At Heartland Academy , a group of three girls discuss the finals of the World Duel Carnival , saying that two of the finalists are from their school . As Yuma runs towards them , one says that one of the finalists must be Reginald , but she wonders who the other one is . The third asks what it is that person always says . Yuma leaps into the air , yelling " kattobingu " and falls next to them . He gets up and runs around , asking if anyone wants his autograph . Tori , Jen and Summer are standing nearby . Summer and Jen say that he ' s so full of himself for some reason . Bronk is also close and calls Yuma an idiot . Tori grabs Yuma by the ear and drags him away . Flip sees the whole thing and looks around quietly . Later , Yuma sits with this friends and Tori tells him to calm down . He says he did the make the finals though - its alright that he ' s confident . Yuma shows them the invitation he received to the party for the finalists on the eve of the finals . He says it ' s in Heartland . Everyone is excited , with Caswell saying that many famous Duelist s will gather and Cathy wonders what she should wear . Yuma says it was him that invited , not them . Flip looks in from around the corner , smirking and saying he has a good idea . At a hotel , Vetrix walks through a set of double doors , where Quattro and Quinton are waiting . Vetrix glances at Trey , still unconscious after Dueling Yuma . Vetrix begins to walk away and Quattro asks him to wait . He asks Vetrix to give him new powers just like he did for Trey . Vetrix replies that he ' s disappointed in both of them . Enraged , Quattro runs forward , saying that Trey fought against the original " Number " for Vetrix and ended up like he did . Vetrix says what he wants is results . If he can ' t rely on them , he ' ll find someone else - like Shark . That ' s why Vetrix wanted him to participate in the tournament to begin with , he says . Vetrix walks off and Quattro screams for him to explain himself . Elsewhere , Kite is hooked up to a machine while Orbital 7 types away on a nearby terminal . Lights flash , and when they clear , Kite dresses and begins to get his feet . Orbital informs him that ' s he ' s reached his limit - Orbital implies that if he continues to use Photon Transformation to hunt the " Number s " , he will die . From a nearby screen , Mr . Heartland comes into view and says that Kite is surely pushing himself . If he asks if Kite is alright . Orbital begins to tell Heartland about the condition of Kite ' s body , but Kite cuts him off , saying there is nothing wrong . Heartland says that ' s good and tells Kite he ' s counting on him , since the " Numbers " have all gathered in Heartland - the time to act is now . Kite says he ' s aware of that and reminds Heartland of his promise to heal Hart . Heartland says " of course " and tells him not to worry about that . He tells Kite he ' ll await him at the party tonight - it wouldn ' t hurt to scope out those that hold the " Numbers " . Heartland cuts the connection and Kite and Orbital proceed to leave . Nearby , Dextra is seen , having heard the conversation . That night , fireworks are lit off as people gather near Heartland Tower . Yuma and his friends arrive , with Bronk saying that no matter how many times he comes to Heartland , he ' s always impressed . Tori says it ' s so beautiful . Cathy pops up behind her , saying that Tori tried hard to dress up . She says that people need nice clothes to look good , just as birds need feathers ( Tori ' s Japanese name of Kotori means " little bird " ) . Insulted , Tori says that Cathy looks good in her " cat demon cosplay " as well . As they continue to argue , Yuma asks them stop as the Emperor ' s Key glows and Astral appears . He explains that Heartland was founded by Dr . Faker as a paradise where both adults and children could enjoy themselves and that he allows poor children to live to there to experience happiness . The rest of the world praises it as a paradise . Yuma asks how Astral knows so much about it . Astral explains that the " Numbers " they obtained from Trey were memory pieces with information about this world . Yuma is annoyed , knowing Astral will try to teach him all about it . The group arrives at the main entrance , with Caswell commenting on the red carpet . Tori says she feels like a celebrity and Cathy meows . Two event bouncers in tophats approaches them , saying an invitation is required . Yuma explains that he has one and digs through his pockets for it . He ' s forgotten it . The bouncers throw him out , with him insisting he ' s a finalist . One of the bouncers says there ' s no way a kid like him could be a finalist . Yuma says he ' s not lying and they tell him to just show the invitation , then . The bouncers leave and Flip appears , saying there ' s always a ura side to things . He says he has an idea . They enter under the red carpet , crawling . As they do so , a fan yells that she can see the female Duelist , Milky Kulala . Tori bemoans the fact that her dress is getting ruined . They pass directly under a couple that ' s walking in , who are thrown into the air . The carpet flies up and the whole crowd sees them . The bouncers run in and the group runs towards the entrance , with Tori calling all of them idiots . As they reach the top of the stairs , Flip hides behind a pillar . Flip giggles and muses that Yuma and his friends are only good as tools . A crowd is gathered nearby around a tall man in green robes and a white mask . He realizes it ' s a finalist and smiles . Yuma ' s group reaches the next set of doors , which are also guarded , so they ' re cornered . Yuma again insists he ' s a finalist . Nistro arrives , saying he wondered who was causing the commotion . As always , Yuma has made a mess . He asks what the problem is . The bouncer says he came in with no invitation . Nistro says it ' s fine , despite his looks , Yuma is indeed a finalist . The bouncer starts to argue and Nistro asks if he doesn ' t believe him . The two back off and leave . Nistro asks if Yuma thinks he ' s tough , but he ' s already continued on inside . Many people have gathered and by the staircase at the back of the room is a giant cake , topped with a heart . A band of litterbot s provide entertainment . Yuma is amazed by the cake , while Caswell excitedly takes out a pair of binoculars that provide information on Duelists when looked through . He sees some of the finalists , such as Pepe Perez from Latin America ( in the dub , Pepe is from Brazil , which is technically a part of Latin America ) and the noble knight , Lord