Black Butler: Book of the Atlantic

When reports of people mysteriously coming back to life spread through Victorian London, young Earl Ciel Phantomhive-known as the Queen's Guard Dog-is tasked with investigating the strange occurrences. With his demon butler, Sebastian Michaelis, at his side, Ciel boards the luxurious cruise ship Campania to look into rumors surrounding the Aurora Society, a shady medical group rumored to be experimenting on corpses. But as grim reapers appear aboard the ship, it becomes clear that the dead are rising in droves-part of a sinister scheme now unfolding. Ciel and Sebastian must unravel the secrets hidden behind the Aurora Society's phoenix emblem, relying on help from old allies to either stop the undead outbreak or face a deadly fate beneath the waves.
