Black Butler: Emerald Witch Arc

In Victorian-era Europe, a young boy loses everything he once held near and dear to a vicious plot. In his moment of death, he strikes a deal with a demon: his soul, in exchange for revenge. Ciel Phantomhive is now the head of the Phantomhive corporation, handling all business affairs as well as the underground work for the Queen of England. His new partner is a demon butler, Sebastian Michaelis, whose powers as a butler is only surpassed by his strength as a demon. The story follows the two along with their other servants, as they work to unravel the plot behind Ciel's parents' murder, and the horrendous tragedies that befell Ciel in the month directly after.

In late-nineteenth century England, one year and three months after the dramatic conclusion of the original series, Kuroshitsuji II introduces a new butler and young master. The sadistic yet cheerful Alois Trancy has faced some harsh times. He was kidnapped as a baby, and was forced to work in a village as a slave. Gradually, he lost his parents, his brother, and everyone he knew. Alois eventually returned home and became the head of his mansion, but seemed to exhibit some strange behavior ever since. Even more curiously, he returned with Claude Faustus, an enigmatic, emotionless butler with unfathomable talent...

Continuation of the Kuroshitsuji anime adaptation. At the request of Queen Victoria, Earl Ciel Phantomhive goes to Weston College—a prestigious public academy for boys, known for its traditions and outstanding curriculum—to search for a relative of hers who has not returned home in months. Thanks to his noble status, the 13-year-old Ciel is swiftly able to enroll as a student, while his devilish butler Sebastian Michaelis assumes a teaching position at the school. Ciel does not anticipate being unable to locate the Queen's relative on campus. To make matters worse, he cannot request a meeting with the headmaster of the college, who may be the only person that knows anything pertaining to the disappearance. The only ones in frequent contact with the headmaster are the heads of the college dormitories, known as the Prefect 4 (P4): Edgar Redmond, Lawrence Bluewer, Herman Greenhill, and Gregory Violet. Ciel must concoct a plan to get in the P4's good graces if he wants to use their connections to succeed in his mission. But the distinguished college and its students hide much that is unseen, making this task more improbable than he could imagine.

In late-nineteenth-century England, the Noah's Ark Circus enlivens the city of London with their grandeur and spectacular stunts. However, children are mysteriously disappearing from the town in a manner correlating to the troupe's movement. The Queen, then, sends her notorious Watchdog, Ciel Phantomhive, on an investigative mission to retrieve the missing children. Ciel and his demon butler, Sebastian Michaelis, infiltrate the circus, disguised as team members, to study and possibly unearth its ulterior motive. This arc immediately follows the Curry Contest Arc in the manga, which ended at episode 15 in the first season of the anime.
