Llega a la academia un nuevo y misterioso estudiante. Parece que tiene algún tipo de relación con el Rey Demonio de la antigüedad.

Anos tiene la posibilidad de participar en un torneo, pero tiene sospechas sobre el organizador y la finalidad de dicho torneo, así que investigará un poco.

Anos se clasifica para la final del torneo sin muchas preocupaciones, pero ese hecho supone una gran molestia para ciertas personas de la élite.

Anos llega a la final del torneo con dos tareas pendientes. La primera es derrotar a Lay, pero la otra será arruinar los planes de sus enemigos.

Anos está extrañado ante la existencia de la Academia del Héroe, así que se presentará allí acompañado de Sasha para ver de qué se trata en realidad

Por fin llegan todos los demás alumnos a tiempo para comenzar con la prueba interescolar.

Tras las presentaciones y los primeros roces entre alumnos de ambas escuelas, es hora de que comience la prueba.

Llega el día en el que se revela el origen del Rey Demonio falso, el plan real de Lay y todo lo que hay tras los últimos dos mil años de guerra entre humanos e infernales

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!

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.

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!

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…

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!?

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.”

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!?

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.
