Yu - Gi - Oh ! ARC - V - Episode 018 " Trapped in a Card " , known as " The Two Shadows of Rebellion " in the Japanese version , is the eighteenth episode of the " Yu - Gi - Oh ! ARC - V " anime . It first aired in Japan on August 10 , 2014 and in Australia on November 8 , 2015 . It became available with official subtitles via Crunchyroll on November 22 , 2016 . Summary . Claude informs Declan that Yuya Sakaki won his first match . Despite Declan making the effort to request that Yuya ' s entrance into the Junior Arc League Championship be approved , Yuya turned it down . Amused , Declan admits that he did something unnecessary , and muses that the fact that Yuya has chosen to carve out his own destiny is to be expected of the originator of Pendulum Summon ing . He asks if Yuya used Pendulum Summoning this time , and Claude confirms that a Summoning reaction was detected by the Control Room . Declan asks if there was any change to it , and Claude , surprised by the statement , states that there wasn ' t . Musing that Yuya " has yet to . . . " Declan gets up from his desk and looks out of the window . Claude speaks up , there ' s something that ' s been bothering him . Recently , they ' ve been detecting exceptionally strong levels of Fusion Summon ing in Paradise City . Though he initially assumed that it was the students , both Declan and Claude agree that it can ' t be compared to that of the students . Declan orders the Summoning monitored , and thinks that first it was Xyz Summon ing , and now it ' s Fusion Summoning ( in the dub , Declan thinks there are so many questions out there , but he knows the answer ) . At the harbor , Zuzu and Sora are Dueling . Sora controls " Fluffal Bear " , while Zuzu controls " Aria the Melodious Diva " and " Sonata the Melodious Diva " . She activates " Polymerization " from her hand , fusing " Aria " and " Sonata , " and she chants , " Enchanting melodies bloom in splendid glory and play for us a new harmony ! Fusion Summon ! " But instead of a monster , an error message pops up on her Duel Disk , and Zuzu panics , frantically asking why it didn ' t Summon her Fusion Monster . Sora asks if she remembered to put the monster into her Extra Deck , and Zuzu reacts in confusion . Sora patiently explains that he ' s told her a dozen ( thousand in the dub ) times that Fusion Monsters go in the Extra Deck , not the Main Deck . Shamefully admitting that that ' s right , Zuzu removes her Deck from her Duel Disk and sees " Schuberta the Melodious Maestra " in it . Behind a nearby warehouse , the masked Duelist is eavesdropping . Later , Sora points out that Zuzu had front - row seats for two of his Duels , and she should have been able to figure Fusion Summoning out from that . He could have beaten the Duelists without Fusion Summoning , but did so anyway so that Zuzu could learn . Zuzu apologizes ( in the dub , Zuzu mutters she doesn ' t have what it takes ) , and Sora jumps down from the container he was sitting on . He comments that he bets that she was thinking about " him " again , wasn ' t she ? Zuzu blushes and looks away , and Sora proclaims that he knew it ; that ' s why Zuzu ' s been Dueling so absent - mindedly ( in the dub , Sora comments that the Duelist has had Zuzu ' s attention ) . He asks who the Duelist is , but Zuzu doesn ' t know , so instead Sora asks to confirm that it was the second time that they ' d met ( in the dub , Sora also asks for the Duelist ' s name ) . Zuzu admits that the first time had been here as well , when he ' d stepped in to save her from Sylvio , telling her that he didn ' t want her to get hurt . Sora asks if that ' s how the masked Duelist stole Zuzu ' s heart , prompting an embarrassed response from Zuzu . Fortunately for her , Sora doesn ' t press the issue further and admits that he ' s excited himself , as the Duelist seems like a pretty interesting guy ( in the dub , Sora thinks the Duelist ' s mask was how Zuzu couldn ' t get to know the Duelist ) . If Julia hadn ' t butted in , he might have been able to Duel the masked Duelist . Taking a large bite out of a chocolate bar , he comments that that was really disappointing ( in the dub , Sora says next time , the Duelist won ' t get off that easily ) . Zuzu protests that Sora can ' t Duel him , as he ' s dangerous . She remembers the Summoning of " Dark Rebellion Xyz Dragon " and wonders why the Duelist was able to create actual shockwaves outside of an Action Field , and why he told her that he didn ' t want her to get hurt anymore . The masked Duelist remembers standing in