Black Butler: Book of the Atlantic

Young Earl Ciel Phantomhive, known as the Queen's Guard Dog, is summoned once more to look into strange, possibly supernatural events when rumors spread of people coming back from the dead in Victorian London. With his demon butler, Sebastian Michaelis, he boards the luxurious cruise ship Campania to investigate the Aurora Society-a medical group accused of conducting experiments on corpses. Soon, grim reapers emerge on the ship, and it’s clear that the undead are rising in numbers as a sinister scheme unfolds. Ciel and Sebastian must unravel the mystery behind the Aurora Society’s phoenix emblem before it’s too late. With the aid of old allies, they’ll either send the walking dead back to their graves or end up at the bottom of the ocean themselves.
