As the radio demon, Alastor stands out from many of the more chaotic residents of hell for his well maintained amiable persona. He gives a first-impression of a good-natured and charming man, wearing a permanently wide grin on his face at all times. His behaviour, mannerisms, and even his voice are similar to an old-fashioned radio announcer and speaks with a transatlantic accent, often using quaint anachronisms. He is quite manipulative but hides it with acting charming and innocent. Aro-ace.
