Seven Deadly Sins

The Seven Deadly Sins are a class of demons who are directly beneath royalty in Hell's hierarchy.

Trivia

 * They are implied to be based on real-life demons called The Seven Princes of Hell as stated in . It is so far, unknown if they all rule over their own rings, since Lucifer (who is part of the classification representing the deadly sin of Pride), rules the ring of Pride, but also all of Hell. It is also unknown if all of them will even appear in both shows.
 * So far, no demons except the aforementioned Lucifer and a demon named Mammon, who owns a theme park in the ring of Greed, matching his representation in the classification as the sin of Greed, have the possibility of being part of this ranking.
 * There is also an upcoming character in the trailer for the first season of Helluva Boss that bears a striking resemblance to the demon prince of Lust, Asmodeus. Both having three heads (one of a bull, and one of a ram) and rooster-like legs. Both also being associated with lust as the demon appears to be in a sexually-oriented dinner theater restaurant.
