" in the Japanese version , is the sixty - eighth episode of the " Yu - Gi - Oh ! ZEXAL " anime . It first aired in Japan on August 20 , 2012 , and in the United States on July 6 , 2013 . Summary . Still trapped in the Sphere Field , Yuma and Astral , using ZEXAL , are talked to by Dr . Faker , who laughs maniacally after he ' s done . As Yuma questions Faker ' s statements . However , they see they have been transported to another location ; Heartland Tower . Following Dr . Faker ' s explanation of the location , the attack he saw after regaining a memory from suddenly makes sense to Astral . Faker then has all of the " Number s " he took from them and Vetrix appear between them ( in card form ) . At that moment , Kite and Orbital 7 enter Hart ' s room , only to realize he ' s not there . Faker explains to Yuma the purpose of the WDC ; gathering a lot of " Number " cards for the Sphere Field Cannon as a power source . Kite ' s losing to Vetrix was not as planned , but since Vetrix took Kite ' s " Numbers " the effects was the same . Angered by all problems Faker has caused , Yuma tries to punch him , but Faker reveals his appearance in the Sphere Field is just a hologram . He then orders Hart , who ' s looking unresponsive and in trance , to do his job . Kite has Orbital bring up a map of the tower , who tells him Hart is down around the Sphere Field , shocking Kite . On Faker ' s order , Hart floats into a gap in the wall , fitting his body , which then proceeds to put parts of the wall on him , activating his powers and seemingly causing him pain . Shocks are then released on him from the cables on the wall . Outside of the stadium , the spectators of the WDC Finals are being led to safety . Bronk , Flip , Cathy , and Caswell get outside , but notice Tori isn ' t with them . Yuma ' s sister , Kari then comes through the public riding her motorcycle . Elsewhere , Tori sees the explosions on Heartland Tower , worried for Yuma ' s safety . Kite notices light coming from his Deck , seeing the " Neo Galaxy - Eyes Photon Dragon " card glow , a reaction to Hart using his powers . The building begins shaking all of a sudden , and the top of the tower breaks down , making the ceiling collapse on Kite . On the walls of the Heartland area , Kari is with Yuma ' s friends , trying to call Tori via the D - Gazer . She eventually picks up , telling her location , and then cuts the call immediately when she sees Kite trapped under a part of the collapsed ceiling . Shark comes running down a set of stairs , looking for Yuma . He comes across Tori and Orbital 7 trying to lift the boulder on Kite . Albeit surprised by his sudden appearance , Tori leaves the lifting of the boulder to him and they get Kite away from underneath the rubble . Tori thanks Shark , who calmly says it ' s no problem . Kite tells them Hart is in trouble , to which Tori shakes Orbital 7 asking him where he is . He says it ' s the Sphere Field Cannon , and tries to explain it ' s purpose , before Shark cuts him off asking him where it is . Kite then tries to walk away ignoring Shark ' s question . The two get into a small argument , with Kite bringing up Shark ' s 4000 to 0 defeat at his hands some time before ( this flashback is cut from the dub ) , with Shark saying that it won ' t happen again next time . Tori interrupts them , since it ' s not the time for an argument like that . Shark then explains his reason for coming ; saving Yuma , which surprises Tori , and he angrily shouts at Orbital again to tell him where Yuma is , ticking Orbital off , who refuses to tell him . Tori then begs Kite to bring them with him , and Kite remembers the times Yuma was worried about Hart . He tells Orbital to come with him , and , keeping his cool , lets Tori and Shark come along . Still trapped , Yuma is getting exhausted by being in the Sphere Field . Astral apologizes to him , saying it ' s all his fault since he wasn ' t strong enough . Yuma denies it , and says Hart needs saving more than he does right now . Kite , Tori , and Shark are in front of a door blocked by rubble , and Shark and Orbital get into a small argument again . Tori calls Kari to get a way through the building they can get through , which she gets . The three arrive in the room with the Sphere Field , but are blocked by Mr . Heartland , who ' s still on his floating platform , and they see Yuma suffering inside the Field . To prevent their advance , Heartland sends out several groups of Litterbot s to dispatch them , and the Bots turn into combat forms and on Kite ' s command , Orbital does the same . Smashing several of the robots , and taking one each of their scythe - like weapons and arms respectively , Kite and Shark break more of them . When Tori breaks one too , Orbital comments on it , but Tori tells him off saying he should keep doing his best too . Mr . Heartland then starts preaching to the three , provoking Kite , and opens a part in the center of the room , and has more robots come to attack the kids . He then says it ' s a gate to the Astral World , which the cannon will fire into . Kite looks at the suffering Hart , and Dr . Faker smiles happily in his room since 92 % of the needed energy was already collected . The robots begin to overwhelm Shark , who once again ticks Orbital 7 off by telling him he should do more . Albeit angry , Orbital scans the room for a way to shut down the bots . Orbital finds a spot , and Kite orders him to hack into it . Using his " Orbital Step " the little robot does so , and manages to both malfunction the machinery in Dr . Faker ' s room as well as shut down the hostile robots , but the shocks he received from it seem to take their toll on him . As a result , the power drops and Mr . Heartland is sent down the well to the portal along with his platform . Tori holds Orbital in her arms , and despite not knowing it well , cries when it shuts down . Yuma instantly feels relieved when the power of the Sphere Field lowers , and is surprised to see his three rescuers . Astral then undoes ZEXAL , and frees " " and " " for Yuma to take with him , and mentions ' hope ' and ' future ' . He then tells Yuma to go and save Hart and the Astral World , sending Yuma out of the Sphere Field bubble . Tori and Shark are relieved to see Yuma , but before anyone can say anything , Faker appears from a door opening in the wall , sitting on a huge platform . Yuma sees the " Numbers " , " Utopia " and " Shark Drake " in his hand and remembers Astral ' s words , telling Shark and Kite he needs their power , citing Astral ' s words . Kite picks up his " Neo Galaxy - Eyes Photon Dragon " from his Deck , deciding to join Yuma . Shark accepts " Shark Drake " from Yuma , and the three strike a pose putting the three Xyz Monsters " Utopia " , " Neo Galaxy - Eyes Photon Dragon " , and " Shark Drake " together in the air , and Yuma challenges Dr . Faker , who gladly accepts their offer to take the two " Numbers " back from them . Tori then wishes for Yuma to be safe , preparing herself to watch the upcoming Duel .
