Mammon is the Demon Lord of Greed and one of the seven ruling demon lords in the anime Seven Mortal Sins. She embodies the sin of avarice and is obsessed with wealth, profit, and material gain. Her drive for riches is partly rooted in her backstory: she was left by her unnamed husband with a staggering debt and the responsibility of raising 500,000 children. To support her enormous family and clear her debts, Mammon operates primarily in London, where she engages in real estate ventures and sells home-brewed magical potions. She seizes every opportunity to turn a profit, and her cunning business instincts make her a formidable figure among the demon lords. Physically, Mammon is depicted as a tall, voluptuous woman with waist-length blonde hair, blue eyes, and large curved horns that protrude from the top and back of her head, often adorned with an ornate hairband. Her appearance is overtly sensual, and she frequently uses her beauty and charm to manipulate others, leading many to underestimate her. However, beneath her greedy and manipulative exterior, Mammon shows a protective and caring side, especially toward children. This duality adds complexity to her character, as she is both a ruthless businesswoman and a devoted mother. In the overarching story, Mammon is one of the seven demon lords who originally seal away Lucifer’s angelic powers and rule over Hell. She serves as an antagonist who challenges the protagonist, but her motivations are often driven by practical, profit-oriented concerns rather than pure malice. Among the often eccentric and unreasonable demon lords, Mammon stands out as a pragmatic realist, hardworking and no‑nonsense. Her key relationships include her fellow sins, with whom she sometimes collaborates but also competes for power and influence. Her devotion to her children is one of her most defining traits, motivating her to accumulate wealth and secure their future. As a demon lord, Mammon possesses considerable supernatural abilities befitting her rank, though her specific combat powers are not extensively detailed; she is considered one of the strongest among the seven sins and is feared by many lesser demons. Throughout the series, Mammon undergoes little personal transformation, but her role as a supporting character reinforces the theme of greed and its consequences within the world of the seven deadly sins.
