Cardfight!! Vanguard

Aichi Sendou, a timid youth who gets his precious card taken by his classmate, Katsumi Morikawa. Aichi goes after Morikawa, and heads towards a card shop called Card Capital.

Aichi Sendou challenges Toshiki Kai to a cardfight in order to get his card, Blaster Blade, back. As Kai teaches Aichi about the rules, he notices Aichi's smile during the fight.

A young cardfighter, Kamui Katsuragi, heads towards Card Capital in order to become the strongest cardfighter. Kai nominates Aichi, who happens to be at the shop, to fight Kamui.

Misaki Tokura, a shop assistant inexperienced with cardfighting, becomes interested in Vanguard upon seeing how Aichi Sendou evolves. With an invitation from Aichi, Misaki steps up to her first fight.

Aichi Sendou applies to join the CF Research Club that Katsumi Morikawa and the rest are in. However, CF Research Club faces the crisis of being abolished with the grades of Morikawa and the rest being far below acceptable.

Aichi and the rest encounter Leon Soryu, champion of the Asia Circuit, and Gouki Daimonji, runner-up, at the grand Cardshop "Voyage"that Kamui Katsuragi originally played at.

Kenji Mitsusada joins and forms a team at "Voyage" with the other members of Asia Circuit's top 3, and is set to participate in the shop battle. One day, Mitsusada visits Card Capital without notice.

The shop battle begins with Card Capital's representative, Team Q4, facing off against Voyage's representative, Team NwO. Gouki Daimonji and his sister Nagisa are the first members that Q4 needs to defeat.

The proud fighter, Toshiki Kai, and Emperor of the Card World, Kenji Mitsusada, face off in the third match of the shop battle. The two fighters with high potential are neck and neck in this climax fight where both of them use their trump cards.

Fourth match of the shop battle has Aichi Sendou facing off against Leon Soryu. Fighting an uphill battle against Leon's "Wind", Aichi experiences a different imagination for his fight.

Kamui Katsuragi and Gouki Daimonji battle in the deciding match. While trying to defeat Gouki, Kamui recalls what Gouki once said to him.

Minami Kawanami, a member of the mysterious group "Asteroid", appears at Card Capital. The "VF Glove" that they use appears to be dangerous item that allows the damage of cardfights to manifest.

Voyage gets taken over by Asteroid. Kamui challenges a member of the strongest team "AL4", Kyou Yahagi, in an attempt to reclaim the place where he used to belong.

The one who spoke to Aichi while his movements were sealed by the lethal combo of Kyou's "Dueling Dragon, ZANBAKU", was none other than the Blaster Blade from his imagination.

Asaka Narumi of Team AL4 appears at Card Capital looking for the place that Kai belongs. Foreseeing that, Miwa faces Asaka and the Asteroids in an attempt to keep them away from Kai.

Misaki and Asaka battle. Ren Suzugamori, the leader of the Asteroids, appears during their fight. Meanwhile, Kyou suggests to Aichi and Kamui that thay should go "Asteroid Hunting".

Aichi learns from Kyou that hearing the voices of cards is something known as "PSYqualia". And Misaki's fight against Ren, who's able to use that ability, is...

Kai recollects hanging out with Ren and Tetsu of Team AL4, and his reunion with Aichi, upon knowing that Ren paid a visit to Card Capital.

Tetsu appears before Aichi and friends while they are Asteroid hunting. The hidden power of PSYqualia is discovered when Tetsu challenges Aichi to a cardfight for his research on PSYqualia.

Kai and Miwa enter the Asteroid headquarters and defeat the members. Elsewhere, after the fight with Tetsu, the exhausted Aichi and Kamui encounters the leader of Asteroid, Ren.

Teams Q4 and AL4 gather at the Asteroid headquarters. Kai fights Ren in a decisive battle to protect Aichi. The battle begins between Kai, who denies the power of PSYqualia, and Ren, who is overflowing with that power.

Kai and Ren faces off in the destined match. While teams Q4 and AL4 watch on, Kai rides a new trump card. Who will come out on top in this serious fight?

The fight between the users of PSYqualia, Aichi and Ren, reaches its climax. Can Aichi overcome Ren, whose imaginations originate from a warped thirst, and sever the chains of these fights?

Aichi and friends return to their peaceful days after the battle against Asteroid. A few days later, Kai challenges Aichi to a fight at Card Capital.
