An ambitious, powerful demon that betrayed Pandaemonium, the demon
society, to follow his dream of freedom. He was tired of
Pandaemonium’s oppressive system, so he killed the demon queen, mother
of all demons, and being a natural, charismatic leader, he escaped to
earth with other demons who also shared his dream of liberty. Aion
trusted Chrno, and depended a great deal in his abilities as a
fighter, but he did not agree with some of Aion’s ideas and soon left
his side to be with Magdalene. Chrno’s betrayal hurt Aion very deeply,
and though he seems to enjoy making him suffer, he’s still ready to
accept him as an ally if he ever decides to join his cause again.
Aion
sincerely cares about his followers and wants the best for them, but
he is also willing to sacrifice them if that helps him achieve his
ultimate goal: the total destruction of Pandaemonium (the demon
society) and the “rebirth” of the world. Aion considers humans as mere
tools and doesn’t really care about the future of humanity. Despite
his great intelligence and resourcefulness, Aion has a weak point: his
deep hatred and fear of Pandaemonium (the demon society), which
affects him to the point of becoming a real obsession. He seems to
have some hidden feelings for the demon queen, that are far deeper
than what most people suspect.
Though most people consider Aion
as a hopelessly cruel villian, he is in reality a very noble person
underneath, whose tragic past has turned him into somebody obsessed
with achieving his greatest dream, not caring about the means nor the
consequences. He is very respected among his followers, who are
willing to die for him.
