Black Clover (Series)

On the same day, Asta and Yuno were left behind at the same church. Having grown up together, they learned that the strongest wizard in the realm is referred to as the “Wizard King” and made a deal that they would fight it out to become the next Wizard King.

But as they grew older, it was clear how different they were from one another. Asta is completely unable to use magic, although he makes a valiant effort to reawaken his abilities through physical training. And Yuno, on the other hand, is a prodigy who can use magic with incredible force and control.
