Cardfight!! Vanguard Asia Circuit

A few weeks have passed since Team Q4 won the national tournament. One day, Aichi goes to Card Capital and meets a young boy who wants Aichi to teach him how to play Vanguard. Aichi agrees and teaches the boy about Vanguard through playing a game, much like how Kai taught him. The boy, using a Gold Paladin deck, eventually drops the newbie facade. When he rides Great Silver Wolf, Garmore, he draws Aichi into a vision of the Royal Paladin's Blaster Blade, Shadow Paladin's Blaster Dark, and Kagero's Dragonic Overlord being captured by a mysterious force on the planet Cray. He then tells Aichi that a new power that can go past the boundaries must be attained in order to combat this force. After the vision, the boy disappears and Aichi discovers that his Royal Paladin deck has changed to a Gold Paladin deck. What's more is that everyone else's memories have been rewritten to think that Aichi has always used Gold Paladins, not even noticing the change.

Depressed about losing his Royal Paladin deck, Aichi meets Kai. He learns that not only has Kai's deck been changed to a Narukami deck, but also that Kai has no memory of using a Kagero deck or of Aichi using Royal Paladins. To find some answers, the two have a cardfight. As Aichi struggles to get comfortable with his new Gold Paladin deck, Kai slowly realizes that something is off. Getting his memory back, Kai nonetheless chooses to continue using his current deck, but Aichi is conflicted about using his. Kai tells Aichi that he is bound by his own limits by not wanting to use Gold Paladins and that he needs to break through them. To prove his point, Kai rides Dragonic Kaiser Vermillion, declares "Final Turn", and performs Limit Break, an ability that activates when a player has 4 or more damage. With Vermillion's Limit Break, Kai attacks all of Aichi's front-row units in one strike and wins as a result. After the battle, Aichi and Kai watch a commercial advertising the Vanguard Fight Circuit, a worldwide invitational tournament which is sponsored by Takuto Tatsunagi, the young boy that Aichi met before and the one responsible for the phenomena of changing their decks. To use the VF Circuit as a way to reach Takuto, Aichi and Kai go their separate paths. When Aichi goes to Card Capital, he is surprised to learn that Team Q4 has received an invitation to the VF Circuit.

After receiving the invitation to the VF Circuit, Aichi wants to enter with all of the original members of Team Q4 (minus Kai). He convinces Misaki to rejoin with no problem, but then Aichi learns that Kamui has joined Team Handsome. So, he goes to Card Shop Handsome to recruit him back. When Aichi tells him about the invitation, Kamui becomes torn between his own feelings of wanting to participate in the Circuit and his promise to Team Handsome to go with them to the upcoming national tournament. It is ultimately decided to settle things with a cardfight between Aichi and Kamui. If Aichi wins, then Kamui will return to Q4 and enter the VF Circuit. If Kamui wins, then he stays with Handsome. And so, Aichi and Kamui's cardfight ensues. As Aichi tries to get used to his Gold Paladin deck, Kamui puts on the pressure with his slightly-improved Nova Grappler deck, driving Aichi to 5 damage. But this allows Aichi to access the Limit Break of his vanguard Great Silver Wolf, Garmore and increase its power by 5000, thus surprising and defeating Kamui. Although Kamui is initially saddened by this loss and leaving Team Handsome, he is glad to be with Aichi again and have the chance to play in the VF Circuit.

With Team Q4 reunited, Aichi, Kamui, and Misaki go shopping in preparation for the VF Circuit. After they finish their shopping, they visit Card Shop PSY so that Aichi can talk to Suiko about the mystery behind the replacement of his Royal Paladin deck. Once there, they find out that the Ultra Rare girls will also be going overseas. Noticing the large amount of shopping bags that Team Q4 has, Rekka questions the team's motive for participating in the VF Circuit. When Misaki says that she's going because she was asked to, Rekka insults her for treating their ticket to the VF Circuit as a free vacation and having no intention to win. To prove her wrong, Misaki challenges Rekka to a cardfight. While using the new Angel Feather clan to use cards in her damage zone to her advantage, Rekka criticizes Misaki's deck for being good but still lacking. Rekka then shows Misaki what that missing attribute is when she rides Circular Saw, Kiriel and utilizes its Limit Break to defeat her. Through this loss, Team Q4 realizes that they must change their mentality and their decks if they want to have a chance to win the VF Circuit.

Q4 arrives in Singapore. While sight-seeing, they run into their friendly rivals, Team Caesar. Kenji and his friends take them to a local university, SIT (Singapore Institute of Technical Studies), where students learn about specific studies in Vanguard and where Kenji hopes to attend when he graduates from high school. They then meet three young boys, Christopher Lo, Ali Pajeel, and Lee Shenlon, who are students of the university despite being the same age as Kamui. The SIT boys get into a heated discussion about how they got an early start in attending SIT and how there's little to no hope for those who attend later than they have. After leaving the university, Aichi sees Takuto and follows him trying to get an answer. Kourin arrives and lets him know the only way to meet with Takuto is to win the VF Circuit. Before leaving, Kourin gives Aichi a card, Incandescent Lion, Blond Ezel. He returns to the hotel and reorganizes his deck with his friends and with cards that Shin purchased in Singapore. The next day, the VF Circuit begins. Q4 learns that Chris, Ali, and Lee are the members of a rival team, SIT Genius, in the VF Circuit, and the worldwide broadcast of the Circuit begins.

