Asta and Yuno were abandoned at an equivalent church on an equivalent day. Raised together as children, they came to understand of the “Wizard King” a title given to the strongest mage within the kingdom and promised that they might compete against one another for the position of subsequent Wizard King. However, as they grew up, the stark difference between them became evident. While Yuno is in a position to wield magic with amazing power and control, Asta cannot use magic in the least and desperately tries to awaken his powers by training physically.
When they reach the age of 15, Yuno is bestowed a spectacular Grimoire with a four leaf clover, while Asta receives nothing. However, soon after, Yuno is attacked by an individual named Lebuty, whose main purpose is to get Yuno’s Grimoire. Asta tries to fight Lebuty, but he’s outmatched. Though without hope and on the brink of defeat, he finds the strength to continue when he hears Yuno’s voice. Unleashing his inner emotions during a rage, Asta receives a five-leaf clover Grimoire, a “Black Clover” giving him enough power to defeat Lebuty. a couple of days later, the 2 friends head out into the planet , both seeking an equivalent goal to become the Wizard King!
