Asta and Yuno were abandoned together at the same church, and have been inseparable since. As children, they promised that they would compete against each other to see who would become the next Emperor Magus. However, as they grew up, some differences between them became plain. Yuno was a genius with magic, with amazing power and control, while Asta could not use magic at all, and tried to make up for his lack by training physically. When they received their Grimoires at age 15, Yuno got a spectacular book with a four-leaf clover (most people receive a three-leaf-clover), while Asta received nothing at all. However, when Yuno was threatened, the truth about Asta's power was revealed, he received a five-leaf clover Grimoire, a "black clover"! Now the two friends are heading out in the world, both seeking the same goal!
Asta et Yuno were orphaned boys who grew up together, but one was more fortunate than the other when it came to magic. When the day comes to receive their magical books, a grimoire, Yuno receives an extremely rare one while Asta does not receive one at all...
The grimoire that Yuno received was a legendary grimoire with a four-leaf clover. A bandit named Revchi comes to steal it, and Asta comes to Yuno's rescue.
Asta and Yuno spend six months training for the upcoming Magic Knights Entrance Exam. Everyone seems to think Yuno is sure to pass, but worries that Asta is just wasting his time.
Asta and Yuno head toward the colosseum in the royal capital for the Magic Knights Entrance Exam, while looking around and admiring all the things they’ve never seen before.
The entrance exam finally comes to a close. The time has arrives for the captains to decide which candidates they want to join their squads.
Asta has arrived at the home of the Black Bulls, which Yami himself called the absolute worst Magic Knights Squad. He is greeted by the squad's unique members.
As a new member of the Black Bulls, Asta is thrilled to receive his very first private room, even though it's tiny. Everything Asta sees as Magna shows him around the squad's base is new and exciting to him.
The Magic Knights: heroes that everyone in the kingdom looks up to and dreams of becoming one day. But the new recruit, Asta, has yet to do anything that seems like what a Magic Knight should be doing, as he’s stuck doing random chores.
On Yami’s orders, Asta and Noelle go on their first mission with Magna to hunt wild boars. They successfully complete the mission and go to Saussy Village to meet with the mayor, Seyhe.
Asta, Noelle, and Magna are doing their best to protect the villagers of Rayaka from the ice magic user Heath and his underlings, but Asta’s attacks don’t seem to be working, and Magna’s magical powers are running low.
After Asta, Magna, and Noelle saved the villagers of Saussy Village, the Wizard King gives the Black Bulls a star of honor. Asta and Noelle also receive their first pay as Magic Knights, and Asta is filled with happiness.
As they were visiting the Black Market, Asta and the others see an old woman get robbed, and Asta goes after the thief.
While on an escort mission, Yuno, Klaus and Mimosa are attacked by a mysterious group of men. Klaus senses that they’re in danger and wants to escort Salim as quickly as possible, but Salim insists on visiting Yuno’s hometown, Hage Village.
A dungeon appeared near the border of the Clover Kingdom and the Diamond Kingdom. The dungeon is like an ancient ruin. It may contain important treasures, but they're guarded by various magical traps.
Yuno, Klaus, and Mimosa from the Golden Dawn appear in front of Asta and Noelle, apparently sent on the same mission. Klaus mocks the Black Bulls for their awful reputation and gets in an argument with Asta.
Yuno, Mimosa, and Klaus get close to the treasure chamber in the dungeon. However, a mage from the Diamond Kingdom named Mars gets in their way.
In order to go to the treasure chamber together with his friends, Yuno confronts Mars alongside Klaus, so that the injured Mimosa can heal herself. But they have a hard time harming Mars at all.
Asta, Yuno and the others finally get to the treasure chamber, and they’re in awe at the mountain of treasure in front t of them. Yuno finds a strange scroll with strange writing, and then his grimoire does something strange...
Asta is gravely injured in the battle against Mars and collapses. Despite his own injuries, something drives Mars onward, and he tries to finish off Asta.
Asta and Noelle head to the Magic Knights Headquarters in the Noble Realm to report on their mission to capture the dungeon. On their way, they run into Yuno, Klaus, and Mimosa, and they all head to the headquarters together.
Asta defends Noelle from her siblings at the decoration ceremony, and the other nobles try to put him in his place. Meanwhile, Leopold and Fuegoleon seem to have taken a liking to Asta, which causes an argument between Fuegoleon and Nozel.
After hearing about the attack on the capital, Asta rushed out, and the rest of the Magic Knights quickly followed. They found that corpses being controlled by Rades’s wraith magic were attacking the citizens.
