Orthos

Orthos (オルトス) was the true king of the Kingdom of Filtwood. He was a Demon who was thought to be sealed away by a champion named Orthos, but that story was either entirely fabricated, or the demon managed to kill, and later impersonate the champion.

Appearance
Orthos was shown to physically appear as a human male with blond hair. Upon revealing himself as a Demon, he grew curved goat like horns and his eyes becoming glowing red, signifying himself as a descendant of the Primordial, Rouge.

Background
Orthos was one of the few cases of self-naming. As a man-made hero, the voices of his nation's people gave him power, that power gave him a name allowing him to become a named being on his own, allowing him to evolve from a Greater Demon to an Arch Demon.

Story
One day, he tried to trick and kill adventurers, including Shizue Izawa, in order to gain more power, but instead got his Soul devoured by Primordial Noir, killing him completely with no chance of resurrection.

It is revealed by Noir that Orthos is part of the Demon color line of Demon Lord Guy Crimson.

Relationships

 * Shizue Izawa: Orthos merely saw Shizue as someone to gain more power from.
 * Noir: Orthos, at first, thought of Noir merely as a weak Demon who he could easily kill; however, after seeing that he was massively outmatched, his face briefly flickers with fear before Noir kills him.
