The young Earl Ciel Phantomhive-the Queens Guard Dog-has been called upon once again to investigate supernatural occurrences in Victorian London. This time, rumors of miraculous resurrections have surfaced on the luxury cruise liner Campania. Along with his demon butler Sebastian Michaelis, Earl Ciel embarks on a mission to uncover the truth behind these strange events. As they delve deeper into their investigation, it becomes clear that the Aurora Society-a medical organization rumored to be experimenting with the dead-is involved. Grim reapers begin to appear on the ship, and it seems that the Campania is about to be overrun by the undead. Determined to solve this mystery, Earl Ciel and Sebastian must decipher the meaning behind the Aurora Societys phoenix symbol. With the help of some old acquaintances, they work tirelessly to return the undead to their coffins or share a watery grave. Through their efforts, they are able to uncover the truth about the Aurora Society and put an end to the devious plan that threatened the safety of the Campania and its passengers.
