History
2,000 years ago, Anos created the Seven Elder Demon Emperors from his own blood. After Anos's sacrifice, the Seven Elder Demon Emperors co-operated with the Hero Kanon to create the fictional Demon King Avos Dilhevia as a scapegoat for the human's revenge in Anos' place. Kanon then fused six of his roots with 6 out of the 7 demon elder emperors, including Medoin, and erased their memories so that if they came in contact with Anos when he had reincarnated, he will not know about Kanon's plan because they couldn't lie to him.

Hero Academy Arc
During the academy exchange with Hero Academy, the remaining Seven Elder Demon Emperors disappeared from Dilhaide and were sighted entering the human royal capital Gairadite. Though at first they were hiding, Medoin Garsa, Zoro Angart, and Eldora finally made their move by attacking the temple holding the legendary holy sword of the Hero Kanon. By the time Anos arrived, the trio have already succeeded, as Avos Dilhevia was able to draw out Evansmana. The ensuring confrontation between Anos and Avos doesn't last long, and Avos leaves with the trio to broadcast a declaration of war all over Dilhaide against the human kingdom.
