Sebastian Michaelis  

Black, Mr. Michaelis, Sebas-chan, セバスチャン・ミカエリス

Sebastian Michaelis is an artificial intelligence assistant that serves as the demon butler for the Phantomhive household. He often describes himself with the phrase "Because I am simply one hell of a butler," which plays on the word "demon" and "to the end." This phrase can also be translated to "I am a demon and a butler." Sebastian is highly skilled in any area and handles every task, no matter how difficult it may seem. He is able to solve problems that arise from errors made by other staff with ease due to his Faustian contract that binds him to Ciels will. A symbol similar to the one marking Ciels right eye can be found on Sebastian's left hand, which he has used once to twist a kidnapper's arm without touching him.
