After being attacked by the Devil Banishers, Nero as well as Gauche's younger sister, Marie, were kidnapped and Asta fell into a mysterious coma. Gauche thinks that maybe the head of the Magic Parliament, Damnatio, may have taken his sister, but Damnatio denies the claim. Damnatio's innocence is proven by using Marx's communication magic, but they learn that there's a possibility that Damnatio's subordinates are behind this incident. Meanwhile, Asta was taken to Owen's clinic and it becomes apparent that the tracking device he had on his arm had disappeared. They then find its signal coming from somewhere rather unexpected.

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.
