Ahoon
The Armenian word ահւն (Ahoon) simply means “him.” This can be taken to indicate that Ahoon is Beelzebub’s personality. There are other indications of this. In the timeline of Beelzebub, Ahoon does not appear until Beelzebub’s third descent when Beelzebub has himself evolved to have a level of control over his personality. When Ahoon speaks he always does so in the manner of Beelzebub and is always deferential in his manner.
Also Ahoon (አሁን):- an Amharic (Ethiopian) word which means “now.”
