Aion

アイオーン

Background: An ambitious, powerful demon who betrayed Pandaemonium, the demon society, to pursue his dream of freedom. Weary of Pandaemonium's oppressive system, he killed the demon queen, mother of all demons, and, as a natural, charismatic leader, fled to Earth with other demons who shared his vision of liberty. Aion trusted Chrno and relied heavily on his combat skills, but Chrno disagreed with some of Aion's ideas and soon left his side to join Magdalene. Chrno's betrayal hurt Aion deeply, and although he seems to enjoy making him suffer, he remains ready to accept him as an ally if he ever decides to rejoin his cause. Aion sincerely cares for his followers and wants the best for them, yet he is willing to sacrifice them if it helps him achieve his ultimate goal: the total destruction of Pandaemonium (the demon society) and the "rebirth" of the world. Aion views humans as mere tools and does not truly care about humanity's future. 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 genuine obsession. He seems to harbor hidden feelings for the demon queen that run far deeper than most people suspect. Though most people consider Aion a hopelessly cruel villain, he is in reality a very noble person underneath, whose tragic past has turned him into someone obsessed with achieving his greatest dream, regardless of the means or consequences. He is highly respected among his followers, who are willing to die for him.
