The small group of Cardfighters who remember Aichi need one more member before they begin their search for him. Will Kamui be the one? Even though he should be satisfied in this "new world," he feels like something is missing. Naoki takes Kamui on to get him to remember, but Kamui just can't seem to recall the fighter he once admired...

Kai continues his quest to find more "mates" who will remember Aichi's existence. Next up is Miwa, who's known Aichi since the first time he stepped into Card Capital. In order to jolt Miwa's memories, Kai tries to re-enact his first epic battle with Aichi!

Only Kai, Naoki, and Misaki remember Aichi and they vow to find him, but are stumped. But then Morris, an enigmatic steward, appears in front of Naoki. As Morris engages in a Cardfight with Naoki, he tries to use the latter's anxiety to win the fight and throw him into despair. But who is Morris and his unseen master?

Now two people remember the otherwise-forgotten Aichi: Kai and Naoki. Can they succeed in reviving Misaki's memories through a Vanguard fight? And what is the secret of Kai's new move, Legion?

Aichi is nowhere to be found, but what's even more frustrating for Kai is that no one remembers him, not even his own family! Have Aichi's other friends totally forgotten about him or are there still glimmers of memory that can be unearthed? Determined to find out, Kai fights Naoki... for the first time?!

In the finale of the Link Joker arc, Aichi's epic battle with the Reversed Kai reaches its climax! Kai is determined to win and then disappear forever so he won't ever be able to succumb to evil again. Aichi is just as determined to save his friend, no matter what it takes!

Link Joker's power has been banished from Earth and all Reversed fighters have been returned to normal. But then why is Aichi in a desperate fight against Kai on the roof of Takuto's building? Whatever the outcome, Kai means for it to be their final battle!

It seems the end of the world is now, with Link Joker units brought to life, swooping down and stealing lifeforce from people, while hordes of Reversed fighters try to pick off the last of the un-Reversed. The gate will open completely as soon as Aichi is beaten by Dark Takuto... and though the odds are stacked against him, Aichi holds on to one last bit of hope...

Aichi is the only one who can keep the evil Takuto from attaining the end of the world... and it all comes down to a Cardfight! But now Aichi knows that if he wins, Kourin will lose everything...

It's the ultimate fight to the finish between Kai and Ren, but as the battle rages on, the Reversed Kai becomes... more like himself? Ren seems to have his opponent up against the ropes, but that's before Kai brings out his game-changer...

Below, Tetsu and Asaka ward off a swarm of Reversed fighters. Far above, a climactic rooftop battle is taking place between the Reversed Kai and Ren as Aichi is forced to stand on the sidelines. Can Ren save the world? Or does that even matter to him while he's fighting his former best friend and greatest rival?

Aichi vs. Kourin! Aichi vows to bring Kourin back to normal from her Reversed state, but she has her own reasons for wanting to win. Also, learn the truth behind Takuto's connection with Ultra-rare!

The true Takuto fights his double, who commands the power of Link Joker! While their fight rages on inside, Miwa, Misaki and the others battle a Reversed gang outside, whose power strengthens as the faux Takuto gets closer to winning...

When Takuto and Leon confront Takuto's Link Joker double, Leon is teleported to another room, where he's forced to fight a future version of himself. Specifically, a Leon who has given up and accepted the power of Reverse! Will the Leon of now be able to change his future, or is history (his story) doomed to repeat itself?!

The fight between Aichi and Kai ends here, and it looks dire for Aichi! Also, Leon Souryu shows up with an unlikely ally! And who... or what... is Link Joker?!

The voluntarily Reversed Kai reveals to Aichi and company why he went over to the "dark side"... and then they have a Cardfight! Kai has something to prove, but Aichi just wants his friend and former mentor back.
