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! 
In the battle for humanity, Yami, Nacht, and Yuno give it their all against the king of devils, but it may not be enough. It'll be up to Asta and Leibe to surpass their limits together and finally avenge their mother!
