At the center of X City rises the imposing X Tower, a connected twin-skyscraper complex that represents the ultimate aspiration for every Beyblade player. The structure functions as the official headquarters for professional Beybattles, where competitors aim to conquer all one hundred floors; at the top, the reigning champions, Team Pendragon, wait for challengers worthy of testing their title. Bird Kazami, an amateur Blader, comes to the city hoping to go pro. However, he and his teammates suffer a crushing defeat in their first qualifying match, causing his companions to quit and dissolve their team. Luckily, Bird is soon contacted by the laid-back Ekusu Kurosu. Hiding his past as a member of the undefeated Team Pendragon behind the alias "Kamen X," Ekusu wishes to climb the tower once more. To finish assembling their new squad, they bring in Multi Nanairo, a skilled Beyblade expert and savvy social media influencer. Motivated by their personal objectives, the trio wins their preliminary rounds, beginning their journey as Team Persona. Bird and his new allies must handle corporate sponsorships, win over the unpredictable public, and overcome numerous strong opponents—all in their pursuit of reaching the summit of X Tower.
