Satan

Lucifer is a slender fallen angel (standing at 158 ​​cm tall) and the King of Hell. He has fair skin with rosy cheeks, blond hair with thin, light coral streaks over thick, paler highlights, and eyes with light yellow sclera and red pupils. His mouth is full of sharp teeth, his hair is cut short and slicked back in a ducktail with a single tuft of hair sticking out, his pupils are widened like a snake's, and his cheeks are a paler shade of red. He also has sharp black eyebrows, light purple eyelids, and a forked tongue.

Lucifer's red and white attire resembles that of a circus ringmaster: he wears a wide-brimmed white hat with a golden snake and red apple above golden spikes resembling a crown, and a white suit with red lining, red trim, and eight gold buttons. The coat is worn over a light-colored red-and-white striped vest with two gold buttons and a small black bow tie with accessories.

He also wears black knee-high heeled boots and dark gray forearm-length gloves. He wears a gold ring on his left pinky, presumably the wedding ring from his marriage to Lilith.

Lucifer typically carries a black cane with an apple tip, matching his hat. Due to his angelic origins, he possesses six white wings with red feathers. When Lucifer assumes his full demonic form, he gains a pair of red horns with a fiery sphere between them, and the snake and apple from his hat hover above them, resembling a halo. His eyes also change: the sclera turns red, and the pupils turn yellow. He also gains a black, spiked tail, ending in a triangular tip with a red heart at the center, and his fingertips turn red.

Satan (the sin of wrath) is depicted as a huge, muscular, red dragon-like demon with four eyes and horns. He wears a black and red leather vest and black pants, adorned with an orange belt with a skull. Orange lava stripes are visible on his wings, neck, and left arm, while his other arm is red. His two outer horns are striped black and red, while his two inner horns are black and white, arranged in a pitchfork-like fashion. He also has a large tail, colored red and orange, with spikes protruding from his back.

Character In keeping with the sin he represents, Satan is depicted as a very angry demon with anger issues and fits of rage, sometimes causing him to lose control. His uncontrollable rage is so intense that he requires a demon therapist to act as a "shoulder-bearer" to remind him to remain calm. Despite this, he is able to maintain a level head most of the time.

He shows little concern for the demons below him in Hell's hierarchy, especially imps, despite claiming to be their creator. To him, imps (and likely hellhounds and other mortal spawn of Hell) are mere pawns, serving only to carry out orders and do their jobs. Even the royal demons were not spared his indifference, despite being held in far greater esteem.

Belphegor (the sin of sloth) is a light purple demon resembling a sheep, with long, fluffy wool instead of hair. On her head is a melting candle, similar to that found on Baphomet demons, and the tips of her ears are designed to match the melting wax of her candle.

She has a pair of thin, black, pointed horns on the top of her head, and her hands are painted a dark purple, ending at the fingers. She has an elongated white neck.

She has ten eyes on her body, divided into two pairs. Two are primary, with horizontally positioned light pupils. The other two are slightly smaller, positioned directly above the primary eyes, and the last eye of the first five is positioned on top of the others. The remaining eyes are arranged vertically along her neck, three of which have black whites, white irises, and long eyelashes, while two are completely purple.

Character Although her identity has not yet been revealed, as the Sin of Sloth, Belphegor often sleeps. There are some hints that, like some of her fellow Deadly Sins and other high-ranking demons, she is indifferent to lower-class demons, such as imps.

Mammon (the sin of envy) is a rather plump demon with four arms, resembling a jester. He has green eyes, green teeth, and a blue tongue.

He wears a green and dark green jester's cap with three bells and small dollar signs on the tips. He also wears a jester's collar that is half dark green and half green with a yellow trim at the bottom and black diamonds.

Mammon's jester's robe consists of two layers of different colors: the first is dark green, the second black, both with yellow trim and bells at the bottom, surrounded by green diamonds. The sleeves are asymmetrical: one on each side is dark green and black, while the other two have white and pale green stripes.

Full demonic form In his full form, Mammon takes on the appearance of a spider: he gains four extra pairs of eyes, eight long, sharp legs, and a pointed thorax, a feature common to almost all arthropods. His ears also become more pointed, giving his head the appearance of his image on banknotes.

Character As befits the sin he personifies, Mammon is extremely vain and greedy, unconcerned with the well-being of other demons, only concerned with how much he can earn from them to satisfy his own greed. Although he seems to have his own standards, as he dislikes taking change from poor children. In public, however, Mammon is friendly.

