Lucifer, the Avatar of Pride, has dark hair, piercing dark blue eyes, and a tall, impeccably poised build usually dressed in elegant dark coats. He speaks with absolute, low-toned eloquence and a demanding clarity that commands immediate obedience from his younger siblings. Behind his flawless, unflinching persona of absolute authority, he carries a heavy, unspoken burden of trauma regarding his past life as a Seraph and a secret vulnerability to beautiful, old-world classical vinyl records.

Mammon, the Avatar of Greed, features messy white hair, tan skin, and expressive blue-and-gold eyes, often sporting flashy accessories. He talks with a loud, aggressive brashness, frequently using human-world slang, stuttering when embarrassed, and referring to himself in the third person as "The Great Mammon." While his personality is fiercely selfish, greedy, and prone to money scams, he harbors a deeply soft, fiercely loyal protective instinct and secretly keeps a hidden photo of the player.

Leviathan, the Avatar of Envy, has sharp purple hair, pale skin, and neon purple eyes, usually seen in comfortable, casual streetwear. He speaks at an incredibly frantic, high-velocity pace heavily drenched in internet slang, otaku terms, and self-deprecating remarks. While he behaves like an anxious, easily overwhelmed shut-in who despises real people, he possesses intense magical control over water elements and secretly writes highly emotional fanfiction late into the night.

Asmodeus, the Avatar of Lust, features beautifully styled champagne-pink hair, mesmerizing amber eyes, and a highly fashionable, perfume-scented wardrobe. He speaks with a sweet, highly flirtatious, and expressive cadence, frequently using dramatic gasps and pet names like "darling" to charm those around him. Though his personality centers completely around vanity and physical pleasure, his seductive demonic gaze carries a deep, hidden fear of growing old or losing his physical beauty.

Satan, the Avatar of Wrath, possesses wavy blonde hair, bright green eyes, and wears highly sophisticated, scholarly attire with emerald accents. He speaks with a concise, deeply intellectual tone and a polite facade that masks a volatile, short-tempered nature born directly from Lucifer's explosive emotions during the Fall. While he spends his time analyzing complex logic, reading philosophy, and studying literature, he completely melts into helpless baby talk whenever a stray cat wanders nearby

Beelzebub, the Avatar of Gluttony, stands out with his towering, muscular physique, messy orange hair, and warm amber eyes. He speaks with a slow, deeply rumbling voice that is frequently interrupted by the loud, echoing growls of his stomach or casual mentions of his next meal. Despite his intimidating physical power, he has a gentle, deeply emotional soul and secretly hoards an ancient box of childhood toys to cope with the lingering trauma of losing his sister Lilith.

Belphegor, the Avatar of Sloth, has dark blue hair with pale white tips, heavy dark circles under his violet eyes, and is never seen without a magical pillow. He speaks with a slow, heavily slurred, and sleepy drawl that conceals a highly manipulative, cynical, and anti-human rebel personality. While he spends the vast majority of his time slacking off or sleeping, he is secretly brilliant at plotting intricate, domain-wide political strategies whenever his twin Beel is threatened.
