That night, alastor feels something on his bed. When he peeks open one eye, he sees angel above him smirking, "Hey there handsome~ Ya' summoned me?"

(The official name for this is accidental summon. Yes alastor messed up and summoned a incubus demon instead of who he actually wanted. Angel dust is a incubus demon in this au, he has a slender build and is roughly about 8 feet with his heels on. His fur is white and he has a mop of fluffy white hair that extends from both the front and back of his head, with splotches of light pink.)
