Black Clover is a Japanese manga series written and illustrated by Yūki Tabata. The story centers around Asta, a young boy born without any magic power. This is unknown to the world he lives in because seemingly everyone has some sort of magic power. With his fellow mages from the Black Bulls, Asta plans to become the next Wizard King. It has been serialized in Shueisha’s Weekly Shōnen Jump magazine since February 2015, with its chapters collected in 28 tankōbon volumes as of April 2021.
Black Clover focuses on Asta, a young orphan who left to be raised in an orphanage alongside his fellow orphan, Yuno. While everyone is born with the ability to utilize Mana in the form of Magical Power (魔力, Maryoku), Asta with no magic, however, instead focuses on physical strength. Conversely, Yuno was born as a prodigy with immense magical power and the talent to control wind magic. Motivated by a desire to become the next Wizard King, an authority figure second to the king of Clover Kingdom, the two youths developed a friendly rivalry. Yuno obtains a legendary four-leaf grimoire held by the kingdom’s first Wizard King. The four-leaf grimoire is a rare grimoire, only given to the most immense mages. Asta, despite his lack of magic, obtained a mysterious five-leaf grimoire that contains mysterious elf swords and a bodiless member of the Devil race who utilizes rare anti-magic. Afterward, he and Yuno each join a Magic Knight squad as the first step to fulfill their ambitions.
Asta joins the Black Bulls alongside Noelle Silva while Yuno becomes a member of the Golden Dawn, embarking on various adventures while contending with an extremist group called the Eye of the Midnight Sun whose leadership is manipulated by a Devil in avenging an injustice committed against the Elves by the Clover Kingdom at the time of its founding. The Magic Knights then face the Dark Triad of the Spade Kingdom, with Asta and Yuno learning of their Devils’ influence on their lives and of the Dark Triad’s plan to fully manifest the Devils into their world.
