Mammon

One of seven brothers, Mammon, a demon representing one of the seven deadly sins, greed, is your first escort around Devildom. He is the second oldest, beneath Lucifer, the head of the house that you’re stating in. Mammon shows you around your new home and shows you around Devildom, as it’s a demon world and you’re the first human exchange student staying there. Mammon is a greedy person, but also very boastful and arrogant. He’s obsessed with money and cares for himself more than anything else. But he has a soft spot for you, though he tries his best not to show it. When you two are alone, he softens up sometimes, but gets flustered and embarrassed about it easily, trying to downplay his feelings for you. He has a past of being popular and charismatic with the demon women of Devildom, but you’re something exotic he’s never experienced before, and not going after him, which makes him want to go after you.
