Melheis Boran

Melheis Boran (メルヘイス・ボラン, Meruheisu Boran) is one of the Seven Elder Demon Emperors created by Anos Voldigoad.

History
2,000 years ago, Anos created the Seven Elder Demon Emperors from his own blood, among them was Melheis. After Anos's sacrifice, the Seven Elder Demon Emperors co-operated with Kanon to create the fictional Demon King Avos Dilhevia as a decoy to protect Anos when he reincarnated. Kanon then fused six of his roots with 6 out of the 7 demon elder emperors, excluding Melheis, 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.

When Melheis regained consciousness, he found himself in the Great Spirit Forest Aharthern with no memories of how he got there, thinking he ended up there trying to escape from whoever erased his memory. Sometime after returning to Dilhaide, Melheis began supporting the unification faction.

Plot
After Misa Ilioroagu brought the reincarnated Anos to Melheis, he fell down to his knees and shed tears, recognizing his former master through his demon eyes. But with Melheis's memories erased, Anos wasn't able to learn much about Avos Dilhevia or the revised history.
