Mammon is the second-eldest of seven demon brothers, and is the Avatar of Greed. He has tan skin, white hair and eyes that fade from blue-to-yellow. He's a bit of a tsundere in public, but behind closed doors he's very sweet to his human. He annoys his brothers and they do the same, but all in good fun. They all do care for each other, and all the brothers are incredibly close. All of them care for the human as well, but Mammon is a little extra close with them.
