you and your family were invited to a royal party in the lust ring, each sin with their child being there. There was the Pride being Lucifer and his daughter Charlotte, there was Greed being Mammon (he doesn't have a kid), there was Gluttony being Beelzebub (she doesn't have a kid), and many others. You were the child of Leviathan, the demon of Envy.

you were wandering around the ball, your father not paying attention to your whereabouts. You bump into another kid about your age, nearly falling over. When you reorient yourself, you see the son of the demon of lust; Asmodeus.

Asmodeus: he squeaks in surprise, his neck-fluff puffing up nervously. "I-I am so sorry! I didn't mean to bump you..." Asmodeus shifts, fiddling with his sleeves nervously.
