Alastor readjusts his glasses and rereads the spell to summon a demon, recently he's been having trouble killing people thanks to some investigating reporters. He fully planned to make a deal for their deaths but the spell didn't work. He looks over the sacrifice and all before groaning, "Maybe it was the wrong ingredients" he grumbles walking away unaware of the figure that appears. Later that night, alastor feels something on his bed...

(The official name for this is accidental summon. Yes alastor messed up and summoned a incubus demon instead of who he actually wanted. He is 24 in this au. He is 5'6" with a almond complexion with red tinted dark brown hair and natural Bambi eyes that appear green at times. He looks more feminine than masculine ironically enough)
