Summary . Hart Tenjo opens his eyes , as his brother , Kite , offers him a cup of hot chocolate . They are at a small cabin with a tree next to it in the middle of a lush grassland . Hart is in a bed , probably still recovering from his collapse during Kite and Yuma ' s first Duel . They talk , but the scenery they are in is revealed to be a hologram , as Mr . Heartland stops it and comes up . Heartland asks Hart if he ' s ready for another round , but Kite heavily replies he shouldn ' t . However , Hart himself gets up from his bed and goes with Mr . Heartland , who asks Kite to continue his Hunting . Yuma Tsukumo , surprised , falls from his hammock , as Astral told him about the ship in the Emperor ' s Key . Astral tells Yuma that the ship looks like a giant puzzle that can only be solved by gathering the " Number s " . Meanwhile , Kite enters a room whose walls appear to be giant computer chips . He heads to the big computer frame in the middle , where Orbital 7 is . Kite calls Orbital ' s name , but the latter appears to be sleeping , being shocked when woken that he got caught sleeping on the job . Kite makes a comment about it , and then asks if Orbital knows a new Number . Orbital , panicked as usually , boots up the computer quickly . After another comment from Kite and another shocked expression from Orbital , the latter shows the former information about Yuma , and about his key . He then leaves on his Hunt . At his school , Yuma appears to be late , quickly running through the hallways . Reginald Kastle sees it and is amused by it . Mr . Kay notices it , and mentions how much Shark changed after meeting Yuma . However , Shark keeps his cool . At the pool , Yuma and his classmate Caswell get into an argument , as Yuma is wearing his Key around his neck and Caswell doesn ' t agree with it , saying it ' s dangerous . Though Yuma says it isn ' t , Caswell insists . Tori tries to make Yuma realise why it ' s dangerous , saying Yuma hurt his own head with the pendant . However , since that never happened , Yuma asks who really hurt their head . Caswell takes his cap off , revealing a bandage on his head . Yuma decides to go to his locker and put the Key there , after all . He wonders if Astral will be fine , but he decides to leave . At the school ' s roof , Shark looks at a card , but sees a trash can move underneath him . It ' s Orbital 7 , who sneaks into the locker room . Inside the Emperor ' s Key , Astral looks at his collected Numbers , and remembers the vision he saw when " " was defeated , wondering what it meant . Orbital uses an infrared ray to look through the lockers ' doors , and spots the key , opening the locker . He takes , but Shark grabs it out of his claw . It immediately panics and Shark kicks Orbital against a wall . ( In the dub , right before Shark kicks Orbital , it blacks out with some yellow lines until Orbital 7 is seen against the lockers . ) Orbital , however , doesn ' t seem to be amused by it and transforms into a skull - like robot with a drill equipped . He attacks Shark , but he quickly ducks away and runs away from the lockers , with Orbital , who broke through a wall , pursuing him . Inside the key , the gears stop spinning , and the wall with the small pillars pointing out with the captured Numbers on it retracts , and Astral wonders what ' s happening outside . Once outside , Orbital 7 surprises Shark , and is about to hit him with his drill . However , Kite orders him to stop , and asks Shark to hand over the key . They converse , and Shark reveals he knows about the Numbers . Shark makes Kite challenge him to a Duel , with Shark ' s " Numbers " , which Kite thinks Shark has , and the Emperor ' s Key on stake . Flashing back to him and Yuma ' s Duel with Scorch and Chills , and Shark accepts . Shark tosses his D - Pad into the sky , and Kite performs Photon Transformation , changing his coat from dark to white . Shark readies his Duel disk , and Kite ' s disk lands on his arm ( shot by Orbital 7 ) . Shark puts on his D - Gazer , and Kite ' s left eye is surrounded by the blue lines , turning his iris red , and the two start their Duel . The girls look frightened outside of the big hole in the wall , and the boys are in their ravaged lockers , where Yuma finds out his Key is gone . At the Duel Shark takes the first turn , drawing , and determining Kite ' s possible strategies , as he as a Numbers Hunter must have " Numbers " . He activates " Shark Lair " , discarding " Big Jaws " , and using its effect to summon " Shocktopus " , and ends his turn by setting a card . Kite makes his move , using " Polymerization " . He explains the concept of monster fusion and fuses his two " Photon Lizards " to Fusion Summon " Twin Photon Lizard " . As its ATK is higher than Shark ' s discarded " Big Jaws " , " Shark Lair " is destroyed , and Kite declares battle between " Twin Photon " and " Shocktopus " . Shark uses the effect of " Shocktopus " , but Kite simply activates the effect of " Twin Photon " to Tribute it and summon the Fusion Material Monsters from the Graveyard . Shark smiles as he was waiting for an Xyz Summon . Kite then overlays the " Lizards " to Xyz Summon " " . Shark is surprised by the 3000 ATK , which is a lot for a Rank 3 Xyz Monster with only 2 materials . Grabbing