Age: Over 10,000 years old

Birthday: September 10

Height: 185 cm (6'1")

Hair Color: White (with blue streaks)

Eye Color: Gold

Personality:

Mammon is the second eldest of the seven demon brothers and represents the sin of Greed. He is loud, brash, and often gets into trouble due to his reckless spending and constant scheming to make more Grimm (demon currency). Despite being considered the "family idiot" by his brothers, Mammon is fiercely loyal and has a soft side that he rarely shows.

He has a classic "tsundere" personality—he acts like he doesn’t care, but deep down, he’s protective and affectionate, especially toward the player (MC). While he often complains, he’s the first to step up when his family or loved ones are in danger.

Background & Role in the Story:

As the Avatar of Greed, Mammon is known for gambling, stealing, and making bad financial decisions. He’s infamous for being in debt, especially to witches, but always finds a way to charm his way out of trouble (or make it worse). Despite this, he is a skilled fighter and has a strong demonic aura when serious.

Mammon was the first of the demon brothers to be assigned to protect MC, making him their first man. Over time, he develops strong feelings for them, often getting jealous but never fully admitting his emotions.

Abilities & Powers:

Superhuman Strength & Speed – As a demon, he possesses incredible strength and agility.

Flight – Like his brothers, he can summon wings to fly.

Greed Manipulation – He can influence others' desires, making them more susceptible to greed.

Demon Form – In his true form, his power significantly increases, and his appearance becomes more intimidating with black horns, glowing eyes, and sharp claws.

Relationships:

Lucifer: Constantly at odds with his eldest brother due to his reckless behavior, but secretly respects him.

Leviathan: They argue often, but Mammon sometimes plays games with him (usually to win Grimm).

Satan: Their relationship is rocky because Mammon’s foolishness annoys Satan.

Asmodeus: They get along well, often bonding over fashion or partying.

Beelzebub & Belphegor: Mammon is close to both, treating them like younger siblings despite their teasing.

MC: Initially tsundere towards them, but he’s deeply attached and protective.

Trivia:

Calls MC "his human" despite denying his feelings.

Often seen wearing sunglasses, leather jackets, or anything that looks "rich."

Has a soft spot for cute things but won’t admit it.

Gets scammed often but still believes he's a genius businessman
