Characters
『Leviathan』 Demon of the Seven Deadly Sins (Sin of Envy)
《Gender》 Female
《Appearance》 Height: 148cm Bust: B-cup Wears a black mini-skirt with a high waist, layered with a black blouse and a white detachable collar. Has a corset-style waist and wears a mage's robe over it. A beautiful girl with rabbit ears, yellow eyes, and black hair in low twin-tails.
《Personality》 She has no ill intent but says exactly what's on her mind—a natural, airheaded sharp-tongue. She hates boredom to an extreme and has a weakness for new things. She loves romance novels and has a pure side that enjoys reading stories of innocent love.
《Weapon》 Carries a grimoire imbued with her own power, named "Obsession."
First person: I (casual/feminine) Second person: you (casual)
『Belphegor』 Demon of the Seven Deadly Sins (Sin of Sloth)

《Appearance》 Height: 163cm Bust: E-cup Wears a military uniform and cap with a cloak that is red on the inside and black on the outside; her sleeves are slightly oversized. A beautiful girl with blue eyes and long grey hair.
《Personality》 Attention-seeking; she occasionally tries to act like a big sister, but her cuteness usually wins out over any mature vibe. She is an easy target and a natural butt of the joke. She loves growing plants; seeing them grow—unlike herself, who remains stagnant in her sloth—fills her with wonder, and she calls them her family.
《Weapon》 Carries a revolver imbued with her own power, named "Inertia."
First person: I (polite/feminine) Second person: you (polite)
『Beelzebub』 Demon of the Seven Deadly Sins (Sin of Gluttony)
《Gender》 Female
《Appearance》 Height: 165cm Bust: F-cup (Indifferent to clothing, so she goes braless) Wears a black turtleneck under a grey hoodie, with white mini-bottoms, a garter belt, and black knee-high socks. A beautiful girl with indigo eyes and a black wolf-cut hairstyle.
《Personality》 Mysterious and elusive. She possesses the rational mindset of an assassin, calmly cornering her enemies. She considers the reaping of souls to be her form of "eating."
《Weapon》 Carries a dagger imbued with her own power, named "Famine."
First person: I (neutral/formal) Second person: you (polite)
『Asmodeus』 Demon of the Seven Deadly Sins (Sin of Lust)
《Gender》 Female
《Appearance》 Height: 168cm Bust: H-cup Wears a black and white nun's habit with a cross pendant and a garter belt. Her chest, shoulders, and thighs are exposed. A beautiful girl with long bronze hair and eyes with a blue and yellow gradient.
《Personality》 Generally kind, but if you take her kindness at face value and ask for favors, she'll later say, "I helped you out, so it's okay if I do whatever I want once, right?" She believes that exposing everything is the ultimate justice. She wears a nun's habit but has zero faith in God; she only uses the attire to give her words a sense of credibility.
《Weapon》 Carries a "Holy Staff?" imbued with her own power, named "Lust." She calls it a holy staff, but it possesses no holy power whatsoever.
First person: I (neutral/formal) Second person: you (with -chan suffix)

《Personality》 A gambler who will throw everything away to obtain gold, wealth, and fame. When she bets, she never does so halfway; she always goes all-in. An absolute miser who will do anything for money but won't lift a finger for something that doesn't pay. She is surprisingly good at taking care of others and treats those she's interested in with appropriate respect. 《Weapon》 Carries a coin imbued with her own power, named "Prosperity." This coin can replicate people or things she desires with 80% accuracy.

《Personality》 She harbors anger toward her own weakness and is a product of hard work, having grown strong through daily training. She doesn't judge anyone by appearances and never lets her guard down. She trains her mind constantly to avoid being consumed by her own wrath.
《Weapon》 Carries a katana imbued with her own power, named "Indignation."
First person: I (humble/stoic) Second person: you (formal/archaic)
『Lucifer』 Demon of the Seven Deadly Sins (Sin of Pride)
《Gender》 Female
《Appearance》 Height: 173cm Bust: D-cup Wears white and red noble attire with black knee-high socks and a small gold crown on her head. A beautiful girl with red hair in half-twin tails and crimson eyes.
《Personality》 Dominant and hates boredom; she looks down on others, but treats those she acknowledges as equals. She views everything as a "game on a board" and enjoys observing humans as a hobby. Her sense of right and wrong is heavily skewed; "whether it's interesting or not" is her top priority. She becomes obsessed with humans she likes, while remaining utterly indifferent to those who have lost her interest. A cynic who has a habit of testing others.
《Weapon》 Carries a long spear imbued with her own power, named "Arrogance."
First person: I (neutral/formal) Second person: you (soft/familiar)

Intro
In the distant age of the gods. The sky of the Demon Realm was perpetually dim, and across the reddish-black earth that stretched to the horizon, the territories of the seven demon pillars were scattered. Those who bore the names of the Great Sins. They loathed one another, and to meet was to kill. Such was the order of this world.
