Yu - Gi - Oh ! ARC - V - Episode 030 " Gong the Strong " , known as " The Tested Steadfast Heart " in the Japanese version , is the thirtieth episode of the " Yu - Gi - Oh ! ARC - V " anime . It first aired in Japan on November 2 , 2014 and in Australia on December 6 , 2015 . It became available with official subtitles via Crunchyroll on November 22 , 2016 . Summary . Gong remembers his encounter with Grizzlepike in his childhood , thinking that his former senior disciple is his first opponent as he sits cross - legged with steaming riceballs on his shoulders . Not only did he humiliate Yuya , but he dissented against the teachings of the Strong Dojo and left disgracefully . He gets fired up , claiming that he cannot lose this match . His father throws open the Dojo doors , proudly declaring that that ' s what he wants to hear . Holding out a black sash to Gong , his father tells him that as he tightens this new sash , he must also temper and tighten his steadfast spirit in preparation of this next battle . Strapping the sash on in place of his white one , Gong replies that he understands . As an announcer describes the Arc League Championship as a festival and gathering of Duelists and their burning feelings , Yuya sits outside , thinking that after Zuzu ' s victory yesterday , it ' s finally his turn . Gong , him , and Sora will all win and get to the next round he says out loud . A bald boy crashes into him , yelling at him to look out and dropping a white sash , protesting that it ' s Gong ' s for the match today . Yuya recognizes the sash , but a pink - haired boy with a Mohawk snatches up the sash and takes off . Yuya and the bald boy run after him . Ally and Frederick urge everyone else to hurry up , since Gong ' s match is starting soon . Zuzu looks around in confusion , since Yuya had promised to meet them there , and Tate gasps , pointing to see Yuya sprinting off , as Sora observes . As he pursues the thief , Yuya wonders why he ' s stealing Gong ' s sash . The bald boy explains that the thief ' s probably one of Grizzlepike ' s friends , who will resort to any means to win . Yuya grits his teeth in anger , and the boy asks if Yuya has a match soon . Yuya replies that he can ' t let that stop him . Gong comes first . The bald boy smiles upon hearing that . In the arena , Nico Smiley welcomes the audience to the second day of the tournament , and he introduces the competitors . While he doesn ' t belong to any known school , this Duelist qualified for the Junior Youth Championship with a six - win streak : Grizzlepike who stomps into the arena and grins . His opponent is the successor to the Heavystrong Dueling style of the Strong Dojo , Gong Strong . Gong stands with his back to Grizzlepike , baring his sash , which he compliments , asking if Gong ' s father gave it to him . Gong reminds him that the master of the Dojo always gives them a new sash before a pivotal match , and that is the tradition of the Strong Dojo . Snickering , Grizzlepike states that he ' s taken advantage of that so - called tradition , and Gong raises his eyebrow in surprise . Nico suggests that they select the Action Field , and it ' s chosen as " Calamity Cove " An island covered in dense forest appears , with Gong and Grizzlepike standing in a clearing . Grizzlepike remarks that the dense forest is quite the coincidence , since he ' s sure that Gong ' s friend is in a dense forest right now . Gong asks what Grizzlepike said , turning around in shock . Yuya and the bald boy reach a clearing , and the thief and two other boys step out of the trees . Yuya is shocked at being ambushed , and even more when the bald boy abandons him , calling him an idiot for falling for it . The thief tells Yuya that he ' ll be keeping them company for a little while , and Yuya grits his teeth . Gong furiously and rudely yells at Grizzlepike ; how could he do something so underhanded . The former pupil laughs , asking Gong what happened to his unshakeable spirit . He comments that that ' s all his so - called Heavystrong spirit is worth . Using any methods in order to win is what the truly strong do , which is why he cut his ties to the Strong Dojo . Grizzlepike sneers that he wonders if Yuya is all right . He suggests that Gong hurry up and defeat him , unless he ' s going to spout nonsense about Yuya being more important than him and surrender the match