The Devil Banishers announce that they will judge Nero and Marie in public. Julius then orders the Black Bulls and other Magic Knights to go rescue them. The Magic Knights place themselves among a crowd that clearly hates the devil, and then the Devil Banishers appear. They then demand that the devil-possessed Asta show himself.

The Magic Knight Squad Captains end up doing a team battle due to Julius’ suggestion.

The Magic Knights watch in anticipation as their captains split up into two teams and go all out in this battle.

Meanwhile, Yuno, Noelle, and the others grow stronger in order to take their revenge against the Dark Triad.
