Aichi and his friends have won the National Tournament and decide to go their own ways until a mysterious boy named Takuto Tatsunagi appears. He reveals that the Royal Paladins, Dark Paladins, and Kagero leaders have been captured, and the only way to free Cray is for the Vanguard fighters to use a new power- Limit Break. Because the Royal Paladins lose the ability to fight, Aichi's deck is changed to be a Gold Paladin deck. Aichi and his friends must now win the Vanguard VF Circuit if they are to learn more about the occurrences on Cray and free their old friends. (Source: ANN)






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.
