Eldmed Ditigeon

"At the end of a line lies the unknown."

- Eldmed to Class 1-2

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 was described as a tall man with delicate features, long purple hair, and a well-built physique.

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 Portikoro and most of the time carries a twisted smile.

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, the majority of the class met him with skepticism, 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 true and should he lie, his life will 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 still play their role 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 and the world they create, and which one came first. He goes along with Sasha's answer of the creator being first, but if so, how were they born? 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. }}

Anos Voldigoad
Eldmed has a great deal of respect and obsession for Anos.

Naya
One of Eldmed's students. He likes to tease her with nicknames.

Shin Reglia
Eldmed sees Shin as a powerful individual, who is worthy of serving as the Demon King's right hand, and respects him.
