Shortly after Anos’ encounter with Misha and Sasha as well as his battle with Ivis, a transfer student named Ray enters the Demon Academy. As the Master of Magic Sword and powerful enough to defeat the Seven Elder Demon Emperors, Ray makes it clear that he wants to join a team with a capable leader, and requests to join Anos’ team. However, Anos refuses and proposes to Ray that, "If you prove that you are worthy, I will allow you to become one of my followers." Ray decides to form his own team and battles head-to-head with Team Anos during the team competition exam.

In recognition of their accomplishments in the team competition exam, Anos welcomes Lay and Misa to his team. The team gathers at Anos’ home to celebrate, but shortly after, Lay and Anos are announced as participants in the Magic Sword Tournament. Lay rejoices at the chance for a rematch with Anos, but Anos suspects that there is an ulterior motive. The situation escalates when Misa takes Anos to meet one of the Seven Elder Demon Emperors, Melheis Boran.

Anos resolves to defeat the Royalists no matter what tricks they have up their sleeve. He uses the sword received from his father Gusta to fight in his first match in the Magic Sword Tournament. Meanwhile in the dressing room, Lay clutches his chest. Sensing that something is wrong with Lay, Anos speculates that somebody is controlling Lay and a hostage may be involved. Who is conspiring to control the Magic Sword Tournament from behind the scenes?

Anos and Lay battle head-to-head at the Dilhade Magic Sword Tournament finals. With Sheila being taken hostage, the two are unable to fight at their full potential and come to a decision. Just as the showdown reaches its climax, a huge Magic Circle appears in the arena. The scenery around Anos and Lay begins to distort, and they are taken into an alternate dimension. The mastermind behind the recent events finally reveals his true identity.

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 ― ?!

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―.

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...

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...

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…
