Black Clover, Volume 17 (by Yuki Tabata)

In a world of magic, Asta, a boy with anti-magic powers, will do whatever it takes to become the Wizard King! Asta is a young boy who dreams of becoming the greatest mage in the kingdom. Only one problem—he can't use any magic! Luckily for Asta, he receives the incredibly rare five-leaf clover grimoire that gives him the power of anti-magic. Can someone who can't use magic really become the Wizard King? One thing's for sure—Asta will never give up! With the elves having taken control of many of their allies, Asta and the Royal Knights are in big trouble. Can Mereoleona lead the remaining knights to victory? And where exactly does Yuno stand in this battle?
