Full of wonder and excitement, the Noah's Arc Circus troupe has captured audiences with their dazzling performances. Yet these fantastic acts do not come without a price. Children have mysteriously gone missing around London, correlating to that of the group's movements. Unsettled by these kidnappings, Queen Victoria sends in her notorious guard dog, Ciel Phantomhive; and his ever-faithful demon butler, Sebastian Michaelis, on an undercover mission to find these missing children.
