@Omega I think unlike the title of Lucifer, Ishibumi has made Archangel an inheritant title. Reason being is because all the Seraphs are archangels in religion, but instead them all being archangels, Ishibumi made it where the leader of the Seraphs is the only archangel and the position is inherited by whoever is basically second in command in the Four Great Seraphs [seven possibly in the future]].
