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. Zax confronts Asta about dispelling all of his traps, which Asta responds by telling "Zax" to come up with a plan for them. Zax tells Asta to just defeat the enemy team himself, but Asta replies that he has to recoup before using that technique again. Asta also says that he wants to fight as a team and then explains why they are all taking this exam. Zax remembers when someone told him about how amazing the magic knights are, and tells Asta that he won't have a friendly match with royalty but he will make use of Asta for his own objectives. Asta says that he is fine with that, as long as they get to fight as a team. Zax then explains why magic and abilities that he is capable of using, and what he is able to do right now.

At Team C's location, Kirsch comments about how his magic was sullied by Asta which Magna says that he knew that would happen. Magna says that he knew that Asta was practicing for the exam and that they should underestimate commoners since he is one too. Kirsch is shocked by this and says that he will not be tainted. Kirsch then heads out to face Team B allow, while telling Sol and Magna to guard the crystal. While heading towards Team B, Kirsch thinks about how commoners are all filthy because of their low magic power and how he will never stand on the same stage as them.

Kirsch notices where both Zax and Mimosa are but wonders where Asta is since he can't sense him. Asta suddenly appears before Kirsch, which Kirsch uses Dance of 100 Million Cherry Blossoms to attack Asta with. Asta tries to defend against the spell but Dance of 100 Million Cherry Blossoms manages to slip past his defenses. Asta quickly escapes to a cave, but Kirsch notices that is a trap since he sense magic on the ground. Kirsch uses Clones of the Beautiful Me to set off the traps and heads into the cave. Kirsch prepares to attack Asta but suddenly falls into a pitfall trap. As Kirsch is confused about what had happened, Zax explains how Kirsch fell into a non magic made trap. Kirsch says that he can easily fly out of the trap but notices that Asta is above his. Kirsch tells Asta to stay away and launches a spell at Asta but it is dispelled by Asta swords. Asta then crashes into Kirsch and defeats him.
