Kuroshitsuji: Book of Circus

Synopsis

Ciel and Sebastian begin their undercover job at the circus. Sebastian questions William about his intentions and the Grim Reaper reveals that in the next days, a huge number of souls are to be collected there. 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 members of the circus kidnap a young child at the city and the police appears to intervene, but all officers are killed by the members of the troupe. Back at the circus, the life on a different, more rough environment take a toll on Ciel's body, but he renews his vow to figure out the truth behind the circus as soon as possible.