The Vanguard Fight Circuit begins with Aichi, Kamui, and Misaki playing their matches simultaneously! Their first opponents: the world-traveling ninjas, Team Shinobi!

Kamui has won his match, so now it's up to either Aichi, Misaki or both to best their ninja opponents, who are much more worldly than Team Q4. What effect will Aichi's new card have on the match?!

Team Q4 battles Team Divination in the 2nd round. All 3 members supposedly have psychic powers that allow them to see the future, and they each play with Oracle Think Tank decks, the same deck Misaki uses. The familiarity with the deck gives Team Q4 the advantage as they sweep Team Divination while exposing them as phony prophets. After the battle, Team Q4 runs into Team SIT Genius on the street. Kamui vows never to lose to fighters the same age as he is, and Misaki wonders how she can avoid facing off against an opponent with the power of Limit Break.

Team Q4's 3rd round match begins; their opponents are revealed to be against Chris, Ali, and Lee - Team SIT Genius. Lee Shenlon is shown having great pride, and he declares he is the only one who can defeat Chris. Meanwhile, Ali promises to defeat Kamui and steal Emi from his heart forever. Ali seems to have the advantage as Kamui is given a quick 5 damage to Ali's 3. Misaki gives Lee 3 damage and then attacks the rearguard, fearing Lee might have the power of Limit Break. That move is made void though as Lee plays a card that will give him one additional damage for a full turn, thus giving him the power to gain Limit Break.

Kamui vs. Ali and Misaki vs. Lee Shenlon finish their matches. The results will be a 1-1 draw. As the scene shifts to Aichi vs. Chris, Takuto Tatsunagi calls out to both of them with his spirit on Cray. Aichi's Psyqualia is returned, but Chris also gains the power of Psyqualia and slowly begins to go mad. Takuto states this is the only time he can interfere in a match, and in order for Aichi to gain any additional knowledge about Cray and the Royal Paladins, he will have to win the tournament.

The battle between Aichi and Chris continues, but this time both amp it up by using Psyqualia. Chris declares he will defeat Aichi with a triple slash from his School Hunter, Leo-pald, but the experience against Ren's Psyqualia could give Aichi the advantage in this match.

Q4 returns home to rest and recover for the next leg of the Circuit. Aichi learns that Kai hasn't appeared at Card Capital and hasn't been seen in the city since they left. As Aichi wonders about his missing friend, the scene shifts and reveals Kai is traveling the world getting stronger. Currently, he is in a snowy mountain region where he battles a rumored abominable snowman. It is soon revealed that the snowman is actually Kyou Yahagi in disguise, still aiming to get his revenge on Kai. Kyou has gained new cards, one of them being Demonic Lord, Dudley Emperor which has the power to Limit Break. Can Kai manage to withstand 5 attacks that could result in up to 7 damage in 1 turn?

While Team Q4 trains at Card Shop Handsome to get ready for the next round of the VF Circuit, the group is informed that Tetsu has arrived to Card Capital, assuming that he is causing trouble. However, their assumptions are disproven when they return and see Tetsu helping out Emi and the other kids at the shop. Kamui asks Tetsu what his real intention for coming is, to which Tetsu answers by telling Q4 how weak the team is due to losing at the VF Circuit's Singapore Stage. Enraged, Kamui challenges Tetsu to prove him wrong. Tetsu accepts the challenge, and the two start their cardfight. With support from the latest expansion set, Tetsu uses new Dark Irregulars to soulcharge, and then he utilizes the Limit Break of Dark Lord of Abyss to overwhelm and defeat Kamui once again. Tetsu leaves, warning Q4 of stronger teams awaiting them in the VF Circuit. Although Kamui thinks that Tetsu was being mean, Emi and the others believe that Tetsu was really trying to tell Q4 something underneath his harsh words...

The Seoul Stage of the VF Circuit begins with Team Q4 coming across Team Movie Stars, the local favorite favored to win the Seoul Stage. The teams head into the cardfight area where they learn special rules will be applied in this stage. Team Q4 faces off with Team Seven Seas, who are all pirates who use Granblue decks like Team Handsome. Aichi's special rule is to have a drive check for rear-guards, Misaki's rule is all turns must be completed within 30 seconds, and Kamui's rule is you can't see what you attack. Aichi trails 4 damage to 2 when he summons Incandescent Lion, Blond Ezel and places 2 grade 3 units in the rear-guard zone. This means he gets a minimum of 6 drive checks. His opponent guards twice, but thanks to 2 stand triggers, Aichi manages to pile up the damage and wins 6-4. Misaki memorizes her opponent's hand and makes it where he can't guard with a timely bind allowing her to win 6-2. Kamui keeps missing his opponent, but through the process of elimination, he destroys all the rear-guards and eventually gets to his opponent's vanguard. Kamui manages to stand three of his rear-guards to win 6-2. They go to watch Team Movie Stars match only to find out it has finished. Team Movie Stars has been defeated by Team New AL4 consisting of Ren, Asaka, and Kai. The second round is set with Team New AL4 battling Team Q4.

