Black Butler: Book of Circus

Noah’s Arc Circus has become a sensation in London, drawing crowds with spectacular performances that seem almost magical. But as the troupe travels, children begin disappearing in its wake, and the pattern is too consistent to ignore. At Queen Victoria’s request, her “guard dog” Ciel Phantomhive is sent to investigate—accompanied by Sebastian Michaelis, the impeccably loyal demon butler at his side.

To get close to the truth, Ciel and Sebastian go undercover among the performers, juggling rehearsals and new acts while quietly pursuing leads beneath the big top. As suspicion spreads within the circus and the presence of a shadowy benefactor hangs over their mission, the secrets they uncover threaten to cut deeper than Ciel expects.
