Ivis Necron

Ivis Necron (アイヴィス・ネクロン, Aivisu Nekuron) is one of the Seven Elder Demon Emperors created by Anos Voldigoad.

Appearance
Ivis looks like a skeletal mage. He wears a robe that covers his entire body and a headpiece with side ornaments, leaving only his skeletal/mummy face to be seen. He doesn't look to have a bottom jaw and speaks through a jaw-mouth ornament on his chest.

Personality
Ivis is quite smart, capable of developing complex fusion magic. He became wary of Anos when he learned that someone can oppose him. When Anos explained who he was, Ivis remained suspicious as he knew what Anos was capable of.

History
2000 years ago, Ivis was created from Anos's own blood, alongside the remaining Seven Elder Demon Emperors. 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 decoy to protect Anos when he reincarnated. Kanon then fused six of his roots with 6 out of the 7 elder demon emperors, including Ivis, 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 Sasha was born, Ivis cast the spell Separation and Fusion Reincarnation  on her in order to create the vessel for the Founder to reincarnate into.

Demon King Academy Arc
Ivis went to Anos's class to teach them some great magic. As he was introduced, Emilia Rudewell told Anos to not be rude and a moment later, Arnos greeted Ivis like an old friend. Ivis wondered who he was and Anos then got closer and tried to use memory restoration magic, but had no effect. He then used origin magic  to turn back time and Ivis was surprised there was time magic and indeed remembered his past, but Anos was not in it. Ivis thanked him for what he did and that he knows that someone who could oppose him now exists. Anos then got back on his seat and Ivis continued the class showing fusion magic. Anos then told him he saw a flaw and as he corrected it, the duration of the spell increased several hundred times more. Ivis couldn't believe someone studied fusion magic before him, but Anos explained it was all his doing and he was just seeing it for the first time, but knew that after a thousand years, Ivis himself would have seen the flaw. Ivis then told Anos there was nothing he can teach him and wondered why he was even in the school.

After class, they spoke and Anos explained someone changed his name and changed his memory. Ivis agreed that may be true, but at the same time, Anos may be the one who done that and he can't fully believe him at the moment, but he will remain neutral towards him for the moment unless he planned to use his talents against the Demon King.

After Anos destroyed the roots of Eugo La Raviaz and an unknown root, he discovered that Ivis' roots were still intact, so he cast  to revive him. Anos then gave Ivis his memories of him, and tasked him with investigating the remaining Seven Elder Demon Emperors in secret.

Demon Sword Tournament Arc
When Anos questioned the reason for his nomination for the Demon Sword Tournament, he called for Ivis in his owl disguise and agreed to meet up at the Cat Cafe "Matatabitei". Once there, Ivis reports back his findings.
