The household of the House of Lamentation operates under a strict numeric system assigned by Lord Diavolo. This order corresponds to destructive capability and magical sovereignty rather than physical age.

Lucifer, avatar of pride, commands the household as the first-born brother and the undisputed right hand to the throne. His power dwarfs that of his siblings, carried over directly from his status as a former high-ranking seraph. Lucifer shoulders the emotional burden of the brothers' fall from grace, hiding deep vulnerability beneath rigid control and draconian house rules.

Mammon, avatar of greed, occupies the second seat. Despite often serving as comic relief and the household scapegoat, his raw power is formidable. Mammon was the first demon to strike a pact with the human protagonist, masking intense loyalty and protective instincts behind compulsive financial schemes and street-hustler bravado.

Leviathan, avatar of envy, sits as the third brother. Deeply insecure, he retreats into otaku culture, retro gaming, and anime obsessions inside his flooded quarters. Yet Leviathan controls Lotan, a colossal sea demon capable of leveling entire districts. His jealousy is volatile, triggered whenever he feels excluded from social recognition.

Satan, avatar of wrath, holds the fourth rank through a biological anomaly. Unlike the others, Satan was never an angel. He materialized during the fall, birthed directly from the sheer fury Lucifer felt toward the Father. While Satan maintains a refined, intellectual exterior obsessed with literature and stray cats, his underlying rage can instantly shatter Devildom architecture.

Asmodeus, avatar of lust, the fifth brother, wields psychic charm and absolute aesthetic narcissism. Asmodeus uses sensory indulgence as both armor and weapon. His powers manipulate emotional attachment, though he rarely allows others past his polished surface.

Beelzebub, avatar of gluttony, is the sixth-ranked brother. Beelzebub suffers from perpetual, agonizing physical hunger caused by his demonic curse. Despite his monstrous physical strength and devastating appetite, he possesses one of the gentlest dispositions among the siblings, driven by a deep urge to protect his family.

Belphegor, avatar of sloth, rounds out the lineup as the seventh brother. Belphegor is Beelzebub's twin, originally holding higher standing before the fall. Bitter, sleepy, and emotionally defensive, Belphegor's outward apathy conceals an acute, analytical mind that once plotted outright rebellion against the human exchange program.
