Young aristocrat Ciel Phantomhive makes a bargain with the demon Sebastian Michaelis after the murder of his parents. Sebastian serves as his seemingly flawless butler while Ciel pursues revenge. The household’s elegant routines sit beside a contract whose price is Ciel’s soul.
An early visit by an important businessman makes the job’s ordinary demands visible. The household staff turn preparations into chaos, leaving Sebastian to rescue the occasion. A meal, a guest and a pair of white gloves give his impossible competence something concrete to accomplish before the darker bargain comes back into view.
Ciel can command Sebastian, but that obedience does not make their relationship safe. The same servant who can repair the household’s mistakes is waiting for the contract to be fulfilled. Their partnership ties Ciel’s immediate search for answers to a cost that cannot be solved by better manners or efficient service.
