About the Black Butler Manga Volume 12

A pleasure cruise turns to horror when chaos descends upon the maiden voyage of the luxury liner Campania, the reanimation of corpses under the influence of the mysterious Aurora Society's 'absolute salvation' going awry. Earl Ciel Phantomive and his singular butler Sebastian get more than they bargained for as soulless loved ones return from the grave only to attack their families and other passengers on a ship that is now all but a floating coffin.
