Team B vs. Team C

Team B vs. Team C is the ninth fight of the Crystal Destruction Battle Tournament.

Pre-Fight
Julius Nova Chrono his his several mages rearrange the battlefield, and Asta notices that it irks "Zax". As Team C makes their way over, Kirsch Vermilion claims that his beauty will never change nor will the fates of the ugly, but Asta and Mimosa Vermilion disagree; Magna Swing challenges Asta, who agrees.

"Zax" contemplates fighting Kirsch and then suggests that his team show teamwork. Asta points out that "Zax" was not happy when the battlefield changed, and asks if he had traps already set up. Noting that Asta must be able to sense Ki, "Zax" admits that he found out the location of the exam ahead of time and placed several traps the day before. Shocked that he could find out such information, Mimosa questions who he is, while Asta yells that strategy is unfair. However, "Zax" points out that collecting information is also part of war and that the rules say nothing about it, which frustrates Asta. The boy asks for the locations of the traps, but "Zax" refuses because their opponents might be able to read their movements.

Fight
As the match begins, Kirsch covers the battlefield with Magic Cherry Blossom Blizzard. Mimosa struggles to find an opening in the magic, and "Zax" decides to wait for the opponents to step in his traps. Not willing to wait, Asta draws on Anti Magic from the Demon-Slayer Sword, partially transforming, and spins rapidly, creating a small, black vortex of Anti Magic. Several slashes fly across the battlefield and cut through Kirsch's Cherry Blossom Magic and clones and Zax's traps, dispelling them, much to Zax's and Kirsch's shock and anger.

As the Anti Magic dissipates from Asta, Mimosa compliments him while Zax yells at him. Asta points out that Zax is finally speaking genuinely, and suggests that they work together.
