One hell of a Butler (black butler RP)

The demon crow grinned widely at the human in the middle of the alternate space.
"Are you sure?" he said. "Once you make this contract, there is no going back." As the human lay floating in the dimensional space, he turns his impatient head to the demon.
"Yes, I'm sure, now just do it!" The human yelled impatiently. A mark is put on the humans left eye and within moments, the human is back surrounded by others who wished to "cleanse" him, as the idea was given to them by the angel of massacre. None of them were standing anymore, though. All were either bleeding to death from deep wounds or already dead. A tall man appears in front of the young human. His raven hair sets neatly around his face and his red eyes peer out from pale skin. He wears a dark grey suit, nicely ironed, and a perfectly white shirt under the coat. Barely a drop of blood is on him as his gloved hand extends to the human to help him up.
"Would you like some assistance, Master?"
