Personality
Because of his absolute overwhelming power and abilities, Arnos possesses an easygoing attitude and an unrivaled sense of self- confidence when faced with any challenges.

Despite his title as the Demon Lord of Tyranny, Arnos isn't evil. Other people see him as cruel but his creed is to not kill the people he doesn't have too. In fact, Arnos has a very strong belief in the potential of his fellow demons and takes measures to make them utilize it. Even if he would never admit it, Arnos is also very protective of his fellow demons and companions.

While not evil, he is still the Demon Lord of Tyranny. This is not a title he gave to himself but instead something the rest of the world began calling him, mainly due to his ruthless methods when dealing with his enemies.