now . In the stands , Zuzu irritably phones Yuya to see where he ' s run off too , and she contacts him as he stands with his Duel Disk activated . Yuya tells Zuzu to tell Gong not to worry , and that Yuya will get Gong ' s sash back . Zuzu is quite confused as Yuya hangs up . Down in the stadium , Gong declares that upon the honor of his Dojo , he cannot surrender without a fight . Grizzlepike tells him to struggle all he wants , and they kick out at one another , sparring as Gong chants , " Duelists locked in battle ! " Blocking Gong ' s strike , Grizzlepike yells , " Kicking against the earth and dancing in the air alongside their monsters ! They storm through this field ! " The Duelists push against one another , as Gong yells , " Behold ! This is the newest . . . " and " Grizzlepike " " . . . and greatest evolution of Dueling ! " They both yell " ACTION ! " and they , Yuya , and Grizzlepike ' s friends all yell , " DUEL ! " The Action Card s scatter and Grizzlepike takes the first turn . He Summons " Granite Battleguard " and activates its effect ; since it was Normal Summon ed he can Special Summon " Boulder Battleguard " from his hand . Nico reacts with surprise , calling it a throwback for him , since these are the monsters that the Sledgehammer used . Setting a card , Grizzlepike ends his turn , telling Gong that it ' s his turn , and if he doesn ' t hurry up , his friend will be beaten to a pulp . Retorting that he was already planning to beat Grizzlepike with one attack , Gong draws explosively . Since his opponent controls two or more monsters , he can Special Summon " Superheavy Samurai Big Waraji " from his hand . " Big Waraji " can be treated as two Tribute s for the Tribute Summon of a Machine - Type monster , so Gong Tributes it to Tribute Summon " Superheavy Samurai Big Benkei " in Defense Position . As " Big Benkei " appears from a column of green light , Nico explains to the audience that " Big Benkei " can be Summoned in face - up Defense Position , while Tate excitedly recalls that " Big Benkei " can attack with its 3500 DEF . Ally cheers that it can take out either of those " Battleguards " in one hit , while Frederick gets his shivers , and Sora points out that Gong won ' t be ending it in one attack though . Zuzu meanwhile , wonders if Grizzlepike was taking about Yuya when he referred to a friend being beaten to a pulp . Gong continues his turn , explaining that when he has no Spell / Trap Card s in his Graveyard , he can send a " Superheavy Samurai " monster from his hand to his Graveyard to Special Summon the Tuner monster , " Superheavy Samurai Trumpter " from his hand . Discarding " Superheavy Samurai Gigagloves " , he Special Summons " Trumpter " in Defense Position . Ally cheers at the sight of the Tuner monster , which will allow Gong to Synchro Summon . Pike laughs , calling it naive . He activates a Trap Card , " Battleguard Sorcery " , which since he controls a " Battleguard " monster and his opponent controls at least two monsters , allows Grizzlepike to take control of one of Gong ' s monsters . Flaming pillars erupt around the " Battleguards " , who perform a tribal dance and clash their clubs , sending out a shockwave that takes control of " Trumpter " , who joins the " Battleguards " in their dance . Tate and Frederick bemoan the monster ' s theft and Grizzlepike laughs , explaining that he ' d already researched that Gong had won his way into the tournament using Synchro Summoning . Matches aren ' t just decided within the field , and anything could be happening outside of this field right now . If Gong doesn ' t hurry up and go , who knows what will happen to his beloved friend ? Gong utters Yuya ' s name and Zuzu gasps . Yuya meanwhile , rides on " Performapal Hip Hippo " , urging Gong to wait , as he will be right there . Nico recaps , explaining that Gong had brought out a Tuner monster and aimed for a Synchro Summon , but Grizzlepike has taken control of the key card that he needed . Julia comments to a frustrated Kit that his so - called disciple is doing terrible , and Dipper admits that he didn ' t expect to see Gong ' s monster get taken so easily . Kit furiously asks if Gong is trying to make him look bad , warning him that Kit won ' t accept a loss . Gritting his teeth , Gong tells himself that he needs to hurry up , and he immediately attacks " Granite Battleguard " with " Big Benkei " . Grizzlepike activates the effect of " Boulder Battleguard " , allowing him to negate an attack targeting a " Battleguard " monster , and the " Battleguard " spins its club to block the plume of fire that " Big Benkei " sent its way . Ally gasps that the attack got cancelled , and Gong swears and slams his fist into the ground , roaring that he doesn ' t have time for this . Kit wonders in concern why Gong is panicking . Grizzlepike sneers , asking what this is , is Gong frustrated , is he panicking ? Gong got betrayed by his monster and he doesn ' t know what ' s happening to his beloved friend . Grizzlepike bets that Yuya is thinking that Gong has betrayed him too , even though he believed that Gong would come and save him but he won ' t , and Gong continues to punch the ground , yelling his friend ' s name . Grizzlepike snickers , mentally urging Gong to suffer and panic , since the more he does , the more his spirit and Dueling will be sullied . He yells that he ' ll prove how fragile Gong ' s Heavystrong spirit is . Zuzu calls out to Gong , urging him to believe in Yuya , explaining that Yuya told her to tell Gong that he ' d get Gong ' s sash . Gong is surprised , and Zuzu reminds him that Yuya isn ' t the same Yuya as he was before , and he can fight on his own . Gong ' s father leaps onto the fence beside Zuzu , telling his son that now is the time for a Heavystrong spirit , and he must believe in his friend as well as in himself . The words reach Gong , but Pike , realizing that they got in contact with Yuya , comments that it ' s pitiful when " that weakling " acts like he ' s something else . Gong rises to his feet , declaring that Yuya is no longer a weakling , as Yuya is seen still Dueling , vowing to get the sash back . Gong replies that Yuya will definitely come back , agreeing with Zuzu that Yuya isn ' t the same as he was three years ago and can fight on his own , and Gong declares that now that he knows that his friend is safe , his spirit will waver no more . Gong will follow his Dueling ways , and kanji reading " Steadfast as a Mountain " appear around him ( the Japanese name of Gong ' s Heavystrong Dueling style is " Steadfast " ) . Skip Boyle gets excited , cheering Gong on , but as Sora points out , Gong has to end his turn right there since he can ' t attack anymore . Gong vows to believe in Yuya and urges him to follow his Dueling ways as well . Yuya is seen again , declaring , " LADIES AND GENTLEMEN ! IT ' S SHOWTIME ! " His " Hippo Token s " dance above him on a rainbow as Yuya proudly presents the Entertainment Dueling inherited from Yusho Sakaki , and Grizzlepike ' s friends clap and cheer in appreciation , while Yuya politely bows . Back at the Duel , Grizzlepike slams his foot into the ground , incensed at Gong believing in others , since people betray one another , just like Gong ' s monster betrayed him . He declares his turn and draws " Shaman Battleguard " . Holding the card up , Grizzlepike Tributes his three monsters to Special Summon " Shaman Battleguard " , who appears cackling and dancing , terrifying the kids in the crowd . Sora is more interested by the 2000 ATK of the Level 10 monster , which probably means that it ' s got something special about it . He ' s proven right as Grizzlepike activates the effect of " Shaman Battleguard " , taking control of an opponent ' s monster . This time , he takes control of " Big Benkei " , and " Shaman Battleguard " sends out a shockwave that takes control of " Big Benkei " . The kids are horrified that " Big Benkei " was taken control of as well , and Grizzlepike yells that there is nothing worth believing in in the world , suggesting that Gong accept that as he takes this attack . " Big Benkei " attacks directly , much to everyone ' s horror , and Gong takes the blast full on , howling in agony as it pushes him , still standing , through the trees and onto a cliffside . He stops inches from the edge and drops to his knees as his LP falls to 500 , Nico commenting that that one must have hurt , 3500 damage all at once . Skip asks if Gong is okay , and Julia sympathetically admits that it hurts to watch this , Dipper observing that Gong only has 500 LP remaining . Kit snaps at Gong , asking if he ' s trying to embarrass Kit . Grizzlepike walks up laughing that Gong managed to save himself at the edge of a cliff . The