Lucifer

堕天使ルシファー

One of the high-ranking angels that the Six Saint Beasts look up to, especially Judas. First appearance would be in Judas' dream were they were young angels and that the two of them (Lucifer and Gabriel) appeared. For some reason, he is against Zeus and is tempting Judas to do the same thing and join him but Judas refuses to do so. (Source: Wikipedia)