Team Q4 confronts Kai to learn why he joined the VF Circuit, and the match between Team Q4 and Team New AL4 begins. Ren battles Aichi, Kamui must try to defeat Kai, whom he has never defeated before, and the tiebreaker between Asaka and Misaki all begin. The special rule is each player starts with 2 damage and they play until 8 damage has been made, meaning that a player can activate Counterblast skills immediately and use Limit Break more quickly. Kai overwhelms Kamui with 2 Limit Breaks from Dragonic Kaiser Vermillion and defeats him 8-6. Misaki holds a slim lead on Asaka 6-5. Ren and Aichi are contacted by Takuto who gives back to Ren the power of Psyqualia and asks them what they see to lead them to victory.

The matches between Misaki vs. Asaka and Aichi vs. Ren continue. Asaka rides a new card, Silver Thorn Dragon Tamer, Luquier, and uses its Limit Break to superior call 3 units from her soul. She launches powerful attacks that Misaki cannot guard against and ultimately wins. Asaka walks away victorious while being disappointed in Misaki's performance. Meanwhile, Ren rides Spectral Duke Dragon and later attacks Aichi's Blond Ezel with it. Aichi guards against it, but then Ren utilizes the Limit Break of Spectral Duke Dragon to have it stand up and attack again. Aichi is unable to block this attack, giving Ren the victory, just as he predicted with Psyqualia. This 3-0 sweep means that Team New AL4 moves on to the next round, with Team Q4 learning how much Team New AL4 has changed.

Team Q4 watches the final round of the Seoul Stage, which pits Team New AL4 against Team Caesar. The special rule for all of the fights in this round is that only 3 rear-guard units are allowed to stand at the beginning of each turn, thus limiting overall attacking power. The matchups are Kai vs. Gai, Asaka vs. Yuri, and Ren vs. Kenji, with Ren deciding to borrow Tetsu's Dark Irregulars deck for his match. Ren and Kenji exhibit world-class play as Ren builds up his soul to power up both his vanguard Blade Wing Reijy and rear-guard units. Ren tries to attack Kenji's rear-guards to hinder his upcoming strategy, but Kenji successfully protects them. Kenji then declares "Final Turn", moves his Dimensional Robo rear-guards to the soul, and superior crossrides his new key card, Ultimate Dimensional Robo, Great Daiyusha. This tactic dubbed as the "Dictator Super Combination" and Great Daiyusha's Limit Break raise its power to unprecedented heights, and along with getting a draw trigger, Kenji finally fulfills his goal of defeating Ren. However, the celebration is cut short when he learns that Yuri and Gai have lost their matches, meaning that Team New AL4 wins the Seoul Stage by a score of 2-1. Before New AL4 is transported to the next round, Kai informally tells Aichi and Q4 how they must get stronger if they hope to ever cross paths with him again.

After returning home from Seoul, Team Q4 runs some errands to help Aichi relax after the team's loss. Then, in front of Card Shop PSY, they meet a young blonde-haired and mysterious man named Leon Souryu, who is able to feel the "wind". The Ultra Rare trio returns, and they discover that their supposedly-closed shop is unlocked. The entire group enters, and they are surprised to find that the legendary cardfighter Daigo is there. It was believed that Daigo had gone missing for months, to which Daigo explains in a private conversation with Ultra Rare that he had been randomly teleporting from place to place. Suiko believes it is because of Daigo's deck, which is composed of Royal Paladins, one of the clans that were removed from the world, and therefore considered legendary by everyone except Aichi. Afterwards, Daigo offers up a challenge to anyone willing to cardfight with him. Before Aichi can accept, Leon steps up to be Daigo's opponent. And so, Team Q4 and Ultra Rare observe the fight between Daigo using Royal Paladins and Leon, whose deck is composed of another legendary clan: Aqua Force. Although Aichi is familiar with Royal Paladins, Daigo uses units that even he has never seen before, including White Dragon Knight, Pendragon. Leon rides Navalgazer Dragon and uses its seemingly-simple Limit Break to increase its attack power by 3000, which Daigo guards against. Daigo then utilizes the Limit Break of Pendragon to superior ride Soul Saver Dragon, using its skill to power up his rear-guards, but Leon defends and makes it to his next turn, which he declares as the "Final Turn". After activating the Limit Break of Navalgazer again, he attacks. Daigo tries to block with all of the cards in his hand, but Leon gets a heal trigger, giving the power boost to Navalgazer and breaking through Daigo's defenses. Although Daigo manages to survive thanks to his own heal trigger, Leon then reveals the other effect of Navalgazer's Limit Break; since it successfully attacked the

Team Q4 and friends travel to a distant southern deserted island with an invitation from the VF Circuit, but when they arrive, they learn that Team New AL4 has also been invited. While Team Q4 is fixated on training to get stronger, everyone else is looking for some rest and relaxation. Later that night, after dinner, Ren gathers everyone together and gets them to agree to be in a test of courage, with some having the job of scaring people and the others being put to the test. Shenanigans ensue such as the supposedly-stoic pair of Misaki and Asaka easily getting scared to the point of fainting and Kamui failing to scare Tetsu for being paired with Emi. Aichi and Kai are teamed together to go through the course, but instead of doing so, Kai takes Aichi off on his own and gives him some words of encouragement, which are topped off by a fireworks display.

