Eldmed Ditigeon

"Exactly! That is his flaw! The Demon King of Tyranny has no flaws. He is so flawless that he has no enemies. Demon King Anos needs enemies if he is to become a stronger Demon King—the true Demon King!"

- Eldmed to Shin Reglia in "The Conflagration King's Proposition"

Eldmed Ditigeon (エールドメード ディティジョン) is a great demon who reigned during the Mythical Age as the Conflagration King (熾死王). He is the homeroom teacher of Anos' class and one of the Four Evil Kings, but his body gets possessed by Nosgalia.

Appearance
Eldmed is a tall and slender man with purple eyes and hair who wears a long trench coat and a top hat. He also carries a long cane.

Personality
He is a rather bold and cocky man who looks down on his enemies, but praises those who are worth praising, as he did with Anosh Polticoal, and most of the time, carries a twisted smile.

History
During the Mythical Age, Eldmed became prominent as one of the most powerful demons of the era, gaining renown as one of the Four Evil Kings, the strongest king-class demons of the era. He battled for control over Dilhade and to assert himself as the ruler of the demon realm, as he battled other demons for that right. Eventually, he crossed paths with the Demon King Anos, who battled him and defeated him. Eldmed became fascinated and obsessed with Anos, as he wished to see the limits that Anos could reach and transcend, battling him numerous times in order to gauge his strength. After that he set about to create powerful opponents for him, as he evaluated various powerful human warriors but found that only Hero Kanon could pass his selection, and even he wasn't a match for the Demon King.

During the Great War, his territory would be invaded and occupied by humans, as he and his followers relocated to Delsgade.

Following the Hero Kanon's plan, Anos' loyal subjects and even the powerful demons who didn't get along with him moved away from Dilhade.

Great Spirit Arc
After the war with Azesion was averted, the Demon King Academy reopened, and Eldmed was introduced to the students of Class 1-2 as their new teacher. When he announced that Anos was the true Demon King of Tyranny, most of the class met him skeptically, particularly the royals, whose emotions varied from anger to laughter. Eldmed then showed them a Zekt contract signed by many important figures in Dilhade, including the Seven Elder Demon Emperors, stating that Eldmed's words were valid and should he lie, his life would be forfeited.

He asks Anos to stand in front of the podium while he makes all the chairs and desks in the classroom disappear, stating that their behavior was intolerable. The Anos Fan Union knelt immediately and so does the people close to Anos. To those who were still standing, Eldmed demanded why their heads were still raised high in the presence of a king and if they were willing to commit treason. He then told them that royalty wasn't anything special and that they were replaceable, that there wasn't anything more ridiculous than to play their role still when the play was over. After everything was over, Anos passed Eldmed and told him that his disguise was very poor, Nosgalia.

Silver Water Holy Sea Arc
After the world's reincarnation, Eldmed teaches Class 1-2 about the new world. He explains that the world was recreated identically to prevent new conflicts, but that didn't mean it was the same. Order was changed, and the world no longer leaned toward destruction. The topic eventually moves to creator gods, the world they create, and which came first. He goes along with Sasha's answer of the creator being first, but how were they born if so? If there is nothing, nothing happens. That's why Eldmed concludes that order already existed before the god's birth, and if that's the case, then perhaps there was another world outside of their own.}}
