Black Clover Vol 21

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 Asta and Yuno now in the Shadow Palace, the time has finally come to settle the grudge with the elves that has lasted hundreds of years. However, when the true dark force behind everything makes his appearance, the entire direction of the battle will shift dramatically!
