Black Clover is a breeding ground for fan theories and speculations. Future developments and potential connections between characters become wild guesses and even become the subject of heated debates among those in the anime/manga communities. From the information available, and without dropping too many spoilers, conspiracies, pairings, and royalty come to light.
Not all theories are mind-blowing, but most will make fans do a double-take. Circumstantial evidence is all we need to make events connect and build upon one another in a snowball effect, even if the starting point is shaky at best. It's one of the various joys of anime fandom that people from all over the world partake in. As Captain Yami often says, "Surpass your limits. Right here. Right now," and those of the Black Clover fandom do not disappoint.
10 Noelle Wins Asta's Heart
Fans within the anime community have no restraint when it comes to shipping their favorite characters together, no matter how ridiculous the pairing appears. While the theory of the end-game couple is up in the air, the most possible pairing with Asta is Noelle.
It's not all pure speculation but is based on their character development and nonchalant confessing of their feelings for each other. Asta's heart is pure, which makes him oblivious to romance unless it concerns his beloved sister Lily. Couples who slay together stay together, although, with Asta and Noelle's character development, it remains to be seen.
9 Sally Becomes A Member Of The Black Bulls
Originally conspiring with the Eye of the Midnight Sun, Sally is a scientist at heart. She's insanely curious about Asta, his lack of magic, and his grimoire. Sally is not evil at heart, so when Asta offers up his body in the name of scientific experimentation in return for her help, she readily agrees.
After the showdown against the elves, Sally is willing to change her ways if it means she'll be able to experiment on her heart's content. Not to mention, Captain Yami has no qualms with allowing an oddball or criminal into his squad, as seen with Gauche and Grey.
8 Asta's Mythical Connection To High Demon Astaroth
In common demonology, Astaroth is considered a Grand Duke of Hell, and in modern religious practices, he's a part of an evil trinity, along with Beelzebub and Lucifer. It's also thought that Astaroth is able to command legions of demons.
Thus far, Charmy has been revealed to be part dwarf, so it stands to reason that Asta might be part demon. This leads to the conclusion that if Asta has demon blood, and therefore no mana, then in exchange he'll have control over demons. Wild, right?
7 The Water Spirit Will Become Noelle's Familiar
Spirit magic is rare and considered a blessing. When a mage is chosen, it signifies the powerful magical potential they possess. Thus far, the wind spirit Sylph has teamed up with Yuno, and the fire spirit Salamander has found its way to Fuegoleon, the captain of the Crimson Lions.
Noelle's character development is aligned with Asta's and therefore, similar to Yuno's as well. With her potential as a water mage and power trajectory, it's not out of the realm of possibility that Undine, the water spirit, will find itself supporting Noelle in the future.
6 Asta & Yuno Take Over The Roles Of King & Wizard King
Asta and Yuno both have the goal of becoming the wizard king, but only one of them can succeed the title. In light of this, there's the possibility that Yuno becomes the wizard king due to the strength of his magical powers and cold, stoic resilience.
On the other hand, Asta wields impressive strength and the power of a devil. He harnesses those powers for good and is able to connect with people regardless of their social class. This way, Asta and Yuno will both be in positions of power to help make Clover Kingdom a better place.
5 Without Magic, Asta Can Avoid The Corruption Of His Grimoire
Asta's lack of magic power, and his staunch belief in never giving up, are the true source of his powers. This theory indicates that a devil relies on magic in order to manipulate the heart of the five-leaf clover grimoire's owner.
Because Asta possesses no mana, he's immune to the devil's corruption in the same sense that he's able to cut through the magic of other mages. This sets Asta up to potentially utilize his grimoire in ways that even a devil couldn't expect.
4 Did Licita Really Die, Or...?
Asta's backstory is revealed, and his mother, Licita, turns out to be just as strong-willed as he is. She absorbs the mana around her, thus draining her lifeforce as well. With regret, she ends up leaving her son in the care of the Hage church.
Despite this, she ends up raising Liebe, a devil. Licita is forced to confront a powerful foe, and her altercation results in Liebe dwelling within the five-leafed grimoire. While the skirmish indicates a terrible ending for Licita, it's not confirmed that she died. Is it possible that she lives on? It's a wild fan theory with no concrete answer.
3 Nozel Silva X Dorothy Unsworth: More Than Co-Captains!?
Although subtle, there exist a few hints that captains Nozel and Unsworth are involved with each other. When talking with Noelle, Dorothy conjures up a version of Nozel in her glamour world that illustrates a personality unlike that of his stand-offish, sullen vibe.
This indicates that Dorothy may see a side of him that only he allows her to see due to his preference for her. Another hint is that Dorothy knows the history behind Noelle's mother's curse. With insider information that is not widely known, it's possible that Dorothy learned this through Nozel himself. Both hints combine and lead to theories that try to speculate on the nature of Nozel and Dorothy's relationship.
2 Death To Beloved Magic Knight Captains Yami & Vangeance
Captured by the dark triad, Yami and Vangeance are being held as sacrifices in order to restore the Tree of Qliphoth, a channel that connects to the underworld. Their deaths would act as the final objective for the dark triad to create this pathway once again.
While tragic, their deaths would also act as a point of growth for both Asta and Yuno, since it's possible that the two of them would be considered for the roles of captain within their respective squads.
1 Yuno Will Become The Spade Kingdom's King
Yuno's backstory has come to light: he's the crown prince of the Spade Kingdom. Although his goal is to become the wizard king, Yuno's trajectory may change due to learning his connection to the House of Grinberryall.
With Sylph and the spirit dive, Yuno's royalty is foreshadowed due to the crown, cape, and halberd he wields. It's also possible that Yuno will feel the press of responsibility, especially if the dark triad is defeated and the citizens need guidance to rebuild their Kingdom back to its former glory.