Q4 and New AL4 continue their vacation on the southern island, with each member of Q4 having their own story to tell. Kamui gets depressed when he loses to Tetsu again, and his friends Reiji and Eiji cheer him up. The three then undergo a rigorous training regimine, which gives Kamui inspiration to make a new deck revolving around the Raizer series. But once again, in spite of this new deck, Kamui is defeated by Tetsu. After getting coaxed into playing beach volleyball with Ren and Asaka, Misaki cardfights with Ren, with both of them borrowing others' decks. Ren reveals the reason as to why he fights with other people's decks is to not only try and find a more suitable clan for him to use, but to also gain a better understanding of his own deck. With that in mind, Misaki constructs a new Witch-themed Oracle Think Tank deck and defeats Ren, this time borrowing Emi's Bermuda Triangle deck. Aichi turns his focus toward developing a new deck. He finally accepts the gift of Psyqualia and uses it to construct a new deck while also fully embracing the Gold Paladin clan. All the while, Izaki tries to fish but a suntanned Morikawa's swimming gets in the way, and Miwa cardfights (and repeatedly loses to) Kai. Team Q4 and friends take a flight home while New AL4 stays on the island.

Q4 returns to Japan with new strategies for winning being devised. Aichi and Kamui test them in the final round of a tournament held at Card Shop Handsome. Unbeknownst to them, Kenji Mitsusada arrives, looking for Aichi. Gouki tells him that Aichi is currently in a cardfight with Kamui. Feeling anxious and being short on time, Kenji decides to leave until Gouki challenges him. It's the first-ever match between the two. Although Gouki gets a bad starting hand with no grade 2 or 3 units, he manages to smoothly superior ride with cards he sent to the drop zone, including his new ace card, Ice Prison Necromancer, Cocytus. Kenji is impressed by Gouki's determination to overcome the odds stacked against him, to which Gouki expresses his disappointment in Kenji the "Emperor" for saying such a thing to begin with. Remembering the feeling of never giving up, Kenji continues to play at his best, crossriding Ultimate Dimensional Robo, Great Daiyusha and winning the match. After the battle, Kenji reveals his reason for coming: to tell Aichi that he is leaving to attend the SIT university and won't have the chance to participate in tournaments again until he graduates. Kenji was at first wavering on whether he could survive on his own and wanted Aichi to give him words of encouragement. But he regained his confidence after fighting Gouki, who gives Kenji his bandana as a farewell gift. Then, all of his friends go with Kenji, wearing Gouki's bandana, to the airport and wish him well in his upcoming journeys.

Team Q4 and friends head to the Hong Kong Stage of the VF Circuit, hoping to advance to meet with Takuto. While in front of the stadium, before the fights start, they have a short run-in with three males, one big, one normal-sized, and one small. Shin vaguely remembers seeing them before, and it is then that two identical girls appear. They tell him off by saying how that group is actually a powerful team before taking their leave. The Hong Kong Stage officially begins. The unique attribute of this stage is that each cardfight will be 2-on-2 tag-battle style; the first team to deal 9 points of damage instead of the usual 6 to the opposing team is the victor. However, Kamui cannot comprehend the numerous difficult rules, leaving Aichi and Misaki to pair up and take on Team Lao (the group of three men who they met earlier) in the first round. Throughout the fight, the special rules are exhibited and explained: the fighters must only attack the player standing in front of them, they are forbidden to consult their partners and show the cards in their hands to one another, but they are allowed to call guardians from their hands to block for their partners and share damage for Counterblast uses. Team Lao's Terence and Felix both use Tachikaze decks; Terence's Raptor units deliver major damage to Aichi early on in the fight. Using her new Witch deck, Misaki compensates for Aichi by riding Scarlet Witch, CoCo and using various skills to draw more cards, empty her vanguard's soul, and subsequently gain benefits from it. On the sidelines, Shin finally recalls that the members of Team Lao are actually three brothers who therefore have great teamwork with each other. Can Aichi and Misaki overcome the Lao brothers' team synergy and win?

The tag fight between Q4's Aichi and Misaki versus Lao's Terence and Felix continues. After Misaki's attack on Felix, he strikes back with Tyrant, Deathrex to put Team Lao in the lead. Then, wanting to make up for Misaki, Aichi rides a new ace card, White Hare in the Moon's Shadow, Pellinore. With its Limit Break, getting two drive triggers, and multiple superior calls from his deck, Aichi tries to finish the game with powered-up attacks. However, Terence manages to survive with support from Felix's tag guard. On Terence's turn, he also activates Limit Break, retiring his own units to increase the attack power of Military Dragon, Raptor Colonel while also superior calling more units from his deck. Aichi defends with all of the cards in his hand, and Misaki uses the extra cards drawn from her previous turn to tag guard with him. She anticipates Terence getting a drive trigger, which he does but her tag guards nonetheless successfully block his attacks. It is then that Aichi discovers what roles he and Misaki have during tag fights. With little cards left on Team Lao's side, Misaki wins the match on the following turn, thus making Team Q4 the victor. Afterwards, the Lao brothers praise Aichi and Misaki for their victory and newfound teamwork. Now, Team Q4 is one step closer to winning the Hong Kong Stage and having the chance to meet Takuto...

