The battle involving the whole Clover Kingdom is finally over. But because of the battle, the kingdom was heavily damaged, so the Magic Knights were busy trying to repair everything. Meanwhile, someone rather unexpected shows up in front of Asta and the others and states three problems that will come up for the Clover Kingdom. Asta and the others are surprised, but just as they were told, someone showed up to try to judge Asta and his devil power.

The Shadow Palace begins to shatter, but Asta and the others manage to escape. Meanwhile, the elves continued to attack the kingdom because they still didn’t know the truth. Asta is the only one who can undo the resurrection, but it won’t be easy to save all of them at once. Patry then frees Vangeance, who’s sleeping inside him, so he can use his world tree magic and Licht can use his magic that connects him with all of the elves and Asta is able to undo the resurrection of all the elves at once. Finally, the long battle is coming to an end.

Licht and Lumiere fight against the devil using incredibly powerful magic. But the devil has incredible regeneration powers and quickly heals himself, making him difficult to defeat. Asta witnesses the two powerful mages fighting and tries to figure out if he can use his anti-magic in a more useful way. He’s able to use a new power, but it’s so powerful that he’s having a hard time controlling it. Meanwhile, Yuno also awakens to a new power... Asta and Yuno, who both aspire to be the future Wizard King, pull off an impressive attack in front of the first Wizard King!

To stop the devil from leaving the Shadow Palace Asta, Yuno, and Patry, who had just regained his senses, head to the top floor. Once they get there, they are greeted by the first Wizard King, Lumiere Silvamillion Clover and the one who serves him, Secré Swallowtail。Secré is the true form of the mysterious bird, Nero, and she is a mage that uses a rare magic called sealing magic. She uses her magic to break the seal on Licht, and they are able to witness the true leader of the elves, Licht, and his true powers. An epic battle begins so that Licht and Lumiere can get revenge against the devil.

The strange little black bird Nero, who kept following Asta around, suddenly appears before Finral, who had just finished fighting with his brother Langris, and demands that he take them to the Demon’s bones back in Hage Village. Finral is obviously startled that Nero’s suddenly speaking human words but obliges and takes Nero to the bones and witnesses an unbelievable sight. We will finally find out the true events that befell the elves 500 years ago! Meanwhile, back at the Shadow Palace, the devil’s eerie magic fills the room.

“When the owner of the four-leaf grimoire is filled with despair, the five-leaf clover grimoire will be born.” Patry is filled with despair after learning he had been manipulated by the devil all this time and turns into a dark elf. He then starts attacking Yuno and Asta, fueled by nothing but hatred and malice. Somehow, becoming a dark elf had made Patry even stronger, which gives Yuno and Asta an even harder time fighting him. Then Captain Nozel appears before them. Nozel happens to have the best magical attribute to fight against light magic, mercury magic.

Yuno manages to enter the Shadow Palace with his pendant and runs into Patry and the others. However, his pendant is immediately stolen. Now, all of the necessary magic stones have been collected and the elves’ wish was supposed to come true. However, an uninvited guest appears before them: A devil from another world. They find out everything that happened between the elves and humans were actually a part of his plan all along. Yuno can’t hide is astonishment at how powerful the devil is as he tries to fight it, and then Asta and Mimosa also arrive!

The Black Bulls fight off the elves as Asta and the captains head into the Shadow Palace. However, they start to feel cornered from being so run down from one battle after another. It was then that Yuno had finally arrived to save them, bringing other Magic Knights he found throughout the land with him. Yuno hears the situation from Charmy and decides to head into the Shadow Palace, too. However, the entrance was now closed. But then, his pendant starts to react in a strange way...

After their last battle, Asta and some of the others decide to chase after Captain Yami and some others who had already headed into the Shadow Palace. However, the elves get in their way. It was then that Captain Fuegoleon and Captain Mereoleona, both who had just awakened, showed off their true powers. Asta and the others are happy to have their help, but then notice that the door to the Shadow Palace closing. In order to get Asta and his group into the palace, the other Black Bulls hold off the elves outside.
