10 He Was Abandoned As a Baby
Asta and Yuno were both abandoned as babies on the steps of the church in Hage. Since he was abandoned at such a young age, Asta grows up with no knowledge about the identities of his parents. While he comes to think of Yuno and the other orphans as his true family he faces ridicule and shame for being raised as an orphan. When Asta is at the ceremony here he and Yuno are set to receive their grimoires he is publically shamed for his low-born status as well as his lack of magic. Asta's status as an orphan is one that he learns to wear as a badge of honor, but in the early stages of his journey, it causes him frequent emotional stress.
9 He Has No Magic
The world of Black Clover is governed by magic, with those wielding the most powerful magic earning the title of Nobles and claiming prestige and fortune. It is therefore understandable that Asta's complete lack of magic would cause him to doubt himself and his capabilities
From the very first episode, it was apparent that Asta's inability to wield magic was his single greatest cause of distress. As a child, he believed that he would one day be able to use magic, even if he could not use it as effectively as Yuno. While he eventually earned his own grimoire and is immensely strong physically, he still yearns to be able to wield magic like everyone else.
8 He Grew Up With No Friends
Asta has always struggled to make friends. From the time he was an orphan other people mocked him for his obnoxious personality, low-born status, and lack of magic. While the other orphans could be kind to him at times they all took it in turns to poke fun at his dreams and lack of ability. As a child, Asta frequently spent time alone training in the forests to increase his physical strength and stamina, and as a result, missed out on many opportunities to just be a kid. Yuno, who Asta admits is his best friend, is also his chief if not his strongest rival, and as such their relationship is fraught with an underlying tension.
7 No One Takes Him Seriously
From a young age, Asta learned to overcompensate for his lowly status and lack of magic by working hard and never backing down from a challenge, even one that he would obviously lose. His work ethic and self-doubt led him to become single-minded to the point of obsession and to disregard the opinions and criticisms of others. Despite his hard work, no one takes him seriously due to his lack of magic. When Asta conveyed his goal of becoming the Magic Emperor during the Magic Knights entrance exam the other examinees ridiculed him. Even Sister Lily and Father Orsi frequently downplayed his ambitions, and rarely offered him any real encouragement as he worked toward his dream.
6 He Annoys Everyone Around Him
While Asta is usually cheerful he is also rather loud and obnoxious. These personality traits have led to those around him constantly shouting at him to shut up, particularly his teammate, Noelle, and the captain of the Black Bulls, Yami Sukehiro. To protect himself from ridicule, Asta developed a sense of sarcasm and is able to laugh at himself, yet even when he is just being himself he is frequently rebuked by enemies and friends alike. He is loud and obnoxious because he is constantly fighting with his own inner demons as he struggles to prove himself, but it takes time for others to understand this about him and leads to him frequently earning their ire.
5 He Has To Struggle For Everything
Nothing comes easily for Asta. Unlike Yuno, who is good at everything he does, Asta has to work extremely hard to achieve even a minor amount of success. Asta puts in hours of grueling work to develop his body but is never able to defeat Yuno in a duel. Captain Yami frequently requires Asta to prove himself in a series of increasingly difficult challenges. Even in victory, Asta often suffers greatly, such as when he defeated Vetto only to lose the use of his arms. He struggles to gain acceptance as a Magic Knight who cannot use magic, and despite his accomplishments, he still does not earn the same amount of respect as less powerful knights.
4 He Is Hopeless When It Comes To Love
Since he was a kid, Asta has been in love with Sister Lily, the nun assigned to the church in Hage. He doesn't hesitate to proclaim his undying devotion to her despite her status as a nun making their union highly unlikely. Yet, Sister Lily is pestered by his advances and often pummels him into the ground with her Water Creation Magic: Holy Fist of Love.
Yuno says it bests when he tells Asta is "short, loud, obnoxious, and immature, which are all traits that women find unattractive." Meanwhile, Mimosa and Noelle, who are both infatuated with Asta, wait silently in the wings, but Asta is completely clueless about their desires.
3 He Never Got To Meet His Mother
Asta's mother, Licita, was a mage whose power allowed her to passively absorb the magic and lifeforce from other people and creatures. Due to her inability to control this power, Licita abandoned Asta when he was an infant. Ironically, this proved to be a futile gesture, as Asta was born with no magic. Unfortunately, Asta never gets the chance to reunite with his mother, as she dies tragically saving the devil Liebe from Lucifero. Her sacrifice is the reason why Asta inherits the five-leaf grimoire and is possessed by Liebe, and in this way, she lives on through Asta and Liebe.
2 His Father's Identity Is Still Unknown
While the identity of Asta's mother, Licita, is eventually revealed through his contact with the devil, Liebe, the identity of his father remains a mystery. Fan theories abound as to who Asta's father might be, from the Magic Scholar, Morris, to the Dark Triad member, Dante Zogratis. Some fans have even gone so far as to suggest more sinister origins of Asta's lineage, speculating that Asta's father may be a devil. The truth behind the identity of Asta's father is one of the last great reveals yet to occur in Black Clover, and no matter how it plays out, given Asta's luck, fans may shed more than a few tears when and if Asta's father makes his presence known.
1 He Pursues His Goals To The Detriment Of His Health
From the first episode, everyone in Asta's close circle has told him to give up on his dream. Despite the odds stacked against him, Asta continues to push himself to get stronger. While perseverance is an admirable trait, Asta's obsession with becoming the Wizard King often puts his body and mind in harm's way. When he loses the use of his arms he slips into a depressed mood. He convinces himself that he will never be depressed again, but that is easier said than done. His mood oscillates between cheery and gloomy, and his short temper often belies his deep feelings of insecurity. One of the few things that keep Asta going is his desire to surpass Yuno, and it is a safe bet that without their rivalry he would have given up long ago.
