Biography
"Xerx" discovers the location for the Royal Knights Selection Exam and spends the night placing Trap Magic across the battlefield.

The next day, a mysterious man confronts Xerx Lugner and another Violet Orca and insults the vice-captain. Xerx then attacks the man with Ice Magic but is defeated, and the man removes Xerx's squad robe. Later at the exam, Xerx is teamed up with Mimosa Vermilion and Asta, but the mysterious man arrives and takes the spot, claiming to be Xerx.

He explains his tardiness to Julius Nova Chrono while patting the Magic Emperor on the shoulder. Angered by the disrespect, Marx attacks "Xerx," who dodges the Magic Bullet and lands in the arena with the other Magic Knights. They angrily yell at him for his arrogance, and "Xerx" reveals that he does not respect Julius, which further angers them. "Xerx" introduces himself to Asta and plants a stink bug in his hand. Asta asks if he has any intention of getting along, and "Xerx" replies with insults and reveals that he came to mock the other Magic Knights.

As the first match of the tournament begins, "Xerx" admonishes Asta for being too hasty and not taking it seriously. Mimosa tries to calm them down when their crystal is suddenly struck. As Mimosa and Asta prepare to fight back, "Xerx" falls asleep, claiming that he did not sleep much the night before and that he does not care if they lose.

A trap placed by "Xerx" in the middle of the field paralyzes Asta when he steps on it. Team B launches three powerful spells at the defenseless Mimosa and Asta, but a secondary trap absorbs and reflects the spells back at their casters. "Xerx" then wakes up and approaches Team B's crystal, which Curtis Warren barely protected. He compliments Curtis for surviving but steps on the Silver Eagle on his way to the crystal. When Curtis objects, "Xerx" criticizes him for losing and his poor fighting strategy. "Xerx" decides not to destroy the crystal, claiming to have different goal, but then spins around and smashes it.

After Kirsch Vermilion leads his team to victory, "Xerx" quietly watches the Coral Peacock's display.

"Xerx" is perturbed when Julius has the battlefield rearranged for the second round. Before the ninth match begins, "Xerx" is focused on facing Kirsch and suggests that his team work together. When Asta points out that "Xerx" was bothered by the field change, "Xerx" realizes that Asta can sense Ki, and admits that he placed traps around the battlefield. Asta claims that it is cheating, but "Xerx" counters that gathering information is an important skill and that there are no rules against it. Asta asks for him to tell where the traps are, but "Xerx" refuses because they might give away their locations.

As the match begins, Kirsch covers the battlefield with cherry blossoms and "Xerx" is content to wait and let Team C fall into his traps. He is surprised when Asta coats himself in Anti Magic and destroys the cherry blossoms and the traps. "Xerx" questions Asta's motivation, and the boy suggests that they work together, to the rogue's annoyance.

Asta insists that "Xerx" come up with a new plan. The rogue refuses and points out that Asta could win on his own with his ability, but Asta happily reveals that he needs to rest before using it again. "Xerx" questions why the boy is happy about that, and Asta responds that he wants to fight alongside everyone, which reminds "Xerx" of someone saying the same thing before. Asta points at "Xerx" and reminds him that Kirsch is a royal and powerful. "Xerx" squeezes the boy's finger and tells him that he will not fight for a friendly match with royalty but for his own goals, and that he has no choice but to use Asta. "Xerx" then explains to his teammates about his Ash and Trap Magic.

As Kirsch flies across the battlefield, he senses the rogue's mana off to the side, where "Xerx" is setting up traps outside of an alcove. After Asta leads Kirsch there, the Coral Peacock triggers the traps with his clones, but as he walks closer, he drops into a non-magical pitfall. "Xerx" laughs at Kirsch for relying too much on his mana sensing. After Asta knocks Kirsch unconscious and lays his Demon-Slayer Sword atop the royal, "Xerx" places a trap next to the pitfall, in case Kirsch escapes or one of his teammates comes to rescue him. "Xerx" also collapses the cave's entrance, which alerts Magna to their location. "Xerx" asks Asta to hold Magna off for five minutes while he draws a magic circle. Just as "Xerx" finishes the trap, Kirsch emerges from the cave, so the rogue orders Asta to deal with Kirsch and places his trap on the crystal. When Magna's fireball strikes, it is absorbed and reflected back at Magna, who is knocked out when the spell jumps, avoiding his swing.

When Kirsch draws his hand back to attack Asta, he trips a binding trap that "Xerx" placed midair, and Asta knocks Kirsch out again. "Xerx" and Asta are then surprised when Sol bursts from the ground and tries to attack the crystal. Mimosa's spell then disables the golem, allowing Asta to destroy it and Team C's crystal. As Asta celebrates their victory, "Xerx" critiques Team C, being especially harsh to Kirsch.