Thanks to Noelle’s help, Asta is now able to concentrate on the battle. However, because of the attack he took earlier, Asta continues to lose stamina and isn’t able to move as well as he’d like.
While the masses were praising the Magic Knights for saving them, most of the Magic Knights present are swallowed up by a spatial magic spell known as Blackout.
Captain Fuegoleon is swallowed up by spatial magic right in front of Asta and the others. Noelle realizes that the spellcaster must be nearby, since the spell pinpointed Fuegoleon. Asta finds the spellcaster, but something unbelievable happens next.
More enemies appear before Asta and the others. Despite being badly wounded, Asta and Leopold haven't lost their fighting spirit, and they charge at the new enemies. The enemies realize how dangerous they are and try to kill them immediately.
The one who saved Asta from the group calling themselves the Eye of the Midnight Sun was the Wizard King, Julius, who was waiting for them at their base. Asta and the members of the Eye of the Midnight Sun are in awe of Julius's power.
Finral invites Asta and Luck to go to a mixer with him. Noelle hears about this and ends up following them because she’s concerned about Asta. To deepen her cover, she even gets a job at the pub they go to.
Months have passed since Asta and Yuno became Magic Knights and took their first steps toward becoming the Wizard King. Father and Sister Lily couldn’t be happier about all of their hard work.
The Black Bulls get a day off after getting paid, and Gauche goes to visit his beloved little sister Marie. To his surprise, he finds Asta already there and playing with her.
Asta, Theresa and Gauche follow a faint mana trail in pursuit of the abducted children.
Upon finding the kidnapped children drained of their magic, Asta and Gauche attempt to deliver justice upon Baro and Neige.
The threat to the children grows when Asta and Sally face a giant mud monster; Gauche grabs his young sister and makes a break for it, but she pleads with him to return and help the others.
Licht, the leader of the Eye of the Midnight Sun, arrives in the cave to finish what Sally and Baro started; Asta struggles to keep up with Licht's rapid attacks.
Licht criticises the Clover Kingdom's hypocrisies of respecting magical ability yet forces those with powerful magic to suffer in poor living conditions, continuing his fight with Yami while Asta faces Valtos.
While the children safely return home, Yami, Asta and Gauche confront a trio of new enemies.
Magic knights Jack, Charlotte and Nozel arrive to assist Asta and Yami against the Third Eye.
Asta must report to the king on his battle with the Eye of the Midnight Sun and Yami accompanies him to the capital to attend a conference with the Magic Knight captains.
The traitor is Gueldre Poizot the captain of the Purple Orca squad, despite his attempts to denounce it before the other Magic Knight captains point out that the rumors of his criminal dealings while advising him to let Marx probe his mind if he has nothing to hide.
Yuno, Klaus and Mimosa hear a scream and rush into the shop it came from, only to find it was Noelle being stripped naked by Vanessa so she can try on bikinis.
While training, Asta and Noelle meet Kahono, a wannabe idol who plans to entertain with a combination of music, dancing and magic.
The Black Bulls make a harrowing journey to the Underwater Temple and meet its people.
The temple mages attempt to divide and conquer when Gifso magically separates the Black Bulls into different parts of the Underwater Temple to fight one-on-one battles.
One of the members of the Third Eye, Vetto, appears at the Underwater Temple along with his underlings.
Magna, Luck, and Gio, the most powerful Underwater Temple mage, risk their lives fighting Vetto. Asta and Kahono’s older brother, Kiato, also arrive at the scene.
Kahono and Noelle reach Asta and the others. Noelle is astonished at how powerful Vetto is, but Kahono remains confident. She is the granddaughter of Gifso and cherishes everyone at the Underwater Temple, which she is willing to do anything to protect.
Despite being greatly injured in the battle against Vetto, Asta stands up to face him again. Seeing this, Vanessa and Finral come to assist Asta, too.
Asta continues his attacks against Vetto with support from Vanessa and Finral. They finally manage to land a blow on Vetto, but it’s not very effective. Vanessa and Finral remember when they were younger and much weaker.
Asta’s sword finally manages to take down Vetto! But that was all a part of Vetto’s plan. He manages to steal Asta’s sword and break his arm. Vetto proudly proclaims victory, but Asta doesn’t give up

After Kiten is successfully protected Yami introduces Asta to a recovery mage named Owen that works directly under the Wizard King so he can get his arms healed. Owen is known as the most powerful recovery mage in the Clover Kingdom, but Asta's arms were in a horrific condition. Finral happens to walk by the room when Owen tells Asta something about his injury, and then he tells the rest of the Black Bulls, who are shocked. The Black Bulls go to check on Asta and see that he's still not discouraged at the bad news, and they all come to a decision...
