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.

Asta and Yuno head toward the colosseum in the royal capital for the Magic Knights Entrance Exam, while looking around and admiring all the things they’ve never seen before.

Asta has arrived at the home of the Black Bulls, which Yami himself called the absolute worst Magic Knights Squad. He is greeted by the squad’s unique members.

The Diamond Kingdom’s secret weapon wields more powerful magic than anyone has seen. The Golden Dawn team is all but decimated. Can he be defeated?

The Black Bulls seem to be on the losing end of an epic clash between two highly gifted magic users. Gauche has an idea that could turn the tables.

Asta undergoes a startling transformation, fighting like a man possessed. When he learns who’s behind this change, he also learns its shocking price.
