It first aired in Japan on October 24 , 2011 , and aired in the United States on September 8 , 2012 . Summary . Yuma and Tori are running through a construction site . Tori questions him why they ' re there . ( In the dub , they are rushing to a movie premiere , and Yuma wants to cut through the site as a shortcut . ) Astral asks what it is where they are . When Tori and Yuma are arguing over why they ' re there , above them , the iron beams break , and fall down . Yuma rushes to Tori , when a shovel turns around and knocks the beams away . Yuma and Tori run as the machine rolls on right behind them . By jumping over an iron beam formation , the two manage to get into safety as the shovel crashes against the formation , shattering the glass at the front . They here a shout from it , and a little boy jumps out of it , trips , and falls . He sits down and moans about what happened , and Yuma asks who he is , while Astral comes closer by . Apparently feeling insulted , the boy introduces himself as Cody ( or Shobee in the Japanese Version ) , referring to himself as ore - sama ( Japanese Version only ) ( a boastful way to refer to oneself in Japanese ) . Tori introduces herself and Yuma to him . She kindly thanks Cody for saving them , and the latter has to blush , but replies strongly . Astral looks interested at a bolt . Yuma is amazed by a huge construction truck , and Cody explains what it is for . They then look at a crane , and Astral is intrigued by it . They talk about what they find of it . Cody mentions the World Duel Carnival , and Yuma tells him he is participating as well . They start arguing about whose Deck has the most power , and decide to find out with a duel . Yuma starts his dueling ritual , and their duel starts . Cody starts the duel quickly by calling forth two of his Heavy Industry cards , Jumbo Drill , and Road Roller . Yuma counters using his Gagaga Magician . Astral questions him if he thought of Cody ' s monsters ATK and DEF being 2100 . Yuma , embarrassed , is told by Astral to use the Equip Spell Card he ' s holding . Following Astral ' s advice , he equips " Gagaga Magician " with Bound Wand and activating " Gagaga " ' s effect to raise its Level to 8 and thus its attack points to 2300 . However , Cody ' s Trap Card turns the odds in the battle and destroys " Gagaga Magician , " also knocking Yuma ' s LP down to 3200 . Yuma is able to bring it back from the Graveyard with the effect of " Bound Wand , " so he won ' t be wide open for direct attacks from Cody ' s monsters , summoning it in Defense Position on Astral ' s advice to prevent as much as possible Battle Damage next turn . Cody remarks that this way Yuma won ' t defeat his " power " . He draws and summons Strong Shovel Excavator in attack position , and the ATK of " Jumbo Drill " increases by 300 since there ' s now another Heavy Industry monster on his field . He has " Strong Shovel " attack " Gagaga Magician , " but Yuma responds with Half Unbreak , so " Gagaga " can ' t be destroyed by battle this turn and damage to Yuma from battles involving it is halved . " Drill Jumbo " then attacks , which inflicts piercing damage . This damage is , however , halved by Half Unbreak , although Yuma ' s LP are still decreased to 2500 . Although laughing at first , Cody gets embarrassed when his " Jumbo Drill " switches to defense position and can ' t be changed back until his next End Phase by other means then a card effect . Astral tells Yuma that this is their chance . Yuma confirms , and switches " Gagaga " to attack position and summons Mystical Donator . He uses its effect , lowering its attack to 0 and increasing " Gagaga " ' s by 800 to 2300 . He attacks and destroys " Strong Shovel " decreasing Cody ' s LP to 3500 and the ATK of " Jumbo Drill " by 300 . Yuma sets a card and ends his turn , and " Gagaga Magician " and " Mystical Donator " regain their original attack power . Yuma remarks his " power " to which Astral makes a remark , which seems to stop Yuma ' s boasting . Cody complains about Yuma ' s remark . He flashes back to his younger days , in which he spent lots of time at a construction site , and was fascinated by the machines . He then tells his reason for participating in the WDC . Cody begins his turn , using a powerful combo to regain his lost " Strong Shovel " and make his 3 monsters Level 5 , and overlays them to Xyz Summon Digvorzhak , King of Heavy Industry , a massive construction machine with 3200 Attack Points . Cody introduces it to Yuma , and Astral tells Yuma how powerful this card is . He consumes an Overlay Unit from it to send the top three cards of Yuma ' s Deck to the Graveyard , which are Blustering Winds , Gogogo Golem and Goblindbergh . Since there were 2 monsters among the sent cards , two monsters on Yuma ' s field can be destroyed , so both " Mystical Donator " and " Gagaga Magician " are crushed . " Digvorzhak " starts making noise when Cody declares a direct attack with it , so Yuma can ' t hear Astral . By moving his hand , however , Astral manages to tell Yuma to activate the set Trap Card Small Resistance . By using " Small Resistance " ' s effect , Yuma is able to lower " Digvorzhak " ' s attack points to 2400 , surviving with 100 LP . Discouraged , Yuma looks at his hand . However , Astral uses what he learned about the construction site the last while , to tell Yuma " Digvorzhak " can be defeated . Yuma asks why he can hear Astral better than before which he says that they can speak telepathically . He compared it to the game of soccer he learned about during their last duel , he compares a duel to a construction . Yuma understands , and draws , while Cody asks if he already surrendered to his " power " . Yuma summons Kurivolt , and uses its effect to take away " Digvorzhak " ' s Overlay Units , and summon two Kurivolt Token s to his side of the field , shocking Cody , who quickly recovers and says the three little monsters are no threat . Yuma , however , disagrees by playing Mini - Guts , tributing two Level 1 monsters in order to decrease " Digvorzhak " ' s attack points to 0 . Cody first laughs at the Kurivolt Tokens attaching themselves to Digvorzhak , but all screws keeping it together soon fall out . He attacks it with " Kurivolt " , and the little creature shocks the huge machine , making it fall apart , destroying it and inflicting 300 points of damage . Using Mini - Guts ' second effect , Yuma deals Cody damage equal to " Digvorzhak " ' s ATK ( which is 3200 ) , thus depleting Cody ' s remaining 3200 LP to 0 , who is left in the smoke of the explosion . Cody asks Yuma how he was able to overcome his power , and Yuma explains , making Cody realize it ' s not the only way to win . Cody understands , and keeping his cool , tosses Yuma his Heart Piece . Tori comes closer , and while the three talk , Astral flies all around the construction site , intrigued by it . Tori makes a remark , and both Yuma and Cody seem embarrassed . A man suddenly screams at them , angry for the destruction they caused before and what they ' re doing there , the three run away yelling " Sorry ! " ( in the dub , the reason why the worker wants Cody and the others to leave is because his he doesn ' t want to see Cody ' s dad see him at the site ) . Featured Duel : Yuma Tsukumo vs .
