Yuya narrates that the Arc League Championship has finally begun . The first to get a win for You Show Duel School was Frederick , in a Duel that would give you the shivers . Frederick modestly claims that it wasn ' t that much . Yuya recaps that Ally was up next , but , and Ally finishes that she lost . Frederick comments that Riley was pretty weird , wasn ' t he ? Ally admits that he seemed really nervous at the start , but she was shocked when he Fusion Summoned . Tate muses that it makes one wonder . Yuya states that Zuzu is up next , and Zuzu explains that her opponent is her fated rival who she lost to in her match against LID , Julia Krystal . She states that she can ' t lose this Duel , and both Yuya and Skip encourage her to win . An announcer details the Arc League Championship to the audience as a festival of Duelists and the gateway to being a Pro Duelist . Now all of their burning feelings gather here . As the announcer declares , " Let ' s Blast It ! " in English , Zuzu enters the arena . The kids and Yuya cheer her on . Julia walks forwards and straps on her Duel Disk . Zuzu wonders why when Julia was hostile to Shay Obsidian , she now claims that Shay has always been a member of LID . Julia notices Zuzu ' s distraction , and she comments that Zuzu ' s eyes have no luster . Zuzu flinches as the mental equivalent of a 10 - ton weight drops on her head , and she protests to herself angrily , remembering that during their last Duel , she was distracted due to confusing Yuya with Yuto and she lost , and she won ' t let that happen again . She tells Julia that she ' ll see a different side of Zuzu in this match than she did before , and Julia comments that that ' s fine . Since this is a tournament match , it would be boring if Zuzu didn ' t even do that . Nico Smiley thanks the audience for coming and announces the matchup : You Show Duel School ' s Zuzu Boyle which teaches Entertainment Duels vs . the day ' s fiercest competitor , Leo Institute of Dueling ' s Julia Krystal . Skip tells Zuzu to burn and be hot - blooded , and Yuya urges her to get her revenge . Sora Perse notices Shay standing to the side , watching the Duel , and he smiles . Nico announces the Action Field , " Infinite Bridge " . A network of crisscrossing railed walkways appears and elevates the two Duelists above the ground , as Nico states that one misstep will mean a headfirst drop into the abyss , and he wonders which of these budding Junior Duelists will bloom in this unnerving Field . Zuzu declares , " Duelists locked in battle ! " Julia declares , " Kicking against the earth and dancing in the air alongside their monsters ! " " They storm through this field ! " Zuzu cries . Both of the girls chant , " Behold ! This is the newest and greatest evolution of Dueling ! ACTION ! DUEL ! " The Action Card s scatter , and Julia goes first , activating " Gem - Knight Fusion " from her hand . She fuses " Gem - Knight s " in her hand to Fusion Summon a " Gem - Knight " Fusion Monster . Zuzu thinks that it ' s just like she expected ; Julia is going to perform a Hand Fusion on her first turn like last time . Fusing " Gem - Knight Sapphire " , " Gem - Knight Crystal " , and " Gem - Knight Garnet " , Julia chants , " Strong - willed blue ! Crimson truth ! Eye of quartz ! Combine to bring forth a new dazzling radiance in a whirlpool of light ! Fusion Summon ! Appear now ! One who illuminates everything with its supreme radiance ! Gem - Knight Master Diamond ! " Zuzu asks if Julia ' s bringing her ace out already and Julia smiles . She explains that " Master Diamond " gains 100 ATK for every " Gem - " monster in her Graveyard . Yuya and Gong note that Julia has three " Gem - " monsters in her Graveyard , so its ATK will increase by 300 , which brings " Master Diamond " up to 3200 ATK . Set ting a card face - down , Julia ends her turn . Telling Zuzu that it ' s her turn now , Julia urges Zuzu to show her just how much Zuzu has changed . Zuzu declares her turn , looking at Sora and nodding , and draws . As Sora