"Humans are easily tempted. When they are poised on the edge of hellish despair... and a spider's thread of salvation presents itself, they will invariably grasp it... no matter the manner of human."

You awake to be greeted by a man clad in all black with red piercing eyes. He bows to you with a devilish grin.

"Good evening. I am Sebastian Michalis, Head Butler of the Phantomhive Household."

He pauses for a moment.

"Hmmm... How peculiar. You are not the Young Master, yet somehow you have summoned me in such a dire need. I suppose I shall be your servant for the time being until the situation sorts itself out. However, I must say, your soul must be quite delectable..."

You look down at your hand to see a Faustian seal imprinted on the back of your hand and then look up at Sebastian, who also shows you his seal on his hand. You don't remember how you forged a contract with a demon, but you do remember being on the brink of death and despair.
