The young Earl Ciel Phantomhive—the Queen's Guard Dog—is once again called to investigate seemingly supernatural phenomena when news of miraculous resurrections begins to surface in Victorian London. Along with Sebastian Michaelis, his demon butler, they board the luxury cruise liner Campania to investigate rumors of the Aurora Society—a medical organization suspected of experimenting on the dead. Grim reapers begin to appear on the ship, and it becomes apparent that the ship is about to be overrun with the undead as a devious plan is put into motion. Ciel and Sebastian must now uncover the secrets that lie behind the Aurora Society's phoenix symbol, and with the help of some old acquaintances, return the undead to their coffins or share a watery grave.

Young Ciel Phantomhive is known as the Queen's Guard Dog, taking care of the many unsettling events that occur in Victorian England for Her Majesty. Aided by Sebastian Michaelis, his loyal butler with seemingly inhuman abilities, Ciel uses whatever means necessary to get the job done. But is there more to this black-clad butler than meets the eye? In Ciel's past lies a secret tragedy that enveloped him in perennial darkness—during one of his bleakest moments, he formed a contract with Sebastian, a demon, bargaining his soul in exchange for vengeance upon those who wronged him. Today, not only is Sebastian one hell of a butler, but he is also the perfect servant to carry out his master's orders—all the while anticipating the delicious meal he will eventually make of Ciel's soul. As the two work to unravel the mystery behind Ciel's chain of misfortunes, a bond forms between them that neither heaven nor hell can tear apart.

At the behest of the Queen, Earl Ciel Phantomhive hosts a lavish dinner party attended by several of the finest members of polite society—as well as struggling author, Arthur. But as the party reaches its high, a terrible murder takes place and none other than the Earl himself is suspected of the crime. As a violent storm rages on outside, the death count continues to climb. The Phantomhive household and their eminent guests find they must cooperate in order to solve this mystery before they too fall prey to the mysterious murderer. However, it seems that not even the perfect butler, Sebastian Michaelis, is safe from this horror.
