Declan and Celina recall that they once met each other three years ago when Declan accidentally stumbled into Duel Academy. Declan came across Celina and helped her to escape from some of Leo's guards, but they were soon caught by Leo, who took Celina away before explaining everything about the different dimensions to Declan before sending him back to Standard. As Declan tries to reason with Celina, who wants to prove her worth to Leo by defeating Xyz Duelists, Barrett activates a device on his Duel Disk, alerting Duel Academy to his position before teleporting back there, while Celina takes her leave. Back at Duel Academy, Leo sends Sora on a mission to capture Celina. The next day, Yuya and the other remaining duelists learn that the championship's third round will be a Battle Royal across the entire city, in which duelists can obtain Pendulum Cards. This is revealed to be a plan by Declan to distract the Junior Youth duelists while the Senior class fight against any invaders.