Q4 makes it to the semifinals of the Hong Kong Stage with Aichi and Misaki doing all of the cardfighting. After diligently studying the tag fight rules, Kamui offers to participate in the next fight. So, it is decided that Kamui and Misaki will pair up for their fight against Team Battle Weeds, a group of three kids who greatly admire the tenacity of weeds. True to their namesake, the members of Battle Weeds use Neo Nectar decks. Withstanding the Limit Break of Battle Weeds' ace card, White Lily Musketeer, Cecilia, Kamui proceeds to ride his new key card, Perfect Raizer. Its skill increases its power to exponential heights, and managing to pull a critical trigger, Kamui wins the match for Q4, thus advancing the team to the finals. However, Q4's next opponent is Team Dreadnought, with its members consisting of the two previously-encountered twin sisters, Jillian and Sharlene, and their leader, Leon Souryu.

Q4's Aichi and Kamui face off against Leon and Sharlene of Dreadnought in the finals of the Hong Kong Stage. Remembering Leon's fight with Daigo, Aichi and Kamui do their best to minimize the damage taken from Dreadnought's multi-attacking Aqua Force units. Although Aichi deals damage to Leon, he is unaffected by his attacks. Then, Aichi asks Leon what he means whenever he refers to the "wind". It is then revealed that Leon's "wind" is actually the power of Psyqualia. In a Psyqualia-induced vision, Leon tells Aichi a tale from long ago about a conflict between the many clans on the planet Cray. This war was eventually resolved by the appearance of the dominating Aqua Force armada. In the human world, the Souryu family had control over the Aqua Force which was used to hold power over the seven seas. However, for unknown reasons, the Aqua Force clan disappeared, and so did the Souryu family's power. The last remaining Souryu members foretold a prophecy of a child who would be "embraced by the wind" and restore the family name and the Aqua Force clan to their former glory; Leon believes that child is himself. In a flash, Aichi is shown a vision of two Blue Storm Dragon, Maelstroms, which Leon claims to be his "whirlwind" image of victory. Back to the tag fight, Leon rides one Maelstrom and activates its Limit Break. But Aichi uses a perfect guard to block its attack and safely makes it to his next turn. Does Aichi have the same kind of resolve that Leon has, willing to use Psyqualia to win?

Aichi uses Psyqualia to gain a winning image. Although things seem to go just as he envisioned, his attacks are foiled by Leon's perfect defense and Sharlene's tag guard. On the next turn, Sharlene again uses the Limit Break of Navalgazer Dragon and forces both Kamui and Aichi to use a lot of their cards to defend against its attack. Then, Kamui says that his turn will be the last as he rides another Perfect Raizer, bringing its power up to full potential. However, the usually-mellow Sharlene easily blocks Kamui's attacks and grows angry with his indirect "Final Turn" declaration. On Leon's turn, he follows his "wind" and calls another Blue Storm Dragon, Maelstrom as a rear-guard, now having two Maelstroms as Aichi had seen through Psyqualia. Leon attacks him with his vanguard Maelstrom powered up via its Limit Break, and Kamui tries to tag guard for Aichi. However, Leon's drive check reveals a stand trigger, giving his vanguard Maelstrom enough power to penetrate Q4's defenses and win the match for Dreadnought. Shortly afterwards, the two teams argue over the value of losing. Leon asks Aichi about what is the path he takes, and Aichi is reminded to make his own path. Leon bids farewell to him and says that they will battle each other again someday. Privately, Jillian asks Leon why he would console his opponents like that, to which he answers by saying it was the "wind" that told him to do so. He and Sharlene take an interest in Aichi's gentle "wind", which Leon sees as potentially becoming a great "windstorm" eventually. After Team Dreadnought is transported away, Shin informs Team Q4 about the next and last stage of the VF Circuit; it will be in their home country, Japan.

Aichi is feeling desperate by the fact that he and Q4 must win the Japan Stage of the VF Circuit. To better prepare the team, Shin recommends for Aichi, Kamui, and Misaki to battle against other stronger, non-Q4-affiliated cardfighters. Aichi takes a look at his Blond Ezel card and is reminded about Kourin, the person who gave it to him. So, Q4 goes to Card Shop PSY and requests for the Ultra Rare girls to cardfight with them for training purposes. They accept, and thus the battles ensue. The first match-up is between Aichi and Kourin, who now uses an Angel Feather deck. Aichi gains the upper hand when he superior rides Pellinore, but Kourin uses her Angel Feathers' skills to swap cards from her damage zone and then calling them. As the fight continues, Kourin antagonistically puts down Aichi by telling him to give up and how he's reached his limits. He proves her wrong and shows his determination when he rides Blond Ezel and activates its Limit Break to defeat her. Despite her harsh words, Kourin is actually glad that Aichi won. Then, the second match-up starts with Kamui against Suiko, who also uses an Angel Feather deck. Although Kamui takes some precaution by not dealing 4 damage to Suiko for fear of Limit Break, she nonetheless plays a card named Doctroid Micros, whose skill is used to purposely give herself 4 damage. Not only can she now activate the Limit Break of her key card, Chief Nurse, Shamsiel, but she also powers up all of her front-row units as well. How will Kamui deal with Suiko's Limit Break?

