Card Fight!! Vanguard

Kids from all over town converge to play Vanguard, a card game that seems to be the biggest thing going around. Aichi Sendou is a shy boy with a rare card, the Blaster Blade, who just started playing this new card game.

After Aichi plays Blaster Blade, he and Kai recall their first meeting. Back then, after seeing a young Aichi beaten up, the young Kai cheered him up by giving him Blaster Blade.

Concerned for her brother, Aichi's Little sister, Emi, secretly follows Aichi to the Card Capital. There, Emi is astounded by all the people in the shop, including Aichi, Morikawa, and Izaki, playing Vanguard.

After taking a look at Aichi's deck, Shin decides to show him "something nice". Shin has Aichi battle Misaki Tokura, who, despite working at the card shop, has never actually participated in a Vanguard fight before.

Aichi goes to the card shop to buy a booster pack in the hopes of getting a Grade 3 card. When he arrives, he sees a grade-school kid, Kamui Katsuragi, convincingly defeating Izaki in a cardfight.

In the commercial center they lost they're way, but Aichi found the card shop called PSY. There, they try out the shop's special Vanguard Fight Stage.

Shin introduces the "Standing Fight Table" to enrich the experience of a Vanguard fight, with Morikawa and Kamui being the first to play on it.

The Card Capital Shop Tournament begins soon, but Aichi is hesitant to play in it, even after making a new deck. However, when he learns that Kai will be in the tournament, Aichi decides to enter as well.

The Card Capital Shop Tournament finally begins. In the first round, Aichi must play against Izaki while at the same time, Morikawa battles Misaki. Since this is his first time in a tournament, Aichi grows nervous.

Kamui and Kai advance to the second round of the tournament, along with Ninja Master M, an eccentric player who dresses and acts like a ninja. He meets Aichi, who deduces that he is actually his teacher Mark Whiting, but he denies that claim.

Aichi makes a comeback by calling more units from his deck to boost the power of The King of Knights, Alfred, forcing Ninja Master M to use most of his cards to guard against his attacks.

It's the semifinals: Kai plays against Misaki, and Aichi once again battles Kamui. Both Aichi and Kamui want to win for their own reasons; Aichi wants to fight Kai again while Kamui hopes to gain Emi's affection upon winning the tournament.

The semi-finals come to a conclusion and the final match in the shop tournament is underway! Aichi challenges Kamui, trying to get revenge for his previous loss.

Aichi heads out on a journey to other card shops, in order to find and fight other strong Vanguard fighters and gain experience after the Shop Tournament.

As Emi continues coming to the Card Capital Card Shop, the Manager convinces her to try the game out for herself.

The regional tournament begins. Team Q4 (Aichi, Kamui, Kai and Misaki) has to face Team Three Blacks in the first round.

Aichi has difficulty pushing for victory, and his opponent gets a Critical trigger on top, bringing him to five damage. Aichi desperately needs to block the next strike, but is unwilling to leave his hand empty.

The regional tournaments continue, with Team Q4 easily plowing through their second and third opponents.

Surprisingly enough, Nagisa steps into the fray as the first fighter of Team Handsome, resulting in Kamui being in a desperate situation as she declares that Kamui has to marry her if she wins.

Team Q4 has to win the next matches in order to advance through the regional tournament. Aichi becomes increasingly desperate, as his match will be the one to decide the fate of the team.

Aichi realizes that he cannot stay the same as before if he wishes to win. Using a combination of the skills of Barcgal and Future Knight, Llew, he Rides Blaster Blade from the deck, surprising Gouki.

The fight between Aichi and Gouki continues. Aichi blocks Gouki's attack, and counterattacks with Alfred, bringing Gouki to five damage.

Aichi, Kamui and Misaki visit Card Shop PSY after Suiko's invitation. They meet an aloof red-haired stranger, who is Suzugamori Ren, the winner of the previous national tournament!

To prepare for the national tournaments, Aichi and Misaki engage in a fight. However, memories of her tragic past surface in Misaki's mind, causing her to break down.
