In a manor house on the outskirts of Victorian era London, butler Sebastian Michaelis serves Lord Earl Ciel Phantomhive, the orphaned twelve-year-old head of an English noble family and a toy and candy empire, who serves directly under the Queen as her "guard dog". Master Phantomhives parents were murdered when Ciel was little. As a result, he made a pact with a demon asking for vengeance upon those who had disgraced him and the Phantomhive name, in exchange for his soul. Now, Sebastian carries out any task required by his Master, perfectly solving problems plaguing England with ease, due to his demonic lineage and the Faustian contract with Ciel.
