In this world, everyone can use magic… and in a land called the Clover Kingdom, two young men, Asta and Yuno, strive to become the Wizard King, the greatest of all magic users. Asta and Yuno were abandoned together at a church in Hage, a village in the boonies, and lived as brothers from that day onward. For some reason, however, Asta never developed the ability to use magic, even when Yuno had already mastered wind magic. Now, at last, the boys are turning fifteen, the age at which children receive their own grimoires. Asta has high hopes that receiving his grimoire will awaken his latent ability to use magic, but when the time comes…

The grimoire that Yuno received was a legendary grimoire with a four-leaf clover. A bandit named Revchi comes to steal it, and Asta comes to Yuno’s rescue.

The masterminds behind the invasion reveal themselves, though their motivation remains unclear. Asta spends quality time with one of his heroes.

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!

Due to Nacht's spell, the Devil who has been granting Asta power since the beginning has appeared physically. To master his Devil powers, Asta must battle and defeat his Devil, and force him to submit. But Asta has other plans... Meanwhile, Yuno, Noelle, and the others grow stronger in order to take their revenge against the Dark Triad.
