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…

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―.

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 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.

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...

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!

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...