and Shay look on , Zuzu immediately activates " Polymerization " from her hand , much to the shock of both the crowd and Julia . Fusing " Aria the Melodious Diva " and " Sonata the Melodious Diva " from her hand , Zuzu chants , " Echoing melodious voice ! Flowing melody ! With guidance of the baton , gather your power ! Fusion Summon ! Now come here to the stage ! Schuberta the Melodious Maestra ! " Shay flinches in horror at seeing Zuzu Fusion Summon , and Ally cheers that Zuzu pulled it off . Skip cheers that Zuzu is dazzling today . Zuzu activates the effect of " Schuberta " ; once per turn she can banish all of the cards used to Fusion Summon a monster from the Graveyard , using " Chorus Break . " Yuya cheers that with less " Gem - " monsters in the Graveyard , " Master Diamond ' s " ATK is reduced , and Sora adds that it also prevents " Gem - Knight Fusion ' s inherent recycling effect , musing that Shay already knows this much . Zuzu further reveals that " Schuberta " will gain 200 ATK for each banished card until the End Phase . " Schuberta " rises to 3200 ATK and " Master Diamond " falls to 2900 ATK . Declaring her Battle Phase , Zuzu attacks " Master Diamond " with " Schuberta ' s " " Wave of the Great " , and Julia leaps out of the way , onto another bridge as " Master Diamond " is destroyed and Julia falls to 3700 LP . Zuzu Sets two cards and ends her turn , the ATK of " Schuberta " returning to normal . Kit is impressed that You Show Duel School are doing so well , and Dipper points out that Julia has no cards in her hand . Julia declares her turn and draws , getting " Brilliant Fusion " . She admits that she ' s impressed that Zuzu can Fusion Summon , but if that ' s all she can do it won ' t stand a chance against Julia . Zuzu tells Julia to quit bluffing as she can ' t fuse with just one card in her hand . Julia activates the Continuous Spell Card " Brilliant Fusion " , allowing her to use monsters in her Deck to Fusion Summon a " Gem - Knight " Fusion Monster . Yuya is shocked that Julia can fuse monsters in her Deck , and Sora is impressed . Julia sends " Gem - Knight Alexandrite " , " Gem - Knight Emerald " , and " Gem - Knight Obsidian " to the Graveyard , and chants , " Gem with facelets of day and night ! Brilliant emerald of good fortune ! Sharp jet - black darkness ! In a whirlpool of light , combine to bring forth a new dazzling radiance ! Fusion Summon ! This is my true ace ! Dazzling lady , Gem - Knight Lady Brilliant Diamond ! " Kit tells Julia to show them the power of LID ' s Fusion Summoning . " Brilliant Diamond " stands with 3400 ATK , but the effect of " Brilliant Fusion " reduces its ATK and DEF to zero . However , by sending a Spell Card in her hand to her Graveyard , Julia can return its stats to normal until the end of her opponent ' s turn . She takes off at a run and Zuzu follows , much to the confusion of the kids . Yuya frantically explains that Julia is planning on using Action Cards to restore the ATK of " Brilliant Diamond " . Zuzu activates a Trap Card , " Musical Mayhem " , attempting to use its effect to inflict 800 damage to Julia for every " Melodious " monster Zuzu controls to block Julia . Green lightning strikes and Julia is thrown off the bridge , her LP falling to 2900 , but grabs a pole and uses her momentum to swing around and grab the Action Card , " Evasion " . Nico praises the LID elite ' s brilliant movement as Julia sends the card to her Graveyard , restoring the ATK of " Brilliant Diamond " . Julia attacks , and " Brilliant Diamond " shreds the sound waves that " Schuberta " fights back with before destroying it and reducing Zuzu to 3000 LP , throwing her over the railing . Yuya is horrified , but Zuzu manages to grab the railing . Nico comments that that was a close one . Kit admits that he was worried for a second there , and Dipper muses that it looks like Julia is back to her usual self . Zuzu steps primly back onto the walkway , and she looks up at Julia , who asks if Zuzu sees that this is the difference between their