Watch Black Butler: Book of Circus Online

New season of

Queen Victoria of England has ordered her loyal watchdog, 13-year-old Earl Ciel Phantomhive, to investigate a series of suspicious deaths in southern Germany. Across multiple villages, all the victims have one thing in common: they had entered the so-called Werewolves' Forest right before they developed strange deformities and subsequently died. The rumors put blame on a "witch's curse," the nearby villagers' firm belief based on old folklore. Unconvinced that anything truly supernatural is at play, Ciel and his contracted demonic butler, Sebastian Michaelis—along with the rest of the Phantomhive servants—come across an isolated village in the Werewolves' Forest. Its residents are only women, hostile toward the outsiders and serving a young girl with emerald eyes and bound feet, Sieglinde "Green Witch" Sullivan. Ciel and Sebastian investigate to uncover the truth, but as they soon fall victim to the curse themselves, it appears that there is more to the local myths than meets the eye.

The young Earl Ciel Phantomhive—the Queen's Guard Dog—is once again called to investigate seemingly supernatural phenomena when news of miraculous resurrections begins to surface in Victorian London. Along with Sebastian Michaelis, his demon butler, they board the luxury cruise liner Campania to investigate rumors of the Aurora Society—a medical organization suspected of experimenting on the dead. Grim reapers begin to appear on the ship, and it becomes apparent that the ship is about to be overrun with the undead as a devious plan is put into motion. Ciel and Sebastian must now uncover the secrets that lie behind the Aurora Society's phoenix symbol, and with the help of some old acquaintances, return the undead to their coffins or share a watery grave.

At the behest of the Queen, Earl Ciel Phantomhive hosts a lavish dinner party attended by several of the finest members of polite society—as well as struggling author, Arthur. But as the party reaches its high, a terrible murder takes place and none other than the Earl himself is suspected of the crime. As a violent storm rages on outside, the death count continues to climb. The Phantomhive household and their eminent guests find they must cooperate in order to solve this mystery before they too fall prey to the mysterious murderer. However, it seems that not even the perfect butler, Sebastian Michaelis, is safe from this horror.

Full of wonder and excitement, the Noah's Arc Circus troupe has captured audiences with their dazzling performances. Yet these fantastic acts don't come without a price. Children have mysteriously gone missing around London, correlating to that of the groups' 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. [Written by MAL Rewrite]
