Asta vs. Revchi Salik

Asta vs. Lebuty is a fight that occurs in the aftermath of the Grimoire Acceptance Ceremony.

Pre-fight
After Yuno receives the four-leaf grimoire at the acceptance ceremony, Lebuty, who is among the attendees, plots to snatch it from him. At dusk, Yuno, standing in front of the venue, is ambushed with chains that bind him down.

Lebuty appears in front of him as he catches Yuno's grimoire while revealing his plan on selling the grimoire at the black market. At the same time, Asta witnesses the whole scene from afar at the top of a tree.

Fight
Seeing Yuno is in trouble, Asta quickly rushes toward him. Realizing that the boy is the one who failed to receive a grimoire, Lebuty gives Asta condescending comments. Asta tries to reason with Lebuty but fails to convince him. Thus, he dashes toward him but is quickly taken down by Lebuty's magic spell. As Asta is settled against the wall, Lebuty starts throwing comments to reduce Asta's fighting spirit, which begins to affect Asta until Yuno interrupts him. Yuno completely denies everything that Lebuty has said and confirms the rivalry he has with Asta.

Yuno's confession encourages Asta and brings back his will to fight. Suddenly, a grimoire tattered and covered with dirt appears in front of Asta from a hole on a wall. The grimoire summons a sword in front of him, after which Lebuty realizes that the grimoire possesses a five-leaf clover at its cover. Knowing the potential danger that the grimoire possess, Lebuty immediately launches an attack, but Asta takes a hold on the sword and swings it against Lebuty's magic attack and negates the said attack. Subsequently, he delivers a wide slash at Lebuty's torso and sends him flying against the wall. Afterward, Lebuty seems to have lost his consciousness.

Post-fight
Asta pampers his new grimoire as Yuno approaches him after Lebuty's spell vanished. As Yuno promises to pay his debt to him someday, he asks whether Asta remembers the promise they made at one point during their childhood. Asta confirms that he remembers as they bump their fists while reciting their promise to become the next Magic Emperor.
