Yu - Gi - Oh ! ARC - V - Episode 015 " In it to Win it " , known as " The Aim is the Junior Youth Championsip ! ! " in the Japanese version , is the fifteenth episode of the " Yu - Gi - Oh ! ARC - V " anime . It first aired in Japan on July 20 , 2014 and in Australia on November 1 , 2015 . It became available with official subtitles via Crunchyroll on November 15 , 2016 . Summary . Zuzu recounts the events that happened in the last episode . The confrontation against LID ended , while Skip succeeded in snapping Yuya out of his depression . Zuzu swears to get stronger after losing to Julia . At Paradise Prep School , Yuya is having lunch . He removes the lid of his lunchbox and stares at the picture of his father on the bottom of the lid . Yuya promises to hone his skills to be a pro Duelist and make everyone smile someday . After making the promise , Yuya digs into his lunch with gusto , psyched about his goal . Next to Yuya , Zuzu reminds him not to talk with his mouth full ( in the dub , Zuzu says just because Yuya is eating seafood doesn ' t mean she wants to see it ) . Suddenly , a hand offers Zuzu a handkerchief . Surprised , she looks up to find Sylvio , who greets her . Zuzu looks away in disgust and Sylvio remarks that Yuya is uncouth in front of a lady because of his Dueling and eating habits ( in the dub , Sylvio compares Yuya ' s eating habits to his Dueling : not elegant ) . Yuya acknowledges that his eating habits are dirty , but is insulted to hear that his Dueling is the same way ( in the dub , Yuya asks Sylvio if he wants something , or if he ' s here to annoy him or Zuzu ) . Sylvio replies otherwise ; he heard that Yuya ambushed someone else , which Zuzu denies , not before wondering about who got attacked . Sylvio says an LID Xyz Summon lecturer was attacked . Yuya and Zuzu remember Henrietta calling out to Declan to leave You Show to address the issue . Sylvio admits that he was kidding about Yuya being the attacker ( in the dub , Sylvio remarks that Yuya is genuinely surprised hearing about this and admits he had the feeling that the rumors were wrong ) and reiterates that an LID teacher was the victim , whom Yuya couldn ' t beat with his " cowardly " Pendulum Summon s . Once again , Yuya takes offense to the comment , asking why it ' s that way . Sylvio leans in close and says it ' s unfair that only Yuya has it . He adds that he heard rumors that Leo Corporation is independently producing Pendulum cards and expresses his desire to get his own to defeat Yuya . He ends the conversation there and leaves Yuya and Zuzu , promising to meet them at the Arc League Championship ( in the dub , Sylvio adds that he and Yuya can ' t Duel just yet , since Yuya isn ' t qualified ) . For a brief moment , Yuya is confused about Sylvio ' s words , not before frantically realizing that he can ' t become a pro in his current state . After school , Ally , Tate , and Frederick greet Yuya and Zuzu at the school gate . Tate tells them to hurry on to You Show , but are surprised to see Yuya in a glum state . Tate asks why Yuya is that way . On the way to You Show , Ally and Frederick learn that Yuya isn ' t qualified for the Arc League Championship . Yuya confirms it and states the conditions for entering : 50 Duels with a 60 % win rate . Ally asks what Yuya ' s current record is . He responds with , " 46 Duels with 26 wins " . Tate does the math in his head : Yuya ' s current win rate is 56 . 5 % , which still isn ' t enough to enter . Frederick is impressed that Tate did his math so quickly ( in the dub , Frederick calls Tate a human calculator ) . Tate notes that Yuya still has four more Duels , which he must win , before he fulfills the requirements . Zuzu says she and Yuya asked around school for four more Duelists , but they had no luck because all the students refused to Duel Yuya for beating a pro , the Sledgehammer , which should get him a free pass to the Arc League Championship . Yuya yells that the students got the wrong idea : the Duel he had with the Sledgehammer was only an exhibition match . Tate says in order to become a pro , they had to win the Arc League Championship . Frederick continues with said winner having to pass the Youth Exam and win the Youth Championship . Ally finishes with the last requirement : passing the Pro test . Yuya bemoans he couldn ' t take the first step forward and resolves to Duel four people ( in the dub , Yuya exclaims that everyone thinks he ' s a pro because he already beat one , but he can ' t become one unless he qualifies , and he can ' t qualify because no one will Duel him and no one will Duel him because they think he ' s a pro ) before realizing he can just Duel his friends . The three children refuse because they are still elementary school students and part of the Junior class . The Junior Youth subdivision is for middle schoolers . Yuya decides to challenge Zuzu as part of his four people , but she refuses as well because she already qualified and she has had plenty of practice Duels with Yuya , so it would be pointless for her to Duel