The Misfit of Demon King Academy

Arriving in Giorhaze, capital of the Underground World Giordal, Anos follows a wary Erdomaid to a church. There, they obtain a Pledge Jewel which summons dragons. Furthermore, Erdomaid sees Naya’s aptitude and makes a pack with her after learning her plan. Anos hears about Ahide’s actions from the bishop of the church and decides to catch him before he meets the pope.

That day, Anos had a dream about a time that he lived together with a young girl. The young girl is strangely also named Arcana…. Furthermore, the fact that the Draconids called the fusion of Sasha and Misha the Goddess of Absurdity, Genedonov, was also a problem. To investigate the piling mysteries, Anos decides to take a special class in the Underground World. And as a special lecturer, Anos teaches the student of Demon King Academy himself!?

Ahide announces that Midhaze will be destroyed. However, the oracle’s will contradicts Arcana’s true intentions. Shin also joins in the fray as the two finally face off! Ahide possesses Arcana and thrusts the judgement of the Sword of the Almighty, Leviangilma, upon Anos. Arcana states that to destroy Ahide, he must be slashed three times with the Divine Sword. But the sword obliterates the source of anyone who draws the sword from its sheath….

A horde of dragons approaches Azeshion! To protect their homeland with their own hands, the Hero Academy students set out to slay the dragons without the help of Anos and his friends. Under Emilia’s command, the Hero Academy students engage in a battle to the death. Meanwhile, Lay and Misa wind up in a predicament after being captured by Lysius…. Anos and the others head to the Underground World to take care of their own agenda. There, he learns that Ahide is controlling the Draconids.

Emilia and her students take on the dragon-slaying and binding spell called “De Jelias.” However, Emilia and her students failed because they couldn't corporate with Laos and others. It was then that she caught a glimpse of their helplessness…. Meanwhile, Ley who was invited as a hero, has an audience with Lysius, King of Gairadite. He is asked to save the ailing royal family. But as he is shown around, what he encounters is…!

Erdomaid trains the students in methods of dragon slaying. He does so in a dangerous battle with an actual dragon summoned. Anos and his friends infiltrate the dragon’s den and arrive in the Underground World, where the dragonfolk called Draconids live. Ahide, who attacked the previous evening, guides them to the Institute of the Gods, Everastanzetta. There, Anos is told how he has already been involved in the “Judgement Selection.”

To investigate the dragon sighted in Azeshion, Anos and his friends visit the Hero Academy in the name of participating in an exchange program. Emilia teaches at the Hero Academy, but despite her efforts, Ledriano and the other students of the Hero Academy are rather unenthusiastic about the exchange. Furthermore, Zamira, the headmaster of the Hero Academy, issues a decree to slay the dragon. Yet, as Emilia resists his unreasonable order, the Hero Academy students begin to lose interest…

The Mythical Age. In an effort to destroy the Moon of Creation, Anos meets the Goddess of Creation Militia and begins to interact with her. And now the present... Anos, who has made his identity as the Demon King of Tyranny known throughout the world, joins classes at Demon King Academy as the transfer student, Anoshu. To train even stronger demons, Erdomaid instates the Great Demon King Drills. As the first initiative, swordsmanship training under Shin begins!

Avos Dilhevia takes control over Magic Sword of Destruction Venuzdnor at last. Anos gives a calm smile to the enemy who seizes everything from the Demon King of Tyranny and reigns control, however... The true purpose of Avos taking control over the Magic Sword at the end of the fierce battle is revealed. How does Anos face off against the Child of God, destroyer of the Demon King of Tyranny, and the power that destroys all life!?

Lay challenges Avos to liberate Misa whom he loves. However, Heavenly Father God NousGalia aids Avos, and seals Lay’s power of Evansmana. There, Anos and Shin arrive. Shin fights NousGalia once again to avenge his late wife, but he struggles against the enormous power of God. Then, he hears a voice for the first time in two thousand years...

After witnessing Great Spirit Leno and Shin meet a tragic fate, Anos and his classmates return to Delsgade in the present day. There, persecution against those of mixed blood by Meleheyth and the demons whom Avos Deilhevia brainwashed was progressing. Anos holds them off and heads to the throne room. He faces off against Avos who attempts to steal Magic Sword of Destruction Venuzdnor!

To prevent a clash that may happen between Anos and humans 2,000 years in the future, Hero Kanon proceeds with the plan to become an imposter Demon King himself, with Shin agreeing to this decision. Gradually but surely, Shin begins to change, and Leno realizes that she loves him. However, after fulfilling his duty to protect her, Shin begins to leave her side...

Anos and the others continue their investigation in Aharthern. Although he wasn’t able to switch his source as Avos Dilhevia as the Demon King of Tyranny, Anos receives an important hint from Leno. Lay engages in practicing swordsmanship with Shin. After this, Anos follows after Erdomaid to Delsgade. There, they encounter Demons who were ruling over humans.

The Forest of the Great Spirit Aharthern. Anos who has transformed into his younger form, takes on the fake name Anoshu Polticoal, and decides to stay to investigate for a while. They watch over Shin who was tasked with being a bodyguard of the Great Spirit Leno by Anos prior to his reincarnation, and then appears the Blaze Death King Erdomaid, who claims to have brought information regarding the gods...

Anos and the others have infiltrated the Underground Dungeon. Before their duel against Avos Dilheiva, they use Time Magic, Revalon, to go back in time to Gairadite two-thousand years ago, in order to unravel the secret behind Misa’s birth, Shin Reglia, Anos’ right-hand man’s, intentions, and the reason behind the Great Spirit Leno’s death. What Anos saw in the world after he had passed was―.

Avos Dilhevia who appeared in Delsgade was actually Misa, who was being controlled by traditions and rumors. After getting the demons in central Dilhade on her side, she declares that she will destroy Anos. Anos is making his way to the Demon King’s Castle to rescue Misa. Meanwhile, in the city, the people being controlled by Avos were attacking mixed blood demons, and they had even started making their way to Anos’ parents…

In order to visit the Spirit King, Anos and his team continue to go through trials provided by the Great Tree Spirit Enyunien. The next trial, “The staircase of Geunier” is a trial where they must choose the 5 correct paths out of the 20 paths before them, which appears to be a game entirely dependent on luck. However, thanks to the advice from Lena, Anos and the team individually made their ways to the top. Lay and Misa arrive to the Spirit King’s castle first, and engage in the final trial!

Anos and the first-year students visit Zehenburg under the guise of an expeditionary examination. Anos's goal is to find his former right-hand man, Shin Reglia, who left a message for him, "Wait for me in the Spirit Forest Aharthern." On the way to the forest, Anos meets an information broker, Lena. Together with her, who is also heading to Aharthern, the group proceeds into the forest's depths.

Anos and his classmates search around Demon King Academy for the “Child of God.” While Anos’ comrades are fending off the attacks from the demons of two thousand years ago, Anos himself faces the King of Death’s Army Officer, Ziek Ozma, in a duel of intellect. In this duel, Anos must speculate who the “Child of God” is and make the correct guess. However, the number of times he can make his guess is limited. What was Anos’ answer, and what is Ziek’s motive ― ?!

Erdomaid DittiJohn, one of the four evil royals, has appeared before Anos as a teacher at Demon King Academy. Not only that, he claims himself to be the Heavenly Father God NousGalia, and that the new "Child of God" who will vanquish the Demon King of Tyranny is also at the Demon King Academy. The “Misfit” who overcomes all odds sets off to a new battle!
