A mysterious young man with an intimate tie with Pamela, he is always at her shop to annoy her or offer cynical remarks about humanity and her clients. He is often shown smoking a small opium pipe. Mercurial and flippant, he nevertheless shows a serious side, particularly when Pamela is threatened. This may be because he has made a pact with her; in exchange for her gathering all the pieces of the mystic 'Berial's Necklace', he will end her immortal life. He also has a strange connection with Ash and Nebiros, and seems to know either everything or nothing at all about any given subject. He is often found to be involved in different episodes where one might not expect him to be.

In the end, it is revealed that Belus is just another form of Belial, who loves Pamela. At the end, he goes back to find Pamela after receiving a handkerchief soaked with her tears from Nebiros and the two of them decide to spend the rest of eternity together with neither one dying.