Percius . Then there ' s the Triad of Terror , who have won many tournaments and are known for striking fear in their opponents . Yuma grabs the binoculars , looking for Shark and Kite . He finds Kite and Quinton nearby . The device ' s scan of Quinton reveals nothing about him , save his age of twenty , whereas the other scans revealed origins and Deck types as well . He remembers meeting Quinton , who told him that his father was still alive in the Astral World . Kite grabs Quinton by the collar . Quinton tells him that ' s very unlike him and lightly lowers Kite ' s hands . Kite tells him not to play games and asks why they did what they did to Hart . He calls Quinton a former mentor of his and Quinton asks if he can ' t forgive him . Kite again asks why - what are they aiming to do . Quinton says they just follow the will of Vetrix . Kite doesn ' t seem to know who that is and Quinton says that he ' ll meet him soon . Kite asks if he means in the finals . Quinton places his hands on Kite ' s shoulders and says that in his current condition , Kite will not be able to win against him or Vetrix . Quinton departs with a worried expression . Yuma is running around , still looking for Shark , as he had something to ask him . He sees Quattro nearby , signing autographs for a number of female fans and saying that fanservice is his motto . Quattro happens to glance out the window and it ' s there he sees Shark standing alone outside . His expression hardens and he runs off , pushing his fans out of the way in the process . Quattro catches up to Shark , but says nothing . Shark turns and asks him what ' s wrong - it was always Quattro that had the talk . Quattro growls and Shark says the time has come and that he will bet everything he has to defeat Quattro . Shark walks away , leaving Quattro behind . On a balcony , Kite is approached by Dextra . She says she thought something was wrong with his current condition . Kite asks what she ' s talking about and Dextra responds that she heard from the infirmary - his body is failing . Kite responds that eavesdropping isn ' t a good hobby . Dextra says she knows that Hart ' s condition is bad and that Kite needs the " Numbers " to help him . Despite that , he ' s not fit to go the finals . Kite says he has no obligation to follow her orders . He says that Quinton and Vetrix ; the ones who kidnapped Hart , will be in the finals . Dextra looks very upset and Kite says he won ' t ever lose . Elsewhere , Mr . Heartland meets with Dr . Faker . The latter complements him on the fact that the evening is going well . Heartland says the plan is proceeding well and Faker asks if everyone has gathered . Heartland says that one has yet to show up - Vetrix . Heartland asks if Faker is familiar with him , which Faker denies . Heartland says he must go to greet in the finalists . Yuma and his friends sit on the stairs , with Caswell still looking around with his binoculars . He says that he supposes Flip wasn ' t able to enter . The tall man in green walks by , with Caswell saying that he must be the most powerful amateur Duelist int he world - the vampire of midnight , Count Crazy Fang . Caswell asks for an autograph , which Count Crazy Fang gives - but it ' s just some scribbles . Count Crazy Fang departs , muttering " ura " ( in the dub , he didn ' t say anything ) . The litterbot band performs a drumroll as the lights dim and Mr . Heartland enters from the topmost door , projecting a larger hologram of himself and yelling " Heart Burning ! " Heartland asks if everyone is enjoying the party and says that the final matches of the WDC will take place tomorrow . He ' ll now introduces the twenty - three remaining Duelists who has gathered ( there were supposed to be 24 finalists , but Trey had fallen comatose ) . He begins by saying " first " , when the hologram suddenly flickers and dies . Childish laughter is heard and two spotlights activate , illuminating Vetrix , who stands at the bottom entrance . Vetrix walks forward , people in the crowd backing away when they see him . He spots the giant cake , excited . He reaches the stairs just below Heartland and turns to face him . Heartland asks who is and Vetrix introduces himself . Vetrix climbs the last staircase and kneels on the last step and Heartland smiles , kneeling in front of him and asking him what ' s wrong . Vetrix informs him that he will destroy him and the others . Vetrix runs to the balcony and leans over , saying he really loves cake . He turns to Yuma , calling him " big brother " and asking to meet in the finals . He then turns and stares directly as Astral , able to perceive him . Astral asks if he can see him and Vetrix responds with more laughter . The spotlights dim and the lights return , with Vetrix having vanished . A man in a tank top and boxer shorts runs into the room , leading the two bouncers from earlier . The man points to Count Crazy Fang , calling him an imposter . Count Crazy Fang is Flip , who attempts to escape . He knocks over Caswell in the process , dropping a fake arm - a glove attached to a stick . Unable to see through the mask properly , he collides with the cake . The real Count Crazy Fang jumps at him , but Flips moves and Count Crazy Fang knocks over the cake , splattering icing all over Mr . Heartland . Yuma and his friends chase after Flip , in turn being chased by the bouncers again . Flip trips over a cart of pizza on one of his stilts . The pizzas hit various people in the face , including one of the bouncers . Amidst the chaos , Mr . Heartland takes off his tophat and mutters " Vetrix " . Yuma and his friends run through the forest outside and Yuma stops when he notices Kite standing nearby . Everyone but Tori continues to run . Yuma ask Kite how Hart is doing . Kite says he shouldn ' t worry about that - he should worry about settling things with him . They both say they intend to go all - out . Kite tells him not to misunderstand . It ' s not Yuma he desires to defeat with all his strength - it ' s Astral . Kite turns to leave , sparing a glance at Astral in the process as Yuma smiles . In a limousine , Vetrix sits playing a handheld game while Quinton conducts a meeting with the three Triad of Terror members . Wolfsbane asks if he wants to hire them , with Quinton confirming that . Wolf responds that they are very expensive . Quinton opens a briefcase , saying he has the initial payment here and will pay the rest once the job is finished . Wolf asks who the target is and Quinton tells him it ' s a man named Yuma Tsukumo . Vetrix completes a level on his game , giggling as fireworks go off .
