Race: Demon
Height: 185 (6'1")

Appearance
Sebastian takes on the appearance of a tall, male adult with black hair and red eyes. He typically dresses in an outfit that consists of black trousers, a tailcoat, and a vest. He has the Phantomhive crest on his shirt cuffs and on his tie. He also sports a pocket watch with a chain, and a chained silver lapel pin bearing the Phantomhive Crest, traditionally worn by the house's head butler.
His white gloves conceal the mark of his Faustian contract with Ciel Phantomhive on his left hand. He occasionally removes these, revealing black fingernails.
Sebastian's demonic form has never been fully shown. Details of this form include high-heeled stiletto boots, a shower of black feathers, sharp claws, glowing fuchsia irises, slitted pupils, and longer, sharper teeth. Prior to transforming, Sebastian says several times that his form is unpleasant to look at. Just looking at it drove Ash Landers to hysterics, screaming that he was "unclean."
Personality
Sebastian is a dutiful and dedicated butler to Ciel Phantomhive. He follows each order faithfully, while always ensuring that the Phantomhive house runs smoothly. He does not sleep, except as a luxury, and frequently performs tasks for Ciel at night. The manner in which he responds to Ciel's demands is quite notable, as the servants are pleased when they can successfully imitate him; he says, "Yes, My Lord."
The name Sebastian is in fact a temporary name given to him by Ciel and was previously held by Ciel's dog. He bears a striking resemblance to Ciel's father. In the anime adaption, Sebastian can take the form of a crow. Sebastian's true demonic form has not been fully revealed. However, a depiction of sharper teeth, high-heeled boots, and elongated nails have been given. In the manga adaptation, Sebastian appears to Ciel in his true form, while in the anime version, he appears as a crow. His name is similar to that of Father Sebastien Michaelis, who compiled a hierarchy of demons in Hell.
Sebastian often describes himself through the phrase "Because I am one hell of a butler" (わたしはあくまで執事ですから, Aku made 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". He is highly skilled in any area and handles every task, no matter how impossible it is as well as any problem that arises from the errors of the other staff with ease, stating it is only natural as the butler to the Phantomhive family. This is due to the fact he is a demon bound by a Faustian contract to abide by Ciel's will. A sign similar to the one marking Ciel's right eye can be found on Sebastian's left hand, which has been used on one occasion to twist the arm of a kidnapper without touching him.
Despite his appearance as a courteous and excellent servant, Sebastian is, in actuality, a heartless, sadistic, and malicious demon. He is ruthless when he attacks others on Ciel's orders, such as when he kicks Grell Sutcliff's face because it is the thing that Grell most cherishes. His diabolical nature is also shown through his cruel sarcasm and his inability to see good in much of anyone. At times, Sebastian can be indifferent, and he deliberately delays Ciel's well-being, frequently teases him and has put his life in mild danger for his own amusement. He calls Ciel a "brat" who treats his workers rudely.However, despite all the troubles he goes through on a daily basis, he says that he does not dislike the butler lifestyle.
Sebastian views money as "rubbish" and is more than willing to give out generous amounts of pocket money given to him. He is fluent in French and Latin, enough to teach the latter. Sebastian has a strong distaste for Shinigami, a feeling that is returned. He greatly favors cats, and he keeps at least thirteen cats or more hidden in his closet, to make sure Ciel does not find out.
Sebastian often contemplates about the behaviors and attitudes of human beings. He finds humans, in general, to be "difficult creatures," but he adds that their struggles and lofty goals make them interesting. He is intrigued about how insatiable they are, as they are willing to "drag others down to get what they want, even in death."
