Episodes
A new day begins at the Phantomhive Estate and guests are expected for a business meeting that evening. Lau and Ran-Mao arrive with Cedric Brandel, a businessman who secretly intends to have Ciel killed as Ciel's position as the Queen's guard dog is interfering with his illegal arms trade. However, just when he orders his men to attack, Cedric learns that Sebastian had already dealt with all of them and is killed by the butler. Lau delivers an invitation for the Circus that has just arrived in the city. Sebastian puts Ciel to sleep, eagerly awaiting the day when he will claim his master's soul.
The Queen orders Ciel to investigate the circus' possible connection with missing children as children have vanished from every town the circus has visited. Ciel and Sebastian attend the circus and Sebastian volunteers for one of the acts. A commotion is caused when he finds himself enticed, then attacked, by the tiger. Joker, the ringleader, insists that Sebastian be examined by their doctor. The butler's curiosity is piqued when he finds that many of the performers wear prosthetic limbs made by the doctor. Sebastian asks Joker for a job, and upon being accepted, agrees to return the next day with an "acquaintance" who also wishes to join. Sebastian then tries to investigate the circus further but the snake charmer Snake stops him.
After a brief reunion with Soma and Agni, Sebastian and Ciel return to the circus in the next day to become part of it. But Ciel's abilities are yet to prove, and he is forced to participate in two trials, one of throwing knives and another of tightrope walking, succeeding on both with Sebastian's help. However, once accepted into the circus, the duo discover, much to their surprise, that William T. Spears is also working there undercover, and realize that there is something truly suspicious occurring in Noah's Ark Circus, to the point of having a Grim Reaper personally investigating it.
Ciel and Sebastian begin their undercover job at the circus. William reveals that in the next days, a huge number of souls are to be collected at the circus. While Ciel is paired with another recruit called "Freckles", Sebastian is assigned to sleep in the same tent as William, much to each other's dismay. Later at night, the first-string circus members kidnap a young child in the city, killing all the police officers who intervene. At the circus, the rougher environment take a toll on Ciel's body, but he vows to figure out the truth behind the circus as soon as possible.
Ciel and Sebastian intend to look for clues in the first-string members' tents while they are performing. However, Ciel is left alone when Sebastian and William are summoned to replace injured artists. He finds a mysterious symbol of status in old photos and a letter addressed to Joker that states Ciel's name and biographical information. Ciel is saved from a snake by Doll, one of the main performers, and learns that she is in fact his roommate Freckles. He has a sudden asthma attack, brought on by the abrupt stress and cold. Though bedridden, he sends Sebastian to investigate further. Snake discovers that the duo is spying on them and Joker decides to consult with "Father" before taking action.
Ciel Phantomhive, the queen's watchdog, is given two tickets to go to a traveling circus for himself and his demon butler, Sebastian. His job is to enter the circus and look for multiple missing children that are believed to be abducted.