strengths . She ends her turn . Zuzu declares her turn , thinking that if Julia gets another Action Card , Zuzu will be at even more of a disadvantage . She draws " Canon the Melodious Diva " and then Sets it . Julia comments that it looks like Zuzu doesn ' t have any options left . Zuzu looks at the " Fusion Cycle " Trap Card in her hand , thinking that if Julia is the Duelist that Zuzu thinks she is , then she ' ll . . . She Sets the card and ends her turn . The kids are surprised that she ' s ended her turn just like that , but Sora reassures them that Zuzu should be able to handle this much , since he ' s taught her the fighting style of a true Fusion Summoner . Julia begins her turn and draws . The ATK of " Brilliant Diamond " returns to 0 , and both Julia and Zuzu sprint for an Action Card , Zuzu refusing to let Julia get to the card . Julia retorts that she won ' t let Zuzu stop her and Summons " Crystal Rose " . " Crystal Rose " can be treated as any monster for a Fusion Summon , and Julia treats it as " Gem - Knight Tourmaline " . Rays of light refract around " Crystal Rose " which transform into " Tourmaline " . Then Julia activates the effect of " Brilliant Diamond " , allowing her to Fusion Summon using only one Fusion Material . Zuzu is shocked that Julia can fuse with a single material . Three diamonds emerge from " Brilliant Diamond ' s " chest and surround " Crystal Rose " in energy as Julia declares , " Grind Fusion ! " She chants " Come forth , bewitching and dazzling splendor ! Gem - Knight Zirconia " , who leaps in front of Zuzu to block her path , allowing Julia to grab the Action Card without interference . The kids bemoan the card ' s loss . Sending " Miracle " to her Graveyard , Julia restores the ATK of " Brilliant Diamond " to normal again , as Yuya observes grimly . Julia declares her Battle Phase and attacks with " Zirconia " . Zuzu flees as " Zirconia " shatters her Set " Canon the Melodious Diva " with a single punch , sending Zuzu rolling across the walkway . Julia walks up to Zuzu , telling her that now the only monster she had protecting her is gone . This will finish it . Julia declares a direct attack with " Brilliant Diamond " , who strikes from high . Zuzu activates a Trap Card , " Fusion Cycle " . It Special Summons a monster that was used for a Fusion Summon this turn from her opponent ' s Graveyard in Attack Position to Zuzu ' s field and prevents it from being destroyed this turn , so Zuzu brings out " Crystal Rose " . Julia is shocked that Zuzu was able to Summon a monster from Julia ' s own Graveyard , but she points out that Zuzu will still take damage and she continues her attack regardless , and " Brilliant Diamond " strikes " Crystal Rose " . Zuzu ' s LP takes a large hit , falling to 100 . Julia ends her turn , commenting that it was quite lucky for Zuzu that Julia Fusion Summoned that turn . Zuzu replies that it wasn ' t luck , since she knew that Julia has pride as a Fusion user and would likely try to finish her off with a Fusion Monster , and that would protect her LP and give her the hope that she needed . Julia muses that Zuzu is quite talkative for someone who only survived by the skin of her teeth , and suggests that she prove to Julia next turn that Zuzu can do something aside from pointless struggling . Zuzu replies that she plans to and prepares to draw . She remembers Yuya returning her " Polymerization " card , telling her that with this he ' s trying to change herself into a different Zuzu up until now , and remembers Yuto telling her that the her that is trying to become stronger for her friends and change herself isn ' t wrong . Zuzu vows that she will become stronger for her friends and this is her resolve . She draws dramatically , telling Julia that she ' ll show her her radiance right now . She Summons the card that she drew , " Soprano the Melodious Songtress " . The effect of " Soprano " allows Zuzu to fuse monsters from her hand and field for use in a Fusion Summon , and Julia realizes in shock that Zuzu is going