Kamui and Suiko's cardfight continues. Suiko uses Shamsiel's Limit Break and the Angel Feather stategy of switching cards from her hand with ones from the damage zone, thereby increasing her units' attack strength and acquiring the cards she wants. She also tells Kamui that power alone is not enough to win. Despite her words, Kamui manages to win through the sheer force of Perfect Raizer. Then, the rematch between Misaki and Rekka begins. Although Misaki gets the first turn, Rekka gets a grade 3 in play first by superior riding her new ace card, Crimson Impact, Metatron. With its Limit Break, Rekka superior calls more Angel Feathers from her damage zone and pressures Misaki to use a lot of her cards to block against her attacks. The two then have a conversation about how it was Rekka who motivated Misaki to change her deck. Misaki further elaborates that she was hesitant on changing her deck because she thought it would also mean changing the memories associated with her first deck. However, Misaki eventually realized that even if she did change her deck, it would not mean losing what was most important to her. Back to the game, Misaki takes a chance by riding another Scarlet Witch, CoCo, sacrificing attack power for the opportunity of drawing the card she needs to win. Her gamble pays off when she draws and calls a second Silent Tom. With 2 Toms, Misaki renders Rekka unable to guard with any grade 0 units against their attacks and emerges victorious. Afterwards, Team Q4 thanks Ultra Rare for the matches. But before Q4 can leave, three mysterious lights shine from the shop's holographic card displays. These lights make their way to Q4 and are revealed to be three new cards, one for each member. Suiko claims that the cards have chosen Q4 to be their owners. With newfound experience and cards, Q4 is now pumped and ready to win the Japan Stage.

The Japan Stage of the VF Circuit is drawing near, and many teams, including the victors of the previous stages, will appear there. As Team Dreadnought's plane lands in Japan, it is directed to and locked in a hangar with a jungle environment inside. It is really a trap set by Kyou Yahagi and his Team Avengers (all dressed as bugs), who plan to take Dreadnought's spot in the VF Circuit. Although Jillian and Sharlene handily take care of Kyou's teammates, he nonetheless challenges Leon to a cardfight. Now using a Megacolony deck after witnessing the strength of insects from his experience in the jungle, Kyou prevents some of Leon's units from standing and retires others. Thus, he seals the Aqua Force strategy of launching multiple attacks and Blue Storm Dragon, Maelstrom's Limit Break. In spite of Kyou's own Limit Break from his new ace card, Martial Arts Mutant, Master Beetle, Leon overcomes the obstacles against him when he calls more units to replace his rested ones and utilizes the max potential of his Aqua Force clan. Kyou's overconfidence gets the better of him when he leaves himself with little cards to guard against all of Leon's attacks, ultimately leading to his downfall and Leon's victory. After Kyou vows to get revenge on Leon, he and the rest of Team Avengers escape. The scene ends with Kyou and his team aiming to get stronger in outer space (in reality, they are in a public planetarium).

It's time for the last leg of the VF Circuit, the Japan Stage. Taking place in an amusement park, many familiar teams have gathered. The aspect for this stage is that each team member will individually fight others in three separate stadiums. Each victory that a cardfighter gets will earn his/her team 1 point; the team with the most points by the end is the winner of the entire Japan Stage and will go on to face the previous stages' winners at the Final Stage. What's more is that "special reserve" cardfighters like Team Unknown (composed of the masked trio of King Z, Queen Y, and Joker X) will participate and act as obstacles for all of the teams. With the rules fully explained, Aichi and Q4 resolve themselves to win the Japan Stage. And so, the fights begin. Misaki and Kamui win their respective matches. On the other hand, Aichi is in a close fight in a rematch with Team Jurassic Army's Gunji Ryudo. Against the threatening Limit Break of Ryudo's new ace card, Destruction Dragon, Dark Rex, Aichi successfully defends himself, using a lot of his cards in the process. Despite the odds, Aichi stays determined and utilizes the Limit Break of his Blond Ezel twice, superior calling more units from his deck and gaining power from them, which forces Ryudo to not guard against Ezel's attack. As a result, Aichi is victorious. After saluting him on his win, Ryudo warns Aichi of what's to come in the Japan Stage. Behind the scenes, Joker X is confronted by Kyou and Team Avengers, who plot to take Team Unknown's masks and assume their roles. However, Kyou is defeated by Joker X, who reveals his true identity to Kyou and shocks him. Soon after, Kamui awaits his next opponent, who turns out to be none other than Nagisa, clad in a bridal gown and eager to marry him right now.

