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 help of the first Wizard King and the leader of the elves, Asta and Yuno now might have a chance against the Devil's unlimited power. But in order to put an end to this long battle, the two young mages will have to show strength that they've never shown before!
