Kuroshitsuji

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 Phantomhive's 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.

Sebastian Michaelis

Sebastian Michaelis (セバスチャン・ミカエリス, Sebasuchan Mikaerisu) is the butler of the Phantomhive household and acts as Ciel's bodyguard. Sebastian often describes himself through his catchphrase "I am simply one hell of a butler" (私はあくまで執事ですから, Watashi wa akuma de shitsuji desu kara^?). The phrase plays on the word "demon" (あくま, akuma^?) and the phrase "to the end" (あくまで, aku made^?). It can also translate to "I am a demon and a butler". In Funimation's English translation, this phrase becomes "I am a devilishly talented butler" or "I am one hell of a butler" which is, obviously, another play on his demonic origins.
He has been described by multiple women (Madame Red, city women, nun in anime) throughout the anime and manga series to be extremely attractive and seductive.
Being a butler is a job he is completely devoted to. He follows Ciel's orders faithfully, however, he does not seem to be overly concerned about Ciel's well-being most of the time, as he insults and irritates Ciel to see his reaction. However, occasionally he does appear to care about Ciel at times, such as in the Noah's Arc Circus arc where he was worried when Ciel had an asthma attack, and again later on when Ciel had a panic attack. He calls Ciel a "brat" who treats his workers rudely. Sebastian is also shown to be obsessed with cats, kittens, wild catlike beasts, and so on; in chapter 44 of the manga, he is shown to be hiding 15 cats in his room. In chapter 49, it is shown that he had found the cats outside in the rain when he was doing a task for Ciel, and he just couldn't leave them outside. He also appears to love a stray black cat with amber eyes, who occasionally appears near the Phantomhive household or inside the household's garden, waiting for him. Comically, the only times he does not follow Ciel's orders are when he sees a cat, too preoccupied with it to pay any attention to anything else. This occurred in the second season of the anime when he sees a mother cat with her kittens, and Ciel calls him a "cat obsessed moron." Also, he doesn't appear to hear anything that Ciel says when he is looking at a black cat in the alley they are hiding in right before Mary Jane Kelly is murdered. He has an extreme aversion to dogs, and it was much to his dismay when Pluto the hell hound came to stay at the manor.

Ciel Phantomhive

Earl Ciel Phantomhive (シエル・ファントムハイヴ, Shieru Fantomuhaibu) born on December 14, 1875 is the business-savvy, egotistical 12-year-old (13-year-old as of chapter 14) and the head of the English Phantomhive noble family after the deaths of his parents, Lord Vincent Phantomhive and Lady Rachel Phantomhive. He runs the Funtom Company, which manufactures toys and sweets, with the later addition of a food branch after winning a Royal Warrant. His right eye, which is usually covered with a black eye patch, bears a pentacle, the sign of the Faustian contract he made with the demon Sebastian. Sebastian says that the mark on Ciel is proof of their contract. He also says that demons mark their prey so that they can locate them.
After his parents' deaths and prior to meeting Sebastian, he was a slave and a sacrifice in a cult ritual. During one particular instance where Ciel was being tortured, his hatred for his torturers summoned Sebastian. He then commanded the demon to kill all the people in the room. During his time as a slave, a mark was burned into his back; in the anime adaption, it is found on his left side, near his chest. In the manga the mark is found on the left side of his back. He does not want anyone to see this mark and appears to not enjoy physical contact (possibly aphephobic), though he tolerates Sebastian and does not complain when the demon picks him up or holds him. If stressed, he will slap someone touching him away, proclaiming "Don't touch me so easily!" He also once pointed a gun at Sebastian that he had hidden underneath his pillow, for he was having a nightmare of being tortured (supposedly provoked from reading Edgar Allan Poe before bed). This is a negative influence of the trauma he underwent during his time as a slave.
He is usually portrayed as emotionless, cold, boring, not fun, rude, and un-childlike, though he occasionally expresses concern for the well-being of the few close to him; Sebastian is not one of those people. He sometimes portrays himself as a happy person (mostly when undercover), but soon returns to his true self. Whether he worries for Sebastian's well-being or not is unknown, but ultimately he sees Sebastian as a pawn. Although, that said, there was one time that proved Sebastian was the most important person to him. There have been times when he wishes for Sebastian to fail at a task or request for humor's sake. He is close to his cousin and fiancée Elizabeth, seeing her as an annoying cute friend, the marriage was arranged. Before the loss of his parents, Ciel seemed to be a happy childlike child.



  Humans are easily tempted. When they are poised on the edge of hellish despair and a spider's thread of salvation presents itself, they will invariably grasp it... no matter the manner of human. — Sebastian Michaelis in Chapter 12