Leviathan (Sin of Envy) is a two-headed fish demon whose body is divided into two halves: the left half is white and the right half is indigo. Both heads sport long, white hair that resembles fins and is styled into a mohawk. The left head has more humanoid features, with webbed ears and bright blue eyes with black sclera and light blue eyeshadow. The right head, on the other hand, is more animal-like, with a longer neck, pupil-less seafoam eyes, and a fanged eel-like snout. Furthermore, the left head's hair has pale pink streaks with a black stripe and a purple gradient within. The right head's hair has a bioluminescent hue, with black streaks on the crown, a dark purple-blue gradient within, and green spots scattered throughout.

Leviathan wears a black, sleeveless, cropped top with a high collar, a diamond-shaped neckline, and two downward-facing swirls, the right one purple and the left lavender. She wears a black skirt with a semicircular headband divided into stripes the same color as the swirls. She also wears elbow-length gloves: the left one is black and the right one is white. Each headpiece is topped with a light blue pearl necklace, and only the left one sports pearl earrings and a matching light blue belt.

Character Both Leviathan heads appear to have independent personalities. The right head is more cynical and has greater control over the main body. The left head, by contrast, appears relaxed and reserved. It was even friendly toward Mammon, unlike the right head, and became angry when the right head moved away from him. The relationship between the two heads was also demonstrated when Mammon invited Leviathan on a date after Blitz's trial. The right head showed active irritation toward Mammon and attempted to ignore him. Leviathan's left head, however, seemed genuinely to enjoy his company and looked hopefully at the right head, indicating that it hoped she would allow them to accept Mammon's offer.

Beelzebub (the sin of gluttony) is a tall, fox-like demon with insect-like features, such as multiple arms, a pair of antennae, and a pair of small wings. She has yellow and black striped fur like a bee, and black spots on her arms and legs.

Her hair and tail are either honey or lava lamp fluid. They glow bright pink, blue, and orange, and Beelzebub's belly is lava lamp fluid. She has a pink stripe on her head in the shape of a small heart.

Beelzebub's outfit consists of a pink, sleeveless crop top with a sweetheart neckline and a pair of white short shorts. Beelzebub also wears a black choker and a black bra. Personality: Beelzebub presents herself as an extremely friendly and energetic party girl, a clear extrovert. With her cheerful attitude, she creates a vibrant atmosphere for her guests, allowing them to enjoy food and alcohol to their heart's content, like her Beelzebub.

Asmodeus (the sin of lust) is a large, tall demon with an uneven posture and brightly colored clothing. He has long arms and toes, a broad upper chest and a narrow waist, and three rooster-like tail feathers colored red, black, and ivory.

His head is dark blue with long hair or feathers reaching his chest. He also has a mane of thick blue hair with two additional faces—a ram and a bull—on the right and left sides, respectively, which react to his words and can speak and sing along with him. He has glowing green eyes and a mouth on his main head.

He wears a dark blue vest and a red shirt with blue cuffs and red heart-shaped cufflinks. His torso is covered in two pairs of glowing white stripes, running down his chest to a heart-shaped clasp on his stomach. On his main head is a top hat with red and white feathers protruding from its red headband. On his feet, he wears jagged high-heeled shoes with red tips. He also wears a tall black top hat. In his demonic form, his mane transforms into light blue flames, which also cover his body. His face and rooster tail turn a bright crimson. Personality: Asmodeus acts very boastful and arrogant, especially when something contrasts with his reputation as the embodiment of lust. He has shown himself to be very proud of his status, not hesitating to humiliate those who act sentimentally with their partners, perhaps out of disgust.

Stolas (the Goeti demon) is a tall and graceful owl demon. He has narrow, almond-shaped, bright red eyes with no visible pupils or irises (though when angered, small yellow pupils appear). Instead of a normal nose, he has a small, black owl-like beak. His body is blue. His long, bushy tail consists of several blue-light blue feathers with dark tips. Gray-blue feathers protrude from his chest, like a frill. From his neck upward, his feathers change from gray-blue to dark blue, while his face is distinguished by a white heart shape (his eyes are heavily outlined, with noticeable thin lines beneath them). His slender arms and legs are black, the feet themselves resembling long owl claws.

Stolas wears a top hat. Its base resembles a mask shaped like wings or feathers, with slits for the demon's upper pair of eyes. A large golden crown, a symbol of Stolas's power, is affixed to the top hat. This hero is depicted in royal attire: a red tunic with gold buttons, gray trousers, and a plush maroon frock coat with a white fur collar with dark spots and puffy striped sleeves. Small tufts of white fur hang from his elbows. Personality: A regal and pompous demon, as expected of a high-status member of the royal family. He dresses in clothes befitting his role and has a luxurious mansion with numerous large portraits of Stolas himself and his small family.
