The unexpected stalemate at the Iserlohn Corridor urges the Imperial Headquarters to muster a reinforcement fleet to be immediately sent in support of Reuenthal. Or at least this is what the Imperial crews believe... but as the fleet jumps out from subspace, it becomes clear that Iserlohn is not their destination.

The Magic Knight Squad Captains end up doing a team battle due to Julius's suggestion. Since the citizens are still weary after the attack by the Eye of the Midnight Sun, they want to prove that they still mean to protect the kingdom and its citizens. The Magic Knights watch in anticipation as their captains split up into two teams and go all out in this battle.

To prepare for the upcoming battle against the devil, the Black Bull Grey decided that she needed to get over her shyness and be able to face her friends first before anything else, so she asked Noelle to mentor her. However, things aren't going very well. Next, Grey tries to get Gauche to help her, since they had fought together in the past. For this training, she walked around town with him when it was crowded, but then they saw a panicked Charlotte run by...

The incident with the Devil Believers had come to a close. This whole incident ends up hurting Nero, who witnessed the pain the Devil Believers felt from having less mana and reminds her of her time with the first Wizard King, Lumiere and the magic item he was trying to create to get rid of discrimination in their kingdom. She then gets summoned by Julius. Meanwhile, Asta and the others receive a message saying that the Heart Kingdom and the Spirit Guardians were ready to train them for their fight against the devil.

Asta and Noelle are captured along with Nero and they head toward the strong magic region near the border when Captain Yami and Magna arrive. Captain Fuegoleon and Captain Nozel also show up, causing the Devil Believers to panic. The captains try to talk to the Devil Believers, but their distrust for them is just too strong. The Devil Believers try to bring their powers together in order to face the Magic Knight captains.

Asta, Noelle, and Magna manage to catch up to the Devil Believers who had taken Nero. But they find that the Devil Believers have now grown in numbers. Magna goes back to tell Yami of the situation. Asta and Noelle are left behind and try to do what they can to save Nero. But it appears that the Devil Believers have made up their minds on achieving their goal, even if it costs them their lives.

Though the Magic Knights were able to save Marie from the Devil Banishers, Nero is taken once again and Asta’s 5-leaf clover grimoire is also stolen. Suddenly, they receive a message from one of Damnatio’s subordinates and learn the true identities of the Devil Banishers and Julius orders the Black Bulls yet again to save Nero. The Black Bulls begin their investigation in the town where they think the Devil Banishers were gathering. Will they be able to find out what the enemy’s true motive?

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.

Julius orders the Black Bulls to save Nero and Marie, so Captain Yami, Noelle, Finral, Gordon and Gauche travel to a certain town along with the captain of the Silver Eagles Nozel, to see if they can find any clues. They try to ask the townspeople for some clues, but it appears that they are less than willing to cooperate because they seem to hold a grudge against the Magic Knights who weren’t able to come to their immediate aid after they were attacked by the elves.

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.

While the Clover Kingdom was trying to get back onto its feet, the citizens learn that the one behind the destruction of their homes is called the devil, and many of them grew to hate the devil. Some of these people had gathered and created a group called the Devil Banishers. Because the Magic Parliament did not immediately punish the supposed servants of the devil, they decide to go after Asta and Nero and take matters into their own hands.

The Golden Dawn was hard at work trying to get the kingdom back onto its feet. They were trying to make amends for the trouble they had caused while they were possessed. Captain Vangeance puts Alecdora Sandler in charge of a mission. Alecdora can’t hide his dislike for Yuno so he tries his best to earn more merit than him.
