Yu - Gi - Oh ! ZEXAL - Episode 019 " The Edge of the World " , known as " The Promised Kattobingu " in the Japanese version , is the nineteenth episode of the " Yu - Gi - Oh ! ZEXAL " anime . It first aired in Japan on August 15 , 2011 and in the United States on April 14 , 2012 . Summary . The episode opens with Tori waking Yuma up , and informing him that school is over . She then tells him that the teacher has made an announcement about School Spirit Day on the upcoming Saturday , where the student ' s parents visit their children to check on their grade condition . However , since Yuma ' s parents aren ' t around , they will not be visiting . Bronk then shows up and asks Tori which one of her parents will show up but apologizes to Yuma when he realises he ' s there . Yuma insists that he doesn ' t mind , and , on the way home , Astral asks Yuma what a school spirit day is and he explains that parents go to their school to see how their grades are going . Astral is then about to comment about the absence of Yuma ' s parents but he says he will ask his grandmother or sister to come . However , when he gets home , and goes to ask his grandmother , it turns out that she is planning on going to a reunion on that day . Yuma goes on to ask Kari , but before he can ask her , she gets a call from her friend Brianna , informing her about a reunion on Saturday . Not wanting to interfere with their own plans and disappoint them , Yuma doesn ' t mention the school spirit day to either of them . Later , when he goes to sleep , he looks at the picture of his parents sadly . On Saturday morning , as he is hurrying to school , he literally runs into his sister , who is dressed for a formal occasion , and his grandmother . When Yuma is about to leave , Kari finds it strange that Yuma has classes on a Saturday and asks him if he ' s attending detention . Yuma denies it , but avoids saying why he ' s going to school . While waiting at a crosswalk , Yuma notices he lost his pendant , and he ( and to a lesser extent Astral ) panics about it . While they are looking for it , Astral reminds Yuma about the importance of the item , to which Yuma responds by saying that he knows about it , and that it was a gift from his father , Kazuma Tsukumo . This causes Astral to ponder a possible connection between himself and Yuma ' s father . Curious , he asks Yuma about his father . Yuma responds to Astral that his father was a daring , and adventurous person , and that he who give the key to him . It then flashes back to a younger Yuma rock climbing with his father . Kazuma encourages him to keep climbing , to which Yuma says that he can ' t . Kazuma offers Yuma a hand , and tells him to do " kattobingu " . It then shows Kari with her grandmother and mother back in Heartland , with Kari complaining that Kazuma and Yuma went climbing . Haru says that it is because they had to have a " man talk " . Kari laments about how she wishes she was a boy , but her mother , Mira Tsukumo , appeals to her by offering a chance for the three of them to go on a " girls night out " , which cheers Kari up . Back with Kazuma and Yuma , Kazuma notices Yuma sulking , and asks him if something happened at school . Yuma remembers how he failed to win in a Duel against some of his classmates , and he was teased about it . However , he doesn ' t tell his father about it , and says that he doesn ' t want to go to school . In an attempt to cheer Yuma up , Kazuma asks him about the " other universe " . When Yuma questions his father about it , Kazuma tells him that next to their world , is another universe , and that there universe is filled with hope , while the other needs it . He then tells Yuma to always make a drive for something , and to strive for hope . When Yuma asks about the other universe , Kazuma hugs him , and tells him to fill his heart with something he wants . He then puts Yuma on his shoulders , and asks him what his aim is . Yuma answers by telling him his aim is to become the Duel Champion . His father tells him never to give up on that drive , and to always continue for it . Father and son then Duel , with Yuma apparently on the losing end . Kazuma attempts to Xyz Summon , but fails , as he doesn ' t have any Xyz Monsters in his deck , much to Yuma ' s dismay . Later in the night , Yuma asks Kazuma what his dream is , to which his father answers by saying his dream is to go to the edge of the world . Yuma laughs , and tells him that the Earth is round , so