After the Black Clover 332 celebrations, it's time for the Magical Knights to find out the truth. The magical kingdom is on the verge of a new solar eclipse, the worst ever. Will Asta and the others be able to handle this umpteenth catastrophe?
Just like William Vangeance with the elf Patry Julius Novachrono hid his alter ego. The Magic Emperor's soul was inhabited by Lucius Zogratis, who managed to gain control by acquiring the power of the Heart of Lucifer.
Black Clover 333 picks up where the previous chapter left readers. Asta encounters what is said to be the Magic Emperor. However, the Black Bull's magician recognizes this immediately what is before him is not Juliusbut a frighteningly evil-looking creature.
Time stands still all around. Only Asta, with his anti-magic and Devil Union with love, manages to break free from the enemy's control, who eventually reveals his identity. What Asta has in front of her is Lucius Zogratis, the savior of the world who attained the power of Lucifer. Julius Novachrono is dead and Lucius claims to become the final Magical Emperor.
But Asta doesn't fit. Julius couldn't have died that easily and will do anything to stop Lucius and then save the true Emperor. When the antagonist claims to be even stronger than Novachrono, Asta promises it go beyond your limits and become even stronger than them.
