Plot
Asta, a boy born with no magic in a world where magic is everything, and his rival Yuno, a genius mage chosen by the legendary 4-leaf Grimoire, have together fought a number of powerful enemies to prove their power beyond adversity and aim for the top mage "Wizard King".

Conrad Leto, the former predecessor of Julius Novachrono, once commanded the respect of the people in the Clover Kingdom. However, he unexpectedly turned against the kingdom and was subsequently sealed away by Julius himself. Now, Conrad has resurfaced and he wields the "Imperial Sword" and seeks to destroy the Clover Kingdom and bring forth a new era where equality prevails by destroying all and reviving only those whom he considers deserving of a place in his envisioned society.

He uses the power of the sword to revive three wizard kings of the past: Edward Avalaché, Princia Funnybunny, and Jester Garandaros, who share the same vision as him, in order to achieve his goal.