him ( in the dub , Zuzu refuses because she does not want to lose her 60 % record by losing to Yuya ) . Yuya angrily asks for a suggestion ; Zuzu suggests that he Duel Gong because Yuya got most of his wins from Dueling in the Strong Dojo . Yuya admits that he was grateful to Gong for helping him whenever he needed it and for making him aim to become a pro ( in the dub , Yuya is grateful to Gong for helping defend You Show ; it was his training that helped Yuya defeat Dipper and Gong himself tied with Kit to keep You Show safe from LID ) . This is also the reason why he doesn ' t want to rely on Gong anymore ; Yuya wants to become someone who Gong can rely on with his own strength ( in the dub , Yuya promises to get stronger starting now ) . Zuzu repeats Yuya ' s words and admits he was right . She runs off , with Yuya asking why . She tells him not to worry about it ; she wants to get strong too ( in the dub , Zuzu makes up the excuses of running errands , paying bills , and places to be ) . Tate reminds Zuzu that they still need to get to You Show , but she tells him to inform her father that she won ' t come today . Yuya wonders what just happened . Ally replies that this is because he praised Gong alone . Tate says this was true ; he didn ' t have any thanks for Zuzu . Frederick smugly asks if Yuya just doesn ' t get it . Yuya denies the children ' s claims ; he ' s grateful for Zuzu , like he is for Gong . Ally says Yuya was too late , to Yuya ' s chagrin . As Zuzu continues running down the street , she muses that Yuya is trying to change and realizes she can ' t just stay the way she is now . She promises to get stronger so she can protect You Show . At You Show , Yuya remembers his promise not to rely on Gong to get stronger and wonders how to look for the other four Duelists ( in the dub , Yuya ' s thoughts are replaced by Ally suggesting Yuya to find a matchup center for Yuya to look for his four opponents , with Tate saying the problem is looking for Duelists willing to Duel Yuya ) . As Yuya enters the lounge , he is greeted by , " Oh , my boy ! " Nico Smiley rushes to Yuya and shakes his hand . He says it ' s been a while since he last saw Yuya . The children recognize who Nico is and Yuya asks why he ' s here . Skip says Nico bought Yuya a ticket to get into the Arc League Championship , no strings attached . Yuya asks if this is right and Nico confirms the truth : the Paradise City Duel Association let Yuya enter the Arc League Championship , even if the Duel he had with the Sledgehammer was an exhibition match , because he won that Duel . Tate congratulates Yuya for getting in , while Frederick gets his shivers . Yuya becomes saddened , which Skip is quick to notice . Yuya admits that while he ' s grateful for the invitation , he refuses after remembering a student telling him that him defeating the Sledgehammer was a free pass to the Championship . The children and Nico are surprised . Nico asks Yuya why and he replies that it ' s unfair to do that . Nico says this isn ' t unfair at all ; Yuya should be proud that the Duel Association gave their approval ( in the dub , Nico calls the invitation favoritism on his part , but rephrases it by repeating his point of Yuya being in the Championship ) . Yuya says he felt bad for the Sledgehammer and asks how he ' s doing . Nico says the Sledgehammer isn ' t the champion anymore . He gave up his title after his loss to Yuya and went overseas to train . Because of this , Nico was left without a Duelist to manage . He offers Yuya the chance to aim for the top together . Yuya refuses the offer and Nico falls flat on his face . Tate says he understands : Nico was betting on the council ' s approval , while Fredrick continues he did it to make money for himself . Ally calls him the worst . Nico grabs Yuya ' s hand and says he ' s interested in his talent . Yuya asks Nico for a request if he was so dedicated to that talent . Sora stands in front of the LID building and muses that he never thought that Declan was the president of Leo Corporation and the son of the director . He notices the many guards surrounding the building ; they aren ' t the kind of people who ' d let Sora in to see Declan if he asked . As he thinks , a professor places his hand on a handprint detector provided by a guard . The guard motions the professor to proceed . Sora is frustrated that he wanted to Duel Declan and licks his lollipop . Suddenly , Zuzu calls out to him . She explains that she knew that Sora wasn ' t coming to You Show because he wanted to Duel Declan . Sora tries to deny it , but Zuzu recalls that Sora approaches people he ' s interested in , such as Yuya ( in the dub , Zuzu calls Sora a slimy weasel because he wants to latch on to people he wants to Duel better ) . Sora admits this was the truth because of his mastery of Fusion , Synchro , Xyz , and Pendulum Summoning . Zuzu reminds Sora that Declan isn ' t a person who can get close that easily . Sora replies this is because Declan is the Leo Corporation ' s president ( in the dub , Zuzu reminds