Canon
Back before Ciel’s parents died, Sebastian was already their butler before their deaths. Cause a suspended Ciel Phantomhive intentionally summons a demon, later named Sebastian Michaelis for his aid in an unknown location.

Sebastian awakes Ciel for the day and informs him of the day's plans, which include welcoming a guest from a manufacturing company, Poseidon Company. As Sebastian turns to leave, Ciel throws a dart at his head, which he effortlessly catches.

Sebastian goes to work on the preparations for Damian when he is called by Ciel. The other servants decide to help with the preparations in order to impress Sebastian. Sebastian speaks to Ciel who requests a parfait, which Sebastian refuses to make, lest he later not be hungry enough to eat dinner. Ciel then orders Sebastian to remove the family portrait, as he is now the head of the Phantomhive estate.

In episode 2, Ciel is kidnapped by Azzurro Vanel and Sebastian goes to rescue him. Azzurro threatens to kill Ciel, and Ciel and Sebastian banter over the next action to take. Azzurro fires the gun, but is unable to kill Ciel because Sebastian has caught the bullet. Sebastian, then, grabs Ciel and unties him, while Azzurro begs for his life and tries to bribe him. However, Sebastian declares that he has no interest in the "waste made by man," and explains that he is a demon. He transforms into his true form, while explaining the Faustian contract he has with Ciel. It is assumed that he kills Azzurro.

Afterward, Ciel and Sebastian return to the manor, where they are warmly greeted by the rest of the Phantomhive household. Sebastian then apologizes for his failure to prepare dinner.

In episode 3, Sebastian questions if his refusal to dance is because he cannot dance. Ciel attempts to dismiss him, but Sebastian points out how important it is for a man of his social standing to be able to dance. He then goes into tutor mode and teaches him how. That night, Sebastian reveals that he fixed the ring after Lizzy broke it, and returns it to Ciel. Spooked by how many times the ring has seen death, Ciel asks Sebastian to stay until he falls asleep, and Sebastian chuckles, commenting how amusing it is that he sees Ciel's weaknesses.

In episode 4, In order to get closer to Aleister, Ciel and Sebastian dance, which attracts Aleister's attention. Sebastian takes his leave, so he can speak privately with Aleister. While talking, Elizabeth takes notice, and attempts to come over, but Sebastian stops her, by pretending he was hired as a magician. He gets Lau to help him, and they put on a magic show, while Ciel and Aleister slip away. In another room, Aleister drugs Ciel with a gas, which knocks him out. When he awakes, he finds himself tied up and blindfolded in a room where Aleister is auctioning him off. Thinking this is proof enough, Ciel calls for Sebastian who comes to his aid. As he has already called the Scotland Yard, Sebastian carries him away from the manor.

In episode 6, Sebastian then apologizes to Ciel for not killing Jack the Ripper but says it does not matter anymore. Ciel wobbles when he stands, and Sebastian attempts to steady him, but Ciel slaps him, saying he is only tired. Sebastian also says Ciel is either kind or weak, saying it was his hesitation to kill a relative, even one who was killing him, that prevented him from firing. Ciel deflects, though, saying it is Sebastian's job to protect his life. Ciel orders Sebastian to never betray or leave him, which he agrees to.

In episode 9, there is a moment where it looked like Sebastian was going to kiss him until the fireworks interrupted. Later, He goes to bring Ciel to bed, but finds he is already sleeping. While he is sleeping, Sebastian takes a photo of Ciel, and it is shown that the person Ciel cares about most, who is also "not of this world," is Sebastian. The photo, however, confuses the staff, as Pluto is also present, making them wonder who it is that Sebastian cares for, as they assume he is of this world.

At breakfast, Sebastian teases Ciel for this, telling him that he is honored, and Ciel tells the bastard to shut up.

In the Black Butler movie: book of murder, Ciel discovers that Sebastian is killed and refuses to believe he's dead and thinks he's messing with him. But Ciel soon comes to realization and cries over Sebastian's dead body.

- Ciel to Sebastian, after seeing his death.

Fanon
SebaCiel is the most popular ship in the fandom, due to how close they are in the anime. However, it receives a lot of backlash and hate from fans due to being pedophilia with Ciel being a 12 to 13-year-old boy and Sebastien being over a thousand years old as well as having the appearance of an adult with many fanfictions that involve Ciel as an adult and demon with Sebastien and him bonding together.

Their relationship could also be considered unhealthy since Sebastian plans on devouring Ciel's soul after finding and killing the boys parents killers. Because of this, many fans prefer to ship SebaGrell instead thanks to Grell canonical having a crush on Sebastian along with them being both old enough to be shipped properly.
