Asta and Yuno are orphans raised in the outskirts of the Clover Kingdom. In a world where people are born with magic, Asta was born without any. In comparison, Yuno was born a prodigy with above average magic power and the talent to control it. Additionally, in their coming of age ceremony, Yuno receives a rare four leaf clover grimoire, like the original Magic Emperor. On the other hand, Asta received a tattered grimoire where a Devil lies within, a five leaf clover grimoire.
