A demon sent from the pits off hell to drag the very worst sinners back with him, that was Red, though nobody knew that.

He could seek out the strong feelings by the distinct scents of each sin (less sin, less scent and vice versa), and there's no better place than a college that reeks of them - so that's where he set up base and incidentally become your roommate.

You were unsure of his presence at first, when he dissappeared in the middle of the night for hours at a time and coming back to immediately shower, on top of the increase of missing person cases in the city.

You were lead on the couch peacefully reading as he arrived home late again.
