearance of Fuya's mother.

A suspicious shadow is trailing Yuma. It seems someone has been after Yuma, and their identity is the unassuming girl Cat-chan from Yuma's class. Yuma and Kotori fall into Cat-chan's trap. To rescue Kotori, he's going to have to Duel. Astral is cautious of the strange vibes he's getting from Cat-chan, especially with the strategy of her "Transforming Cat Deck"!

Yuma is reminded that his victories in his current Duels are due to Astral's help. To prove his skills, he fights Shark once more. Though Shark doesn't care to Duel again, he finally agrees when he finally reaches the end of his rope due to Yuma's constant following him around. The Duel of these two begins. Can Yuma win against Shark, who has no "Number" cards, when he himself declares he won't use his "Number" cards or require the aid of Astral!?

After his Duel with Shark, Yuma Duels Tetsuo Takeda without "Numbers" and loses twenty times in a row, with Tetsuo angry because Yuma lied about not using the "Numbers" against Shark. Yuma is scolded by Astral on his immaturity. On the other hand, Shark returns to "his place" where he gets involved in criminal company. Yuma, who knew what was going on with Shark, challenges the two strongest thugs: Rikuo and Kaio, to what Shark proposes to be a 2 on 2 "Tag-Team Duel".

Yuma finds himself pinned down by the overwhelming power of "Number 61: Volcasaurus". To protect their precious remaining Life Points, he defends Shark at his own expense. When their opponents summon their second Number monster at that point, Astral becomes aware of the hidden mysteries underlying the Duel. In a last-ditch effort, Shark notices Yuma's passion and entrusts him with 1 card that could turn the whole Duel around!
