Ciel Phantomhive (シエル・ファントムハイヴ, Shieru Fantomuhaivu) is the business-savvy, twelve-year-old head of the English Phantomhive noble family, taking over after the deaths of his parents. He also runs a company that manufactures toys and sweets. His right eye, which is usually covered with a black eyepatch, bears a pentacle sign of contract which binds the demon Sebastian Michaelis to his will. He also has a symbol burned into his back during the time he was traded around as a slave before Sebastien saved him, which is something he does not like for others to see. It is suggested that he ultimately looks at Sebastian as a knight, like in a chess game. He is close to his cousin and fiancée Elizabeth, seeing her as an important friend and someone he needs to protect. Although he is usually portrayed as emotionless, it is revealed that he does not want to lose anything important to him again. Ciel once owned a dog named Sebastian, but lost him along with his parents in a fire. He is voiced by Miyuki Sawashiro on the first drama CD and Maaya Sakamoto in the anime adaption and on the second drama CD.
Sebastian Michaelis (セバスチャン・ミカエリス, Sebasuchan Mikaerisu) is the series' protagonist. He is the butler of the Phantomhive household and Ciel's bodyguard, two jobs he is completely devoted to. 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 "contract" to abide by Ciel's will. A sign similar to the one marking Ciel's right eye can be found on his left hand. The name Sebastian is in fact a temporary name given to him by Ciel and previously held by Ciel's dog. He is voiced by Toshiyuki Morikawa on the first drama CD and Daisuke Ono in the anime adaption and on the second drama CD.  His name is similar to that of Father Sebastien Michaelis, who compiled a hierarchy of demons in Hell. In the anime adaption, Sebastian can be seen in the form of a crow.
