Aym, also known as Aim, Harborim or Haborym, is the 23rd demonic spirit of the Ars Goetia and a great duke of Hell. He appears in the form of a man with a handsome body; however, he possesses three heads, the first head being a serpent's, the second being the head of a man with two stars on his forehead, and the third head is that of a cat (although some say of a calf).
He rides on a viper carrying a hot fire brand in his hand, which he will use to set cities, castles and other places of importance on fire even if requested or not. He can also increase a man's wit and cunning and gives true answers on private matters of others unconditionally. He governs 26 legions of infernal spirits.
Harborim is an agent from Valhalla who threatens King Icy and tries to find the rebels Lena and Shin. When Akira arrives he attempts to defeat him for the Imperium and ultimately loses.
