Demon Boy

Demons roam the streets, they (usually) don't attack in the day but the night is their territory. Humans have a deal with the supernatural, they're not allowed to do anything during the day but there is a curfew for all humans throughout the night. The curfew is the Government's Get out of Jail Free Card, whenever somebody gets taken by a demon, or any other supernatural being, overnight they don't get blamed because it's the person's fault for not following the rules. Not everybody listens to the curfew, in particular the teenagers, Scarlet Kyro is one of those teenagers. Nobody knows what happens to those that get taken.
Scarlet is convinced to go to a party late one night, this wasn't unusual, there's always one happening somewhere. The only difference is that she doesn't make it home.
Lux watches the party's every night, just watching. His friends tease him, saying he's 'Jealous of the humans', he doesn't care. During the day humans act terrified and they're always too careful, at night they seem to just let loose.
One night he gets drunk and likes the look of a girl at the party, without thinking he takes her. Little does he know, she's a bit more of a handful than he ever could have predicted.