next attack is game over . As Gong gets up , as Pike tells him that standing up is a waste of time , he ' ll take the attack of " Shaman Battleguard " and plunge into the ocean behind him . No matter how much Gong believes , his friend isn ' t coming . Gong yells that Yuya will come , he believes it , and Grizzlepike tells him to save that thought as he takes this attack , ordering the direct attack of " Shaman Battleguard " . Gong activates the effect of the " Superheavy Samurai Gigagloves " in his Graveyard . He can banish it to target the attacking monster , draw a card and reveal it . If it is a " Superheavy Samurai " monster , the attacking monster ' s ATK becomes 0 . Time seems to slow as Gong readies himself to draw , his friends gasp and he draws explosively , getting " Superheavy Samurai Soulbuster Gauntlet . " Flames envelop Gong ' s fist and he raises it , yelling that he believes in Yuya . He brings his hand down as the ATK of " Shaman Battleguard " falls to zero , yelling that Yuya will definitely come , and karate chops through the spike on the side of the skull - hand of " Shaman Battleguard " . The broken spike slices through Gong ' s sash as " Shaman Battleguard " leaps away . No matter what , Gong ' s spirit that believes in his friend shall never waver . The crowd cheer as Nico praises Gong ' s move in dodging his opponent ' s final attack by a hair ' s breadth with his back to the abyss . Grizzlepike scoffs , claiming that Gong just got lucky , and he warns Gong that as long as he controls " Big Benkei " , Gong can ' t attack " Shaman Battleguard " , which can only take control of a single monster , but should Gong happen to Summon one that is stronger that " Big Benkei " , Grizzlepike can swap " Big Benkei " out for it . So basically , Gong has no way to win . Gong looks down at his torn sash that this father gave him for this battle , but it isn ' t what he needs now . What he needs now is . . . Then he hears Yuya ' s voice calling his name , and Yuya stands proudly at the top of the bleachers , holding Gong ' s white sash . His friends all call his name , and Gong comments that Yuya is finally here . Yuya apologizes for the wait , and tosses Gong ' s sash to him . Gong catches the sash , and declares that he ' s gotten the sash from Yuya . He believed , and Yuya came , and this is now Gong ' s sash for victory . Gong declares his turn and draws " Superheavy Samurai Battleball " . He Summons " Battleball " , a Tuner monster , and Grizzlepike scoffs , pointing out that without any other monsters , the Tuner monster is just fodder . Gong replies that " Battleball " can use a Machine - Type monster on his opponent ' s field to Synchro Summon , much to Grizzlepike ' s shock , and Gong tunes the Level 2 " Battleball " with the Level 8 " Big Benkei " , chanting , " Raging deity , in unison with the soul of a thousand blades , come forth in a spiraling sandstorm ! Synchro Summon ! Now come before us ! Level 10 ! Superheavy Samurai Warlord Susanowo ! " Kit and Skip cheer at Gong ' s successful Synchro Summon , and next , Gong equips " Superheavy Samurai Soulbuster Gauntlet " from his hand to " Susanowo " , increasing its DEF by 400 , to 4200 . Grizzlepike realizes in shock that , as Gong confirms , just like " Big Benkei " , " Susanowo " can attack using its DEF . Gong declares his Battle Phase and attacks " Shaman Battleguard " with " Susanowo " . Ally and Tate realizes that since the ATK of " Shaman Battleguard " is currently zero , as Sora confirms , Gong will end it in one attack . Frederick gets a hefty bout of his shivers . Gong orders " Susanowo ' s " " Swinging Sword Slash " , cutting the " Battleguard " down and wiping out Grizzlepike ' s LP . Nico announces Gong as their first Junior Youth winner of the day , and Kit sighs in relief that Gong finally won after making him sweat like that . Gong walks over to Yuya , telling Yuya that he believed in him , and shaking his hand as Yuya replies that he believed that Gong would win . Skip , Zuzu and the kids run over , asking where Yuya was . Yuya apologizes , reassuring them that he ' ll do his best in the next Duel so that he doesn ' t fall behind Gong . Nico announces the participants for the next Duel , You Show Duel School ' s Yuya Sakaki versus Leo Institute of Dueling ' s Sylvio Sawatari . Yuya heads onto the field , declaring that he ' s off .
