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!

He offers to show Asta how to use his devil powers even better. Meanwhile, the Magic Knight Squad Captains hold an emergency meeting. The Golden Dawn has almost been completely annihilated, and Yuno shows up to the meeting, showing new resolve.
