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 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, Yuno and the others finally get to the treasure chamber, and they’re in awe at the mountain of treasure in front of them. Yuno finds a strange scroll with strange writing, and then his grimoire does something strange...

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.

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.

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.

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.

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.

As they were visiting the Black Market, Asta and the others see an old woman get robbed, and Asta goes after the thief.

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.

Asta and Yuno get back to their village after an elf had attacked it. They were heading to the royal capital along with Captain Nozel and Noelle, but they saw that their village was in trouble and were given permission to make a detour. In order to protect the villagers, Asta and Yuno face off with the elf. The father that had raised them was able to see how much Asta and Yuno had grown, but...

Despite being affected by the reincarnation spell, Yuno was able to regain his consciousness. Asta and Yuno then fight the leader of the elves, Licht. Licht then uses one of Asta’s swords and attacks them both. Asta and Yuno are pushed to the edge but they manage to fight back. Meanwhile, another reincarnated elf shows up in Asta and Yuno’s home village of Hage and attacks the villagers.

Asta was taken deep back into the labyrinth by Raia, who had suddenly appeared. There, he found not only Mimosa, but Klaus, Hamon, and Yuno who had reincarnated as elves. Klaus and Hamon have completely different personalities and they attack Asta. However, Yuno doesn’t join the fight yet one way or another. Asta doesn’t want to fight his friends and says that he’s going to survive and become the Wizard King. That somehow brings out a change in Yuno. Meanwhile, there was someone else watching the battle quietly: Another Licht that looked just like “the leader of the Eye of the Midnight Sun Licht.” Apparently, he is the real Licht, the leader of the elves.

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.

In this world, everyone can use magic... and in a land called the Clover Kingdom, two young men, Asta and Yuno, strive to become the Wizard King, the greatest of all magic users. Asta and Yuno were abandoned together at a church in Hage, a village in the boonies, and lived as brothers from that day onward. For some reason, however, Asta never developed the ability to use magic, even when Yuno had already mastered wind magic. Now, at last, the boys are turning fifteen, the age at which children receive their own grimoires. Asta has high hopes that receiving his grimoire will awaken his latent ability to use magic, but when the time comes...

Emilia tried to warn the villagers of Arlam that danger was coming and they should evacuate, but was not well-received. As she's pondering what more she can do, Wilhelm arrives at the mansion with a message... Subaru and Julius face off against Betelgeuse's Unseen Hand. However, as one Unseen Hand after another is launched their way, the two heroes find themselves completely on the defensive.

The half of the mercenary army that had been blocking the road during the White Whale subjugation returns to join the main force. Subaru then leads the way into the forest of the Mathers domain, hoping to find and destroy the Witch's Cult before they can learn of the subjugating army's movements. Subaru and his companions head toward Roswaal's mansion to evacuate Emilia and all the others there, stopping at the nearby village on the way and beginning to evacuate its residents as well. However, the situation takes a turn that nobody expected...

Subaru has devoted everything he had, and done all he could do. His passion has captured Crusch's heart, as well as Anastasia's cooperation, and they all enter into the battle against the White Whale together. Subaru and Rem lose all words at the sight unfolding above them. Just when it seemed they would soon have the White Whale cornered, despite the sacrifices it took to reach that point, the battle takes a turn that no one expected.

Botaro has his own ideas about what to do with the gold.

The chaotic battle at the Sapporo Beer factory begins.
