Demon King

The title of Demon King is used when a Demon becomes the leader of said race and it tends to be passed down within a particular family line. The very first Demon King was also the original demon and the first demon to ever exist, a demon by the name of Omega. Though it's not outright stated, it is implied that the Demon King is almost always related to Dakol in some way. For instance, Omega was essentially Dakol's son and the inheritor of one of the Supreme Ruler's Orbs of Dakol. After the destruction of Equinax, the title seemingly went with it until the time of the Chaos War when a second Demon King finally emerged to battle against the Vampires and their Overlord Haste Battosai. This Demon King was called Kuro Neele and he succeeded in ending the war by sealing Haste away in the chamber of Amelie Bellec (The Lost Guardian) with help from Haste's two sons, Damion Battosai and Arikado Faust. After Kuro sacrificed his life to stop The Path (which failed), the demon race was leaderless once more until an unlikely candiate took up the mantle and preceded to barter a lasting peace treaty between the demons and vampires. This individual who is often hailed as the greatest Demon King was none other Izar Neele, son of Kuro Neele and the Lost Guardian Amelie Bellec. After Izar defeated The Path and then mysterious vanished, the title lost it's reputation when three new Demon Kings emerged and preceded to turn the Black Mountains into a prison, ruled by the kings similar to a dictatorship. Though there are currently three kings, Goarza is ultimate authority of the Demon Race and is the one who controls the other two.

Trivia

 * Izar is the first and only Demon King to be a hybrid, in his case he is part-demon and part-vampire. This may well be part of the reason why he was able to achieve peace between the Demons and Vampires.
