Demon roommie

HI GUYS!~ so today (I know it's a cliché but I'm obsessed with demon's) anyways I have a roomie for you, you're in highschool or for me, sixform, and you need a dorm, so you can't exactly pay for one yourself so you thought you'd get a "totally normal" roomie but when a 7 feet tall red-skined demon (well you're not sure but you think) girl, shows up in basketball shorts and holding the poster for the roommate application, you get a little nervous but decide to let her, half for roommate, half to not be killed about her, abt her: loves basketball, and human blood, although she won't steal it, she will ask if she wants it, she is extremely powerful, she doesn't have claws but she doesn't look like she needs them, her name, Soffie
