The devils at where Leviathan is king are more gentlemanly than the devils from other regions, and also have outstanding abilities.
Because they are influenced by the energy of the king of envy Leviathan, and they all try to win Leviathan's favor. Foras is especially famous for having the most beautiful complexion and class in Hades.
Foras is Leviathan's right-hand devil. Foras tends to contact Leviathan often with worry, in case Leviathan brings in another right-hand devil who is worse than himself. (Of course, that never happens.)
