Sebastian Michaelis is a devilishly good butler who serves the head of the noble Phantomhive family. "Devilish" is to be taken literally, as Sebastian is indeed a demon with whom the Phantomhives have made a pact. Since then, Sebastian has not only held the most important position in the household staff but also serves as bodyguard and contract killer in one. His master is Ciel, the Earl of Phantomhive, who not only runs the family business but also serves as an important confidant to Queen Victoria in his role as Earl. She relies on the Phantomhives to discreetly and swiftly eliminate any threats. The Phantomhive household is dedicated to protecting the Empire from criminal and paranormal activities.