Sora that he wanted to learn at You Show , but Sora says he left because he thought You Show didn ' t like him ; Zuzu says he got it all wrong ) . Zuzu takes Sora by the hand and leads him away from LID . Sora asks where they ' re going , but Zuzu simply tells him to come . Meanwhile , the masked Duelist watches from a nearby building . Julia , Dipper , and Kit stand in front of a crime scene . Julia tells her friends that she heard the attack happened here . Kit says this is it for the suspicious part ( in the dub , Kit remarks the caution tape was the giveaway here ) . Dipper comments that there ' s something LID isn ' t telling them . Inside , LID professors are analyzing the damage . Julia goes underneath the caution tape to try to enter , with Dipper trying to stop her . A professor opens the door and asks Julia why she ' s here . Julia replies she isn ' t anyone suspicious and introduces herself . The brown - haired professor , Herk , notices what ' s going on . Outside , Kit and Dipper introduce themselves as well . Herk comes outside and asks the trio if they ' re students of LID , which they confirm . Herk also asks if the three students had heard of what had happened . Julia replies that they heard that Marco got attacked and the LID Secretariat refused to let them see him ( in the dub , Julia adds that classes would be canceled as well ) . Kit asks if Marco was attacked in the middle of a Duel . Dipper says he heard that the culprit was an Xyz user ; as an Xyz user himself , he does not like people abusing it ( in the dub , Kit says he heard the attacks happened because Marco was an international spy , while Dipper says he heard Marco was attacked by an alien ) . Herk apologizes to the students ; they can ' t discuss the details , as LID is still investigating the crime ( in the dub , Herk notes the students ' concern ) . Julia inquires if Marco is okay , but the professor refuses to give the details about that as well . However , he reassures Julia that LID is doing everything they can to figure out what happened and encourages her and her friends to improve their Dueling skills , as this is what Marco would have wanted . If Julia understands , then she and the others would go back to LID and leave the investigation to the professors ( in the dub , Herk warns Julia to forget that she and her friends were at the warehouse or even talked to Herk ) . Dipper and Kit agree without hesitation , while Julia is reluctant . Herk returns to the crime scene . Kit remarks that the Uniformed Unit is cool , while Dipper says this is because they passed the pro test to be on top and expresses his desire to be with them . Julia does not share the boys ' sentiment and leaves . Dipper asks where she ' s going and Julia tells them to go home ( in the dub , Julia yells that she has another lead ) ; she has other places to be . The two boys are confused . Zuzu has taken Sora to a warehouse at the pier . Sora asks why she brought him here . Zuzu approaches him and begs him to teach her Fusion Summoning . Sora asks why , and she says she wants to become stronger . Sora wonders if this is because Zuzu lost to Julia at You Show . She recalls the moment when she thought she had an Action Card , but it turned out to be a reflection , with Julia chiding her for being deceived . She also remembers that Declan gave You Show the win and repeats her desire to protect You Show . Sora asks if Zuzu ' s request is true and Zuzu begs him again to teach her ( in the dub , Sora doubts Zuzu ' s sincerity , since she called him a slimy weasel earlier and Zuzu apologizes for that ) . He starts to think about it , which Zuzu takes as a sign that he ' s refusing . Sora replies that it ' s not that he can ' t , but rather if it ' s okay ; he admits that it ' s true that Zuzu would get stronger . Zuzu is eager to get stronger so she won ' t lose to anyone . Sora starts to have second thoughts as the masked Duelist eavesdrops on the pair . Nevertheless , he agrees to teach her and shows her " Polymerization " , the card required to fuse monsters together for a Fusion Summon and the bread and butter for Fusion Summoning in general . Zuzu says she understands . Sora thinks he can ' t believe he ' s teaching her ; being too nice is his only flaw . After looking at the card , Zuzu asks if the Fusion Material s can be on the field or hand . Sora regains his focus and confirms the mechanic . He clarifies that all the required Fusion Materials have to be in either place for the Fusion Summon to work , though there are exceptions . Zuzu recalls that the Fusion Materials are sent to the Graveyard during the Fusion Summon , while the Fusion Monster is Summoned from the Extra Deck . Sora praises Zuzu for getting it right before noticing they ' re being watched . The masked Duelist leaps from his hiding spot , with Sora in pursuit . Zuzu asks what ' s wrong , but Sora ignores her and arms his Duel Disk . Zuzu is confused about the turn of events as Sora chases the Duelist , who activates his own Duel Disk . Sora also activates his Duel