to use " Crystal Rose " . Zuzu uses the effect of " Crystal Rose " to treat it as " Mozarta the Melodious Maestra " , and " Crystal Rose " sends out its light rays , refracting into " Mozarta " . The crowd are amazed , comparing it to an angel being born from a flower , and Zuzu fuses her two monsters , chanting , " Angel ' s song ! Supreme genius ! With the guidance of the baton , gather your power ! Fusion Summon ! Now come here to the stage ! Sing the song of victory ! Bloom Diva the Melodious Choir ! " The crowd is in awe , and Yuya says that it ' s Zuzu ' s new ace monster . Dipper and Kit are shocked at the Fusion Summon using Julia ' s cards without a Fusion Spell . Zuzu attacks " Zirconia " with " Bloom Diva " , much to Frederick ' s surprise , since " Bloom Diva " only has 1000 ATK . As " Zirconia ' s " eyes glow red and it clashes with " Bloom Diva " , who rotates her arms frantically to block the blow , Zuzu explains that " Bloom Diva " is not destroyed while battling Special Summoned monsters and her opponent takes the battle damage that she would have taken , and then that monster is destroyed . She declares , " Reflect Shout ! " and " Bloom Diva " sings a sonic wave that destroys " Zirconia " . Julia ' s LP drops to 1000 , and she gets up shakily , claiming that now Zuzu has done it , and this will be her downfall . She activates her Trap Card , " Brilliant Spark " , which will deal the ATK of a destroyed " Gem - Knight " monster to Zuzu as damage . Gong and Yuya are horrified , knowing that Zuzu will lose . Zuzu promptly responds with her own Trap , " Melodious Illusion " , which will negate the activation of a Trap Card and then allow a " Melodious " monster to attack again . The kids cheer , but Frederick notices something . Julia slides down a pole , explaining " Brilliant Spark ' s " second effect ; she can send a Spell Card from her hand to her Graveyard to prevent the activation of her card from being negated . As Zuzu leaps off her own walkway , Yuya panics , knowing that Zuzu will lose if Julia gets to the Action Card first . Julia reaches for the card . . . and Zuzu dives past , grabbing it first . " Bloom Diva " swoops in and catches Zuzu as Nico narrates the twist . Deposited on a lower platform , Zuzu tells Julia that You Show Duel School can ' t lose when it comes to Action . Julia can ' t believe that Zuzu would jump like she did , and Zuzu explains that being one with your monsters is how You Show Duel School Duels . She uses the effect of " Melodious Illusion " to have " Bloom Diva " attack again , and " Bloom Diva " then uses her " Reflect Shout " to destroy " Brilliant Diamond " . Julia ' s LP falls to zero , and the attack blasts her into the air , much to Zuzu ' s horror . Fortunately , " Bloom Diva " saves Julia , much to Julia ' s surprise . Zuzu smiles and nods at her , and Julia looks away with an irritable blush . Kit and Dipper heave a sigh of relief that Julia is all right , and Nico announces Zuzu as the winner . The kids congratulate Zuzu , as does the over - emotional Skip , as Yoko and the kids smile awkwardly . Yuya tells Zuzu that she did it . Sora smiles , thinking that now Shay knows how amazing he is , but when he looks back to where Shay was standing , the Xyz user has vanished , much to his anger . Tate looks at Sora in surprise as Sora asks what ' s with Shay , don ' t tell him Shay left before the best part . After the day ' s Dueling , everyone congratulates Zuzu on her win . Sora comments that it was a given since he taught her . Julia then approaches Zuzu , warning her not to lose in the tournament , since Julia couldn ' t handle losing to someone who didn ' t win the tournament . She digs in her pocket and hands the " Crystal Rose " card to Zuzu , telling her that she ' ll need it to shine like she did in their Duel today , and warning Zuzu that she won ' t forgive her if she loses . Zuzu waves at Julia , thanking her and telling her that she ' ll be sure to shine brighter . Featured Duel : Zuzu Boyle vs . Julia Krystal .