there is no edge . His father laughs at this , and the two laugh together at the notion . At some point in the future , Kazuma and Mira were somewhere in a tundra . The two notice a flash of light , before the ice cracks beneath them . Kazuma falls down , but Mira manages to save him with the rope connecting them . Figuring that it would be a better chance for her to survive if he cuts the rope , he prepares to do so . Mira begs him not to do it , but he says he ' s not giving up hope . He says there ' s still the hope that Mira survives . He cuts the rope and falls seemingly to his death . He later wakes up , still alive , in what appears to be the Astral World . A strange entity , baring some resemblance to Astral himself , appears before him , and drops the Emperor ' s key into his Kazuma ' s hand . Kazuma then sees the world being bombarded with strange energy , causing it to be damaged . One week later , he is saved and apparently transported via helicopter , badly injured , but still alive , where his family surrounds him . Yuma notices the key in his hands . It later shows Yuma Dueling the same trio of upper class boy , and losing . While he ' s being mocked , his father shows up , and tosses him in the key , shouting him encouragement telling him to do " kattobingu " ( feel the flow in the dub ) . Back in the present , Yuma then mentions to Astral that Kazuma said he would teach Yuma forever about Dueling . Back at the present day , at school , Flip and Caswell are both admiring Tori ' s mother , marveling at her beauty . One comment they make causes Tori to glare at them , and they shift their gaze to Tetsuo ' s mother Tetsumi , who bares a resemblance to her son . The two then lament over the similarities in DNA . Mrs . Meadows mentions to Tori how Yuma wasn ' t there , to which Tori seems worried about . Eventually , Yuma and Astral return to Yuma ' s house , and manage to locate the key , much to both of their relief . At a local restaurant , Haru and her friend Meredith ( Tori ' s grandmother ) are talking with each other , whilst a Duel apparently goes on in the background . The two talk about similarities with their relationship and Yuma and Tori ' s , and how Tori has been going to Yuma ' s house lately , but they soon forget what they were talking about , due to all the noise . At another location , Kari is meeting her friend Brianna , and mentions about how her journalist report is stressful . Brianna asks if Kari went to school spirit day , causing Kari to remember Yuma planning on asking her something . Realising what he was going to ask her , she hurries out . While driving , Kari thinks about Yuma ' s courtesy , and how he didn ' t want to interfere with their own feelings . She then remembers how her father warned her about being careful with Yuma ' s duels , for some day , a great destiny would awaken from one of his duels . Kari complains about how it ' s always about Yuma , but Mira tells her that as his big sister , it is her duty , and that Yuma will rely on Kari for a long time . Yuma eventually makes it to class ( albeit very late ) , and runs into all the parents and students . Later in PE , Tori and Caswell are going to jump over some boxes , with the support of Caswell ' s mother and Bronk ' s mother , respectively . Tori manages to clear the boxes , but Caswell only makes it halfway , and ends up landing on his face . Bronk mentions to Tori how no one in Yuma ' s family showed up , making Tori concerned . Meanwhile , Astral is hovering overhead , watching Yuma , who is leaning on the wall in the background , carefully . Kari and Haru eventually push their way into the scene , and demand as to why he left them out on this . While Yuma is wondering about it , they both offer their support , encouraging Yuma to go forth . Tori and Bronk both urge Yuma to do a " kattobingu " , as usual . Yuma then opts to go over 20 boxes , imagining it as a large mountain . Yuma smiles , and when Astral asks him what ' s on his mind , Yuma answers by saying that his parents are watching over him . Astral smiles , and mentions how he thinks he can also see them . While Yuma ' s friends and family shout their support ( Tori even believes that this time he ' ll make that jump ) , Astral makes his 14th Observation , this time , one about how everyone loves Yuma . He then tells Yuma to go for it , and Yuma jumps up . Featured cards . The following cards appeared in this episode . Cards in italics debuted here .
