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.

Asta and Noelle go to see the Magic Knight Entrance Exams with Yami. The testing site and the anti-birds that gather there are rather nostalgic to Asta and remembers his own experience at the exams last year after seeing the hopefuls from this year.

Asta and Yuno were abandoned together at the same church and have been inseparable since. As children, they promised that they would compete against each other to see who would become the next Emperor Magus. However, as they grew up, some differences between them became plain. Yuno was a genius with magic, with amazing power and control, while Asta could not use magic at all, and tried to make up for his lack by training physically. When they received their Grimoires at age 15, Yuno got a spectacular book with a four-leaf clover (most people receive a three-leaf-clover), while Asta received nothing at all. However, when Yuno was threatened, the truth about Asta’s power was revealed, he received a five-leaf clover Grimoire, a “black clover”! Now the two friends are heading out in the world, both seeking the same goal!

Yami strikes Dante what should have been a mortal blow, but he recovers quickly with the Power of his Devil. Asta witnesses his own Devil seethe in frenzy. In the Heart Kingdom, Charmy and Leo battle more Dark Disciples.
