Devidra

Devidra (デビドラ) is a demon from two thousand years ago. His present life is Nihid (ニヒド), a teacher of the Demon King Academy.

Appearance
Devidra has white hair and pointy ears. His skin is reddish, and he wears black armor.

Personality
Devidra developed an intense hatred towards humans due to the Hero Jerga murdering his child in cold blood. Consumed by his hatred, Devidra committed the same crime he had loathed Jerga for and even disobeyed the Demon King's orders. He could not live peacefully, knowing that the humans who slaughtered their brethren were living freely on the other side of the wall.

History
Shortly after the war ended, Devidra discovered Igareth Ijeiska attempting to enter Delsgade, so he brought the human prince to the Arena for a public execution despite the Demon King's prior order to release him. In the original timeline, he killed Igareth but would've eventually come to regret his actions, causing him to reincarnate to avoid repeating the same mistake and leave his hatred behind.

Two thousand years later, in the Magical Age, Devidra reincarnated as Nihid and became a teacher at the Demon King Academy.

Abilities

 * Great Magic Power: As a demon from the Mythical Age and one of Anos' top subordinates, Devidra possesses a large amount of magical power.

Anos Voldigoad
Like most demons of the Mythical Age, Devidra held nothing but unquestionable love and loyalty towards his master, Demon King Anos.

Igareth Ijeiska
As a relative of Jerga, Devidra saw Igareth as a target of revenge. Even though the boy did nothing wrong, Devidra viciously attacked him and eventually killed him. It was this sin, that motivated him to reincarnate into the Magical Age.

Upon reuniting with the reincarnated Igareth, the two worked together alongside other reincarnated followers of the Demon King to defeat the Seven Demon Elders and rescue the hybrid students who were taken hostage.
