Asta (Japanese: アスタ, Hepburn: Asuta) is a fictional character and the main protagonist of the manga series Black Clover created by Yūki Tabata.

He has no magical power, but overcame this through intense physical training which allow him to wield anti-magic swords from a five-leaf clover grimoire in which a devil resides.

In the Black Clover anime adaptation, he is voiced by Gakuto Kajiwara in Japanese and Dallas Reid in English.

Asta was originally the subject of mixed responses due to his characterization coming across as archetype and the tone used by Kajiwara.

After she does so, he goes on to help defeat Third Eye member Fana and Diamond soldier Ladros, using his new Black form from the Witch Queen using her blood magic to increase the anti-magic circulation in his body.

However, the Witch Queen uses her magic to command Asta to kill his friends, which is stopped by Vanessa using her Red Thread of Fate.

At the Shadow Palace, Asta brings Patry out of his despair after the true mastermind of the elf massacre is revealed to be the devil Zagred, convincing him to atone for his misdeeds and help defeat their common enemy.

When Sister Lily, Heath Grice, and Yrul invade the Land of the Sun, he finishes up his training and stops them with the help of the Ruyzen Seven.

He is later brought back to the Clover Kingdom with Ichika, easily defeats Damnatio, and gives the Black Bulls some of his anti-magic.
