The stage of Kuroshitsuji II opens on the life of Alois Trancy, the young heir to the Trancy earldom. Though he is privileged now, such was not always the case for the hot-tempered boy. Kidnapped and forced into slavery at a young age, he was eventually rescued and returned home, only to have his beloved father pass away soon after. However, there are certain individuals who doubt Alois' story and legitimacy. And rightfully so, because things in the Trancy household are not as they appear, starting with Alois' black-clad butler with supernatural abilities, Claude Faustus. Who exactly is the mysterious Claude, and what connection does he have with Alois? Amid the web of lies and deceit running rampant in the mansion, the bond between Alois and Claude will be tested as hell itself arrives at their doorstep.

Full of wonder and excitement, the Noah's Arc Circus troupe has captured audiences with their dazzling performances. Yet these fantastic acts do not come without a price. Children have mysteriously gone missing around London, correlating to that of the group's movements. Unsettled by these kidnappings, Queen Victoria sends in her notorious guard dog, Ciel Phantomhive; and his ever-faithful demon butler, Sebastian Michaelis, on an undercover mission to find these missing children. Trying to balance their new circus acts with their covert investigation under the big top, however, proves to be quite a challenge. With the other performers growing suspicious and the threat of the circus' mysterious benefactor looming overhead, what the two discover will shake Ciel to his very core.

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.