a destroyed cityscape , claiming that he didn ' t want to hurt anyone anymore . He hears something up to his right above him looking up to see a white - suited Duelist sitting astride a Duel Runner . The Duel Runner projects its screen and Card Zones , and the Dark Duelist activates his own Duel Disk . The White Rider ramps off the building and charges towards the Dark Duelist . An explosion of dust rises up , the Dark Duelist emerging and Summoning his " Dark Rebellion Xyz Dragon " ( in the dub , he further tells his dragon to prepare to battle ) . Swerving away from the Dark Duelist , the White Rider Summons his own monster , a a glowing white dragon , and both Dragon s charge and clash . The Duelist in the blue coat who had been surveying the Leo Corporation runs up with four of his fellows , and the White Rider grits his teeth in annoyance before fleeing . The second Duelist asks the Dark Duelist where Lulu is , but the Dark Duelist just shakes his head . The second Duelist curses ( in the dub , he wonders where his sister could be ) . Back in the present , the masked Duelist muses " Lulu . " Then he hears a cry from Zuzu , whose bracelet has activated again . The pink light fades , and Zuzu and Sora hear Yuya ' s voice , commenting that he knew they ' d be there . As he asks Zuzu why she can ' t practice at the You Show Duel School , since it ' s getting annoying being sent by her father to find her , he passes the alleyway where the masked Duelist was hiding . In another part of the city , the masked Duelist opens his eyes and he wonders if he got warped again as he looks around at the skyscrapers . He hears an explosion and runs around a corner to see Herk Dueling the masked Duelist ' s comrade . Tio gasps that the other Duelist is strong , as he faces off against the Duelist ' s monster . The masked Duelist gasps his comrade ' s name : Shay . At Yuya ' s home that night , Yoko has just been told by Yuya about Zuzu ' s bracelet , as their six pets eat around them . Yuya explains that whenever it shines , he always shows up , though he doesn ' t believe it to be true . Sora claims that the bracelet is like a radar to find Yuya , and Yuya irritably tells him not to talk about people like they ' re lost pets , then asks why Sora is eating here . Sora replies that it ' s because Yuya ' s older sister ' s - his mother ' s , he means - cooking is so good ( in the dub , Sora says it isn ' t his fault that Yoko is the best cook on the planet ) . Flattered , Yoko reassures Sora that she ' s doesn ' t mind , and besides , it ' s more fun if they eat dinner together ( in the dub , Yuya asks why everything has to be so healthy , while Yoko nonchalantly replies that it looks delicious ) . Recognizing the food , Yuya asks if the dishes are all " his " , and Yoko confirms that they are Reed Pepper ' s recommended brain food , as she ' s heard that Yuya ' s next Duel will test his wits . Sora gives thanks for the food , and immediately dumps chocolate syrup on his sardines , much to Yuya ' s disgust . Yoko points out that sardines are full of Omega - 3 ' s that are good at increasing concentration and memory . And since Flavonoids in chocolate accelerate blood flow to the brain , why not ? ( in the dub , Yoko chides Yuya , since people have different tastes in food and it isn ' t right to judge them for it ; she finds it charming that Sora puts peanut butter on his omelettes and ketchup on his ice cream ) Yuya muses that he guesses it ' s alright if the one who ' s eating it enjoys it , and asks Sora if he ' s heard who his next opponent is . Sora has no idea , and isn ' t interested , claiming that there ' s no way he ' d ever lose to anyone . Yuya warns him not to let his carefree mindset trip him up later . Sora replies that he should say the same to Yuya ; if he isn ' t careful , someone is going to take Zuzu away from him . Yuya is thoroughly confused , pointing out that it ' s not like Zuzu is his girlfriend or anything . In her own house , Zuzu yells at her father to stop joking around with her . Skip protests that he keeps telling Zuzu that she ' s had that bracelet since she was born . Zuzu furiously asks in what world does a baby come out with a bracelet stuck on their wrist , and Skip tries to calm her , but Zuzu ' s had enough , as she storms off and locks herself in her room . Skip points out that he also heard that she was getting lessons in Fusion Summoning from Sora , and if she ' s doing special training for the Junior Arc League Championship . Skip asks why she couldn ' t do it at their place ; is his hot - blooded teaching not enough for her ? But Zuzu doesn ' t answer ; she sees the masked Duelist in her mind again , and she asks why she keeps seeing his face . She flops down on her bed and mutters that even though she needs to master Fusion Summoning as fast as possible to get stronger , if she ' s like this , no matter how hard she tries , she ' ll be a liability for You Show Duel School . Zuzu removes her bracelet and raises it into the air , but clutches it in her hands and bends over , wondering miserably what ' s wrong with her . In Declan ' s office the next day , he reacts in surprise to two cards on his desk . His mother has explained to him that they were sent anonymously to them that morning . The cards bear the images of Marco and Herk . Henrietta asks what the perpetrator is doing , sending them card of two of LID ' s ace Duelists . Declan explains that there was another powerful Xyz Summoning reading picked up the previous day , and shortly after , they received a report that Herk had disappeared as well . To think that they would be sealed inside of a card . . . Henrietta is shocked , and Declan admits that it ' s the first time that he ' s witnessed this in reality . But this means that Marco and Herk are alive . Henrietta asks whether they can be saved , but Declan admits that they can ' t with their current power . He notes that this raises another question . There have been three incidents so far ; the first involving Sylvio , but he was not sealed inside a card . But both the second and the third , Marco and Herk , were sealed . This suggests that there are two perpetrators . Henrietta is shocked at the prospect . Claude ' s voice is heard , begging the congressman to wait . The doors crash open , as Curio asks Declan what he ' s doing loafing around ( in the dub , Curio says he ' s an important man who can ' t be kept waiting ) . Claude begs him to wait outside , but Curio tells him to can it ; he ' s got business with the Director . Claude protests that Curio doesn ' t even have an appointment , and Curio asks if there ' s a problem with the future city president coming to see the director of the election committee ( in the dub , Curio threatens Claude with an appointment to his lawyer if he doesn ' t stop harassing him ) . Declan tells Claude to let Curio stay . Curio comments that he heard they had another incident . Henrietta tries to play dumb , but Curio isn ' t fooled , as he warns them not to underestimate the information network of the future mayor ; he ' s heard that first a teacher , then the ace of the top team got taken out . Henrietta is a little flustered , but Declan admits that it ' s true . Curio angrily asks why they ' re sitting there folding their arms ( in the dub , Curio asks why the perpetrators aren ' t arrested yet ) . Declan reassures him that they ' re currently investigating the perpetrator . Curio protests that his son already testified that Yuya Sakaki attacked him , slamming down a photo of Yuya on the desk . Declan asks if Sylvio is still saying that , and Mr . Sawatari admits that he hasn ' t seen Sylvio since he got out of hospital , but neither has he heard anything about the testimony changing . He points out that Henrietta had even agreed to handle things and leave everything to her , so why are they sitting around and letting the perpetrator cause a second and third incident ? He can ' t keep quiet about this ; he ' s got to get the cops moving by his own hands to protect the order in Paradise City and catch Yuya Sakaki . Declan asks him to please hold on a second , but Curio isn ' t waiting . Declan loses his temper as he slams his hands on his desk and gets to his feet , intimidating Curio . Declan warns Curio that he said that it was under investigation ; they aren ' t just twiddling their thumbs here , and have risen the efforts in both Leo Corporation and LID to find the perpetrator . Curio protests that he told them that the perpetrator is Yuya Sakaki , but Declan defensively replies that Yuya is no criminal . They will surely find the real perpetrator ; until then , he ' d like Curio to watch quietly . Huffing , Curio snatches up Yuya ' s picture , claiming that he won ' t accept failure from them and storming off . Declan orders Claude to raise the level of alert in the inner city . The cards are clearly meant to provoke them , and they need to make sure that they ' re ready to handle any incident . He orders Claude to have the cards analyzed thoroughly , in order to save them , no , all Duelists in Paradise City . In