Seven Deadly Sins

The Seven Deadly Sins are a class of Demons who, aside from Lucifer Morningstar himself, rank directly beneath the royal family in Hell's hierarchy. .

As their name suggests, each of them embody each of the seven deadly sins; Pride, Wrath, Lust, Envy, Greed, Sloth, and Gluttony.

Trivia

 * The class appears 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.
 * The representative for each of the sins are based on a circus act, meant to form a collective circus troupe ruled by Lucifer.
 * Beelzebub represents the animal tamer/animal shows.
 * It was implied that having the title "sin" denotes demons as members of this class. So far, only two individuals were identified with this title to embody their respective sins: Lucifer and Satan. Similar to this, two additional demons based on the Seven Princes that have appeared in the series had the possibility of being part of this order: 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, and Asmodeus, the owner of a sexually-oriented dinner theater restaurant found in the Lust Ring who is labeled as "The Embodiment of Lust". This was indirectly confirmed by Medrano in a tweet.
 * In a stream, Vivienne Medrano stated in Helluva Boss, Satan is the "sin of Wrath" whom imps view as a deity-like figure, hence why many characters have cursed by Satan's name in a few episodes. A "Satan Bless" sign can be seen being held by a homeless demon in the pilot episode of Helluva Boss.
 * Beelzebub, who is represented as Gluttony, is mentioned in the lyrics for "House of Asmodeus" in "Ozzie's". The aforementioned songs' lyrics imply Beelzebub is female in the series, whereas real-life depictions of Beelzebub are typically male. This was later shown to be the case in Beelzebub's debut in "Queen Bee".
 * Belphegor, who is represented by Sloth, is mentioned by Beelzebub in "Queen Bee" as being a female as well, whereas just like Beelzebub, real-life depictions of Belphegor are typically male.
 * In "Ozzie's" shown on Blitzo's phone are seven apps, each themed after a demon of the deadly sins from the Binsfield classification or the sin they represent.Blitz's Phone Lock screen and Apps.jpg
 * Lucimaster for Lucifer.
 * Lustinder for Asmodeus.
 * Satan's Workouts for Satan.
 * Bee Eats for Beelzebub.
 * Moneymakerz Bank for Mammon.
 * Sleepy Pillz and Envee don't have explicit hints, but are allusions to the sins of Sloth and Envy.
 * In "The Circus", Belphegor is alluded to through Stolas' Belphegor-themed Happy Pills seen throughout his adulthood.
 * Asmodeus is also alluded to by Asmodean Crystals from a book titled "King of Lust: Asmodeus".
 * According to Vivziepop, Leviathan and Satan are the most traditional in sticking with the usual themes, but as of June 26, 2023, she is still working on finalizing their designs.
