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 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.

Yuno never expected his last-minute detour to involve such tragedy. It’s up to the Golden Dawn to get the bottom of their mission’s many mysteries.

Fanzell meets Asta again once Asta’s joined the Black Bulls, but this time he’s far from alone. In the present, Vanessa seeks a cure for Asta’s curse.

Asta confronts his rival, Yuno, one of many Golden Dawn members to have been taken over by elves. Licht is spurred to action, as are Yami and Finral.

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!

While Asta and the others were training in the Heart Kingdom, back in the Clover Kingdom, Yami asked Mereoleona to help him train.

To master his Devil powers, Asta must battle and defeat his Devil, and force him to submit. But Asta has other plans...
