ข้อมูลอนิเมะBlack Butler

Ciel Phantomhive is awakened by his butler, Sebastian Michaelis, who informs Ciel that Damian, the head of one of his factories, is coming for a visit. Sebastian orders the household staff, Baldroy, the cook, Finnian, the gardener, and Mey-Rin, the maid, to prepare for Damian's arrival. However, their attempts result in disaster, as Baldo overcooks the food, Finnian kills the garden by spraying herbicides on it, and Mey-Rin breaks all of the china. To resolve the situation, Sebastian orders them to rearrange the yard into a stone Japanese garden and has Bard make beef tataki. Damian, impressed with the staff's preparations, plays a board game with Ciel in which his character loses his legs and is ultimately incinerated. Following the dinner, Damian calls his associate, commenting that the factory he owns has been sold and he is attempting to fraudulently acquire more money from Ciel. When Damian attempts to return to the lounge, the scenario in the game occurs in real life, as he breaks one of his legs, and Sebastian locks him in the oven, to be burned with the dessert. He later runs away from the mansion.

Ciel is kidnapped for ransom, but Sebastian easily defeats a mob of underlings, with various kitchen supplies, and retrieves his master.

Elizabeth, Ciel's fiancee, arrives at the Phantomhive Estate for a visit. While Ciel does not wish to dance with her, Sebastian convinces him to learn to dance for the sake of preserving his social reputation, and teaches him a simple waltz. Later, Elizabeth is unhappy with Ciel wearing his own ring in favour of the one she has brought him, and she breaks Ciel's ring by throwing it on the floor. Ciel comes close to hitting Elizabeth but is stopped by Sebastian, who explains to Elizabeth that Ciel's ring is the Phantomhive family's ring. Elizabeth is upset, but Ciel throws the ring out of the window and declares that he is the head of the Phantomhive family, with or without it. Ciel then wipes Elizabeth's tears away and dances with her. That night, Sebastian finds Ciel depressed in bed and produces Ciel's ring, undamaged. Ciel wonders how many Phantomhives have died wearing the ring. He tells Sebastian to stay by his side until he falls asleep, amusing Sebastian and causing him to comment on Ciel showing his weaknesses to him.

The news of Jack the Ripper terrorizes the city of London. Sebastian narrows the suspects down to a single man, a Viscount. Madame Red creates a plan for Sebastian, Ciel and Lau to attend a ball to catch the culprit, which involves Ciel wearing a dress and Sebastian pretending to be his tutor. They realise that Elizabeth is attending the ball and dance across the ballroom to avoid her because she would then blow there cover and then they would get caught.As Ciel says that Elizabeth has too much energy. The Viscount takes a liking to Ciel, who attempts to seduce him, while Sebastian distracts Elizabeth and the other guests by pretending to be a magician and gets trapped in a box with all these knifes and chains with using only magic as he says(which is true). Alone in a room with the Viscount, which turns out has a smell that Ciel thinks its just a smell,then Ciel loses consciousness, later awaking to find himself being sold in a large underground auction, tied and blindfolded. When the Viscount removes the blindfold in order to display Ciel's eyes, the latter keeps them closed. After a moment, he opens them and calls for Sebastian. The lights go out, and the cries of many people are heard and the candles are suddenly relit to reveal Sebastian, who takes Ciel home as the police arrive at the scene.

Ciel and Sebastian continue to pursue Jack the Ripper and come to a confrontation at the house of the latest victim, Mary Kelly. They discover that the murderer is a combination of Madam Red and Grell Sutcliff, her seemingly bumbling butler, who is actually a Reaper. While Sebastian is busy fighting Grell, Madam Red attempts to kill Ciel, but she sees her sister's face in his and is unable to do so. Grell kills Madam Red because of this and her life is played back before his eyes, as Reapers can see a person's memories as they die. It is revealed that she loved Ciel's father, but he chose Rachel, her sister, over her. Eventually, she found someone she loved and married him, and was to have a child, but an accident killed her husband and caused the doctors to have to abort her baby and take out her womb to save her life, rendering her infertile. When one of her patients came to her and asked for an abortion, claiming children were a nuisance, something in her snapped and she followed the patient later that night and killed her. It was then that she met Grell, and the two of them murdered people as Jack the Ripper since then. Sebastian is ordered by Ciel to kill Grell.

Sebastian ends Jack the Ripper's reign of terror. Later, Ciel and Sebastian attend Madam Red's funeral and visit the grave of Jack the Ripper's last victim.

By the command of the Queen, Ciel is to secure Houndsworth, a village controlled by a nobleman Henry Barrymore. The supposed resort that the company was in for is, in fact, a dark and dreary place inhabited by a demon dog.

Ciel and his servants confront the real demon dog of the village of Houndsworth and end up taking it home.

Ciel assigns his servants to take a photo of Sebastian with a camera that reveals what is most precious to the subject that is not of this world (e.g., dead things). Sebastian evades their efforts over and over again effortlessly. In the end, Sebastian takes a photo of Ciel, who had fallen asleep at his desk, with Pluto behind him at the back window which leads to an amusing photograph that confuses the rest of the servants at the mansion. Sebastian later comments that it was an honor to learn that the thing Ciel most treasures that is not of this world is Sebastian himself. (Sebastian is a demon, therefore he is able to show up in the photo because he is not someone of the normal world). Later, Finny wonders how Sebastian can show up as he thinks that Sebastian is someone of this world.
