Emi starts taking an interest in Vanguard because of Aichi. One day while visiting Card Capital, Shin gets Emi to participate in a Vanguard fight for the first time!

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.

Aichi challenges Kamui, trying to get revenge for his previous loss. Since their last fight, the gap in their skills has closed considerably. Aichi puts everything he's got out there in order to reach that fight with Kai he's aiming for.

It's already the semi-finals of the Shop Tournament and standing up against Aichi is none other than Kamui! As the fight begins Aichi and Kamui don't hold back one bit, going at each other with full force! With that invigorating tension, they battle on!

Aichi continues getting his hands dirty in a fight with the mysterious Ninja Master in the second round of the Shop Tournament. Using the skills of his "Nubatama" deck, the ninja backs Aichi into a corner!

With the first round over, the Shop Tournament is really starting to heat up! There's a fight that's drawing everyone's attention, between a middle schooler and an adult dressed as a ninja who is trying to defeat him!

Aichi is participating in the Shop Tournament held at Card Capital. The usual gang is there, plus a bunch of unusual folks... But Aichi's gaze is focused only on one place...

Aichi is trying to decide whether to enter Card Capital's upcoming Shop Tournament, but is worried that he isn't good enough to compete. He finds himself coming to the shop anyway, and there's only two spots left! Just then, Kai walks in, and submits his entry form. Knowing that he might get to fight Kai if he enters, Aichi leaps at the chance, but just before he enters, another person sneaks in their application at the same time! There's only one spot left in the tournament, so there's only one way to settle this: An on-the-spot fight! Aichi is full of motivation, but can he defeat an opponent who seems to have accounted for everything?

Shin gets a brand new "Standing Fight" table for his shop, and so to test it out, Morikawa and Kamui have a fight. Afterwards, Aichi and Kamui notice Kai walking about town, and decide to follow him to see where he lives now. Kai notices, and Kamui challenges him to a fight. Kai senses a strong opponent, and agrees to the challenge, but does Kamui really know what he's getting into?

Aichi, Morikawa, and Izaki go into the city to a card shop. Aichi is all excited about his first time in another card shop than Card Capital. It's then that Morikawa gets lost, and they can't find the shop. Right when they're about to give up, before Aichi's eyes there appears an extremely mysterious card shop...

One day, when Aichi pops his head into Card Capital, Morikawa is fighting a kid he's never seen before. The kid is so powerful, Morikawa can't even scratch him. His name is Kamui Katsuragi, and he's a famous grade-school fighter in the area.
