Cardfight!! Vanguard: Asia Circuit-hen

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 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.

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.

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.

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

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