After Nagisa appears in a horse-ridden carriage led by Team Handsome, she greatly exaggerates about being married to Kamui, which causes the audience to misunderstand the situation and embarrasses him in the process. Nonetheless, the two kids begin their cardfight, which is being treated as a wedding ceremony by Team Handsome. Nagisa's Death Army units battle Kamui's Beast Deity units in this Nova Grappler mirror match (with the latter forced to wear a groom's tuxedo). After protecting himself from the Limit Break of Nagisa's new ace, Infinite Corrosion Form, Death Army Cosmo Lord, Kamui crossrides his new key card which he received after Q4's time at Card Shop PSY: Ultra Beast Deity, Illuminal Dragon. With multi-pronged attacks, Kamui defeats Nagisa, who decides to leave him alone (for now, at least). Elsewhere, Aichi and Misaki win more matches for Q4. Shortly after, Q4's next opponent, Team Unknown, approaches each member. It will be Aichi vs. King Z, Misaki vs. Queen Y, and Kamui vs. Joker X.

It's Team Q4 against Team Unknown in the last round of the Japan Stage. Aichi's opponent, King Z, is revealed to be Jun Mutsuki, the King of Underground Fights, although Aichi does not immediately recognize him. Meanwhile, Misaki battles Queen Y and sees through her disguise. Queen Y is actually Yuri Usui from the defunct Team Caesar, and Yuri now uses the deck she originally had before joining Caesar: Oracle Think Tank. As for Kamui, he has not realized who Joker X is. As they battle, Joker X's voice and style of play with Dark Irregulars slowly remind Kamui of a certain someone. Aichi and Jun conduct their cardfight. Jun's "dark hero" Dimension Police units decrease the power of Aichi's vanguard. Because of this, he is forced to either take damage or use a lot of shields to guard. Even though Aichi loses Blond Ezel, he remembers his reasons for fighting and stays resolved. Using Psyqualia to gain an image of victory, Aichi superior rides Pellinore for a comeback. Afterwards, Jun leaves and has a short reunion with Kai. Now, Aichi awaits the results of Misaki's and Kamui's fights.

Yuri's Battle Sisters deal major damage to Misaki, giving her the lead 1-5. Misaki strikes back by riding her new ace card, Goddess of the Sun, Amaterasu. Yuri tries to guard her attack, putting Misaki in the same situation as the last time they fought each other. Misaki decides to take a chance, which pays off when she drive checks a critical and heal trigger, and evens out the damage 4-4. Thanks to Amaterasu and its Limit Break, Misaki ultimately wins. Meanwhile, Kamui continues his battle with Joker X, who rides No Life King, Death Anchor. Kamui defends himself against its terrifying skill with a lot of his cards. On the following turn, Kamui crossrides Illuminal Dragon and activates its Limit Break to stand his remaining units, thus forcing X to not guard against his attack. Kamui defeats Joker X without ever learning his true identity. Winning every match they had, Q4 is crowned the victor of the Japan Stage. After the awards ceremony, Q4 is led to a room where Takuto Tatsunagi explains everything. Expanding on what he previously said to Aichi, a mysterious force has invaded the planet Cray and captured the leaders (Blaster Blade, Blaster Dark, and Dragonic Overlord) of the united clans. The abduction of those three affected the human world by wiping their respective clans from existence. Nevertheless, through the VF Circuit, Takuto has gathered the winners (SIT Genius, New AL4, Dreadnought, and now Q4) of each stage to become the new vanguards for the clans of Cray and lead them in the battle against the mysterious enemy. Takuto transports everyone to a unique dimension that leads to Cray, where they all advance to the "True Final Stage". However, Team Dreadnought stands in their way, with Leon saying that he is the only one needed.

As Team Dreadnought stops everyone from moving forward, Leon reveals that his true purpose for entering the VF Circuit was to thwart Takuto's plan of freeing Cray from the enigmatic enemy. Leon also says he was the one who let the Royal Paladin, Shadow Paladin, and Kagero clans be sealed away by the enemy. His reasons for doing so are to set the Aqua Force clan free (which was also captured by the same foe), restore the Souryu family to its former glory, and then rule the world. Leon's Psyqualia is amplified by the dark powers of the enemy and blows everyone away. Later, after being knocked unconscious, Q4 awakens and speaks with an injured Takuto, who gives more revelations. He discloses the name of the mysterious enemy: Void, an evil power of emptiness that is currently encompassing the majority of Cray and will make its way to Earth if not stopped. Takuto also states that he manipulated everyone's memories to make them forget about the past relating to the 3 sealed clans in order to introduce the new clans, Gold Paladin and Narukami, for Aichi, Kai, and Ren to later use and get stronger for this upcoming battle to free Cray. After Takuto restores everyone's rightful memories, Q4 leaves him to find and confront Leon, who is currently allowing himself to be engulfed by Void's power. Resolute on saving Blaster Blade after remembering all that the card has done for him, Aichi receives a card that contains Blaster Blade's spirit, which aids the group in their search for Leon. Then, Q4 runs into Team SIT Genius' leader Chris attacking his comrades Lee and Ali. Falling under the negative influence of Psyqualia which is magnified by Void, Chris' obsession with being "number one" makes him go mad with power and prevents Q4 from going any further. To save Chris from what he once had undergone, Aichi engages him in a cardfight.

