Black clover
 

Asta is a determined young boy who lives with his childhood friend, Yuno, in an orphanage in Clover Kingdom. From a young age, Asta's ambition was to become the most powerful magician in the kingdom, "Emperor-Mage", which also inspired Yuno to want the same. But unfortunately, Asta was born without any magical talent, while Yuno has spectacular predispositions.

When they reach their 15th birthday, all the young people of the kingdom are invited to a ceremony where they are given their grimoire ː while Yuno receives the legendary grimoire with a four-leaf clover, considered a myth since legend claims that the first Emperor-Mage also used a grimoire bearing a four-leaf clover, Asta receives nothing. After the ceremony, Yuno is attacked by a bandit who wants to steal his grimoire and then try to sell it.

Asta leaves to save him but finds himself in trouble, luckily he is saved by a mysterious grimoire with a five-leaf clover and a large rusty sword, which symbolizes the demon.

Asta and Yuno both promise to fight for the title of Emperor-Mage. As their paths separate on the Knight-Mage route, their goal is still the same: to become the next Emperor-Mage.