Disk and the two clash with the holographic blades as if they were swords . Both Duelists leap back , with Sora asking who the masked Duelist is . The masked Duelist does not answer , but Sora notes that the Duelist isn ' t from around here . The Duelist also makes the same statement . Zuzu recognizes the masked Duelist as the one who Dueled and defeated Sylvio . Sora is surprised that Zuzu knew him already and Zuzu replies that he came when she was with Sylvio . Zuzu asks if the Duelist was responsible for the recent incident , but he does not respond . Sora wonders what Zuzu is talking about and Zuzu explains that an LID professor was attacked . Sora realizes that this was why so many guards were posted around LID and repeats Zuzu ' s question . The Duelist still does not answer . Zuzu inquires who the Duelist is and if he Dueled Sylvio in order to save her or if he held a grudge against LID . Suddenly , the warehouse doors fly open and Julia yells that this is the culprit , then . Julia approaches the Duelist and demands if he was responsible for Marco ' s disappearance . Zuzu wonders what Julia is doing here . The LID student replies that she thought she could get something from the scene of the crime ( in the dub , Julia demands who the Duelist is and what he did with Marco ) . She arms her Duel Disk and says that the Duelist saved her the trouble of looking for him if he lurked here the whole time ( in the dub , Julia remarks that if the Duelist doesn ' t want to talk , then he wants to Duel ) . Zuzu tries to reason with Julia ; she was still talking to him . Julia yells that she still has things to say to him first ( in the dub , Julia calls Zuzu a wannabe and warns her to stay out of the way ) . Zuzu yells that there still isn ' t proof the Duelist isn ' t the culprit . Julia says they ' ll know the truth if the Duelist uses Xyz Summoning . Upon hearing " Xyz " , Sora becomes intrigued . Julia insists the Duelist fight her to prove her convictions . Once again , Zuzu tries to convince Julia to stand down , but her bracelet glows , blinding everyone . When the light fades , the Duelist has vanished . Zuzu notes that it ' s just like before . Behind her , Yuya calls Zuzu ' s name . Yuya pants as he arrives at the warehouse and says Skip got worried , so he sent Yuya to look for her . He asks her why she didn ' t pick up her phone earlier . Julia accuses Yuya for being with the culprits . As Yuya is confused about why Sora is with the girls , Julia approaches Yuya and grabs him by the shirt collar , demanding where Marco is . Yuya is confused , but Julia is unconvinced . Yuya replies he ' s innocent ; he doesn ' t know who Julia is talking about . Zuzu separates the two and asks Yuya if he really didn ' t know ( in the dub , Zuzu tells Yuya the news that the masked Duelist was here earlier ) . Yuya is still bewildered about the current events . Zuzu repeats her memory of the masked Duelist disappearing just before Yuya arrived . Julia orders Yuya to get " him " , but Sora is quick to act . He points to his left that the culprit ran this way and urges Julia to hurry up and catch him . Julia pushes Yuya aside and runs at the direction Sora pointed . Yuya asks if the culprit really went that way and Sora admits that he lied , not wanting Julia to get in the way of his and Zuzu ' s training . Yuya repeats , " Training ? With Zuzu ? " and Sora says that Zuzu wanted to get stronger , but stops when he sees Zuzu stare at her bracelet , wondering if she wanted to keep the training a secret from Yuya , too . Yuya is surprised that she ' s learning Fusion Summoning for the Arc League Championship . He tells her that Nico found his four opponents to qualify . Zuzu looks up and congratulates him . Yuya says that now all he has to do is to win all four Duels and fight in the Arc League Championship . Sora is confused about the Championship , since this is the first time he heard about it and asks if he can participate too . Yuya thinks about it , before realizing that Sora didn ' t play 50 Duels with a 60 % win rate since coming to Paradise City . Sora is upset that he can ' t participate in the tournament because he wanted to Duel Yuya again ( in the dub , Sora is upset because no one wanted him to have fun ) . Yuya manages to remember another requirement : six wins in a row , which excites Sora . He asks Yuya to get Nico to arrange six Duels for him to win . Yuya agrees and looks at Zuzu , who sadly stares at her bracelet . He is proud of her for wanting to get stronger after her loss and recalls Declan ' s words of an evolution of Pendulum Summoning . He promises not to lose to Declan either ; he does not know how Declan can see past Pendulum Summoning , but he can , too . As Zuzu stares at her bracelet , she remembers that this is the second time that the masked Duelist appeared in front of her , then disappeared after the bracelet flashed . She wonders what ' s going on around here . At night , another masked Duelist spies on LID . Featured cards . The following cards appeared in this episode .
