Asta and Yuno were abandoned together as babies in baskets at the same church on the same day, and have been inseparable since. As children, they promised that they would compete against each other to see who would become the next Wizard King. However, as they grew up, some differences between them became plain - Yuno was a magical prodigy, while Asta could not use magic at all. In a country where magic is everything and athletic ability is nothing, Asta tried every day to provoke even the simplest magic out of himself with physical training and loud proclamations of his will.
