Black butler. 6. [graphic novel]

The cheer of the holidays has passed, but the Noah's Ark traveling circus has been making the rounds, bringing fun and joy to children of all ages. However, as the ringmaster's cries fade away, a disturbing trend begins to surface in the wake of the colourful entourage. Children seem to disappear whenever the circus packs up for its next destination, and there are no clues, or corpses, to be found. But when the situation calls for Ciel and Sebastian to infiltrate the big top, will Sebastian's inhuman skills be enough to see him and his young master through a treacherous tightrope act that may well end in death?
