Villain Overview

I am simply one hell of a butler.
~ Sebastian Michaelis (in the anime)
Human hearts are quite irksome, you see. Unlike the flesh, you cannot see or touch a human heart. And not even a devil or god can bind the heart of another in the truest sense of the word.
~ Sebastian Michaelis to Edward Midford.

Sebastian Michaelis (セバスチャン・ミカエリス, Sebastian Mikaerisu) is the titular deuteragonist of the manga and anime series Black Butler (Kuroshitsuji). He is the butler of the Phantomhive household and acts as Ciel Phantomhive’s bodyguard/butler, two jobs that he is completely devoted to.

He is voiced by Daisuke Ono (who also voices Jack Vessalius) in the Japanese version and J. Michael Tatum (who also voices Giriko and Shuu Tsukiyama) in the English dubbed version.


Sebastian takes on the appearance of a tall and handsome male adult with black hair and red eyes.

He typically dresses in an outfit; which consists of black trousers, a tailcoat, vest with the Phantomhive Crest on his shirt cuffs and a black 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 and he occasionally removes these, which reveals black fingernails.

True Demon Form[]

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, stilted pupils, and longer, sharper teeth. Prior to transforming.


Sebastian is a dutiful and dedicated butler to Ciel Phantomhive as he follows each order faithfully, while always ensuring that the Phantomhive house runs smoothly. However, whenever Sebastian sees a cat, he ignores whatever Ciel says to him. As such, he is noticeably annoyed whenever they end up behind schedule. The way he responds to Ciel's demands is quite notable, as the servants are pleased when they can successfully imitate the way he says "Yes, my lord" to Ciel.

Despite his ability to appear like a perfectly normal human, especially one who is able to smile, be cheerful, and be understanding, Sebastian is, in actuality, quite heartless, sadistic, and malicious. This comes out when he attacks others on Ciel's orders, such as when he kicked Grell Sutcliff's face because it was the thing that Grell wanted the least damage to. It is also shown with his cruel sarcasm and his inability to see good in much of anyone. At times, Sebastian can be indifferent and deliberately delays Ciel's wellbeing as he frequently teases him and has put his life in mild danger for his own amusement. Once, he responded to Ciel's kidnapping as "terrible" but only because the tea he prepared would go to waste. However, despite all the troubles he goes through on a daily basis, he has said that he doesn't think it's such a bad way of living.

Sebastian often contemplates about the nature of human beings. He seems to find humans, in general, to be "difficult creatures," but he also states that their struggles and lofty goals make them "interesting." He is also intrigued about how insatiable they are as they are willing to "drag others down to get what they want, even in death".


Sebastian's full name is similar to Father Sebastien Michaelis, who wrote a classification of demons in Hell.

  • The name Sebastian means "venerable" or "revered" in Latin.

  • Sebastion must fulfill Ciel's orders should he specifically say "this is an order". Such orders given to Sebastion include:

    • "Win the curry competition"

  • Sebastian was a guest at the Schönbrunn Place from time to time.
  • While fighting Ash Landers/Angela Blanc, Sebastian took his demon form.
    • In this form, there were feathers dropping on the ground. This may suggest, that his demon form is connected with a raven or crow.
  • It is possible that Sebastian is an ambidextrous (a person able to use the right and left hands equally well).
    • The meaning behind having the contract on his left hand is that the left hand was believed to be the hand of sin. It is implied that he is generally left-handed as he can be seen dueling with a sword in his left hand and when he writes, he also uses his left hand.
    • He plays the violin with his right hand.
  • In Kuroshitsuji II, it is stated that Ciel's soul was able to be stolen in the brief period when Sebastian's left arm was gone, the hand in which his contract seal lies.

  • In the extras of Volume 1, Yana Toboso said that Sebastian's age is a secret.
  • In the Victorian era, butlers were called by their last name.

    • In the anime, he appeared as a crow or raven accompanied by a rain of feathers.
    • In the manga, it seems that Sebastian was summoned accidentally.
    • But in the anime, it is made apparent that Ciel knew about the existence of demons and how to summon them all too well.