the streets below , Yuya is yawning , having watched quiz shows all night . He ' s supposed to be training his mind for a battle of wits , but can ' t think now because he ' s so sleepy . He overhears Curio screaming at three LID top - team members , asking if they ' re deaf . He ' s an active city councilor , and will be the town mayor soon , the most powerful person with the most influence . A woman asks her friend who he is , and her friend replies that he ' s that Sawatari guy from the city council . The first woman expresses her disgust that Curio is carrying on like that even though he isn ' t the mayor ( in the dub , the woman whispers that when Curio does become mayor , she ' d buy earplugs ) . Curio tells the LID students that that means they have to follow his orders , not the Director , not the CEO , but him , the mayor ( in the dub , Curio makes various demands on when he becomes mayor and asks why it ' s hard to understand that the LID has to serve him ) . Yuya asks if that ' s Sylvio ' s father , but then he remembers the time ; if he doesn ' t hurry , he ' ll be late for his meeting with Nico . He runs off , and Curio sees him in the reflection of a shop window . He pushes the LID students forward and yells that Yuya is the perpetrator they ' ve been looking for . He forces the students to hurry up and catch him when they hesitate . They run after Yuya , with Curio screaming for Yuya to stop . Yuya quickly realizes he ' s being chased , and when accused by Curio of hurting Sylvio , protests that he didn ' t do it . He runs around a corner and into an alleyway , and runs towards Shay , who has his Duel Disk activated and a Winged - Beast - Type monster above him . As soon as he sees the LID badges on their collars , Shay declares himself their opponents . Yuya passes Shay in shock , and stops behind him , asking what ' s going on . The LID top team realize that Shay may be the person who attacked Herk and Marco , but Curio doesn ' t get it , asking what Shay ' s deal is . Shay warns them that he will start if they do not , and the LID top team try to contact HQ . Curio yells at them to get Yuya . Shay Summons " Raidraptor - Vanishing Lanius " from his hand , and a copy of the monster on the field appears . When it ' s successfully Summoned , he can Special Summon another from his hand , and he does so . Yuya realizes something as Shay overlays all three " Vanishing Lanius " , and as the Xyz Materials spiral into the Overlay Network , the top - team declare that there ' s no doubt ; Shay is the one who attacked Herk and Marco ( the top - team ' s remarks are cut from the dub ) . Shay declares an Xyz Summon , which is picked up in the Leo Corporation Control Room . A female technician claims that the energy readings are at maximum , then even greater than that , matching the previous reports . A gust of wind blasts Curio off his feet as the same monster that Shay used against Herk appears . Curio grabs onto a stair railing and struggles to hold on , while Yuya is blasted into a wall , and falls unconscious in some rubbish bags . The claws of Shay ' s monster slice into the stone of the overpass , leaving deep gouges , and Curio is blown away again . Cards float down by his face , containing the trapped top - team , and Curio screams in terror and scrambles to flee . The cards are blown away by the wind . Yuya wakes to see Nico snapping his fingers at him , and bolts to his feet in terror . Nico asks Yuya what is wrong , and Yuya screams " It was horrible ! Xyz ! Xyz ! " Confused , Nico asks Yuya if there ' s something wrong with Xyz Summoning ( in the dub , Nico says he has no idea what Yuya is talking about ) . Yuya protests that a terrifying monster showed up and blew everyone away . Nico asks where those people are , and Yuya tries to point out the people that chased him , only to realize that they ' re gone . Nico asks Yuya what a monster would be doing attacking people not even in a Duel Stadium , but in the middle of the city . Is Yuya sure that he didn ' t just dream it ? He asks if Yuya ' s sure that he didn ' t just dream it , as Nico found Yuya sound asleep in the road . Yuya apologizes , as he stayed up late , and Nico leads him off to meet his second opponent , commenting that Yuya can ' t keep doing this if he ' s aiming to be a pro ; managing one ' s health is an important responsibility , you know . As he leads Yuya away , the gouges left by Shay ' s monster are still clearly visible in the overpass . Featured Duel : Zuzu Boyle vs . Sora Perse . Duel already in progress .