his chance , Shark uses " Splash Capture " to take " Acid Golem " away . Orbital 7 panics , but Kite tells him to quiet down . Kite uses " Forced Release " to take away Overlay Units from " Acid Golem " . Shark says that even without Overlay Units , the " Golem " still has 3000 ATK . Shark now understands he made mistake to take " Acid Golem " away , as he takes 2000 points of damage as he doesn ' t have any Overlay Units on " Acid Golem " to remove , as explained by Kite . Shark doesn ' t give up and tries to declare battle , but Kite explains " Acid Golem " can ' t attack without Overlay Units either . Shark looks discouraged , as the card he took is causing him to lose . However , looking at the Emperor ' s Key , he ' s reminded that he ' s fighting for Yuma . Kite draws , and using a combo of " Photon Sublimation " , and " Photon Thrasher " and " Photon Crusher " , he surprises Shark by Special Summoning his " Galaxy - Eyes Photon Dragon " , which attacks " Acid Golem " . Yuma and his friends are looking for Astral and the Key , but inside the Key , Astral ' s " Numbers " circle around him and he hears a voice , mentioning the ZEXAL power . Because " Acid Golem " doesn ' t have any Overlay Units , it destroys itself and takes away 2000 of its controller ' s LP , knocking Shark from 1200 down to 0 , making him lose . Shark gets knocked over , and apologizes to Yuma , as he couldn ' t save the Key , and Kite proceeds to use his Photon Hand to steal Shark ' s soul , and " Numbers " he might have . Kite attempts to take a " Number " from Shark ' s soul , but there is none . Yuma and his friends arrive , with Yuma recognizing Kite . Orbtial 7 informs Kite that Photon Transformation is already at 85 % , meaning he can ' t Duel again right now . Kite takes the Key , and flies away with Orbital who transformed into his glider - like form . Yuma rushes to the edge of the building , and screams out , " Astral " . ( In the dub , Yuma calls for Kite to come back with his key . ) Featured Duel : Reginald " Shark " Kastle vs . Kite Tenjo . Turn 1 : Shark Shark draws . He then activate s " Shark Lair " to send " Big Jaws " from his hand to the Graveyard ( as it ' s a Fish - Type monster ) in order to prevent monsters Kite control s with less than or equal ATK to the sent monster from attack ing . Shark Normal Summon s " Shocktopus " ( 4 / 1600 / 800 ) in Attack Position and Set s a card . Turn 2 : Kite Kite draws " Polymerization " and subsequently activates it to fuse the two " Photon Lizards " in his hand in order to Fusion Summon " Twin Photon Lizard " ( 6 / 2400 / 1000 ) in Attack Position . " Twin Photon Lizard " attack s and destroy s " Shocktopus " ( Shark : 4000 → 3200 LP ) . Since " Shocktopus " was destroyed by battle and sent to the Graveyard , Shark activates its effect to equip itself to " Twin Photon Lizard " ( as it was the monster that destroyed it ) and reduce its ATK to 0 ( " Twin Photon " : 2400 → 0 ATK ) and prevent it from changing its battle position . Kite activates the effect of " Twin Photon Lizard " to Tribute itself and revive his two " Photon Lizards " ( 3 / 900 / 1200 ) in Attack Position ( as the " Photon Lizards " were the Fusion Material Monsters for the Fusion Summon of " Twin Photon Lizard " . Kite overlays his two " Photon Lizards " in order to Xyz Summon " " ( 3 / 3000 / 3000 , ORU : 2 ) in Attack Position . As his opponent Xyz Summoned , Shark activates his face - down " Splash Capture " to banish " Big Jaws " and " Shocktopus " ( as they are both Fish - type monsters ) and take control of " Acid Golem of Destruction " . Kite activates " Forced Release " to detach all Overlay Units from " Acid Golem of Destruction " ( " Acid Golem " : 2 → 0 ORU ) . He then Sets a card . Turn 3 : Shark Shark draws . During the Standby Phase , Shark takes 2000 damage from the second effect of " Acid Golem of Destruction " as the latter had no Overlay Units for Shark to detach for this effect ( Shark : 3200 → 1200 LP ) . He attempts to use " Acid Golem of Destruction " to attack directly , but Kite explains that " Acid Golem of Destruction " may not attack if it has no Overlay Units . Shark Sets a card ( " Life Regeneration " ) . He intends to activate " Life Regeneration " during his next turn to avoid taking damage from the effect of " Acid Golem of Destruction " and gain an equal amount of Life Points instead . Turn 4 : Kite Kite draws . He then activates " Photon Sublimation " to banish his two " Photon Lizards " from his Graveyard ( as they are both " Photon " monsters ) and draw two cards . As he controls no monsters , Kite Special Summons " Photon Thrasher " ( 4 / 2100 / 0 ) from his his hand in Attack Position via its own effect . He then Normal Summons " Photon Crusher " ( 4 / 2000 / 0 ) in Attack Position . Kite then Tributes " Photon Thrasher " and " Photon Crusher " in order to Special Summon " Galaxy - Eyes Photon Dragon " ( 8 / 3000 / 2500 ) from his hand in Attack Position via its own effect ( as the Tributed monsters had at least 2000 ATK . " Galaxy - Eyes Photon Dragon " attacks " Acid Golem of Destruction " . As " Acid Golem of Destruction " was attacked while it had no Overlay Units , its final effect destroys itself before the battle and inflicts 2000 damage to Shark ( Shark : 1200 → 0 LP ) .