Aichi once again battles Chris, who uses Psyqualia to foresee his victory. Similar to their last match, Chris predicts that he will win when his new ace card Battler of the Twin Brush, Polaris strikes Aichi's Blond Ezel three times in one turn. While Chris' Psyqualia prophecies initially seem to be going the way he said they would, Aichi knows that Psyqualia is not 100% accurate nor is it just a dark power. On the turn Chris declares his victory, Aichi blocks the last two attacks from Polaris, therefore throwing off his winning Psyqualia image. Then, Aichi crossrides his new key card gained from his experience at Card Shop PSY: Blazing Lion, Platina Ezel. With its Ultimate Break, Aichi increases the power of all his rear-guards, thus overwhelming and defeating Chris. Now knowing what Psyqualia really is, Chris learns the error of his ways and is forgiven by his friends Lee and Ali. However, due to the law of the unique dimension they're in, Chris' loss forces Team SIT Genius to be transported back to Earth. Elsewhere, Team New AL4 confronts Team Dreadnought, and Kai is about to fight Leon.

While Jillian and Sharlene take on Ren and Asaka in a tag fight, Kai begins his battle with Leon. As the two fighters clash, Leon reveals his past. As it turns out, the legend of a child who would call forth the "wind" and lead the second coming for both the Souryu family and Aqua Force clan was just a fairy tale made up by the Souryu chief only meant to provide (false) hope to the young Leon, Jillian, and Sharlene. Eventually, the Souryu and Aqua Force would be forgotten and die out. Desperate to find power to save both, Leon met Void, who offered him Psyqualia. He accepted the power, and thus Leon became that prophesied Souryu child, turning that fairy tale into a reality. Back to the cardfight, Kai, who is furious at Leon's selfish actions of betraying the 3 clans, rides Dragonic Kaiser Vermillion and announces that he will defeat him.

Kai and Leon continue their cardfight with each side using their respective vanguards' Limit Break abilities. After he insults Leon by calling him a pawn to Void, Kai crossrides his new trump card: Dragonic Kaiser Vermillion "THE BLOOD". He activates its Ultimate Break to give it extra critical value and power, forcing Leon to use his few remaining cards to defend. Kai manages to deal 2 more points of damage, presumably ensuring his victory, but Leon gets a heal trigger to stay in the game. On the following turn, Leon also crossrides his new ace card: Blue Storm Supreme Dragon, Glory Maelstrom. Its Ultimate Break also makes Kai use the last of his cards to hopefully block its attack. However, Leon drive checks a critical trigger, thus plowing through Kai's guardians and winning the match. After Glory Maelstrom's attack, the dust settles and reveals Leon standing over the fallen Kai. Just arriving to the scene, Aichi runs towards Kai and picks him up. Weakened, Kai apologizes to Aichi for not being there with him throughout the entire journey and then tells him to continue down his path for both of their sakes. Team New AL4 is transported back to Earth due to Kai's loss, so now it's up to Aichi to defeat Leon.

The final battle between Aichi and Leon begins, with the latter predicting via Psyqualia that he will win when his Glory Maelstrom attacks Aichi's Blond Ezel. Signs show of the nothingness that is Void slowly destroying the dimension and creeping its way to Aichi. The darkness eventually affects Aichi as he falls unconscious and loses the will to fight. However, he remembers his loved ones and then hears a familiar voice, both of which help Aichi to stand up and continue the battle. He activates the Limit Break of Blond Ezel to superior call an astral form of his original avatar card: Blaster Blade Spirit. But even with that, Leon withstands Aichi's attacks and then crossrides Glory Maelstrom...

The fight between Aichi and Leon reaches its climax. After Leon uses the Ultimate Break of Glory Maelstrom to increase its power and prevent Aichi from guarding with grade 1 or higher units, Aichi attempts to guard with two grade 0 units. However, Leon drive checks a heal trigger, which gives Glory Maelstrom enough power to penetrate Aichi's defense. Aichi survives the attack thanks to his own heal trigger. Leon slowly grows weakened after absorbing Void's power as Aichi crossrides Platina Ezel and activates its Ultimate Break to overpower and finally defeat Leon. Void leaves Leon's body, and Takuto opens the path to the planet Cray, declaring that Aichi's Gold Paladin clan is the rightful leader of Cray. Aichi holds up his deck, and with a reformed Leon's help, the Gold Paladins and Aqua Force units dispel Void's darkness from Cray and free the sealed Royal Paladin, Shadow Paladin, and Kagero clans. Aichi then faints and has a vision of Blaster Blade and the other Royal Paladins appearing before him. Takuto telepathically informs him that he is now able to use Royal Paladins again. While Aichi is glad to hear that, he does not want to part with Gold Paladins after fighting alongside them for so long. The Royal Paladins fade away, as Blaster Blade tells Aichi that they will forever be with him. Everyone is then transported back to Earth. The next day, the finale of the VF Circuit takes place, and Team Q4 is crowned the winning team of the Circuit. Afterwards, Aichi and his friends return to their daily lives, with Aichi deciding to continue using Gold Paladins, now including a Gold Paladin version of his avatar card, Blaster Blade.
