To become a pro, amateur blader Bird Kazami comes to the sacred place "X City." However, he is defeated by rookie crusher Takumi Ishiyama. Abandoned by his teammates, Bird is approached by a mysterious blader, Kamen X, who invites him to join his team. What is the true identity of the one who unleashed the "Xtreme Dash" with super-speed? The battle begins as Bird aims for the summit of the "X Tower," where powerful bladers gather!

Inspired by Kurosu X, who attempts to aim for the top of X Tower from scratch once more, Bird's heart is filled with determination. As his passion to fight ignites, a mysterious person appears before Bird who is worried for losing his bey and being unable to participate in battles. But in reality, this person offers to lend him a bey!? And as the two set their sights on becoming pros in the "Pro Selection Tournament," they encounter a skilled and popular blader who can master Beys with both popularity and strength, Multi Nanairo, who stands in their way!

Bird believed that "If it's Kamen X, he can beat Multi Nanairo." However, Multi Nanairo had already studied Kamen's fighting style and would come to win with an advantageous strategy, transforming with a new Bey! Faced with a fully prepared Multi Nanairo, Kamen not only didn't hesitate but declared an unexpected instant victory...!? In this challenging battle, he unleashed the ultimate Extreme Dash, but can he truly defeat Multi Nanairo and advance "Team Persona" to the professional level...!?

In the professional selection match, Kamen X, who won, recruited Multi to the team. Bird, who was thrilled to officially become a professional, found out that they needed a sponsor. They received an offer right away, and the place where the sponsor's company was located turned out to be a sushi restaurant that had been established for 200 years! Can Bird and the others pass the final sponsor test and become sponsored successfully?

Team Persona, who officially became a pro team, finally heads to X Tower. In the exclusive pro area, they feel the tension of potentially losing everything if they keep losing and are excited by the powerful battles with 4X avatars. As they practice battles in the pro-exclusive area, their motivation for the first match increases. However, as the rival team's match results are announced, Bird is shocked to discover that the winning team of that battle will become Team Persona's first opponent.

In their first professional battle, Team Persona, set to face the team "Zooganic" led by King Manju. They infiltrate the zoo "Lion's Jungle" operated by the sponsor. Despite their covert approach, Team Person is discovered by the sharp sense of smell of the leader, King. With zoo visitors watching, the provoked Team Persona boldly steps forward in front of King. Unexpectedly, members of both teams confront each other, leading to a tense situation.

Persona, who is finally facing their professional debut match, steps onto the stage of their long-awaited dreams. Bird sets foot on the stage for the first time, overwhelmed by the scale of the venue and the cheers erupting around. As both team members confront each other on stage, the first breaker is decided, and the confrontation with Zooganic begins! Can Toguro Okunaga, who sets up psychological tactics even before the battle begins, Cho Pan, with unknown strength due to a lack of data, and the overwhelmingly powerful King Manju be defeated?

Kamen X, boasting an undefeated record in official matches, faces off against King Manju, two formidable powerhouses crucial to the teams.

As powerful shots are unleashed, a high-stakes battle unfolds at the 4X Stadium, escalating the intense rivalry between Persona and Zooganic. The fate of their pro debut showdown hangs in the balance!

After finishing their debut battle and gaining attention, Persona, in their first professional request, engaged in a demonstration battle at the Bey Café. The battle, requested for both Kamen X and Multi, aimed not only to win but also to showcase a captivating performance as a professional. Multi created a new Bey to draw out Bird's true potential. Can Bird, who has had no notable successes so far, truly shine this time?

In Persona's second pro match, Bird faces Phalanx, where Takumi Ishiyama, who destroyed Bird's Bey in his amateur days, belongs. Bird witnesses Ishiyama's plight as he struggles to meet sponsor demands just before the match. Meanwhile, Kamen X is excited about the opportunity to aim for a triple knockout in the tournament. As the match begins, Kamen X reveals a surprising fact to Phalanx, who has prepared thoroughly for the Dransword.

In order to clear the first floor of X Tower, the team must pass the "Kadovar's Test"! Unfortunately, Bird fails. To overcome Persona’s weaknesses, at Taisho's suggestion, Bird is sent alone for training at a camp facility. Unexpectedly, Ekusu joins, and they train together. Though bewildered by Ekusu's pace, Bird continues practicing to pass the exam. Will Bird be able to succeed in the end?

The members of Persona participate in the "Single Battle Fest" for individual matches. Maruko Carlo, who faces Bird on stage with unexpectedly serious intensity, demands a "serious battle" for a specific reason. Carlo unleashes the full power of the Bey Bird once used, displaying strength that belies his imminent retirement. Carlo reveals the reason for seeking a "serious battle" from Bird after the match.

In the world of Persona, Bird was the only unpopular one, but during an errand, a girl who claimed to be his fan appeared. While excitedly providing fan service, Bird gets entangled with Bladers who approach him with malicious intent. Ridiculed not only personally but also along with other Persona members and sponsors. Bird, in order to defend the honour of his teammates, is challenged to a no-rules street battle where anything goes. Faced with opponents using dirty tactics, how will Bird confront them?
