Black Butler (黒執事 Kuroshitsuji?) is a manga written and illustrated by Yana Toboso. Since its debut on September 16, 2006, it has been serialized in Square Enix's shōnen manga magazine Monthly GFantasy. The series follows Sebastian Michaelis, a demonic butler who is bound by a supernatural contract to serve Ciel Phantomhive, the twelve-year-old head of the Phantomhive noble family, and in return Sebastian will obtain Ciel's soul when Ciel has finished getting his revenge and allows Sebastian to kill him. It was announced in July 2008 that an anime adaption, directed by Shinohara Toshiya and produced by A-1 Pictures, was expected. It premiered in October 2008, and has since ended with 24 episodes. However, at the Sono Shitsuji, Shūshō: Saigo no Bansan o Anata to Tomo ni (その執事、終章 ～最後の晩餐を貴方と共に～?, "That Butler, Last Chapter ~a last supper with you~") event on June 14, 2009, it was announced that the anime will be returning for a second season. Voice actor Junichi Suwabe confirmed this news on his official blog later that day. The second season premiered in Japan on July 1, 2010 on MBS and will span 13 episodes. 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.
