The series follows Ciel Phantomhive, the thirteen-year-old (as of chapter 14) head of the Phantomhive family, an aristocratic family known as the Queen’s Watchdog, and tasked with solving crimes in London’s underworld. Ciel has formed a contract with Sebastian Michaelis, a demon who has taken on the disguise of Ciel’s butler, to seek revenge against those who killed his parents and resulted in him being kidnapped and tortured. In exchange for Sebastian’s service, he will be allowed to consume Ciel’s soul. The series has been licensed by Yen Press in North America and published in Yen Plus‘ August 2009 issue for the magazine’s first anniversary. In Victorian-era London lives the young boy, Ciel Phantomhive. On the night of his tenth birthday, a fire engulfed his manor house, his parents were murdered, and he was captured by a mysterious organization. After a month of enduring excruciating and humiliating torture, Ciel returns to the Phantomhive household with an enigmatic black-clad butler, Sebastian Michaelis. To others, it seems that the butler is simply the best at his craft, from anticipating his young master’s needs to carrying them out to the best of his inexplicable abilities.
Little do they know, Sebastian is actually a demon that has entered into a contract with Ciel, promising to help the boy achieve revenge on those who have wronged him in exchange for his soul. As the Queen’s guard dog and standing at the top of the British underworld, Ciel solves the crimes plaguing London while waiting for the day he will exact his revenge.
